The correlation of psoriasis and its treatment medications with lumbar discectomy postoperative infections. Spine J 2023; 23:1623-1629. [PMID: 37355045 DOI: 10.1016/j.spinee.2023.06.392] [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: 04/03/2023] [Revised: 06/07/2023] [Accepted: 06/17/2023] [Indexed: 06/26/2023]
Abstract
BACKGROUND CONTEXT Psoriasis is a chronic, autoimmune disease of the skin that affects approximately 3% of the US adult population. Patients with psoriasis may be predisposed to spine surgical site infections (SSI) related to the condition and/or related medications following surgeries such as lumbar laminotomy/discectomy. PURPOSE To assess the potential correlation of psoriasis and its related treatment medications on the risk of infection-related complications after lumbar laminotomy/discectomy. STUDY DESIGN Retrospective case control, national administrative database study. PATIENT SAMPLE Adult patients who underwent isolated single-level lumbar discectomy between 2010 and Q1 of 2021 were identified in the PearlDiver Mariner Ortho151 national administrative database (excluding those with concurrent diagnoses of fractures, neoplasms, or infections). OUTCOME MEASURES Ninety-day postoperative rates of surgical site infection and sepsis. METHODS Lumbar laminotomy/discectomy patients with versus without psoriasis were matched 1:4 based on age, sex, and Elixhauser Comorbidity Index. The risk of SSI and sepsis in the 90-day postoperative window between the cohorts were compared with multivariable analyses. Five-year reoperation rates were also compared with log rank test. The matched psoriasis cohort was further subdivided by psoriasis treatment regimens - no medication treatment (NT), topical therapies only (TT), topical therapies with oral systemic treatments (TT/OS), and topical therapies with biologics (TT/B). Multivariable logistic regression was used to assess the risk of SSI and sepsis within 90 days after lumbar laminotomy/discectomy for each treatment subgroup compared to patients without psoriasis. RESULTS In total, 2,262 patients with psoriasis who underwent single-level lumbar laminotomy/discectomy were identified and matched by age, sex, and Elixhauser Comorbidity Index to 9,044 patients without psoriasis. Multivariable logistic regression showed that, compared to the patients without psoriasis, patients with psoriasis had a 1.795 times higher chance of developing SSI (odds ratio [OR]) (p<.001) and sepsis (OR: 1.743, p=.027) within 90 days of surgery. Having psoriasis did not significantly correlate with 5-year reoperation rates. Of those with psoriasis, NT subcohort had 1,038 patients, TT subcohort 571 patients, TT/OS subcohort 226 patients, and TT/B subcohort 140 patients. Based on multivariable analysis and compared to nonpsoriasis patients, those in the NT, TT, TT/OS were not at greater odds of postoperative SSI or sepsis. Conversely, those in the TT/B subcohort were at significantly greater odds of SSI (OR: 3.102, p=.019) and sepsis (OR: 6.367, p=.027). CONCLUSIONS Of single-level lumbar laminotomy/discectomy patients with psoriasis, only those on topical therapies and biologics were at greater risk of postoperative SSI and sepsis. This subcohort warrants specific attention when undergoing lumbar laminotomy/discectomy and possibly holding such medications for a period prior to surgery may be warranted if possible.

Is There Utility to Requiring Spine MRI Pre-authorizations? Pre-authorizations: A Single Institution's Perspective. Clin Spine Surg 2023; 36:186-189. [PMID: 36728293 DOI: 10.1097/bsd.0000000000001422] [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: 05/01/2022] [Accepted: 12/13/2022] [Indexed: 02/03/2023]
Abstract
STUDY DESIGN A retrospective cohort study of a patient undergoing treatment at a single institution's Spine Center. OBJECTIVE The current study assessed the rates and eventual disposition of pre-authorizations required before spine MRIs are ordered from an academic spine center. SUMMARY OF BACKGROUND DATA Spine magnetic resonance imaging (MRI) often requires preauthorization by insurance carriers. While there are potential advantages to ensuring consistent indicators for imaging modalities, previous studies have found that such processes can add administrative burdens and barriers to care. METHODS Patients from a single academic institution's spine center who were covered by commercial insurance and had a spine MRI ordered between January 2013 and December 2019 were identified. The requirement for preauthorization and eventual disposition of each of these studies was tracked. Multivariate logistic regression was used to determine if commercial insurance carriers or anatomic region MRIs were associated with requiring a preauthorization. The eventual disposition of studies associated with this process was tracked. RESULTS In total, 2480 MRI requests were identified, of which preauthorization was needed for 2122 (85.56%). Relative to cervical spine scans, preauthorization had greater odds of being required for thoracic (OR=2.71, P =0.003) and lumbar (OR=2.46, P <0.001) scans. Relative to a reference insurer, 4 of the 5 commercial carriers had statistically significant increased odds of requiring preauthorization (OR=1.54-10.17 P <0.050 for each).Of the imaging studies requiring preauthorization, peer to peer review was required for 204 (9.61%), and 1,747 (82.33% of all requiring preauthorization) were approved. Of 375 (17.67%) initially cancelled or denied by the preauthorization process, 290 (77.33% of those initially cancelled or denied) were completed within 3 months. In total, only 85 were not eventually approved and completed. CONCLUSION Of 2480 distinct MRI orders, commercial insurers required preauthorization for 85.56%. Nonetheless, 96.57% of all scans went on to be completed within 3 months, raising questions about the costs, benefits, and overall value of this administrative process.

