Abstract
The incidence of anterior cruciate ligament (ACL) reconstruction is increasing in the United States, particularly in the older athlete. Patients who undergo ACL reconstruction are at higher risk for undergoing total knee arthroplasty (TKA) later in life. TKA in patients with prior ACL reconstruction has been associated with longer operative time due in-part to difficulty with exposure and retained hardware. Outcomes after TKA in patients with prior ACL reconstruction are not well defined, with some reports showing increased rate of complications and higher risk of reoperation compared with routine primary TKA, but these results are based on small and nonrandomized cohorts. Future research is needed to determine whether graft choice or fixation technique for ACL reconstruction influences outcomes after subsequent TKA. Furthermore, whether outcomes are affected by choice of TKA implant design for patients with prior ACL reconstruction warrants further study. This review analyzes the epidemiology, operative considerations, and outcomes of TKA following ACL reconstruction.

Abstract
BACKGROUND Posterior laminectomy (LA) for resection of intradural extramedullary tumors (IDEMTs) is associated with postoperative complications, including sepsis. Sepsis is an uncommon but serious complication that can lead to increased morbidity and mortality, prolonged hospital stays, and greater costs. Given the susceptibility of a solid tumor patients to sepsis-related complications, it is important to recognize IDEMT patients as a unique population when assessing the risk factors for sepsis after laminectomy. METHODS The study design was a retrospective cohort study. Adult patients undergoing LA for IDEMTs from 2012 to 2018 were identified in the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) database. Baseline patient characteristics/comorbidities, operative and hospital variables, and 30-day postoperative complications were collected. RESULTS Of 2,027 total patients undergoing LA for IDEMTs, 38 (2%) had postoperative sepsis. On bivariate analysis sepsis was associated with superficial surgical site infection [odds ratio (OR) 11.62, P<0.001], deep surgical site infection (OR 10.67, P<0.001), deep vein thrombosis (OR 10.75, P<0.001), pulmonary embolism (OR 15.27, P<0.001), transfusion (OR 6.18, P<0.001), length of stay greater than five days (OR 5.41, P<0.001), and return to the operating room within thirty days (OR 8.72, P<0.001). Subsequent multivariate analysis identified the following independent risk factors for sepsis and septic shock: operative time ≥50th percentile (OR 2.11, P=0.032), higher anesthesia class (OR 1.76, P=0.046), dependent functional status (OR 2.23, P=0.001), diabetes (OR 2.31, P=0.037), and chronic obstructive pulmonary disease (OR 3.56, P=0.037). CONCLUSIONS These findings can help spine surgeons identify high-risk patients and proactively deploy measures to avoid this potentially devastating complication in individuals who may be more vulnerable than the general elective spine population.

Abstract
INTRODUCTION Relative value units (RVUs) are integral to the U.S. physician compensation system used by the Centers for Medicare & Medicaid Services. The use of 'work RVUs' (herein, wRVUs) is intended to reimburse physicians according to the amount of expertise and effort needed to safely and effectively perform a procedure. Our purpose was to determine: 1) the number of wRVUs/hour generated by common sports medicine surgical procedures; and 2) how patient characteristics, surgical approach, and practice setting are associated with the number of wRVUs/hour. This analysis was performed to infer whether wRVUs are assigned appropriately according to the factors on which they are purported to be based. METHODS We queried the American College of Surgeons' National Surgical Quality Improvement Program (NSQIP) database for common sports medicine surgical procedures performed in 2018. Data from 19,877 patients (8,258 women) with a mean age of 48 years (range, 18-90) who underwent a surgical sports medicine procedure were analyzed. Work RVUs and operative time were used to calculate work RVUs/hour for each surgical procedure. Univariate and multivariate analyses were used to assess correlations between patient characteristics and wRVUs/hour. RESULTS Knee chondroplasty generated the most mean (± standard deviation) wRVUs/hour at 22 ± 0.5, whereas 'open tenodesis of biceps tendon, long head' generated the least at 9.6 ± 0.25 wRVUs/hour. Factors associated with a greater mean number of wRVUs/hour were younger patient age, female sex, arthroscopic approach, and outpatient setting. Arthroscopic procedures also generated more wRVUs/hour than the same procedures performed through an open approach. wRVUs were not correlated with case complexity or surgical time. CONCLUSION wRVUs/hour in surgical sports medicine procedures vary widely depending on the procedure type, patient characteristics, surgical approach, and practice setting.

