Cervical Disk Replacement Versus Anterior Cervical Diskectomy and Fusion: Effect of Procedural Variant on Patients With a Prolonged Preoperative Duration of Symptoms From Disk Herniation. J Am Acad Orthop Surg 2024:00124635-990000000-00950. [PMID: 38696821 DOI: 10.5435/jaaos-d-23-00655] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2023] [Accepted: 02/17/2024] [Indexed: 05/04/2024] Open
Abstract
INTRODUCTION Patients with a prolonged preoperative symptom duration (PSD) in the setting of cervical disk herniation (DH) may suffer inferior outcomes after surgical intervention. Comparison between anterior cervical diskectomy and fusion (ACDF) versus cervical disk arthroplasty (CDA) in this at-risk population has not yet been conducted. METHODS Patients undergoing ACDF or CDA for DH with a PSD > 180 days were selected. Six-week (6W) and final follow-up (FF) patient-reported outcome measures (PROMs) as well as magnitude of postoperative improvements (∆PROM) were compared between cohorts using multivariable linear regression. Intercohort achievement rates of minimal clinically important difference (MCID) in each PROM were compared. RESULTS Seventy-seven of 190 patients were in the CDA cohort. 6W Patient-Reported Outcomes Measurement Information System-Physical Function (PROMIS-PF) was superior in the CDA cohort. The ACDF cohort demonstrated notable improvements in the 6W Neck Disability Index (NDI), visual analog scale-neck pain (VAS-N), visual analog scale-arm pain (VAS-A), and 9-item Patient Health Questionnaire (PHQ-9). The CDA cohort demonstrated notable improvements in 6W PROMIS-PF, NDI, VAS-N, and VAS-A. FF VAS-A was better in the CDA cohort. The ACDF cohort demonstrated notable improvements in FF PROMIS-PF, NDI, VAS-N, and VAS-A. The CDA cohort demonstrated notable improvements in all FF PROMs. ∆PROM-6W in PROMIS-PF was greater in the CDA cohort. CONCLUSION Patients with prolonged PSD due to cervical DH demonstrated notable improvements in physical function, disability, pain, and mental health regardless of fusion versus arthroplasty techniques. Accounting for demographic variations, patients undergoing CDA demonstrated a greater magnitude of improvement and superior scores in physical function at the first postoperative follow-up. Rates of clinically tangible improvements in PROMs did not markedly vary by surgical procedure. Patients undergoing CDA may perceive greater early improvements to physical function compared with patients undergoing ACDF for prolonged PSD due to DH.

Effect of Baseline Veterans RAND-12 Mental Composite Score on Postoperative Patient-Reported Outcome Measures for Cervical Disk Replacement. Clin Spine Surg 2024; 37:E147-E151. [PMID: 38178315 DOI: 10.1097/bsd.0000000000001558] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Accepted: 10/03/2023] [Indexed: 01/06/2024]
Abstract
STUDY DESIGN Retrospective review. OBJECTIVE To examine the effect of baseline Veterans RAND-12 (VR-12) Mental Composite Score (MCS) on clinical outcomes in patients undergoing cervical disk replacement (CDR) for herniated disk. BACKGROUND Few studies in spine surgery have evaluated the impact of preoperative VR-12 MCS on postoperative outcomes in patients undergoing CDR. METHODS Patients undergoing CDR for herniated disk were separated into 2 cohorts based on the VR-12 MCS standardized mean: VR-12 MCS<50 (worse mental health) and VR-12 MCS≥50 (better mental health). Patient-reported outcome measures of VR-12 MCS, VR-12 Physical Composite Score, Short Form-12 (SF-12) MCS, SF-12 Physical Composite Score, Patient-Reported Outcomes Measurement Information System Physical Function, Patient Health Questionnaire-9 (PHQ-9), Visual Analog Scale (VAS) Neck Pain, VAS Arm Pain, and Neck Disability Index were collected at preoperative and up to 2-year postoperative time points. RESULTS In all, 109 patients were identified, with 50 patients in the worse mental health cohort. The worse mental health cohort reported inferior patient-reported outcome measures in all domains at preoperative, 6-week postoperative, and final postoperative time points. For 6-week postoperative improvement, the worse mental health cohort reported greater improvement for VR-12 MCS, SF-12 MCS, and PHQ-9. For final postoperative improvement, the worse mental health cohort reported greater improvement in VR-12 MCS and SF-12 MCS. Minimum clinically important difference achievement rates were higher in the worse mental health cohort for VR-12 MCS, SF-12 MCS, and PHQ-9. CONCLUSION Patients undergoing cervical disk replacement for herniated disk with worse baseline mental health reported inferior clinical outcomes in mental health, physical function, pain, and disability outcomes throughout the postoperative period. Patients with worse baseline mental health demonstrated greater clinically meaningful improvement in mental health. In cervical disk replacement patients, those with worse baseline mental health may report inferior postoperative clinical outcomes but experience greater rates of tangible improvement in mental health.

The Surgical Learning Curve for Cervical Disk Replacement. Clin Spine Surg 2024; 37:E82-E88. [PMID: 37684720 DOI: 10.1097/bsd.0000000000001530] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Accepted: 08/10/2023] [Indexed: 09/10/2023]
Abstract
STUDY DESIGN Retrospective study. OBJECTIVE To characterize an experienced single surgeon learning curve for cervical disk replacement (CDR). SUMMARY OF BACKGROUND DATA A single surgeon learning curve has not been established for CDR. METHODS Patients undergoing CDR were included. The cumulative sum of operative time was utilized to separate cases into 3 phases: learning, practicing, and mastery. Demographics, perioperative characteristics, complications, patient-reported outcomes (PROs), and radiographic outcomes were collected preoperatively and up to 1 year postoperatively. PROs included Patient-reported Outcomes Measurement Information System Physical Function, 12-item Short Form-12 Physical Component Score, 12-item Short Form-12 Mental Component Score, visual analog scale (VAS) arm, VAS neck, Neck Disability Index. Radiographic outcomes included segmental angle/segmental range of motion/C2-C7 range of motion. Minimum clinically important difference achievement was determined through a comparison of previously established values. RESULTS A total of 173 patients were identified, with 14 patients in the learning phase, 42 patients in the practicing phase, and 117 patients in the mastery phase. Mean operative time and mean postoperative day 0 narcotic consumption were significantly higher in the learning phase. The preoperative segmental angle was significantly lower for the learning phase, though these differences were eliminated at the final postoperative time point. Patients in the learning phase reported worse improvement to 6-week postoperative, final postoperative, and worse overall final postoperative VAS Arm scores compared with practicing and mastery phases. CONCLUSIONS For an experienced spine surgeon, the learning phase for CDR was estimated to span 14 patients. During this phase, patients demonstrated longer operative times, higher postoperative narcotic consumption, and worse postoperative VAS Arm scores. Radiographically, no postoperative differences were noted between different phases of mastery. This single surgeon learning curve demonstrates that CDR may be performed safely and with comparable outcomes by experienced spine surgeons despite decreased operative efficiency in the learning phase.

Obesity Does Not Negatively Affect Patient-perceived Outcomes After Cervical Disc Replacement for Disc Herniation. Clin Spine Surg 2024:01933606-990000000-00251. [PMID: 38245814 DOI: 10.1097/bsd.0000000000001562] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/22/2023] [Accepted: 11/29/2023] [Indexed: 01/22/2024]
Abstract
STUDY DESIGN Retrospective review. OBJECTIVE To assess the impact of Body Mass Index (BMI) on patient-reported outcome measures (PROMs) after cervical disc replacement (CDR). BACKGROUND BMI may affect PROMs after spine surgery. METHODS Primary CDR recipients for herniated disc(s) with BMI <40 were retrospectively selected from a single-surgeon registry. Cohorts were divided into non-obese (BMI <30) and obese (BMI ≥30). Intercohort in-hospital complication rates were compared through independent samples t tests. Pre/postoperative PROMs were compared between cohorts through multivariable regression accounting for demographic differences. Final follow-up dates between patients averaged 11.8 ± 9.3 months. PROMs assessed included Patient-reported Outcomes Measurement Information System-Physical Function, Neck Disability Index, Visual Analog Scale-Neck, Visual Analog Scale-Arm, and the 9-item Patient Health Questionnaire. Improvements in PROMs were evaluated and compared at each follow-up within cohorts through paired t tests. The magnitude of improvement in PROMs from preoperative baseline at 6-week follow-up (∆PROM-6W) and final follow-up (∆PROM-FF) along with achievement rates of minimum clinically important differences were compared between cohorts through multivariable regression accounting for demographic differences. RESULTS Of 153 patients, 53 patients were noted as obese. Demographic differences included age, prevalence of hypertension and diabetes, and comorbidity burden scores (P ≤ 0.011, all). No significant variations in in-hospital complications were found. The non-obese cohort demonstrated improvements in all PROMs at 6 weeks and final follow-up periods (P ≤ 0.005, all). The obese cohort demonstrated improvements in all postoperative PROMs besides 9-item Patient Health Questionnaire at 6 weeks (P ≤ 0.015, all). After accounting for age and comorbidity variations, there were no significant intercohort differences in raw PROM scores, ∆PROM-6W, ∆PROM-FF, or minimum clinically important difference achievement rates. CONCLUSIONS Regardless of BMI, patients experience significant improvements in physical function, disability, pain, and mental health after CDR for disc herniation. Patients with obesity do not suffer inferior patient-perceived outcomes after CDR. These findings may help surgeons counsel patients in the preoperative period.

Impact of Preoperative Symptom Duration on Patient-reported Outcomes After Minimally Invasive Transforaminal Interbody Fusion for Degenerative Spondylolisthesis. Clin Spine Surg 2024:01933606-990000000-00252. [PMID: 38245808 DOI: 10.1097/bsd.0000000000001560] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/25/2023] [Accepted: 11/29/2023] [Indexed: 01/22/2024]
Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVE To assess the impact of preoperative symptom duration (PSD) on patient-reported outcome measures (PROMs) after minimally invasive (MIS) transforaminal lumbar interbody fusion (TLIF) for degenerative spondylolisthesis (DSpond). BACKGROUND A prolonged duration of preoperative symptoms may implicate inferior long-term outcomes postsurgery. Prior studies of lumbar fusion recipients are limited by the inclusion of heterogeneous populations. METHODS A single-surgeon registry was retrospectively queried for privately insured patients who had undergone primary, elective, single-level MIS-TLIF for DSpond with a recorded symptom start date. Cohorts were formed by PSD: shorter duration (PSD <1 y) or greater duration (GD; PSD ≥1 y). PROMs evaluated included Patient-reported Outcomes Measurement Information System-Physical Function, Oswestry Disability Index, Visual Analog Scale-Back, Visual Analog Scale-Leg, and 9-item Patient Health Questionnaire. The magnitude of PROM (∆PROM) improvement from preoperative baseline to 6 weeks and final follow-up (∆PROM-FF) were compared between cohorts. Intercohort achievement rates of a minimum clinically important difference in each PROM were compared. RESULTS A total of 133 patients included 85 patients with GD cohort. There were no significant differences in pre hoc demographics and perioperative characteristics between cohorts, as well as preoperative, 6-week, or final follow-up PROMs between cohorts. Both cohorts demonstrated significant improvement in all PROMs at 6 weeks and final follow-up (P ≤ 0.049, all). There were no significant intercohort differences demonstrated in minimum clinically important difference achievement rates, ∆PROM-6W, or ∆PROM-FF in any PROM. CONCLUSIONS Regardless of the symptom duration before MIS-TLIF for DSpond, patients demonstrate significant improvement in physical function, pain, disability, and mental health. Patients with a GD of preoperative symptoms did not report inferior scores in any PROM domain. Patients with a GD of preoperative symptoms did not suffer inferior rates of clinically meaningful improvement after surgical intervention. These findings should be considered when counseling patients before surgical intervention for DSpond.