In-hospital complications after cervical fusion in cases with versus without cerebral palsy. NORTH AMERICAN SPINE SOCIETY JOURNAL 2022; 12:100167. [PMID: 36132746 PMCID: PMC9483629 DOI: 10.1016/j.xnsj.2022.100167] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/05/2022] [Revised: 08/29/2022] [Accepted: 08/29/2022] [Indexed: 01/22/2023]
Abstract
Background Patients with cerebral palsy (CP) are at increased risk for cervical spine pathology. Cervical fusion surgery may be considered in this population, but perioperative outcomes relative to patients without CP remains poorly understood. The purpose of this study was to compare in-hospital complications after cervical fusion in patients with versus without cerebral palsy (CP) using a retrospective cohort design. Methods Cervical fusion cases with and without CP were identified in the National Inpatient Sample (NIS) database. In-hospital adverse events were tabulated and grouped into any (AAE), serious (SAE), and minor adverse events (MAE). Length of hospital stay (LOS) and mortality were assessed. Multiple logistic regression models with and without 1:1 propensity matching were used to compare outcomes between cases with and without CP, controlling for demographic and preoperative variables. Results After weighting, 1,518,012 cases were included in the study population, of which 4,554 (0.30%) had CP. Those with CP were younger, more often male, suffered more comorbidities, more frequently operated on from a posterior or combined approach, and were more frequently addressed at more than one level. By multiple logistic regression after matching, CP cases had higher odds of AAE (OR 1.72; 95% CI 1.05-2.81; p=0.030) and MAE (OR 2.07; 95% CI 1.20-3.57; p=0.009), but no differences in odds of SAE or in-hospital mortality. Conclusions As there is increasing awareness of potentially cervical pathology in the CP population, the current study suggests that surgical intervention for this population can be appropriately considered without severe in-hospital morbidity or mortality.

Correlation of Patient Reported Satisfaction With Adverse Events Following Elective Posterior Lumbar Fusion Surgery: A Single Institution Analysis. NORTH AMERICAN SPINE SOCIETY JOURNAL 2022; 12:100160. [PMID: 36118954 PMCID: PMC9478916 DOI: 10.1016/j.xnsj.2022.100160] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/15/2022] [Revised: 05/17/2022] [Accepted: 08/08/2022] [Indexed: 01/22/2023]
Abstract
Background With increasing emphasis on patient satisfaction metrics, such as the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey, hospital reputations and reimbursements are being affected by their results. The purpose of the current study is to determine if post-operative self-reported patient satisfaction differed among patients who experienced any adverse event (AAE) following elective posterior lumbar fusion (PLF) surgery compared to those who did not. Methods Patients who underwent elective PLF surgery performed at a single institution between February 2013 and May 2020 and returned an HCAHPS survey following discharge were included in the retrospective cohort analysis. Demographic, comorbidity, and HCAHPS survey data were compared between patients who did and did not experience any adverse event (AAE) in the 30-days postoperatively. Results Of 5,117 PLF patients, the HCAHPS survey was returned by 1,071 patients, of which 30-day AAE was experienced by 40 (3.73%). Of those that experienced AAE, the survey response rate was significantly lower (13.94% versus 21.35%, p=0.003). Those responding reported lower scores pertaining to if medication side-effects were adequately explained (22.22% versus 52.56%, p=0.002) and if post-discharge care was adequately explained (79.17% versus 93.76%, p=0.005), as well as overall top-box responses (67.62% versus 75.93% survey average, p<0.001). Conclusions Patients experiencing AAE after elective PLF surgery are less likely to respond to surveys about their hospital experience. For those who did respond, they report less satisfaction with multiple aspects of their hospital care measured by the HCAHPS survey. Understanding how postoperative adverse events impact patients' perception of healthcare quality provides insight into what patients value and has implications for optimizing their care.

A comparison of in-hospital outcomes after elective anterior cervical discectomy and fusion in cases with and without Parkinson's Disease. NORTH AMERICAN SPINE SOCIETY JOURNAL 2022; 12:100164. [PMID: 36304443 PMCID: PMC9594612 DOI: 10.1016/j.xnsj.2022.100164] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/04/2022] [Revised: 08/21/2022] [Accepted: 08/23/2022] [Indexed: 01/22/2023]
Abstract
Background Following orthopedic surgery, patients with Parkinson's disease (PD) have been shown to have high rates of surgical complications, and some studies suggest that PD may be associated with greater risk for postoperative medical complications. As complication rates are critical to consider for elective surgery planning, the current study aimed to describe the association of PD with medical complications following anterior cervical discectomy and fusion (ACDF), the most commonly performed procedure to treat cervical degenerative pathology. Methods The 2008-2018 National Inpatient Sample database was queried for cases involving elective ACDF. Demographics and comorbidities were extracted using ICD codes. Cases were propensity matched based on demographic and comorbidity burden, and logistic regression was used to compare in-hospital complications between patients with and without PD. Results After weighting, a total of 1,273,437 elective ACDF cases were identified, of which 3948 (0.31%) involved cases with PD. After 1:1 propensity score matching by demographic and comorbidity variables, there were no differences between the PD and non-PD cohorts. Logistic regression models constructed for the matched and unmatched populations showed that PD cases have greater odds of in-hospital minor adverse events with no differences in odds of serious adverse events or mortality. Conclusions After matching for demographics and comorbidity burden, PD cases undergoing elective ACDF had slightly longer length of stay and greater risk for minor adverse events but had similar rates of serious adverse events and mortality. These findings are important for surgeons and patients to consider when making decisions about surgical intervention.