World Neurosurg 2022; 164:203-215. [PMID: 35487493 DOI: 10.1016/j.wneu.2022.04.046] [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: 02/17/2022] [Revised: 04/10/2022] [Accepted: 04/11/2022] [Indexed: 10/18/2022]
Abstract
OBJECTIVE The primary objective of our systematic review and meta-analysis was to systematically compare the reported outcomes between laminectomy and laminectomy with fixation/fusion (LF) for the treatment of intradural extramedullary tumors (IDEMTs). Our secondary objective was to compare the outcomes between different laminectomy exposure techniques. METHODS PubMed and Embase were queried for literature on laminectomy and LF for IDEMTs. Reports of transforaminal approaches, interlaminar approaches, corpectomy, pediatrics patients, intramedullary tumors, technical studies, animal or cadaver studies, and literature reviews were excluded. The outcome measures recorded were pain, neurologic function, functional independence, cerebrospinal fluid leak, and wound infection. Where possible, the laminectomy technique (partial laminectomy [PL] vs. total laminectomy [TL]) was specified. Stata, version 17, was used for the fixed effects inverse variance meta-analysis. RESULTS Of 1849 reports assessed, 17 were included. The meta-analysis revealed that laminectomy (PL or TL) resulted in higher rates of postoperative sagittal instability compared with LF (odds ratio, 1.81; P < 0.001). No differences in any other postoperative outcome were observed between laminectomy and LF (P = 0.44). The systematic review also revealed no differences in postoperative pain, neurologic function, or functional independence or disability between PL and TL. Some evidence suggested that TL might result in greater rates of sagittal instability compared with PL. CONCLUSIONS No differences between LF, PL, or TL in pain, neurologic deficit, functional independence, cerebrospinal fluid leak, or wound infection were reported. Laminectomy had greater odds of sagittal instability compared with LF. Patients with preoperative sagittal instability requiring extensive removal of the posterior spinal column to achieve adequate resection of large tumors might benefit from LF.

Abstract
STUDY DESIGN Retrospective. OBJECTIVE The purpose of this study was to assess trends in utilization rates of adult spinal deformity (ASD) surgery, as well as perioperative surgical metrics between Black and White patients undergoing operative treatment for ASD in the United States. SUMMARY OF BACKGROUND DATA Racial disparities in access to care, complications, and surgical selection have been shown to exist in the field of spine surgery. However, there is a paucity of data concerning racial disparities in the management of ASD patients. METHODS Adult patients undergoing ASD surgery from 2004 to 2014 were identified in the nationwide inpatient sample (NIS). Utilization rates, major complications rates, and length of stay (LOS) for Black patients and White patients were trended over time. Utilization rates were reported per 1,000,000 people and determined using annual census data among subpopulations stratified by race. All reported complication rates and prolonged hospital stay rates are adjusted for Elixhauser Comorbidity Index, income quartile by zip code, and insurance payer status. RESULTS From 2004 to 2014, ASD utilization for Black patients increased from 24.0 to 50.9 per 1,000,000 people, whereas ASD utilization for White patients increased from 29.9 to 73.1 per 1,000,000 people, indicating a significant increase in racial disparities in ASD utilization (P-trend < 0.001). There were no significant differences in complication rates or rates of prolonged hospital stay between Black and White patients across the time period studied (P > 0.05 for both). CONCLUSION Although Black and White patients undergoing ASD surgery do not differ significantly in terms of postoperative complications and length of hospital stay, there is a growing disparity in utilization of ASD surgery between White and Black patients from 2004 to 2014 in the United States. There is need for continued focus on identifying ways to reduce racial disparities in surgical selection and perioperative management in spine deformity surgery.Level of Evidence: 3.

Abstract
Selection of appropriate candidates for simultaneous bilateral total knee arthroplasty (si-BTKA) is crucial for minimizing postoperative complications. The aim of this study was to develop a scoring system for identifying patients who may be appropriate for si-BTKA. Patients who underwent si-BTKA were identified in the National Surgical Quality Improvement Program database. Patients who experienced a major 30-day complication were identified as high-risk patients for si-BTKA who potentially would have benefitted from staged bilateral total knee arthroplasty. Major complications included deep wound infection, pneumonia, renal insufficiency or failure, cerebrovascular accident, cardiac arrest, myocardial infarction, pulmonary embolism, sepsis, or death. The predictive model was trained using randomly split 70% of the dataset and validated on the remaining 30%. The scoring system was compared against the American Society of Anesthesiologists (ASA) score, the Charlson Comorbidity Index (CCI), and legacy risk-stratification measures, using area under the curve (AUC) statistic. Total 4,630 patients undergoing si-BTKA were included in our cohort. In our model, patients are assigned points based on the following risk factors: +1 for age ≥ 75, +2 for age ≥ 82, +1 for body mass index (BMI) ≥ 34, +2 for BMI ≥ 42, +1 for hypertension requiring medication, +1 for pulmonary disease (chronic obstructive pulmonary disease or dyspnea), and +3 for end-stage renal disease. The scoring system exhibited an AUC of 0.816, which was significantly higher than the AUC of ASA (0.545; p < 0.001) and CCI (0.599; p < 0.001). The BTK Safety Score developed and validated in our study can be used by surgeons and perioperative teams to risk stratify patients undergoing si-BTKA. Future work is needed to assess this scoring system's ability to predict long-term functional outcomes.