Does Preoperative Back Pain Impact Patient-reported Outcomes in Patients Undergoing Minimally Invasive Transforaminal Lumbar Interbody Fusion for Isthmic Spondylolisthesis? Clin Spine Surg 2024:01933606-990000000-00250. [PMID: 38178316 DOI: 10.1097/bsd.0000000000001568] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2023] [Accepted: 11/29/2023] [Indexed: 01/06/2024]
Abstract
STUDY DESIGN Retrospective review. OBJECTIVE To determine postoperative clinical outcomes in patients undergoing minimally invasive (MIS) transforaminal lumbar interbody fusion (TLIF) for isthmic spondylolisthesis (IS). BACKGROUND Few studies have examined the postoperative clinical trajectory in patients undergoing MIS-TLIF specifically for IS. METHODS Patients were separated into two cohorts based on the previously defined Visual Analog Scale (VAS) back pain (BP) for severe pain: VAS-BP <7 and VAS-BP ≥7. Patient-reported outcome measures (PROMs) of Patient-Reported Outcomes Measurement Information System-physical function (PF), 12-item Short Form (SF-12) Physical/Mental Component Score, Patient Health Questionnaire-9, VAS-BP, VAS leg pain, and Oswestry Disability Index were collected preoperatively and up to 2-year postoperatively. Minimum clinically important difference (MCID) was calculated through previously defined thresholds. RESULTS A total of 160 patients were recorded, with 58 patients in the VAS-BP <7 cohort. The VAS-BP <7 cohort demonstrated significant improvement in all PROMs at one or more postoperative time points. The VAS-BP ≥7 demonstrated significant improvement at 3 or more postoperative time points in all PROMs except for SF-12 Mental Component Score. The VAS-BP <7 cohort reported significantly superior preoperative and postoperative PROMs in all domains, except for SF-12 Physical Component Score. The VAS-BP ≥7 cohort had higher MCID achievement rates at one or more time points in multiple PROMs. CONCLUSION Patients undergoing MIS-TLIF for IS demonstrated significant postoperative improvement in PF, mental function, pain, and disability outcomes independent of preoperative severity of BP. Patients with lower preoperative BP demonstrated superior outcomes in PF, mental function, pain, and disability. However, patients with greater preoperative BP achieved higher rates of MCID in mental function, BP, and disability outcomes. Patients with greater severity of preoperative BP undergoing MIS-TLIF for IS may experience greater rates of clinically relevant improvement in mental function, BP, and disability outcomes.

Antibiotic use in spine surgery: A narrative review based in principles of antibiotic stewardship. NORTH AMERICAN SPINE SOCIETY JOURNAL 2023; 16:100278. [PMID: 37965567 PMCID: PMC10641566 DOI: 10.1016/j.xnsj.2023.100278] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Revised: 08/22/2023] [Accepted: 09/09/2023] [Indexed: 11/16/2023]
Abstract
Background A growing emphasis on antibiotic stewardship has led to extensive literature regarding antibiotic use in spine surgery for surgical prophylaxis and the treatment of spinal infections. Purpose This article aims to review principles of antibiotic stewardship, evidence-based guidelines for surgical prophylaxis and ways to optimize antibiotics use in the treatment of spinal infections. Methods A narrative review of several society guidelines and spine surgery literature was conducted. Results Antibiotic stewardship in spine surgery requires multidisciplinary investment and consistent evaluation of antibiotic use for drug selection, dose, duration, drug-route, and de-escalation. Developing effective surgical prophylaxis regimens is a key strategy in reducing the burden of antibiotic resistance. For treatment of primary spinal infection, the diagnostic work-up is vital in tailoring effective antibiotic therapy. The future of antibiotics in spine surgery will be highly influenced by improving surgical technique and evidence regarding the role of bacteria in the pathogenesis of degenerative spinal pathology. Conclusions Incorporating evidence-based guidelines into regular practice will serve to limit the development of resistance while preventing morbidity from spinal infection. Further research should be conducted to provide more evidence for surgical site infection prevention and treatment of spinal infections.

Effect of baseline veterans RAND-12 physical composite score on postoperative patient-reported outcome measures following lateral lumbar interbody fusion. Acta Neurochir (Wien) 2023; 165:3531-3537. [PMID: 37688649 DOI: 10.1007/s00701-023-05763-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2023] [Accepted: 08/07/2023] [Indexed: 09/11/2023]
Abstract
PURPOSE To determine the prognostic value of preoperative Veterans RAND-12 (VR-12) Physical Composite Score (PCS) scores on postoperative clinical outcomes in patients undergoing lateral lumbar interbody fusion (LLIF). METHODS LLIF patients were separated into 2 cohorts based on preoperative VR-12 PCS scores: VR-12 PCS < 30 (lesser physical function) and VR-12 PCS ≥ 30 (greater physical function). Patient-reported outcome measures (PROMs) of VR-12 PCS, VR-12 Mental Composite Score (MCS), Short Form-12 (SF-12) PCS, SF-12 MCS, Patient-Reported Outcomes Measurement Information System Physical Function (PROMIS-PF), Patient Health Questionnaire-9 (PHQ-9), Visual Analog Scale (VAS) Back Pain (VAS-BP), VAS Leg Pain (VAS-LP), and Oswestry Disability Index (ODI) were collected at preoperative and up to 2-year postoperative time points. Mean postoperative follow-up time was 16.69 ± 8.53 months. Minimum clinically important difference (MCID) achievement was determined by comparing ∆PROM to previously established thresholds. RESULTS Seventy-eight patients were included, with 38 patients with lesser preoperative physical function scores. Patients with lesser physical function reported significantly inferior preoperative PROM scores in all domains, except for SF-12 MCS and VAS-LP. At the 6-week postoperative time point, patients with lesser physical function reported significantly inferior VR-12 PCS, VR-12 MCS, SF-12 PCS, PROMIS-PF, and PHQ-9. At the final postoperative time point, patients with lesser physical function reported significantly inferior VR-12 PCS, VR-12 MCS, PROMIS-PF, PHQ-9, and ODI. Magnitude of 6-week postoperative improvement was significantly higher in the lesser physical function cohort for VR-12 PCS. CONCLUSION Patients undergoing LLIF with worse baseline VR-12 PCS scores reported inferior postoperative physical function, mental health, and disability outcomes. At the final postoperative follow-up, magnitude of postoperative improvement and MCID achievement did not significantly differ. Baseline VR-12 PCS scores may indicate inferior postoperative clinical outcomes in physical function, mental health, and disability in patients undergoing LLIF; however, baseline VR-12 PCS does not limit the magnitude of postoperative improvement.

Poor patient-reported mental health correlates with inferior patient-reported outcome measures following cervical disc replacement. Acta Neurochir (Wien) 2023; 165:3511-3519. [PMID: 37704886 DOI: 10.1007/s00701-023-05774-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Accepted: 08/18/2023] [Indexed: 09/15/2023]
Abstract
PURPOSE This study aims to assess the correlation between the patient-reported mental health and the self-reported outcome measures (PROMs) physical function, pain, and disability at different time points following disc replacement (CDR). METHODS A single-surgeon registry was searched for patients who had undergone CDR, excluding those with indication for infection, cancer, or trauma. One hundred fifty-one patients were included. PROMs were collected preoperatively as well as 6 weeks, 3 months, 6 months, and 1 year postoperatively. Mental health measures evaluated included 12-Item Short Form (SF-12), Mental Component Score (MCS), and Patient Health Questionnaire-9 (PHQ-9) which were individually assessed via Pearson's correlation tests in relation to Patient-Reported Outcome Measurement Information System Physical Function (PROMIS-PF), SF-12 Physical Component Score (PCS), visual analog scale (VAS) neck and arm pain, and Neck Disability Index (NDI). RESULTS SF-12 MCS positively correlated with PROMIS-PF (range: r = 0.369-0.614) and SF-12 PCS (range: r = 0.208-0.585) with significance found at two or more time points for each (p ≤ 0.009, all). SF-12 MCS negatively correlated with VAS neck (range: r = - 0.259 to - 0.464), VAS arm (range: r = - 0.281 to - 0.567), and NDI (range: r = - 0.474 to - 831) with significance found at three or more time points (p ≤ 0.028, all). PHQ-9 significantly negatively correlated with PROMIS-PF (range: r = - 0.457 to - 0.732) and SF-12 PCS (range: r = - 0.332 to - 0.629) at all time points (p ≤ 0.013, all). PHQ-9 positively correlated with VAS neck (range: r = 0.351-0.711), VAS arm (range: r = 0.239-0.572), and NDI (range: r = 0.602-0.837) at four or more periods (p ≤ 0.032, all). CONCLUSION Patients undergoing CDR who reported lower mental health scores via either SF-12 MCS or PHQ-9 were associated with increased perception of pain and disability. Disability level correlated with mental health at all time periods. Patients with optimized mental health may report higher outcome scores following CDR.

Abstract
PURPOSE We aim to examine the preoperative factors associated with increased postoperative length of stay in patients undergoing LLIF in the hospital setting. METHODS Patient demographics, perioperative characteristics, and patient-reported outcome measures (PROMs) were collected from a single-surgeon database. Patients undergoing LLIF in the hospital setting were separated into postoperative LOS <48 h (H) and LOS ≥ 48H. Univariate analysis for preoperative characteristics was utilized to determine covariates for multivariable logistic regression. Multivariable logistic regression was then utilized to determine significant predictors of extended postoperative length of stay. Secondary univariate analysis of inpatient complications, operative, and postoperative characteristics were calculated to determine postoperative factors associated with prolonged hospitalization. RESULTS Two-hundred and forty patients were identified with 115 patients' LOS ≥ 48H. Univariate analysis identified age/Charlson Comorbidity Index (CCI) score/gender/insurance type/number of contiguous fused levels/preoperative PROMs of Visual Analog Scale (VAS) back/VAS leg/Patient-Reported Outcomes Measurement Information System (PROMIS-PF)/Oswestry Disability Index (ODI)/degenerative spondylolisthesis diagnoses/foraminal stenosis/central stenosis for multivariable logistic regression. Multivariable logistic regression calculated significant positive predictors of LOS ≥ 48H to be age/3-level fusion/preoperative ODI scores. Negative predictors of LOS ≥ 48H were the diagnosis of foraminal stenosis/preoperative PROMIS-PF/male gender. The secondary analysis determined that patients with longer operative time/estimated blood loss/transfusion/postoperative day 0 and 1 pain and narcotic consumption/complications of altered mental status/postoperative anemia/fever/ileus/urinary retention were associated with prolonged hospitalization. CONCLUSION Older patients undergoing LLIF with greater preoperative disability and 3-level fusion were more likely to require prolonged hospitalization. Male patients with higher preoperative physical function and who were diagnosed with foraminal stenosis were less likely to require prolonged hospitalization.