Admission NarxCare Narcotic Scores Are Associated With Increased Odds of Readmission and Prolonged Length of Hospital Stay After Primary Elective Total Knee Arthroplasty. J Am Acad Orthop Surg Glob Res Rev 2022; 6:01979360-202212000-00002. [PMID: 36732305 PMCID: PMC9726283 DOI: 10.5435/jaaosglobal-d-22-00040] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2022] [Accepted: 02/07/2022] [Indexed: 01/25/2023]
Abstract
INTRODUCTION The association of preoperative narcotic use with postoperative outcomes after primary elective total knee arthroplasty (TKA) has remained poorly characterized. The NarxCare platform analyzes patients' state Prescription Drug Monitoring Program records to assign numerical scores that approximate a patient's overall opioid usage. The present study investigated the utility of admission NarxCare narcotic scores in predicting the odds of adverse events (AEs) after primary elective TKA. METHODS Elective primary TKA patients performed at a single institution between October 2017 and May 2020 were evaluated. NarxCare narcotic scores at the time of admission, patient characteristics, 30-day AEs, readmissions, revision surgeries, and mortality were abstracted. Elective TKA patients were binned based on admission NarxCare narcotic scores. The odds of experiencing adverse outcomes were compared. RESULTS In total, 1136 patients met the criteria for inclusion in the study (Narx Score 0: n = 293 [25.8%], 1 to 99: n = 253 [22.3%], 100 to 299: n = 368 [32.4%], 300 to 499: n = 161 [14.2%], and 500+: n = 61 [5.37%]). By logistic regression, patients with higher admission narcotic scores tended to have a dose-dependent increase in the odds of prolonged length of hospital stay, readmission within 30 days, and aggregated AEs. DISCUSSION Admission narcotic scores may be used to predict readmission and to stratify TKA patients by risk of AEs.

Underweight patients are the highest risk body mass index group for perioperative adverse events following stand-alone anterior lumbar interbody fusion. Spine J 2022; 22:1139-1148. [PMID: 35231643 DOI: 10.1016/j.spinee.2022.02.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/01/2020] [Revised: 01/19/2022] [Accepted: 02/22/2022] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT Prior studies investigating the association between Body Mass Index (BMI) and patient outcomes following spine surgery have had inconsistent conclusions, likely owing to insufficient power, confounding variables, and varying definitions and cutoffs for BMI categories (eg, underweight, overweight, obese, etc.). Further, few studies have considered outcomes among low BMI cohorts. PURPOSE The current study analyzes how anterior lumbar interbody fusion (ALIF) perioperative outcomes vary along the BMI spectrum, using World Health Organization (WHO) categories of BMI. STUDY DESIGN/SETTING A retrospective cohort study. PATIENT SAMPLE Patients undergoing stand-alone one or two-level anterior lumbar interbody fusion (ALIF) found in the 2005-2018 American College of Surgeons National Surgical Quality Improvement Program (NSQIP) databases. OUTCOME MEASURES Thirty-day adverse events, hospital readmissions, post-operative infections, and mortality. METHODS Stand-alone one or two-level ALIF surgical cases were identified and extracted from the 2005-2018 National Surgical Quality Improvement Program (NSQIP) database. Posterior cases and those primary diagnoses of trauma, tumor, infection, or emergency presentation were excluded. Patients were then binned into WHO guidelines of BMI. The incidence of adverse outcomes within 30-day post-operation was defined. Odds ratios of adverse outcomes, normalized to the average risk of normal-weight subjects (BMI 18.5-24.9 kg/m3), were calculated. Multivariate analysis was then performed controlling for patient factors. RESULTS In total, 13,710 ALIF patients were included in the study. Incidence of adverse events was elevated in both the underweight (BMI<18.5 kg/m3) and super morbidly obese (>50 kg/m3), however, multivariate risks for adverse events and postoperative infection were elevated for underweight patients beyond those found in any other BMI category. No effect was noted in these identical variables between normal, overweight, obese class 1, or even obese class 2 patients. Multivariate analysis also found overweight patients to show a slightly protective trend against mortality while the super morbidly obese had elevated odds. CONCLUSIONS Underweight patients are at greater odds of experiencing postoperative adverse events than normal, overweight, obese class 1, or even obese class 2 patients. The present study identifies underweight patients as an at-risk population that should be given additional consideration by health systems and physicians, as is already done for those on the other side of the BMI spectrum.

COVID-positive ankle fracture patients are at increased odds of perioperative surgical complications following open reduction internal fixation surgery. PLoS One 2021; 16:e0262115. [PMID: 34972190 PMCID: PMC8719674 DOI: 10.1371/journal.pone.0262115] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2021] [Accepted: 12/17/2021] [Indexed: 12/21/2022] Open
Abstract
INTRODUCTION Ankle fractures have continued to occur through the COVID pandemic and, regardless of patient COVID status, often need operative intervention for optimizing long-term outcomes. For healthcare optimization, patient counseling, and care planning, understanding if COVID-positive patients undergoing ankle fracture surgery are at increased risk for perioperative adverse outcomes is of interest. METHODS The COVID-19 Research Database contains recent United States aggregated insurance claims. Patients who underwent ankle fracture surgery from April 1st, 2020 to June 15th, 2020 were identified. COVID status was identified by ICD coding. Demographics, comorbidities, and postoperative complications were extracted based on administrative data. COVID-positive versus negative patients were compared with univariate analyses. Propensity-score matching was done on the basis of age, sex, and comorbidities. Multivariate regression was then performed to identify risk factors independently associated with the occurrence of 30-day postoperative adverse events. RESULTS In total, 9,835 patients undergoing ankle fracture surgery were identified, of which 57 (0.58%) were COVID-positive. COVID-positive ankle fracture patients demonstrated a higher prevalence of comorbidities, including: chronic kidney disease, diabetes, hypertension, and obesity (p<0.05 for each). After propensity matching and controlling for all preoperative variables, multivariate analysis found that COVID-positive patients were at increased risk of any adverse event (odds ratio [OR] = 3.89, p = 0.002), a serious adverse event (OR = 5.48, p = 0.002), and a minor adverse event (OR = 3.10, p = 0.021). DISCUSSION COVID-positive patients will continue to present with ankle fractures requiring operative intervention. Even after propensity matching and controlling for patient factors, COVID-positive patients were found to be at increased risk of 30-day perioperative adverse events. Not only do treatment teams need to be protected from the transmission of COVID in such situations, but the increased incidence of perioperative adverse events needs to be considered.