Abstract
OBJECTIVE The objective of this study is to examine factors associated with delayed time to achieve minimum clinically important difference (MCID) in patients undergoing lumbar decompression (LD) for the Patient-Reported Outcomes (PROs) of Oswestry Disability Index (ODI), Visual Analog Scale (VAS) back, and VAS leg pain. METHODS Patients undergoing LD with preoperative and postoperative ODI, VAS back, and VAS leg scores were retrospectively reviewed from April 2016 to January 2021. MCID values from previously established studies were utilized to determine MCID achievement. Kaplan-Meier survival analysis determined the time to achieve MCID. Hazard ratios from multivariable Cox regression were utilized to determine the preoperative factors predictive of MCID achievement. RESULTS Three-hundred and forty-three patients were identified undergoing LD. Overall MCID achievement rates were 67.4% for ODI, 67.1% for VAS back, and 65.0% for VAS leg. The mean time in weeks for MCID achievement was 22.52 ± 30.48 for ODI, 18.90 ± 27.43 for VAS back, and 20.96 ± 29.81 for VAS leg. Multivariable Cox regression revealed active smoker status, preoperative Patient-Reported Outcomes Measurement Information System Physical Function (PROMIS-PF), ODI, VAS Back, and VAS Leg (HR 1.03-2.14) as predictors of early MCID achievement, whereas an American Society of Anesthesiologist (ASA) classification of 2, Black ethnicity, workers' compensation, private insurance, and diagnosis of foraminal stenosis were predictors of late MCID achievement (HR 0.34-0.58). CONCLUSION Most patients undergoing LD achieved MCID within 6 months of surgery. Significant factors for early MCID achievement were active smoking status and baseline PROs. Significant factors for late MCID achievement were ASA = 2, Black ethnicity, type of insurance, and foraminal stenosis diagnosis. These factors may be considered by surgeons in setting patient expectations.

Differences in Time to Achieve Minimum Clinically Important Difference Between Patients Undergoing Anterior Cervical Discectomy and Fusion and Cervical Disc Replacement. World Neurosurg 2023; 176:e337-e344. [PMID: 37230245 DOI: 10.1016/j.wneu.2023.05.059] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2023] [Revised: 05/15/2023] [Accepted: 05/16/2023] [Indexed: 05/27/2023]
Abstract
OBJECTIVE To compare patients undergoing anterior cervical discectomy and fusion (ACDF) versus cervical disc replacement (CDR) for time to minimum clinically important difference (MCID) achievement and predictors of delayed MCID achievement for the patient-reported outcomes (PROs), Patient-Reported Outcomes Measurement Information System Physical Function, Neck Disability Index, Visual Analog Scale (VAS) neck, and VAS arm. METHODS PROs of patients undergoing ACDF or CDR were collected preoperatively and postoperatively at 6-week/12-week/6-month/1-year/2-year periods. MCID achievement was calculated through comparison of changes in Patient-Reported Outcomes Measurement to previously established values in literature. Time to MCID achievement and predictors for delayed MCID achievement were determined through Kaplan-Meier survival analysis and multivariable Cox regression, respectively. RESULTS One hundred ninety-seven patients were identified, with 118 and 79 undergoing ACDF and CDR, respectively. Kaplan-Meier survival analysis demonstrated faster time to achieve MCID for CDR patients in Patient-Reported Outcomes Measurement Information System Physical Function (P = 0.006). Early predictors of MCID achievement through Cox regression were CDR procedure, Asian ethnicity, elevated preoperative PROs of VAS neck and VAS arm (hazard ratio, 1.16-7.28). Workers' compensation was a late predictor of MCID achievement (hazard ratio, 0.15). CONCLUSIONS Most patients achieved MCID in physical function, disability, and back pain outcomes within 2 years of surgery. Patients undergoing CDR achieved MCID faster in physical function. Early predictors of MCID achievement were CDR procedure, Asian ethnicity, and elevated preoperative PROs of pain outcomes. Workers' compensation was a late predictor. These findings may be helpful in managing patient expectations.

[PMID: 37564627 PMCID: PMC10411241 DOI: 10.1055/s-0042-1757767] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Accepted: 09/05/2022] [Indexed: 11/11/2022]
Abstract
Background It is difficult to evaluate the results of surgical techniques as there is inherent variability between surgeons in regard to experience, skill level, and knowledge. Tang suggested a classification system in 2009 in an attempt to standardize surgeon level of expertise, with categories ranging from nonspecialist (Level I) to expert (Level V). This epidemiological analysis of all articles citing Tang's original paper examines if a surgeon's self-reported level of expertise correlates with outcomes and evaluates whether the current definition of Tang level is sufficient to account for expertise bias. Methods In May 2021, all articles citing Tang level of expertise were identified ( N = 222). Articles were included if they described a novel technique and provided author(s)' levels ( n = 205). Statistical analysis was conducted, and p -values less than 0.05 were considered significant. Results The most common specialties reporting Tang level of expertise were orthopaedic surgery (82.9%) and plastic surgery (15.5%). The most common subspecialty was hand surgery. 2020 was the year with the most studies reporting level of expertise (31.7%), followed by 2021 (20.0%) and 2019 (17.1%). The majority of studies (80.5%) reported positive results with their technique, and of these, 63.3% were statistically significant. Level of expertise was not significantly associated with a doctoral degree, type of residency completed, fellowship completion, hand fellowship, author sex, study type, or result significance. Discussion The current Tang classification is both underreported and incomplete in its present state. To account for expertise bias, we recommend all authors report Tang level when describing surgical techniques. Studies with multiple authors should explicitly state the level of each author, as well as a weighted average accounting for the total contribution of each individual.

Postoperative clinical outcomes in patients undergoing MIS-TLIF versus LLIF for adjacent segment disease. Acta Neurochir (Wien) 2023; 165:1907-1914. [PMID: 37261504 DOI: 10.1007/s00701-023-05629-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Accepted: 04/29/2023] [Indexed: 06/02/2023]
Abstract
PURPOSE Few studies examine the clinical outcomes in patients undergoing minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) versus lateral lumbar interbody fusion (LLIF) for adjacent segment disease (ASD). We aim to compare the postoperative clinical trajectory through patient-reported outcome measures (PROMs) and minimum clinically important difference (MCID) in patients undergoing MIS-TLIF versus LLIF for ASD. METHODS Patients were stratified into two cohorts based on surgical technique for ASD: MIS-TLIF versus LLIF. PROMs of 12-Item Short Form Physical Component Score (SF-12 PCS), visual analog scale (VAS) back, VAS leg, and Oswestry Disability Index (ODI) were collected at preoperative and postoperative 6-week/12-week/6-month/1-year time points. MCID attainment was calculated through comparison to established thresholds. Cohorts were compared through nonparametric inferential statistics. RESULTS Fifty-four patients were identified, with 22 patients undergoing MIS-TLIF after propensity score matching. Patients undergoing MIS-TLIF for ASD demonstrated significant postoperative improvement up to 1-year VAS back, up to 1-year VAS leg, and 6-month through 1-year ODI (p ≤ 0.035, all). Patients undergoing LLIF demonstrated significant postoperative improvement in 6-month SF-12 PCS, 6-month through 1-year VAS back, 12-week through 6-month VAS leg, and 6-month to 1-year ODI (p ≤ 0.035, all). No significant differences were calculated between surgical techniques for PROMs or MCID achievement rates. CONCLUSION Patients undergoing either MIS-TLIF or LLIF for adjacent segment disease demonstrated significant postoperative improvement in pain and disability outcomes. Additionally, patients undergoing LLIF reported significant improvement in physical function. Both MIS-TLIF and LLIF are effective for the treatment of adjacent segment disease.

Depressed patients with greater symptom duration before MIS-TLIF do not report inferior outcomes. Acta Neurochir (Wien) 2023:10.1007/s00701-023-05593-8. [PMID: 37119321 DOI: 10.1007/s00701-023-05593-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Accepted: 04/10/2023] [Indexed: 05/01/2023]
Abstract
PURPOSE Patients with preoperative depressive symptoms may demonstrate inferior patient-reported outcomes (PROs). The effect of preoperative symptom duration (SD) on PROs in this population has not been well-studied. We aim to assess the influence of preoperative SD on PROs in patients with low mental health scores prior to minimally invasive transforaminal interbody fusion (MIS-TLIF). METHODS Patients who had undergone elective, primary MIS-TLIF with preoperative SF-12 MCS score below 45.6, a previously established threshold for depression, were selected. Patients were divided into matched lesser duration (LD; SD<365 days) and greater duration (GD; SD≥365 days) cohorts. PROs were collected preoperatively and at 6-week/12-week/6-month/1-year postoperative periods. PROs included PROMIS-PF/ODI/VAS back/VAS leg/SF-12 MCS. PROs were compared within and between groups. Rates of achievement of minimal clinically important difference (MCID) were compared between groups. RESULTS One hundred twenty-two patients were included after matching cohorts. Patients in the LD cohort demonstrated improvement in PROMIS-PF at 12-weeks/6-month/1-year, and ODI/VAS back/VAS leg/SF-12 MCS at all postoperative periods (p≤0.024, all). Patients in the GD cohort demonstrated improvement in PROMIS-PF at 12-weeks/6-month/1-year, and ODI/VAS back/VAS leg/SF-12 MCS at all postoperative periods (p≤0.013, all). There were no differences in PROs or MCID achievement between cohorts at any period. CONCLUSION Patients with preoperative depressive symptoms undergoing MIS-TLIF, regardless of duration of preoperative symptoms, demonstrated improvements in physical function, disability, pain, and mental health domains. Patients with greater duration of preoperative symptoms did not report inferior outcomes at any period. Rates of clinically important improvements in all domains were favorable and similar between cohorts.

Understanding the Impact of Early Depressive Burden on Patient Perceptions of Outcomes Following Cervical Disc Replacement. World Neurosurg 2023:S1878-8750(23)00575-2. [PMID: 37120140 DOI: 10.1016/j.wneu.2023.04.090] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Revised: 04/19/2023] [Accepted: 04/20/2023] [Indexed: 05/01/2023]
Abstract
OBJECTIVE To evaluate the effect of early depressive burden on PROMs in the setting of cervical disc replacement (CDR). METHODS Patients who had undergone primary elective CDR with recorded preoperative and 6-week 9-item PHQ-9 scores were identified. Early depressive burden was calculated via addition of the preoperative and 6-week PHQ-9 scores. Patients were divided into two cohorts, those with summative PHQ-9 scores beneath one-half standard deviation less than the mean (Lesser Burden; LB) and those with summative PHQ-9 scores above one-half standard deviation greater than the mean (Greater Burden; GB). Magnitude of improvement in PROMs (ΔPROM) were compared within and between cohorts at 6-weeks (ΔPROM-6W) and final follow-up (ΔPROM-FF). PROMs evaluated included PROMIS-PF/NDI/VAS-Neck (VAS-N)/VAS-Arm (VAS-A)/PHQ-9. RESULTS Fifty-five patients were included with 34 in the LB cohort. The LB cohort demonstrated improvements from the preoperative baseline in 6-week PROMIS-PF/NDI/VAS-N/VAS-A (p≤0.012, all). The GB cohort demonstrated improvements from the preoperative baseline in 6-week NDI/VAS-N/VAS-A/PHQ-9 (p≤0.038, all). The GB cohort demonstrated greater ΔPROM-6W and ΔPROM-FF in PHQ-9 (p≤0.047, both). The LB cohort demonstrated a greater ΔPROM-FF in PROMIS-PF (p=0.023). CONCLUSION Patients with a greater depressive burden were more likely to experience greater magnitudes of improvements in PHQ-9 at both 6-week and final follow-up and experience clinically meaningful improvement in depressive symptoms. Patients with a lesser depressive burden were more likely to experience a greater magnitude of improvement in PROMIS-PF at final follow-up and experience clinically meaningful improvement in physical function.

Perioperative Predictors in Patients Undergoing Lateral Lumbar Interbody Fusion for Minimum Clinically Important Difference Achievement. World Neurosurg 2023:S1878-8750(23)00527-2. [PMID: 37080454 DOI: 10.1016/j.wneu.2023.04.042] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Revised: 04/10/2023] [Accepted: 04/11/2023] [Indexed: 04/22/2023]
Abstract
OBJECTIVE To identify perioperative predictors of minimum clinically important difference (MCID) for patients undergoing lateral lumbar interbody fusion (LLIF) for the patient-reported outcome measures (PROMs) of Patient-Reported Outcomes Measurement Information System Physical Function (PROMIS-PF), Visual Analog Scale (VAS) Back, VAS Leg, Oswestry Disability Index (ODI), and Patient Health Questionnaire-9 (PHQ-9). METHODS Patients undergoing LLIF were identified through retrospective review of a single-surgeon database. Overall MCID achievement was determined as the number of unique patients achieving ΔPROM thresholds of PROMIS-PF=4.5, VAS Back=2.1, VAS Leg=2.8, ODI=14.9, and PHQ-9=3.0 over a 2-year postoperative time period. Univariate and multivariable logistic regression were utilized to determine perioperative predictors for MCID achievement. RESULTS Two-hundred and ninety patients were identified. For PROMIS-PF MCID achievement, increased preoperative PROMIS-PF and POD 1 VAS pain were significant negative predictors. For VAS Back, primary fusion with revision decompression was a negative predictor, while increased preoperative VAS Back was a positive predictor of MCID achievement. For VAS Leg, increased preoperative VAS Leg was a positive predictor. For ODI, increased POD 0 VAS pain was a negative predictor, while increased preoperative ODI was a positive predictor. For PHQ-9, increased preoperative PHQ-9 was a positive predictor. CONCLUSION In patients undergoing LLIF, perioperative predictors for MCID achievement were highly dependent on PROM. Preoperative PROM was the most consistent perioperative predictor for achieving MCID. Elevated acute postoperative pain and primary fusion after failed index decompression were significant predictors of failing to achieve MCID. Surgeons may use these findings in prognostication and management of postoperative expectations.

Abstract
OBJECTIVE To assess the potential effect of preoperative symptom duration on PROs in WC patients undergoing MIS-TLIF. METHODS WC patients who had undergone primary, elective MIS-TLIF with recorded duration of symptoms (DOS) data were included. Two cohorts were generated: Lesser Duration (LD; DOS<1 year) and Prolonged Duration (PD; DOS>1 year). PROs were collected preoperatively and at several periods up to 1-year postoperatively. PROs were compared within and between cohorts. Achievement rates of MCID were compared between cohorts. RESULTS 145 patients were included, with 76 in the PD cohort. The LD cohort demonstrated improvement in PROMIS-PF at 6-months/1-year, ODI at 12-weeks/6-months, VAS back at 6-weeks/12-weeks/6-months, and VAS leg at all postoperative periods (p≤0.015, all). The PD cohort demonstrated improvement in PROMIS-PF at 12-weeks/6-months, ODI at 6-weeks/12-weeks/6-months, and VAS back and VAS leg at all postoperative periods (p≤0.007, all). Between cohorts, all preoperative PROs were superior in the LD cohort (p<0.001, all). The LD cohort reported better PROMIS-PF at 6-months/1-year and ODI at 1-year (p≤0.037, all). The PD cohort was more likely to achieve MCID in ODI at 6-weeks/12-weeks, VAS back at 6-weeks, and VAS leg at 6-weeks, 1-year and Overall (p≤0.036, all). CONCLUSION Independent of preoperative symptom duration, WC patients demonstrated improvements in physical function and pain following MIS-TLIF. Patients with greater symptom duration reported inferior function and pain preoperatively. Patients with longer duration of symptoms prior to intervention were more likely to demonstrate clinically significant improvements in disability and pain.

Establishing Minimum Clinically Important Difference Thresholds for Physical Function and Pain in Patients Undergoing Anterior Lumbar Interbody Fusion. World Neurosurg 2023:S1878-8750(23)00408-4. [PMID: 36972902 DOI: 10.1016/j.wneu.2023.03.087] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2023] [Revised: 03/20/2023] [Accepted: 03/21/2023] [Indexed: 03/29/2023]
Abstract
OBJECTIVE To establish minimum clinically important difference (MCID) in anterior lumbar interbody fusion (ALIF) for the physical function PROMs Patient-Reported Outcomes Measurement Information System Physical Function (PROMIS-PF), 12-Item Short Form (SF-12) Physical Component Score (PCS), and Veterans RAND-12 (VR-12) PCS and pain PROMs Visual Analog Scale (VAS) Back and VAS Leg through anchor- and distribution-based calculations. METHODS Patients undergoing ALIF with preoperative and 6-month Oswestry Disability Index (ODI) were included. Using ODI as the anchor, anchor-based calculation methods were the average change, minimum detectable change (MDC), and receiver operating characteristic (ROC) curve methods. Distribution-based methods were the standard error of measurement (SEM), receiver change index (RCI), effect size, and 0.5ΔSD. RESULTS 51 patients were identified. Anchor-based methods ranged from 2.9-11.5 for PROMIS-PF, 8.2-13.6 for SF-12 PCS, 7.8-16.8 for VR-12 PCS, 0.5-3.9 for VAS Back, and 1.0-3.4 for VAS Leg. AUC ranged from 0.59 (VAS Back) to 0.78 (VR-12 PCS). Distribution-based methods ranged from 1.0-4.2 for PROMIS-PF, 1.8-12.2 for SF-12 PCS, 1.9-6.2 for VR-12 PCS, 0.4-1.6 for VAS Back, and 0.5-1.7 for VAS Leg. CONCLUSION The MCID values greatly relied on the calculation method. The minimum detectable change method was selected as the most appropriate MCID calculation method. The MCID values that may be utilized for ALIF patients are 7.3 for PROMIS-PF, 8.2 for SF-12 PCS, 7.8 for VR-12 PCS, 3.2 for VAS Back, and 2.2 for VAS Leg.

Impact of body mass index on PROMIS outcomes following lumbar decompression. Acta Neurochir (Wien) 2023; 165:1427-1434. [PMID: 36892729 DOI: 10.1007/s00701-023-05534-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2023] [Accepted: 02/11/2023] [Indexed: 03/10/2023]
Abstract
BACKGROUND No studies have examined the impact of body mass index (BMI) on newer Patient-Reported Outcomes Measurement Information System (PROMIS) outcomes in patients undergoing lumbar decompression (LD). METHODS Patients undergoing LD with preoperative PROMIS measures were stratified into four cohorts: normal (18.5 ≤ BMI < 25 kg/m2), overweight (25 ≤ BMI < 30 kg/m2), obese I (30 ≤ BMI < 35 kg/m2), and obese II-III (BMI ≥ 35 kg/m2). Demographics, perioperative characteristics, and patient-reported outcomes (PROs) were obtained. PROs of PROMIS Physical Function (PROMIS-PF), PROMIS Anxiety (PROMIS-A), PROMIS Pain Interference (PROMIS-PI), PROMIS Sleep Disturbance (PROMIS-SD), Patient Health Questionnaire-9 (PHQ-9), Visual Analog Scale (VAS) Back Pain (VAS-BP), VAS Leg Pain (VAS-LP), and Oswestry Disability Index (ODI) were collected at preoperative and up to 2-year postoperative time points. Minimum clinically important difference (MCID) achievement was determined through comparison of previously established values. Comparison between cohorts were determined through inferential statistics. RESULTS A total of 473 patients were identified, with stratification of 125 patients in the normal cohort, 161 in the overweight cohort, 101 in the obese I cohort, and 87 in the obese II-III cohort. Mean postoperative follow-up time was 13.51 ± 8.72 months. Higher BMI patients had higher operative times, longer postoperative length of stay, and greater narcotic consumption (p ≤ 0.001, all). Patients with higher BMI (obese I, obese II-III) reported inferior preoperative PROMIS-PF, VAS-BP, and ODI scores (p ≤ 0.003, all). Postoperatively, obese I-III cohorts demonstrated inferior PROMIS-PF, PHQ-9, VAS-BP, and ODI scores at final follow-up (p ≤ 0.016, all). However, patients demonstrated similar postoperative changes and MCID achievement regardless of preoperative BMI. CONCLUSION Patients undergoing lumbar decompression demonstrated similar postoperative improvement in physical function, anxiety, pain interference, sleep disturbance, mental health, pain, and disability outcomes independent of preoperative BMI. However, obese patients reported worse physical function, mental health, back pain, and disability outcomes at final postoperative follow-up. Patients with greater BMI undergoing lumbar decompression demonstrate inferior postoperative clinical outcomes.

Does Symptom Duration Prior to ACDF for Disc Herniation Influence Patient-Reported Outcomes in a Workers' Compensation Population? World Neurosurg 2023; 173:e748-e754. [PMID: 36898631 DOI: 10.1016/j.wneu.2023.03.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2023] [Revised: 02/28/2023] [Accepted: 03/02/2023] [Indexed: 03/11/2023]
Abstract
OBJECTIVE To evaluate the influence of symptom duration (SD) prior to ACDF on patient-reported outcomes (PROs) in WC patients. METHODS A prospective registry was searched for WC patients who underwent ACDF for herniated disc(s). Two cohorts were formed: Lesser Duration (LD; SD<6 months) and Prolonged Duration (PD; SD≥6 months). PROs were collected preoperatively and at 6-weeks/12-weeks/6-months/1-year postoperatively. PROs were compared within and between groups. Rates of MCID were compared between groups. RESULTS 63 patients were included. The LD cohort reported improvement in PROMIS-PF/NDI/VAS neck at 12-weeks/6-months, and VAS arm at all periods (p≤0.036, all). The LD cohort reported improvement in NDI at 12-weeks/6-months and VAS arm at 6-weeks/12-weeks/6-months (p≤0.037, all). Between groups, the LD cohort demonstrated superior scores in PROMIS-PF at 6-weeks/12-weeks/6-months, NDI preoperatively and at 6-weeks/12-weeks/6-months, VAS neck at 12-weeks, and PHQ-9 at 6-months (p≤0.045, all). The LD group was more likely to achieve MCID in PROMIS-PF at 12-weeks (p=0.012). The PD group was more likely to achieve MCID in PHQ-9 at 6-months (p=0.023). CONCLUSION Despite length of symptom duration prior to ACDF in WC patients, patients demonstrated improvements in disability and arm pain. Patients with a lesser SD also demonstrated improvements in physical function and neck pain. Patients with a lesser SD demonstrated superior scores in physical function, pain, disability, and mental health and were more likely to achieve clinically significant improvement in physical function. Patients with a greater symptom duration SD were more likely to achieve clinically significant improvement in mental health.