Abstract
BACKGROUND Stability following multilevel decompressive laminectomy without fusion has been debated using in vitro biomechanical and radiographic models. However, there is a lack of information regarding clinical outcomes for these patients. The aim of the present study was to determine the association between clinical outcomes and number of levels decompressed via laminectomy for treatment of lumbar spinal stenosis. METHODS We performed a retrospective cohort analysis of patients who underwent a primary lumbar laminectomy between 2009 and 2015 by senior orthopedic spine surgeons for lumbar spinal stenosis. Patients were divided into 2 groups based on the number of decompression levels: single level or 3 or more levels. Patient-reported outcomes were obtained in the form of Oswestry Disability Index (ODI) scores, visual analog scale (VAS) scores for the back and leg, 12-Item Short Form Mental and Physical Survey scores, and Veterans Rand 12-Item Health Mental and Physical Survey scores. RESULTS Overall, 138 consecutive patients were assessed, of which 106 underwent a single-level and 32 underwent a 3-or-more-level laminectomy. Average follow-up was 24.2 months. There were no significant differences in the preoperative VAS back, VAS leg, or ODI scores between the single-level laminectomy and 3-or-more-level laminectomy groups. Both groups of patients experienced significant improvements in these clinical outcomes postoperatively with no clinically significant difference in the degree of improvement. Reoperation rates were low and similar between the 2 groups. CONCLUSIONS Patients undergoing decompression of 3 or more levels present with similar postoperative outcomes to those who undergo a single-level decompression for lumbar spinal stenosis. Under specific clinical and radiographic criteria, a multilevel decompression of 3 or more levels may be a safe and effective procedure with acceptable outcomes at 2 years after surgery. LEVEL OF EVIDENCE 3.

Abstract
With the increasing medical complexity of patients undergoing posterior lumbar surgery, more patients are pharmacologically immunosuppressed to manage chronic conditions. The effects of immunosuppression have become of greater interest across multiple surgical specialties. The goal of the current study was to investigate whether long-term corticosteroid use is independently associated with perioperative adverse outcomes among patients undergoing posterior lumbar surgery. Patients who underwent elective posterior lumbar spine surgery (decompression and/or fusion) were identified in the 2005-2016 National Surgical Quality Improvement Program (NSQIP) database. Patient factors, surgical factors, and 30-day perioperative outcomes for patients taking long-term corticosteroids were compared with those for patients who were not taking these drugs. Propensity matching and multivariate analysis were used to evaluate comparable patients while controlling for potentially confounding variables. In total, 140,519 patients undergoing posterior lumbar spine surgery were identified. Of these, 5243 (3.73%) were taking corticosteroids. After propensity matching and controlling for age, sex, body mass index, functional status, American Society of Anesthesiologists class, and surgical procedure, those taking corticosteroids were at greater risk for any adverse event (odds ratio, 1.45), a serious adverse event (odds ratio, 1.57), a minor adverse event (odds ratio, 1.47), infection (odds ratio, 1.48), reoperation (odds ratio, 1.48), and readmission (odds ratio, 1.47) (P≤.001 for each). The findings confirmed that long-term corticosteroid use is associated with significant increases in perioperative adverse outcomes for patients undergoing elective posterior lumbar surgery, even with matching and controlling for potentially confounding variables. These findings can guide patient counseling and preemptive interventions before surgery for this patient population. [Orthopedics. 2021;44(3):172-179.].

Cement Augmentation of Vertebral Compression Fractures May Be Safely Considered in the Very Elderly. Neurospine 2021; 18:226-233. [PMID: 33819949 PMCID: PMC8021820 DOI: 10.14245/ns.2040620.310] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2020] [Accepted: 01/11/2021] [Indexed: 12/31/2022] Open
Abstract
Objective The objective of the current study was to perform a retrospective review of a national database to assess the safety of cement augmentation for vertebral compression fractures in geriatric populations in varying age categories.
Methods The 2005–2016 National Surgical Quality Improvement Program databases were queried to identify patients undergoing kyphoplasty or vertebroplasty in the following age categories: 60–69, 70–79, 80–89, and 90+ years old. Demographic variables, comorbidity status, procedure type, provider specialty, inpatient/outpatient status, number of procedure levels, and periprocedure complications were compared between age categories using chi-square analysis. Multivariate logistic regressions controlling for patient and procedural variables were then performed to assess the relative periprocedure risks of adverse outcomes of patients in the different age categories relative to those who were 60–69 years old.
Results For the 60–69, 70–79, 80–89, and 90+ years old cohorts, 486, 822, 937, and 215 patients were identified, respectively. After controlling for patient and procedural variables, 30-day any adverse events, serious adverse events, reoperation, readmission, and mortality were not different for the respective age categories. Cases in the 80- to 89-year-old cohort were at increased risk of minor adverse events compared to cases in the 60- to 69-year-old cohort.
Conclusion As the population ages, cement augmentation is being considered as a treatment for vertebral compression fractures in increasingly older patients. These results suggest that even the very elderly may be appropriately considered for these procedures (level of evidence: 3).