Abstract
BACKGROUND Few studies have examined the influence of preoperative disability through the Oswestry Disability Index (ODI) on clinical outcomes in patients undergoing anterior lumbar interbody fusion (ALIF). METHODS Patients undergoing ALIF were separated into 2 groups based on ODI<41 (lower disability) versus ODI≥41% (higher disability). Patient-reported outcomes (PROs) were collected at preoperative and postoperative 6-week/12-week/6-month/1-year/2-year time points. Physical function PROs were Patient-Reported Outcomes Measurement Information System Physical Function and 12-item Short Form Physical Component Score. Mental function PROs were 12-item Short Form Mental Component Score and Patient Health Questionnaire-9. Pain PROs were visual analog scale back and visual analog scale leg. ODI was the disability PRO. RESULTS A total of 148 patients were identified, with 52 patients with lower disability. Higher disability patients demonstrated significant improvement in mental function (P ≤ 0.010, all). Lower disability patients demonstrated superior postoperative PROs in physical function, mental function, back pain, and disability outcomes (P ≤ 0.034, all). Minimum clinically important difference achievement rates for lower disability patients were higher for back pain and lower for mental function and disability outcomes (P ≤ 0.041, all). CONCLUSIONS Independent of preoperative disability, patients undergoing ALIF reported significant postoperative improvement in physical function, pain, and disability outcomes. Patients with lower preoperative disability continued to report superior PROs in mental function, back pain, and disability postoperatively. Minimum clinically important difference achievement rates for lower disability patients were higher for back pain and lower in mental function and disability outcomes. Patients undergoing ALIF with higher preoperative disability may experience greater clinically meaningful improvement in mental function and disability.

The Impact of the Florida Law HB21 on Opioid Prescribing Patterns After Spine Surgery. NORTH AMERICAN SPINE SOCIETY JOURNAL (NASSJ) 2023; 14:100202. [PMID: 36970062 PMCID: PMC10034149 DOI: 10.1016/j.xnsj.2023.100202] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Revised: 02/05/2023] [Accepted: 02/06/2023] [Indexed: 02/18/2023]
Abstract
Background The opioid epidemic represents a major public health issue in the United States and has led to significant morbidity and mortality. On July 1 2018, Florida implemented state-law House Bill 21 (HB21), limiting opioid prescriptions to a 3-day supply for acute pain or 7 days if an exception is documented. The purpose of this study is to evaluate the effects of HB21 on opioid prescribing patterns after spine surgery. Methods Patients 18 years and older who underwent spine surgery between January 2017 and January 2021 were eligible for inclusion. Information including demographics, pills, days, and morphine milligram equivalents (MMEs) was obtained via retrospective chart review using the Florida Prescription Drug Monitoring Program and Epic Chart Review. Student's t tests and Fisher's exact tests were used for comparison of continuous variables. Multiple logistic regression was utilized to determine which variables were associated with postoperative opioid prescriptions. p<.05 was considered significant. Results We reviewed 114 patients who underwent spine surgery from January 2017 to July 2018 and 264 patients from July 2018 to January 21. There were no significant differences between the groups in age, sex, ethnicity, body mass index, number of levels fused, or preoperative opioid use. The average number of MMEs, pills prescribed and days in the first postoperative prescription decreased significantly after HB21. Multiple logistic regression revealed that the variable most predictive of MMEs and number of pills in the first postoperative prescription was postlaw status (p=.002, p=.50). Conclusions Florida law HB21 was successful in decreasing postoperative opioid prescriptions after spine surgery, however, the need for additional progress remains. Legislation should be combined with multimodal pain regimens, as well as patient and provider education in order to further decrease postoperative opioid requirements. Future studies should include a larger number of patients treated by multiple spine surgeons across multiple institutions in order to further evaluate the effects of HB21 on postoperative opioid prescriptions.

Impact of preoperative symptom duration in patients undergoing lateral lumbar interbody fusion. Acta Neurochir (Wien) 2023; 165:89-97. [PMID: 36564650 DOI: 10.1007/s00701-022-05436-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2022] [Accepted: 11/21/2022] [Indexed: 12/24/2022]
Abstract
BACKGROUND Few studies have examined the influence of preoperative symptom duration on clinical outcomes in patients undergoing lateral lumbar interbody fusion (LLIF) for degenerative conditions. METHODS Patients undergoing LLIF presenting with radiculopathy and/or neurogenic claudication were separated into two groups: preoperative symptom duration < 1-year (shorter duration) versus duration ≥ 1-year (longer duration). Patients undergoing surgery for trauma/malignancy/infection were excluded. Patient-reported outcome measures (PROMs) of Patient-Reported Outcomes Measurement Information System-Physical Function (PROMIS-PF), 12-Item Short Form Physical/Mental Component Score (SF-12 PCS/MCS), Patient Health Questionnaire-9 (PHQ-9), visual analog scale (VAS) back/leg, and Oswestry Disability Index (ODI) were collected at preoperative and postoperative time points. RESULTS Eighty-two total patients, with 34 shorter-duration patients, were identified after propensity score matching for demographics. Longer-duration patients had higher estimated blood loss. All patients reported significant improvement in physical function, mental function, pain, and disability in at least one postoperative time point, except for SF-12 MCS in the shorter duration cohort. The longer duration cohort had higher MCID achievement in 12-week VAS back. CONCLUSION Patients undergoing LLIF demonstrated significant postoperative improvement in physical function, mental function, pain, and disability outcomes independent of preoperative symptom duration. Both cohorts, when compared by preoperative symptom duration, demonstrated similar postoperative PROM scores. Patients with longer preoperative symptom duration had higher 12-week leg pain MCID achievement. These findings suggest that delayed time to surgery may not lead to inferior clinical outcomes in patients undergoing LLIF for degenerative conditions.

BACKGROUND In the Spring of 2020, residency programs across the country experienced rapid and drastic changes to their application process as a result of the coronavirus disease 2019 (COVID-19) pandemic. In response, residency programs shifted to virtual events and began harnessing social media to communicate with applicants.
AIM To analyze the changes in social media usage by orthopaedic surgery programs in response to the COVID-19 pandemic.
METHODS Based on the 2019 residency and fellowship electronic database, accredited US orthopaedic surgery programs were reviewed for social media presence on Instagram and Twitter. Approximately 47000 tweets from 2011-2021 were extracted through the Twitter application programming interface. We extracted: Total number of followers, accounts following, tweets, likes, date of account creation, hashtags, and mentions. Natural language processing was utilized for tweet sentiment analysis and classified as positive, neutral, or negative. Instagram data was collected and deemed current as of August 11, 2021. The account foundation date analysis was based on the date recognized as the start of the COVID-19 outbreak in the United States, before or after March 1, 2020.
RESULTS A total of 85 (42.3%) orthopaedic surgery residency program Twitter handles were identified. Thirty-five (41.2%) programs joined Twitter in the nine months after the 2020 covid outbreak. In 2020, there was a 126.6% increase in volume of tweets by orthopaedic surgery residency accounts as compared to 2019. The median number of followers was 474.5 (interquartile range 205.0-796.5). The account with the highest number of tweets was Hospital for Special Surgery (@HSpecialSurgery) with 13776 tweets followed by University of Virginia (@UVA_Ortho) with 5063 and Yale (@OrthoAtYale) with 899. Sentiment analysis before 2020 revealed 30.4% positive, 60.8% neutral, and 8.8% negative sentiments across tweets. Interestingly, the positive sentiment percentage increased in 2020 from 30.4% to 34.5%. Of the 201 ACGME-accredited orthopaedic residency programs on Fellowship and Residency Electronic Interactive Database, 115 (57.2%) participate on Instagram, with 101 (87.8%) identified as “resident”-managed vs 14 (12.2%) identified as “department”-managed. Over three quarters (77.4%) of Instagram accounts were created after March 1, 2020. The average number of followers per account was 1089.5 with an average of 58.9 total posts.
CONCLUSION Our study demonstrates a substantial growth of Instagram and Twitter presence by orthopaedic surgery residency programs during the COVID-19 pandemic. These data suggest that orthopaedic residency programs have utilized social media as a new way to communicate with applicants and showcase their programs in light of the challenges presented by the pandemic.

Expertise of Surgeons Publishing Novel Techniques in the Journal of Wrist Surgery. J Wrist Surg 2022; 11:35-40. [PMID: 35127262 PMCID: PMC8807097 DOI: 10.1055/s-0041-1731330] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/14/2021] [Accepted: 04/21/2021] [Indexed: 10/20/2022]
Abstract
Introduction Recent efforts to standardize reporting of surgeon experience in novel technique publications have recommended reporting of Tang level of expertise (LOE). Question/Purpose The aim of this study was to document trends in LOE reporting for novel technique articles published in the Journal of Wrist Surgery and evaluate whether author experience affects novel research outcomes. Methods A total of 261 articles published from 2018 to 2020 were reviewed. Articles describing novel surgical techniques were included and examined for Tang LOE. Author variables were collected online. Results Eight percent (21/261) of articles discussed novel surgical techniques and one reported LOE. Nearly half (47.6%) of articles did not conduct statistical analysis. Four (19.0%) reported insignificant statistical results and 7 (33.3%) reported significant findings. All significant statistical findings were positive. Number of prior related publications by the senior author did not affect new technique result significance ( p = 0.34). Discussion From 2018 to 2020, only one article documented LOE. Authors' variables, including number of prior related publications, were not correlated with significant results in their new publications. This may suggest that an author's established experience in a novel technique, quantified by prior publications on the topic, does not make one more likely to achieve significantly better or worse outcomes in their reviewed Journal of Wrist Surgery study. Conclusions Tang LOE is an important way for readers to classify expertise and should be reported, and potentially modified to better define contributing variables.

Abstract
Introduction. The sensitivity and specificity for magnetic resonance imaging (MRI) diagnosis of osteomyelitis is 90% and 80%, respectively; findings include bone marrow edema, T2-weighted image hyperintensity (HI-T2WI), T1-weighted image confluent signal(CS-T1WI), and cortical erosion (CE). The goal is to determine which risk factors and MRI findings are most predictive of osteomyelitis. Materials and Methods. After institutional review board approval, records of patients who underwent bone biopsy of the foot/ankle between 2015 and 2017 were reviewed. Diagnosis was determined histologically. Blinded MRI review identified indicators of osteomyelitis: HI-T2WI, CS-T1WI, ulcer depth, and CE. Bivariate and multivariate regression determined an association between osteomyelitis and radiographic indicators. Results. Of 59 subjects, 41 (69.5%) and 18 (30.5%) had pathologic evidence of osteomyelitis or were indeterminate. The sensitivity and specificity by radiologist diagnosis was 51.4% and 91.7%, respectively. Diabetes (relative risk [RR]=2.9, 95% CI = 1.0.8-7.77, P = .034), CS-T1WI (RR = 1.6, 95% CI = 1.23-2.20, P < .001), and CE (RR = 1.8, 95% CI = 1.34-2.28, P < .001) were risk factors on bivariate analysis. Ulcer depth demonstrated a trend toward statistical significance. Diabetes (RR = 2.4, 95% CI = 1.00-5.69, P = .049) and CE (RR = 1.7, 95% CI = 1.27-2.37, P < .001) were independent risk factors on multivariate analysis. Discussion. Diabetes and CS-T1WI are independent risk factors for pedal osteomyelitis. Patients with diabetes, CS-T1WI, and CE should be evaluated for osteomyelitis with recommendation for bone biopsy in appropriate clinical settings.Levels of Evidence: Level III Retrospective Comparative Study.