Postoperative bracing practices after elective lumbar spine surgery: A questionnaire study of U.S. spine surgeons. NORTH AMERICAN SPINE SOCIETY JOURNAL 2021; 5:100055. [PMID: 35141620 PMCID: PMC8820027 DOI: 10.1016/j.xnsj.2021.100055] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/23/2020] [Revised: 02/14/2021] [Accepted: 02/21/2021] [Indexed: 11/25/2022]
Abstract
Background There is limited data available on the use of orthoses across varying elective spine surgeries. When previously studied in 2009, inconsistent lumbar postoperative bracing practices were reported. The present study aimed to provide a ten-year update regarding postoperative bracing practices after elective lumbar surgery among United States (U.S.) spine surgeons. Methods A questionnaire was distributed to attendees of the Lumbar Spine Research Society Annual Meeting (April 2019). The questionnaire collected demographic information, and asked surgeons to identify if they used orthoses postoperatively after ten elective lumbar surgeries. Information regarding type of brace, duration of use, and reason for bracing was also collected. Chi-square tests and one-way analysis of variance (ANOVA) were used for comparisons. Results Seventy-three of 88 U.S. attending surgeons completed the questionnaire (response rate: 83%). The majority of respondents were orthopaedic surgery-trained (78%), fellowship-trained (84%), and academic surgeons (73%). The majority of respondents (60%) did not use orthoses after any lumbar surgery. Among the surgeons who braced, the overall bracing frequency was 26%. This rate was significantly lower than that reported in the literature ten years earlier (p<0.0001). Respondents tended to use orthoses most often after stand-alone lateral interbody fusions (43%) (p<0.0001). The average bracing frequency after lumbar fusions (34%) was higher than the average bracing frequency after non-fusion surgeries (16%) (p<0.0001). The most frequently utilized brace was an off the shelf lumbar sacral orthosis (66%), and most surgeons braced patients to improve pain (42%). Of surgeons who braced, most commonly did so for 2–4 months (57%). Conclusion Most surgeon respondents did not prescribe orthoses after varying elective lumbar surgeries, and the frequency overall was lower than a similar study conducted in 2009. There continues to be inconsistencies in postoperative bracing practices. In an era striving for evidence-based practices, this is an area needing more attention.

Background Body Mass Index (BMI) is a weight-for-height metric that is used to quantify tissue mass and weight levels. Past studies have mainly focused on the association of high BMI on spine surgery outcomes and shown variable conclusions. Prior results may have varied due to insufficient power or inconsistent categorical separation of BMI groups (e.g. underweight, overweight, or obese). Additionally, few studies have considered outcomes of patients with low BMI. The aim of the current study was to analyze patients along the entirety of the BMI spectrum and to establish specific granular BMI categories for which patients become at risk for complication and mortality following posterior cervical spine surgery. Methods Patients undergoing elective posterior cervical spine surgery were abstracted from the 2005–2016 National Surgical Quality Improvement Program (NSQIP) databases. Patients were aggregated into pre-established WHO BMI categories and adverse outcomes were normalized to average risk of normal-weight subjects (BMI 18.5–24.9 kg/m2). Risk-adjusted multivariate regressions were performed controlling for patient demographics and overall health. Results A total of 16,806 patients met inclusion criteria. Odds for adverse events for underweight patients (BMI < 18.5 kg/m2) were the highest among any category of patients along the BMI spectrum. These patients experienced increased odds of any adverse event (Odds Ratio (OR) = 1.67, p = 0.008, major adverse events (OR=2.08, p = 0.001), post-operative infection (OR = 1.95, p = 0.002), and reoperation (OR = 1.84, p = 0.020). Interestingly, none of the overweight or obese categories were found to be correlated with increased risk of adverse event categories other than super-morbidly obese patients (BMI>50.0 kg/m2) for post-operative infection (OR = 1.54, p = 0.041). Conclusions The current study found underweight patients to have the highest risk of adverse events after posterior cervical spine surgery. Increased pre-surgical planning and resource allocation for this population should be considered by physicians and healthcare systems, as is often already done for patients on the other end of the BMI spectrum.

Perioperative Outcomes in 17,947 Patients Undergoing 2-Level Anterior Cervical Discectomy and Fusion Versus 1-Level Anterior Cervical Corpectomy for Treatment of Cervical Degenerative Conditions: A Propensity Score Matched National Surgical Quality Improvement Program Analysis. Neurospine 2021; 17:871-878. [PMID: 33401865 PMCID: PMC7788425 DOI: 10.14245/ns.2040134.067] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2018] [Accepted: 09/30/2018] [Indexed: 11/26/2022] Open
Abstract
Objective To compare the perioperative morbidity of 2-level anterior cervical discectomy and fusion (ACDF) with that of 1-level anterior cervical corpectomy and fusion (ACCF) for the treatment of cervical degenerative conditions.
Methods A retrospective study of the 2005–2016 National Surgical Quality Improvement Program database for patients undergoing 2-level ACDF and 1-level ACCF was performed. Patient data included: age, sex, body mass index (BMI), functional status, and American Society of Anesthesiologists (ASA) physical status (PS) classification. Hospital data included: operative time and length of hospital stay (LOS). Thirty-day outcome data included: any, serious, and minor adverse events, return to the operating room, readmission, and mortality. After propensity matching for age, sex, ASA PS classification, functional status, and BMI, multivariate logistic regression analysis was used to compare outcomes between the 2 propensity-matched subcohorts. Finally, multivariate logistic regression that additionally controlled for operative time was performed to compare the 2 propensity-matched subcohorts.
Results A total of 17,497 cases were identified, with 90.20% undergoing 2-level ACDF and 9.80% undergoing 1-level ACCF. Patients undergoing 2-level ACDF were younger, more likely to be female, had higher functional status, and had shorter operative time and LOS (p < 0.001). After propensity score matching, cases undergoing 1-level ACCF had a statistically significant higher rate of serious adverse events (p = 0.005). This difference was no longer significant after controlling for operative time.
Conclusion While there was noted to be additional morbidity in 1-level ACCF cases relative to 2-level ACDF cases, the lack of difference once controlling for the surgical time supports using the procedure that best accomplishes the surgical objectives.

A Matched Comparison of Postoperative Complications Between Smokers and Nonsmokers Following Open Reduction Internal Fixation of Distal Radius Fractures. J Hand Surg Am 2021; 46:1-9.e4. [PMID: 33390240 DOI: 10.1016/j.jhsa.2020.09.020] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2019] [Revised: 07/13/2020] [Accepted: 09/22/2020] [Indexed: 02/02/2023]
Abstract
PURPOSE The purpose of the present study was to identify differences in 30-day adverse events, reoperations, readmissions, and mortality for smokers and nonsmokers who undergo operative treatment for a distal radius fracture. METHODS The American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database was queried for patients who had operatively treated distal radius fractures between 2005 and 2017. Patient characteristics and surgical variables were assessed. Thirty-day outcome data were collected on serious (SAEs) and minor adverse events (MAEs), as well as on infection, return to the operating room, readmission, and mortality. Multivariable logistic analyses with and without propensity-score matching was used to compare outcome measures between the smoker and the nonsmoker cohorts. RESULTS In total, 16,158 cases were identified, of whom 3,062 were smokers. After 1:1 propensity-score matching, the smoking and nonsmoking cohorts had similar demographic characteristics. Based on the multivariable propensity-matched logistic regression, cases in the smoking group had a significantly higher rate of any adverse event (AAE) (odds ratio [OR], 1.75; 95% confidence interval [95% CI], 1.28-2.38), serious adverse event (SAE) (OR, 1.75; 95% CI, 1.22-2.50), and minor adverse event (MAE) (OR, 1.84; 95% CI, 1.04-3.23). Smokers also had higher rates of infection (OR, 1.73; 95% CI, 1.26-2.39), reoperation (OR, 2.07; 95% CI, 1.13-3.78), and readmission (OR, 1.83; 95% CI, 1.20-2.79). There was no difference in 30-day mortality rate. CONCLUSIONS Smokers who undergo open reduction internal fixation of distal radius fractures had an increased risk of 30-day perioperative adverse events, even with matching and controlling for demographic characteristics and comorbidity status. This information can be used for patient counseling and may be helpful for treatment/management planning. TYPE OF STUDY/LEVEL OF EVIDENCE Prognostic II.

Etiology-Based Classification of Adjacent Segment Disease Following Lumbar Spine Fusion. HSS J 2020; 16:130-136. [PMID: 32523480 PMCID: PMC7253547 DOI: 10.1007/s11420-019-09723-w] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/19/2019] [Accepted: 08/29/2019] [Indexed: 02/07/2023]
Abstract
BACKGROUND Adjacent segment disease (ASDz) is a potential complication following lumbar spinal fusion. A common nomenclature based on etiology and ASDz type does not exist and is needed to assist with clinical prognostication, decision making, and management. QUESTIONS/PURPOSES The objective of this study was to develop an etiology-based classification system for ASDz following lumbar fusion. METHODS We conducted a retrospective chart review of 65 consecutive patients who had undergone both a lumbar fusion performed by a single surgeon and a subsequent procedure for ASDz. We established an etiology-based classification system for lumbar ASDz with the following six categories: "degenerative" (degenerative disc disease or spondylosis), "neurologic" (disc herniation, stenosis), "instability" (spondylolisthesis, rotatory subluxation), "deformity" (scoliosis, kyphosis), "complex" (fracture, infection), or "combined." Based on this scheme, we determined the rate of ASDz in each etiologic category. RESULTS Of the 65 patients, 27 (41.5%) underwent surgery for neurogenic claudication or radiculopathy for adjacent-level stenosis or disc herniation and were classified as "neurologic." Ten patients (15.4%) had progressive degenerative disc pathology at the adjacent level and were classified as "degenerative." Ten patients (15.4%) had spondylolisthesis or instability and were classified as "instability," and three patients (4.6%) required revision surgery for adjacent-level kyphosis or scoliosis and were classified as "deformity." Fifteen patients (23.1%) had multiple diagnoses that included a combination of categories and were classified as "combined." CONCLUSION This is the first study to propose an etiology-based classification scheme of ASDz following lumbar spine fusion. This simple classification system may allow for the grouping and standardization of patients with similar pathologies and thus for more specific pre-operative diagnoses, personalized treatments, and improved outcome analyses.

Underweight patients are at just as much risk as super morbidly obese patients when undergoing anterior cervical spine surgery. Spine J 2020; 20:1085-1095. [PMID: 32194246 PMCID: PMC7380546 DOI: 10.1016/j.spinee.2020.03.007] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/11/2019] [Revised: 03/05/2020] [Accepted: 03/06/2020] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT Past studies have focused on the association of high body mass index (BMI) on spine surgery outcomes. These investigations have reported mixed conclusions, possible due to insufficient power, poor controlling of confounding variables, and inconsistent definitions of BMI categories (e.g. underweight, overweight, and obese). Few studies have considered outcomes of patients with low BMI. PURPOSE To analyze how anterior cervical spine surgery outcomes track with World Health Organization categories of BMI to better assess where along the BMI spectrum patients are at risk for adverse perioperative outcomes. DESIGN/SETTING Retrospective cohort study. PATIENT SAMPLE Patients undergoing elective anterior cervical spine surgery were abstracted from the 2005 to 2016 American College of Surgeons National Surgical Quality Improvement Program database. OUTCOME MEASURES Thirty-day adverse events, hospital readmissions, postoperative infections, and mortality. METHODS Patients undergoing anterior cervical spine procedures (anterior cervical discectomy and fusion, anterior cervical corpectomy, cervical arthroplasty) were identified in the 2005 to 2016 National Surgical Quality Improvement Program database. Patients were then aggregated into modified World Health Organization categories of BMI. Odds ratios of adverse outcomes, normalized to average risk of normal weight subjects (BMI 18.5-24.9 kg/m2), were calculated. Multivariate analyses were then performed on aggregated adverse outcome categories controlling for demographics (age, sex, functional status) and overall health as measured by the American Society of Anesthesiologists classification. RESULTS In total, 51,149 anterior cervical surgery patients met inclusion criteria. Multivariate analyses revealed the odds of any adverse event to be significantly elevated for underweight and super morbidly obese patients (Odds Ratios [OR] of 1.62 and 1.55, respectively). Additionally, underweight patients had elevated odds of serious adverse events (OR=1.74) and postoperative infections (OR=1.75) and super morbidly obese patients had elevated odds of minor adverse events (OR=1.72). Relative to normal BMI patients, there was no significant elevation for any adverse outcomes for any of the other overweight/obese categories, in fact some had reduced odds of various adverse outcomes. CONCLUSIONS Underweight and super morbidly obese patients have the greatest odds of adverse outcomes after anterior cervical spine surgery. The current study identifies underweight patients as an at-risk population that has previously not received significant focus. Physicians and healthcare systems should give additional consideration to this population, as they often already do for those at the other end of the BMI spectrum.