Abstract
CASE We report a case of a 68-year-old woman who developed left shoulder glenohumeral joint septic arthritis within 1 week of receiving the COVID-19 Pfizer-BioNTech vaccine. CONCLUSION Common vaccine complications include injection site pain, fever, chills, arthralgia, and hypersensitivity reactions. A less common and more serious complication of septic arthritis has been reported and requires invasive treatment of surgical irrigation and debridement, and culture-specific parenteral antibiotic therapy. The current report highlights the clinical presentation and significant potential for serious complication with the improper technique. We urge vaccine administrators to practice caution and aseptic technique when vaccinating patients to reduce the risk of complication and morbidity.

Abstract
BACKGROUND Hallux valgus is one of the most common surgically corrected forefoot deformities. Compared to open procedures, minimally invasive (MIS) treatment of hallux valgus has resulted in decreased operative time, reduced complication rates, and greater patient satisfaction. Historically, distal chevron osteotomies are the standard for moderate hallux valgus correction. To our knowledge, no studies have evaluated biomechanical strength of transverse and chevron distal first metatarsal osteotomy (DMO) constructs. The purpose of this study was to evaluate the biomechanical strength of these techniques. METHODS Eighteen cadaveric specimens (9 matched pairs) were randomized to transverse or chevron DMO. Each technique was performed by a separate fellowship-trained orthopedic foot and ankle surgeon. Radiographic images were analyzed. Biomechanical testing was performed using Instron Mechanical System. Ultimate load to failure, yield load, and stiffness were assessed. A 10-N preload was applied to the sesamoid bones for stability. A coaxial compression rate (10 mm/min) was applied until failure was observed. Mean and standard deviations were compared. All cadaveric specimens were male. RESULTS There was no significant difference in percent metadiaphyseal shift between osteotomies (P = .453). The most common mode of failure was fracture at screw insertion site (55.6%), followed by failure at osteotomy site (44.4%). A trend toward increased ultimate load to failure (P = .480), yield load (P = .054), and stiffness (P = .438) among transverse compared to chevron osteotomy was observed, but this difference was not statistically significant. CONCLUSION Biomechanical testing demonstrated no significant difference in ultimate load, yield load, and stiffness between MIS transverse and chevron osteotomy constructs; a trend toward increased strength in the transverse osteotomy cohort was observed. Chevron osteotomies may result in early failure by relative ease of cutout through cancellous bone compared to transverse osteotomies in which failure requires cortical cutout. CLINICAL RELEVANCE Use of MIS techniques for hallux valgus correction is gaining clinical traction. Although various clinical studies have evaluated outcomes of these MIS techniques, biomechanical studies have been minimal. Specifically, the potential biomechanical benefits of various MIS hallux valgus osteotomy techniques have not been delineated to date. The content of this manuscript is quite timely, given the rise in use of these MIS techniques.

The influence of cognitive behavioral therapy on lumbar spine surgery outcomes: a systematic review and meta-analysis. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2021; 30:1365-1379. [PMID: 33566172 DOI: 10.1007/s00586-021-06747-x] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/04/2020] [Revised: 12/14/2020] [Accepted: 01/20/2021] [Indexed: 12/19/2022]
Abstract
PURPOSE As more patients undergo lumbar spine surgery, novel interventions may improve physical and mental health outcomes. Few studies summarize the benefit of cognitive behavioral therapy (CBT) among lumbar spine surgery patients. This study collects randomized control trial data to investigate the influence of CBT on patient reported outcomes among lumbar spine surgery patients. METHODS Our study used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and a medical library expert assisted in searching PubMed/MEDLINE, Scopus, CINAHL, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, PsycINFO, and Google Scholar. We calculated standardized mean differences (SMD) to evaluate the effect size of CBT versus control groups with a sensitivity analysis. RESULTS Our meta-analysis included seven studies with a total of 531 patients. The majority of included studies evaluated lumbar fusion, with preoperative CBT performed by physiotherapists. The largest effects were observed for overall quality of life (SMD = 0.55 [95% CI 0.05, 1.05], p < 0.001, I2 = 86.7%) and psychological outcomes (SMD = 0.61 [95% CI 0.28, 0.94], p < 0.001, I2 = 89.7%) though disability and pain outcomes also favored CBT intervention. Included studies demonstrated low overall bias but large heterogeneity. Sensitivity analysis demonstrated negligible study design differences and revealed moderators including CBT session frequency and final follow-up duration (p < 0.001). CONCLUSION Compared to usual care or alternative therapy control arms, CBT delivered the most improvement with overall quality of life and psychological outcomes. Among appropriately selected patients, CBT could improve perioperative disability, pain, quality of life, and psychological health following lumbar spine surgery.

Abstract
BACKGROUND Preoperative depression is associated with increased perioperative pain, worse physical function, reduced quality of life, and inferior outcomes. Few studies have evaluated depressive symptoms between genders for individuals undergoing minimally invasive transforaminal lumbar interbody fusion (MIS TLIF). The purpose of this investigation was to assess the severity of Patient Health Questionnaire-9 (PHQ-9) scores among patients with depressive symptoms before and after single-level MIS TLIF. METHODS A prospective surgical registry was retrospectively reviewed for spine surgeries between March 2016 and December 2018. We included patients with at least mild depressive symptoms (PHQ-9 scores ≥ 5) who underwent primary, single-level MIS TLIF and compared genders using χ2 tests and t tests. Genders were stratified by depressive symptom severity: mild (5-9), moderate (10-14), and moderately severe (≥15) and then analyzed at preoperative and postoperative intervals: 6 weeks, 12 weeks, 6 months, and 1 year. Finally, PHQ-9 scores were validated with a Pearson correlation test against the 12-item Short Form (SF-12) Mental Composite Score (MCS) and the Veterans RAND (VR-12) MCS. RESULTS Of 75 subjects, 44.0% were women and the mean age was 49.9 years. The preoperative distribution among PHQ-9 subgroups was 38.7%, 26.6%, and 34.7% for mild, moderate, and moderately severe depressive symptoms, respectively. Among PHQ-9 stratifications both genders demonstrated intermittent statistically significant improvements in PHQ-9 scores. The moderately severe PHQ-9 subgroup had improvement at all postoperative time points. The PHQ-9 scores demonstrated a strong correlation with the SF-12 MCS and VR-12 MCS at all postoperative evaluations. CONCLUSION At baseline and by the final 1-year follow-up there were no statistically significant PHQ-9 score differences between genders within any depressive symptom stratifications. Whereas some contend that men and women have substantial mental health differences, this study is aligned with growing evidence that demonstrates similar depressive symptoms between genders. LEVEL OF EVIDENCE 3. CLINICAL RELEVANCE Men and women may be at an equivalent risk for perioperative depressive symptoms.

Fluoroscopy time analysis of a prospective, multi-centre study comparing robotic- and fluoroscopic-guided placement of percutaneous pedicle screw instrumentation for short segment minimally invasive lumbar fusion surgery. Int J Med Robot 2020; 17:e2188. [PMID: 33217131 DOI: 10.1002/rcs.2188] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2020] [Revised: 09/20/2020] [Accepted: 10/16/2020] [Indexed: 12/13/2022]
Abstract
BACKGROUND As minimally invasive spine surgery becomes more widespread, concerns regarding radiation exposure to surgeons and patients alike have become a growing concern. Robotic guidance has been developed as a way to increase the accuracy of instrumentation while decreasing radiation burden. METHODS A retrospective analysis of a large, multi-centre, prospective study comparing robotic-guided (RG) to fluoroscopic-guided (FG) (Multi-centre, Partially Randomized, Controlled Trial of MIS Robotic vs. Freehand in Short Adult Degenerative Spinal Fusion Surgeries) was performed to evaluate for differences in radiation exposure between study groups. RESULTS RG was associated with 78.3% (p < 0.001) and 79.8% (p < 0.001) reduction in total and per screw fluoroscopy times, respectively, as compared to FG. RG was also associated with a 50.8% (p < 0.001) reduction in total operative fluoroscopy time. CONCLUSIONS RG was associated with significantly lower fluoroscopy times compared to FG. This suggests that utilization of robotic navigation systems may result in decreased operative radiation exposure, which is a growing concern for surgeons performing minimally invasive spine surgery.

Abstract
BACKGROUND Improvement in patient-reported outcomes after minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) is poorly defined. As such, the purpose of this study was to quantify improvements in Visual Analogue Scale back and leg pain, Oswestry Disability Index (ODI), and Short Form-12 (SF-12) Mental and Physical Composite scores following MIS-TLIF. METHODS A surgical registry of patients who underwent primary 1-level MIS-TLIF during 2014-2015 was reviewed. Comparisons of Visual Analogue Scale back and leg pain, ODI, and Short Form-12 Mental and Physical Composite scores were performed using paired t tests from preoperative to each postoperative time point. Analysis of variance was used to estimate the degree of improvement in back and leg pain over the first postoperative year. Subgroup analysis was performed for patients presenting with predominant back (pBP) or leg (pLP) pain. Multivariate linear regression was performed to compare patient-reported outcome scores by subgroup. RESULTS A total of 106 patients were identified. Visual Analogue Scale back and leg scores, and ODI improved from preoperative scores at all postoperative time points (P < .05 for each). Patients with pBP (n = 68) and patients with pLP (n = 38) reported reductions in both back and leg pain over the first postoperative year (P < .05 for each). In the pBP cohort, patients experienced significant reductions in ODI after the first 6 postoperative weeks (P < .05 for each). In the pLP cohort, patients experienced significant reductions in ODI throughout the first postoperative year (P < .05 for each). Patients with pLP and pBP experienced similar reductions in back pain, whereas patients with pLP experienced significantly greater reductions in leg pain at all postoperative time points (P < .05 for each). CONCLUSIONS The current study suggests patients experience significant improvements in back and leg pain following MIS-TLIF regardless of predominant symptom. CLINICAL RELEVANCE These results can assist surgeons when counseling their patients on the magnitude of symptom improvement they may experience following MIS-TLIF.

Abstract
The purpose of the study was to evaluate the trend in documentation of surgeon level of expertise among the Journal of Hand Surgery (American Volume) and the Journal of Hand Surgery (European Volume) publications. A review of Journal of Hand Surgery (American Volume) and Journal of Hand Surgery (European Volume) databases for level of expertise between January 2015 and October 2019 was performed. Of 1042 articles identified, all 115 (20%) reporting level of expertise were published in Journal of Hand Surgery (European Volume). Since 2015, there has been an increase in reported level of expertise in Journal of Hand Surgery (European Volume) (2015: 8 (7%); 2016: 15 (13%); 2017: 22 (19%); 2018: 28 (24%); 2019: 42 (37%)). In the same period, no publications have reported level of expertise in Journal of Hand Surgery (American Volume). Documenting level of expertise may provide readers with additional information for incorporation of novel techniques into their practices. It may identify procedures that require a baseline level of expertise for effective performance. Further evaluation of level of expertise criteria may improve the reliability of the numeric scale, while widespread adoption of this scale will allow future outcome analysis by level of expertise.

Abstract
In this review, we discuss the demonstrated value of vitamin D in bone maintenance, fracture resistance, spinal health, and spine surgery outcomes. Despite this, the effect of vitamin D levels in spine surgery has not been well described. Through this review of literature, several conclusions were drawn. First, despite the fact that a high number of spine surgery patients are vitamin D deficient, screening is not commonly performed. Second, adequate vitamin D levels will not be achieved in a majority of these patients without supplementation. Last, inadequate vitamin D levels may increase the risk of pseudarthrosis. Given these findings, we suggest that many patients undergoing spinal surgery could be treated with vitamin D supplementation prior to surgery without the need for confirmatory testing for vitamin D deficiency. This is a more cost-effective method than screening all patients. However, future randomized trials and cost-effectiveness analyses are needed to determine the ultimate effects of vitamin D supplementation on clinical morbidity and surgical outcomes.