Perioperative adverse events after different fusion approaches for single-level lumbar spondylosis. ACTA ACUST UNITED AC 2020; 1:100005. [PMID: 35141578 PMCID: PMC8820031 DOI: 10.1016/j.xnsj.2020.100005] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2020] [Revised: 05/10/2020] [Accepted: 05/11/2020] [Indexed: 11/09/2022]
Abstract
Background Low back pain from lumbar spondylosis affects a large proportion of the population. In select cases, lumbar fusion may be considered. However, cohort studies have not shown clear differences in long-term outcomes between PSF, TLIF, ALIF, and AP fusion. Thus, differences in perioperative complications might affect choice between these procedures for the given diagnosis. The current study seeks to compare perioperative adverse events for patients with lumbar spondylosis treated with single-level: posterior spinal fusion (PSF), transforaminal lumbar interbody fusion (TLIF), anterior lumbar interbody fusion (ALIF), or combined anterior and posterior lumbar fusion (AP fusion). Methods Patients with a diagnosis of lumbar spondylosis who underwent single-level lumbar fusion without decompression were identified in the 2010-2016 National Quality Improvement Program (NSQIP) database. Patients were categorized based on their procedure (PSF, TLIF, ALIF, or AP fusion). Unadjusted Fisher's exact and Pearson's chi-squared tests were used to compare demographics and comorbid factors. Analysis was secondarily done with propensity score matching to address potential differences in patient selection between the study cohorts. Results In total, 1816 patients were identified: PSF n=322, TLIF n=800, ALIF n=460, AP fusion n=234. The procedures did not have different thirty-day individual or aggregated (any, serious, minor, or infection) adverse events. Further, propensity score matched analysis also revealed no differences in individual or aggregated thirty-day perioperative events. Conclusion The current study demonstrates a lack of difference in thirty-day perioperative adverse events for different fusion procedures performed for lumbar spondylosis, consistent with prior longer-term outcome studies. These findings suggest that patient/surgeon preference and other factors not captured here should be considered to determine the best surgical technique for the select patients with the given diagnosis who are considered for lumbar fusion. Summary Sentence Using the NSQIP 2010-2016 databases, this study showed that perioperative adverse events were similar for different surgical approaches of single-level fusion for single-level lumbar spondylosis.

Abstract
BACKGROUND CONTEXT Revision posterior decompression and fusion surgery for patients with symptomatic adjacent segment degeneration (ASD) is associated with significant morbidity and is technically challenging. The use of a stand-alone lateral lumbar interbody fusion (LLIF) in patients with symptomatic ASD may prevent many of the complications associated with revision posterior surgery. PURPOSE The objective of this study was to assess the clinical and radiographic outcomes of patients who underwent stand-alone LLIF for symptomatic ASD. STUDY DESIGN This is a retrospective case series. PATIENT SAMPLE We retrospectively reviewed patients with a prior posterior instrumented fusion who underwent a subsequent stand-alone LLIF for ASD by a single surgeon. All patients had at least 18 months of follow-up. Patients were diagnosed with symptomatic ASD if they had a previous lumbar fusion with the subsequent development of back pain, neurogenic claudication, or lower extremity radiculopathy in the setting of imaging, which demonstrated stenosis, spondylolisthesis, kyphosis, or scoliosis at the adjacent level. OUTCOME MEASURES Patient-reported outcomes were obtained at preoperative and final follow-up visits using the Oswestry Disability Index [ODI], visual analog scale (VAS)-back, and VAS-leg. Radiographic parameters were measured, including segmental and overall lordoses, pelvic incidence-lumbar lordosis mismatch, coronal alignment, and intervertebral disc height. METHODS Clinical and radiographic outcomes were compared between preoperative and final follow-up using paired t tests. RESULTS Twenty-five patients met inclusion criteria. The mean age was 62.0±11.3 years. The average follow-up was 34.8±22.4 months. Fifteen (60%) underwent stand-alone LLIF surgery for radicular leg pain, 7 (28%) for symptoms of claudication, and 25 (100.0%) for severe back pain. Oswestry Disability Index scores significantly improved from preoperative values (46.6±16.4) to final follow-up (30.4±16.8, p=.002). Visual analog scale-back (preop 8.4±1.0, postop 3.2±1.9; p<.001), and VAS-leg (preop 3.6±3.4, postop 1.9±2.6; p<.001) scores significantly improved following surgery. Segmental and regional lordoses, as well as intervertebral disc height, significantly improved (p<.001) and remained stable (p=.004) by the surgery. Pelvic incidence-lumbar lordosis mismatch significantly improved at the first postoperative visit (p=.029) and was largely maintained at the most recent follow-up (p=.45). Six patients suffered from new-onset thigh weakness following LLIF surgery, but all showed complete resolution within 6 weeks. Three patients required subsequent additional surgeries, all of which were revised to include posterior instrumentation. CONCLUSIONS Stand-alone LLIF is a safe and effective approach with low morbidity and acceptable complication rates for patients with symptomatic ASD following a previous lumbar fusion.

Abstract
BACKGROUND Safety data for outpatient total hip arthroplasty (THA) remains scarce. METHODS The present study retrospectively reviews prospectively collected data from the 2005-2014 American College of Surgeons National Surgical Quality Improvement Program Database. Patients who underwent THA were categorized by day of hospital discharge to be outpatient (length of stay [LOS] 0 days) or inpatient (LOS 1-5 days). Those with extended LOS beyond 5 days were excluded. To account for baseline nonrandom assignment between the study groups, propensity score matching was used. The propensity matched populations were then compared with multivariate Poisson regression to compare the relative risks of adverse events during the initial 30 postoperative days including readmission. RESULTS A total of 63,844 THA patients were identified. Of these, 420 (0.66%) were performed as outpatients and 63,424 (99.34%) had LOS 1-5 days. Outpatients tended to be younger, male, and to have fewer comorbidities. After propensity score matching, outpatients had no difference in any of 18 adverse events evaluated other than blood transfusion, which was less for outpatients than those with a LOS of 1-5 days (3.69% vs 9.06%, P < .001). CONCLUSION After adjusting for potential confounders using propensity score matching and multivariate logistic regression, patients undergoing outpatient THA were not at greater risk of 30 days adverse events or readmission than those that were performed as inpatient procedures. Based on the general health outcome measures assessed, this data supports the notion that outpatient THA can appropriately be considered in appropriately selected patients.

Abstract
Acromioclavicular (AC)jointinjury is a common orthopaedic problem that can occur following trauma, but may be underdiagnosed in patients with multiple injuries. In the polytrauma patient, X-rays are commonly done in the supine position, which leads to an underestimation of the amount of displacement of the AC joint. When suspecting an AC joint separation, upright or standing images are needed, without support of the injured arm, in order to classify the injury and guide further management. If initial films are nongravity weight- ed images, they are not adequate and further follow-up is necessary. This manuscript outlines a standard protocol for obtaining upright radiographs to evaluate the AC joint, and describes the clinical course of three polytrauma patients who initially had under-diagnosed AC joint injuries. Only after their injuries were stabilized and the patients underwent upright radiographs were their high-degree injuries demonstrated and treatment recommendations changed from nonoperative to operative intervention.

Abstract
AIMS While use of large national clinical databases for orthopaedic trauma research has increased dramatically, there has been little study of the differences in populations contained therein. In this study we aimed to compare populations of patients with femoral shaft fractures across three commonly used national databases, specifically with regard to age and comorbidities. PATIENTS AND METHODS Patients were identified in the Nationwide Inpatient Sample (NIS), National Surgical Quality Improvement Program (NSQIP) and National Trauma Data Bank (NTDB). RESULTS The distributions of age and Charleston comorbidity index (CCI) reflected a predominantly older population with more comorbidities in NSQIP (mean age 71.5; sd 15.6), mean CCI 4.9; sd 1.9) than in the NTDB (mean age 45.2; sd 21.4), mean CCI = 2.1; sd 2.0). Bimodal distributions in the NIS population showed a more mixed population (mean age 56.9; sd 24.9), mean CCI 3.2; sd 2.3). Differences in age and CCI were all statistically significant (p < 0.001). CONCLUSION While these databases have been commonly used for orthopaedic trauma research, differences in the populations they represent are not always readily apparent. Care must be taken to understand fully these differences before performing or evaluating database research, as the outcomes they detail can only be analysed in context. TAKE HOME MESSAGE Researchers and those evaluating research should be aware that orthopaedic trauma populations contained in commonly studied national databases may differ substantially based on sampling methods and inclusion criteria.

Abstract
BACKGROUND Recent studies have questioned the efficacy of meniscectomy in older patients with and without evidence of osteoarthritis; however, it continues to be frequently performed. There is limited information about age and other risk factors for adverse events and readmission after the procedure. This knowledge is vital to understand the true risk profile of this common surgery. PURPOSE To investigate if age and medical comorbidities were risk factors for postoperative adverse events and readmission after meniscectomy. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS Patients who underwent arthroscopic meniscectomy between 2005 and 2012 were identified from the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database. Age≥65 years and medical comorbidities were evaluated as risk factors for any adverse event (AAE), severe adverse events (SAEs), and readmission after meniscectomy using univariate and multivariate analyses. RESULTS A total of 17,774 patients who underwent meniscectomy were identified. The mean age was 53.0±13.6 years. A total of 3420 patients (19.2%) were ≥65 years. Overall, 208 patients (1.17%) had AAE, 203 patients (1.14%) had an SAE, and 102 patients were readmitted (0.97%). Multivariate logistic regression analyses demonstrated no significant differences between age groups for the occurrence of AAE, SAEs, and readmission. Patients with American Society of Anesthesiologists classification≥3 had increased odds of AAE (odds ratio [OR], 1.58), SAEs (OR, 1.59), and readmission (OR, 1.99). Patients with diabetes had increased odds of AAE (OR, 1.57) and SAEs (OR, 1.51). Smokers had increased odds of readmission (OR, 1.67). Patients with pulmonary disease had increased odds of AAE (OR, 1.76) and SAEs (OR, 1.70). CONCLUSION Meniscectomy is a safe procedure in older patients, as age over 65 years did not increase the odds of any of the adverse events studied. However, regardless of age, patients with an increased comorbidity burden and those with a history of smoking are at increased risk of adverse events and/or readmission after the procedure. CLINICAL RELEVANCE Knowledge of these risk factors for adverse events and readmission provides essential information for patient selection and preoperative counseling.

Abstract
There is no consensus with respect to the best procedures to preserve the knee joint in patients with osteonecrosis of the knee. We performed a systematic review of the literature between 1999 and 2012. Only 10 of 1057 studies met our inclusion criteria. Core decompression prevented additional surgical treatment in pre-collapse knees with a failure rate of 10.4% (7 of 67 knees). Autogenous and osteochondral grafts decreased the need for additional surgery in both pre-collapse (0%, 20 of 20) and post-collapse knees (10.5%, 8 of 76 knees). Although these results are quite promising multi-center randomized trials are needed to identify the optimal procedures to treat this disease.