Abstract
OBJECTIVE While the anterior lumbar interbody fusion (ALIF) procedure may be amenable to ambulatory surgery, it has been hypothesized that limitations such as the risk of postoperative ileus and vascular complications have hindered transition of this procedure to the outpatient setting. Identification of independent risk factors predisposing patients to inpatient stays of ≥ 24 hours after ALIF may facilitate better postsurgical outcomes, target modifiable risk factors, and assist in the development of screening tools to transition appropriate patients to the ambulatory surgery center (ASC) setting for this procedure. The purpose of this study was to identify the most relevant risk factors that predispose patients to ≥ 24-hour admission following ALIF. METHODS A prospectively maintained surgical registry was reviewed for patients undergoing single ALIF between May 2006 and December 2019. Demographics, preoperative diagnosis, perioperative variables, and postoperative complications were evaluated according to their relative risk (RR) elevation for an inpatient stay of ≥ 24 hours. A Poisson regression model was used to evaluate predictors of inpatient stays of ≥ 24 hours. Risk factors for inpatient admission of ≥ 24 hours were identified with a stepwise backward regression model. RESULTS A total of 111 patients underwent single-level ALIF (50.9% female and 52.6% male, ≤ 50 years old). Eleven (9.5%) patients were discharged in < 24 hours and 116 remained admitted for ≥ 24 hours. The average inpatient stay was > 2 days (53.7 hours). The most common postoperative complications were fever (body temperature ≥ 100.4°F; n = 4, 3.5%) and blood transfusions (n = 4, 3.5%). Bivariate analysis revealed a preoperative diagnosis of retrolisthesis or lateral listhesis to elevate the RR for an inpatient stay of ≥ 24 hours (RR 1.11, p = 0.001, both diagnoses). Stepwise multivariate analysis demonstrated significant predictors for inpatient stays of ≥ 24 hours to be an operation on L4-5, coexisting degenerative disc disease (DDD) with foraminal stenosis, and herniated nucleus pulposus (RR 1.11, 95% CI 1.03-1.20, p = 0.009, all covariates). CONCLUSIONS This study provides data regarding the incidence of demographic and perioperative characteristics and postoperative complications as they pertain to patients undergoing single-level ALIF. This preliminary investigation identified the most relevant risk factors to be considered before appropriately transitioning ALIF procedures to the ASC. Further studies of preoperative characteristics are needed to elucidate ideal ASC ALIF patients.

Abstract
Background Minimally invasive transforaminal lumbar interbody fusion (MIS TLIF) is a common surgical procedure for treatment of degenerative spondylolisthesis (DS) but remains controversial for treatment of isthmic spondylolisthesis (IS). Few studies have compared IS and DS outcomes after MIS TLIF. Therefore, the objective of the current study was to compare outcomes of patients with IS and DS after MIS TLIF. Methods A retrospective cohort analysis was performed on a prospectively maintained database of patients who underwent a primary, 1-level MIS TLIF for grade I or II IS or DS. Grade I and II DS and grade I IS patients were treated with MIS TLIF via a unilateral tubular approach, whereas the grade II IS patients were treated via a bilateral tubular approach. Differences in patient demographics and preoperative characteristics were assessed using independent sample t tests and χ2 tests. The type of spondylolisthesis and its effect on postoperative outcomes was analyzed using Poisson regression with robust error variance (binary outcomes) or linear regression (continuous outcomes) adjusted for preoperative characteristics. Subgroup analysis comparing grade I IS versus DS and grade II IS versus DS was performed. Results A total of 223 patients were included (IS: 62 [27.8%]; DS: 161 [72.2%]). IS patients were younger (P < .001), had a lower comorbidity burden (P < .001), and a greater incidence of grade II spondylolisthesis (P < .001) at L5-S1 (P < .001) than the DS cohort. Patients with IS experienced longer operative times (P < .001) and lower, but not statistically significant, arthrodesis rates compared to the DS cohort. No differences were observed in the remaining preoperative patient characteristics, perioperative or postoperative outcomes. Conclusions Despite being younger and having a lower comorbidity burden than the DS cohort, similar outcomes were observed after MIS TLIF for IS patients. Level of Evidence 3. Clinical Relevance These results suggest MIS TLIF is an appropriate treatment option for IS patients despite the increased instability inherent with IS.

Abstract
Background Minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) is often used to treat low-grade isthmic spondylolisthesis (IS). No studies have compared surgical outcomes for grade I and II IS following MIS-TLIF. Therefore, the objective of the current study was to compare outcomes between patients with grade I and II IS following MIS-TLIF. Methods A retrospective cohort analysis was performed on a prospectively maintained database of patients who underwent a primary 1-level MIS-TLIF for treatment of IS between 2007 and 2015. Grade I patients underwent a unilateral tubular approach with a single interbody cage and bilateral pedicle screw instrumentation. Grade II patients underwent a bilateral tubular approach with bilateral interbody cage and pedicle screw placement. Baseline patient demographics and characteristics were compared using Student t test and χ2 analysis. Differences in peri- and postoperative outcomes were assessed using Poisson regression with robust error variance or linear regression adjusted for perioperative variables. Results A total of 58 patients with IS underwent MIS-TLIF; 21 (36.2%) were grade I and 37 (63.8%) were grade II. The grade I cohort was younger (42.2 versus 50.6 years, P = .029); no other differences in preoperative variables were observed. No significant differences in operative time, estimated blood loss, length of hospital stay, postoperative visual analogue scale scores, or complication and revision rates were demonstrated between cohorts. Arthrodesis rate was lower in the grade I cohort, though not statistically significant. Conclusions Despite the grade I cohort being younger with less-severe diagnoses, the grade II cohort experienced similar outcomes. This finding may be due to the grade II cohort receiving bilateral cages, potentially providing a better fusion environment. Clinical Relevance These results suggest that MIS-TLIF provides sufficient stabilization and fusion for treatment of grade II IS despite increased vertebral body displacement. In addition, MIS-TLIF with bilateral approach and interbody cage placement should be examined for treatment of high-grade IS cases.

Abstract
Background Prior literature has associated poor preoperative mental health with inferior patient-reported outcomes (PROs) after spinal procedures. Therefore, the objective of this study was to test for association of preoperative Short Form 12 (SF-12) mental health composite score (MCS) with improvements in Oswestry Disability Index (ODI) and back and leg visual analogue scale (VAS) pain scores after a minimally invasive transforaminal lumbar interbody fusion (MIS TLIF). Methods A surgical database of patients who underwent a primary, 1 level MIS TLIF was reviewed. Preoperative SF-12 MCS was tested for association with preoperative ODI, back VAS, and leg VAS. Preoperative MCS was then tested for association with changes in ODI, back VAS, and leg VAS from preoperative to postoperative visits. These tests were conducted using multivariate regression controlling for baseline characteristics and the preoperative score of the PRO being assessed. Results A total of 113 patients were included in the analysis. At baseline, higher preoperative MCS was associated with lower preoperative ODI (coefficient: -0.58, P < .001), lower preoperative back VAS (-0.05, P = .003), and lower preoperative leg VAS (-0.06, P = .003). However, there was no association between preoperative MCS and improvement in PROs at any postoperative timepoint (P > .05). The percent of patients achieving a minimum clinically important difference in PROs at 6 months did not differ between the bottom and top MCS halves (P > .05). Conclusions The results of this study suggest that better preoperative mental health is associated with lower perceived preoperative disability and decreased severity of back and leg pain. In contrast to other studies, the present study was unable to demonstrate that preoperative mental health is predictive of improvement in PROs at any postoperative timepoint after MIS TLIF. Level of Evidence 3. Clinical Relevance These results suggest that surgeons should exercise care in assuming that patients with poorer preoperative mental health are inferior surgical candidates.

Postoperative satisfaction following lumbar spinal fusion surgery: patient expectation versus actuality. J Neurosurg Spine 2019; 31:676-682. [PMID: 31349221 DOI: 10.3171/2019.5.spine19213] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2019] [Accepted: 05/03/2019] [Indexed: 11/06/2022]
Abstract
OBJECTIVE Due to the reported benefits associated with minimally invasive spine surgery (MIS), patients seeking out minimally invasive surgery may have higher expectations regarding their outcomes. In this study the authors aimed to assess the effects of preoperative expectations and postoperative outcome actuality, and the difference between the two, on postoperative satisfaction following MIS for lumbar fusion procedures. METHODS Patients scheduled for either a 1- or 2-level lumbar fusion MIS were administered confidential surveys preoperatively and at 6 months postoperatively. The surveys administered preoperatively consisted of 2 parts: preoperative patient-reported outcomes (PROs), including the Oswestry Disability Index (ODI), visual analog scale (VAS) back pain, and VAS leg pain, and expected postoperative PROs. The surveys administered 6 months postoperatively consisted of 2 parts: postoperative PROs and satisfaction. Preoperative symptoms, expected postoperative symptoms, and actual postoperative symptoms were compared using paired t-tests. Pearson correlation was used to compare the association between 1) postoperative change in PROs and satisfaction, 2) expectation and satisfaction, 3) expectation-actuality discrepancy and satisfaction, and 4) actuality and satisfaction. RESULTS In total, 101 patients completed all surveys. Patients expected to improve in all PROs from baseline, except for ODI personal care, in which they expected to get worse after surgery. In actuality, patients improved in all PROs from baseline, except for ODI personal care, in which they did not demonstrate improvement or worsening. Patients did not surpass any expectations regarding PRO improvement. The association between patient satisfaction and postoperative change was strong for the VAS back pain score, while ODI and VAS leg pain scores showed moderate correlations. Preoperative expectation and postoperative satisfaction demonstrated weak to moderate correlations for all outcome measures. All 3 PROs demonstrated moderate correlation between patient satisfaction and the expectation-actuality discrepancy. All 3 PROs demonstrated strong correlations between satisfaction and actual postoperative outcomes, with ODI having the strongest correlation. CONCLUSIONS In this observational study, the authors determined that the actual postoperative results following surgery were strongly correlated with patient satisfaction, while the patients' expectation, the expectation-actuality discrepancy, and the postoperative improvement did not demonstrate strong correlations for all patient-reported outcome measures utilized in this study. The investigation results suggest that the most important indicator of how satisfied patients feel following surgery may be the actual outcome itself, rather than the preoperative expectation or the degree to which the expected result was met.

Abstract
Background Several studies have compared outcomes between hospital-based centers (HBCs) and ambulatory surgery centers (ASCs) following minimally invasive lumbar decompression (MIS LD). However, the association between narcotic consumption and pain in the immediate postoperative period has not been well characterized. As such, this study aims to examine pain, narcotic consumption, and length of stay (LOS) among patients discharged on postoperative day 0 following a 1-level MIS LD between HBCs or ASCs. Methods Patients who underwent a primary, 1-level MIS LD were retrospectively reviewed and stratified by operative location. Differences between groups in patient demographics were assessed using independent-sample t tests for continuous variables and χ2 analysis for categoric variables. The operative location and its effect on perioperative characteristics, inpatient pain scores, and narcotics consumption were analyzed using multivariate linear regression adjusted for significant patient characteristics. Results There were 235 patients identified, of whom 90 and 145 underwent surgery at an HBC or ASC, respectively. The HBC cohort exhibited an increased comorbidity burden and had a greater percentage of privately insured patients. The HBC cohort recorded shorter operative time and greater total estimated blood loss. Patients in the HBC cohort experienced prolonged LOS, and consumed greater total oral morphine equivalents compared with the ASC cohort. No differences were observed in the remaining outcomes. Conclusions The results of the current study suggest that patients who underwent MIS LD at an ASC received fewer narcotics than patients treated at an HBC, which may contribute to shortened LOS. Additionally, there was no difference in patient-reported pain between cohorts despite the differences in narcotic use. As such, postoperative narcotics administration varied, indicating HBC patients perhaps required more narcotic pain medications to achieve the same pain scores that were sufficient enough to allow patient discharge, thus prolonging LOS.

Abstract
Background Study design: Retrospective cohort study. Objective: To determine which components of the swallowing disorders quality of life (SWAL-QOL) survey are most relevant to assess dysphagia following anterior cervical spine surgery (ACSS). Summary of background data: The SWAL-QOL survey is an instrument that has been applied to patients undergoing ACSS procedures as a means of objectifying swallow function. However, the SWAL-QOL is lengthy, cumbersome, and primarily used for otolaryngological procedures. Methods Patients undergoing ACSS procedures were administered the SWAL-QOL prior to surgery and at 6- and 12-week postoperative visits. The preoperative and postoperative SWAL-QOL scores were compared using paired t tests. Questions with statistically and clinically significant postoperative changes were used to create an abridged survey. Results Fifty patients completed surveys at all 3 encounters and were included in the analysis. The total scaled score at 6 weeks was significantly lower than the preoperative score (P = .003) but returned to near baseline scores by 12 weeks (P = .178). Five sections had significantly lower scores at both postoperative visits compared to their respective preoperative values. Additionally, 13 individual questions had significantly lower scores at both postoperative visits, while 8 had significantly lower scores at only 1 of the postoperative visits. Of these 21 questions demonstrating statistical significance, 16 also demonstrated a clinically significant decrease (>5.0%) from preoperative scores. These 16 questions were included in the abridged survey developed for use in ACSS patients. Conclusions The results of this study suggest that several questions in the full SWAL-QOL questionnaire demonstrated minor or no changes at postoperative visits following ACSS. As a result, we propose a modified, 16-question SWAL-QOL survey including only questions that were both statistically and clinically significant. This truncated survey may be better suited for use in cervical spine patients.

Abstract
Amid growing concern about the misuse of prescribed opioids, the rising rates of opioid use disorder, and the use of illicit opioids, clinicians in ambulatory, inpatient, and operative environments are encountering opioid-related complications in their patients. These complications can affect multiple organ systems including cardiovascular, pulmonary, gastrointestinal, and neurologic and are related to excess opioid levels in the body or contamination from non-sterile injection. It is important for the orthopedic surgeon to have a general understanding of the pathologies associated with opioid use disorder and their appearance on diagnostic imaging. This article reviews image findings of several complications, organized in a systems-based approach, for the orthopedic surgeon.

Impact of local steroid application in a minimally invasive transforaminal lumbar interbody fusion: results of a prospective, randomized, single-blind trial. J Neurosurg Spine 2019; 30:222-227. [DOI: 10.3171/2018.7.spine18584] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2018] [Accepted: 07/26/2018] [Indexed: 11/06/2022]
Abstract
OBJECTIVELocal epidural steroid application may be associated with decreased pain and narcotic use in the immediate postoperative period following lumbar discectomy. However, local steroid delivery following lumbar fusion procedures has not been well characterized. This study aims to characterize the effect of local intraoperative depomedrol application on perioperative and postoperative outcomes following a single-level minimally invasive transforaminal lumbar interbody fusion (MIS TLIF).METHODSA prospective, randomized, single-blinded study was performed. A priori power analysis determined that 86 patients were needed to detect a difference of 1 point in the visual analog scale (VAS) pain score between groups. Ninety-three patients were randomized into depomedrol (DEPO) and no depomedrol (NODEPO) cohorts. Prior to surgical closure, DEPO patients received 1 ml depomedrol (80 mg) applied directly to the surgical site by using a Gelfoam carrier. NODEPO patients received 1 ml saline on the same Gelfoam carrier. Perioperative outcomes including acute postoperative pain and narcotic use were assessed for the duration of inpatient stay. Patient-reported outcomes (PROs) questionnaires including VAS back and leg pain scores, and Oswestry Disability Index (ODI) were administered preoperatively and at 6-week, 12-week, and 6-month follow-up. Outcomes for DEPO and NODEPO cohorts were compared using linear regression controlled for sex.RESULTSOf the 93 patients, 45 (48.4%) were randomized to DEPO and 48 (51.6%) to NODEPO. A greater percentage of DEPO patients were female (53.3% vs 27.1%, p = 0.010). There were no other significant differences in patient baseline characteristics. Similarly, operating time, estimated blood loss, and length of inpatient stay did not differ between cohorts. Patients in the DEPO cohort consumed fewer hourly narcotics on postoperative day 0 (5.3 vs 6.3 oral morphine equivalents/hour, p = 0.034). However, no differences in acute postoperative pain or total narcotics consumption were observed between groups. Preoperative VAS leg scores were statistically different between cohorts (p = 0.027). However, preoperative ODI and VAS back scores did not differ between groups. Additionally, DEPO and NODEPO groups experienced similar improvements in PROs at all postoperative time points.CONCLUSIONSLocal depomedrol use did not lead to decreases in acute postoperative pain or narcotics consumption after MIS TLIF. Additionally, local depomedrol was not associated with postoperative improvements in PROs. The findings of this randomized trial suggest that surgical and clinical outcomes following MIS TLIF may not be impacted by intraoperative application of depomedrol.Clinical trial registration no.: NCT03308084 (clinicaltrials.gov)

Abstract
BACKGROUND Given the high prevalence of musculoskeletal conditions in the USA, it is important for orthopedic surgeons to promptly identify patients who may be at risk for opioid misuse. QUESTIONS/PURPOSES The aim of this literature review was to elucidate various musculoskeletal pathologies and complications, as seen on imaging, that may indicate opioid misuse or opioid use disorder. METHODS A literature search was conducted using the PubMed, Scopus, and Cochrane Library databases for articles related to imaging findings associated with chronic opioid use or misuse in orthopedic patients. Two independent reviewers conducted the search utilizing pertinent Boolean operations. RESULTS We reviewed 36 full-text articles and categorized the radiographic evidence of opioid misuse as follows: soft-tissue radiologic findings, cellulitis, necrotizing fasciitis, abscess formation, retained needles, discitis, myopathy and rhabdomyolysis, osteomyelitis, septic arthritis, and septic thrombophlebitis. CONCLUSION Knowledge of the radiologic findings of opioid misuse will assist orthopedic surgeons in making timely diagnoses that may alter therapeutic regimens for their patients.

Abstract
The ideal mode of fixation for patients with femoral neck fractures is not well defined in the current literature. This study describes the recent trends in surgical management of femoral neck fractures with an analysis on perioperative outcomes. The National Hospital Discharge Survey was used to identify femoral neck fractures in the United States between 1990 and 2007 (n = 1,155,960) treated with open reduction and internal fixation (ORIF), total hip arthroplasty (THA), or hemiarthroplasty (HA). Trends were examined over the following 3 time periods: 1990 to 1995 (group 1), 1996 to 2001 (group 2), and 2002 to 2007 (group 3). Elixhauser Comorbidity Index and perioperative complications were calculated. Use of HA increased (74.4% to 84.6%), whereas that of THA (7.3% to 4.9%) and ORIF (18.3% to 10.6%) decreased, from group 1 to group 3 in the age group of >80 years. The use of ORIF increased (63.9% to 81.4%), whereas the use of both HA and THA decreased, from group 1 to group 3 in the age group of <50 years. The rate of adverse events increased across all fixation types but was greatest among THA (32.2% to 48.3%). The femoral neck patient population is now older and has more medical comorbidities. We observed a trend toward performing HA in older patients and ORIF in younger patients. Despite superior functional outcomes reported in THA, this study found a decreased utilization of THA in all age groups along with an increase in adverse events and nonroutine discharges for patients with femoral neck fractures treated with THA.

A novel technique for stabilization of high-grade spondylolisthesis with transvertebral fusion without reduction. J Clin Neurosci 2018; 60:170-175.

Abstract
Surgical treatment of high-grade spondylolisthesis and spondyloptosis is recommended in symptomatic patients, yet there exists much debate regarding the optimal surgical approach and the need for reduction. Similar to the Bohlman technique in that fixation is achieved across two vertebral endplates, we discuss a novel technique with the advantage of using bilateral threaded pedicle screws of large diameter and length instead of a single fibula allograft. Patients underwent posterior instrumented fusion without spondylolisthesis reduction using a novel technique placing pedicle screws with a transvertebral trajectory through the two end plates involved in the spondylolisthesis. Following screw placement, patients underwent decompression ± discectomy. Screws were connected to adjacent pedicle screws either in the upper adjacent vertebrae (i.e. L5) or the more rostral adjacent vertebrae (i.e. L4) if spinal alignment or instability necessitate including additional levels of fixation. Three patients were reviewed with ages of 67, 62, 58 years, operative times of 377-790 min, estimated blood loss 400-1050 cc, and follow-up times of 478-1082 days. There were no CSF leaks, intragenic neurologic deficits post-operatively, implant failures, revisions, or other systemic events. Two patients achieve radiographic fusion assessed by CT. At the time of final follow up, all patients were satisfied and essentially pain free. This one-stage technique offers the ability to manage local malalignment with a technique that inherently minimizes risk. The minimal complications and favorable outcomes make this technique an effective, efficient and safe procedure. Additional studies will focus on long term outcomes and should include larger patient samples.

Abstract
Background Several studies have compared outcomes between hospital-based (HBCs) and ambulatory surgery centers (ASCs) following anterior cervical discectomy and fusion (ACDF). However, the association between narcotic consumption and pain in the early postoperative period has not been well characterized. As such, the purpose of this study is to compare pain, narcotic consumption, and length of stay (LOS) between HBC and ASC patients undergoing same-day-discharge following ACDF. Methods A surgical registry of patients who underwent a primary, 1- or 2-level ACDF during 2013-2015 was reviewed. Patients were stratified by operative location. Differences in demographics were assessed using independent-sample t tests and chi-square analysis. The presence of an association between operative location and outcomes was analyzed using Poisson regression with robust error variance or linear regression adjusted for preoperative characteristics. Results A total of 76 patients were identified, of which 42 and 34 underwent surgery at an HBC or ASC, respectively. The HBC cohort had greater total (P < .001) and hourly (P = .034) narcotic consumption and prolonged LOS (P < .001). Over 90% of ASC patients consumed less than or equal to the 30th percentile (32.0 mg) of oral morphine equivalents (OME), whereas over 57% of HBC patients consumed greater than 32.0 mg OME. The HBC cohort consumed greater average doses of fentanyl and oxycodone (P < .001 for each). Conclusions This study demonstrates that patients undergoing same-day surgery for primary 1- or 2-level ACDF received more narcotics at HBCs compared to at ASCs. The increased narcotic consumption at HBCs may have resulted in longer LOS; however, this did not impact long-term pain, complications, or clinical outcomes. Clinical Relevance Patients scheduled to be discharged on postoperative day 0 following ACDF at HBCs may be able to receive fewer narcotics and be discharged sooner without compromising pain control or increasing their risk for complications.