Abstract
BACKGROUND Racial disparities in outcomes after orthopaedic surgery have been well-documented in the fields of arthroplasty, trauma, and spine surgery; however, little research has assessed differences in outcomes after surgery for oncologic musculoskeletal disease. If racial disparities exist in the treatment of patients with pathologic long bone fractures, then they should be identified and addressed to promote equity in patient care. QUESTIONS/PURPOSES (1) How do wait times between hospital admission and operative fixation for pathologic fractures of long bones differ between Black and non-Hispanic white patients, after controlling for confounding variables using propensity score matching? (2) How does the proportion of patients with 30-day postoperative complication differ between these groups after controlling for confounding variables using propensity score matching? METHODS Using the National Surgical Quality Improvement Program database, we analyzed 828 patients who underwent fixation for pathologic fractures from 2012 to 2018. This database not only provides a large enough sample of pathologic long bone fracture patients to conduct the present study, but also it contains variables such as time from hospitalization to surgery that other national databases do not. After excluding patients with incomplete data (4% of the initial cohort), 775 patients were grouped by self-reported race as Black (12% [94]) or white (88% [681]). Propensity score matching using a 1:1 nearest-neighbor match was then used to match 94 Black patients with 94 white patients according to age, gender, BMI, American Society of Anesthesiologists physical status classification, anemia, endstage renal disease, independence in performing activities of daily living, congestive heart failure, and pulmonary disease. The primary outcome of interest was the number of days between hospital admission and operative fixation, which we assessed using a Poisson regression and report as an incidence risk ratio. The secondary outcomes were the occurrences of major 30-day postoperative adverse events (failure to wean off mechanical ventilation, cerebrovascular events, renal failure, cardiovascular events, reoperation, death), minor 30-day adverse events (reintubation, wound complications, pneumonia, and thromboembolic events), and any 30-day adverse events (defined as the pooling of all adverse events, including readmissions). These outcomes were analyzed using a bivariate analysis and logistic regression with robust estimates of variance and are reported as odds ratios. Because any results on disparities rely on rigorous control of other baseline demographics, we performed this multivariable approach to ensure we were controlling for confounding variables as much as possible. RESULTS After controlling for potentially confounding variables such as age and gender, we found that Black patients had a longer mean wait time (incidence risk ratio 1.5 [95% CI 1.1 to 2.1]; p = 0.01) than white patients. After controlling for confounding variables, Black patients also had greater odds of having any postoperative adverse event (OR 2.1 [95% CI 1.1 to 3.8]; p = 0.02), including readmission (OR 3.3 [95% CI 1.5 to 7.6]; p = 0.004). CONCLUSION The racial disparities in pathologic long bone fracture care found in our study may be attributed to fundamental racial biases, as well as systemic socioeconomic disparities in the US healthcare system. Identifying and eliminating the racial, socioeconomic, and sociocultural biases that drive these disparities would improve care for patients with orthopaedic oncologic conditions. One possible way to reduce these disparities would be to implement standardized surgical care pathways for pathological long bone fractures across different institutions to minimize variation in important aspects of care, such as time to surgical fixation. Further insight is needed on the types of standardized care pathways and the implementation mechanisms that are most effective. LEVEL OF EVIDENCE Level III, therapeutic study.

Abstract
UNLABELLED Patients with low-energy hip fractures do not follow the obesity paradox as previously reported. In datasets where injury mechanism is not available, the use of age >50 years (as opposed to commonly used >65 years) as a surrogate for a low-energy hip fracture patients may be a more robust inclusion criterion. PURPOSE: In elderly patients with a hip fracture, limited data suggests that obese patients counterintuitively have improved survival compared to normal-weight patients. This "obesity paradox" may be the byproduct of selection bias. We hypothesized that the obesity paradox would not apply to elderly hip fracture patients. METHODS The National Surgical Quality Improvement Project dataset identified 71,685 hip fracture patients ≥50 years-of-age with complete body mass index (BMI) data that underwent surgery. Patients were stratified into under and over 75-year-old cohorts (n=18,956 and 52,729, respectively). Within each age group, patients were stratified by BMI class and compared with respect to preoperative characteristics and 30-day mortality. Significant univariate characteristics (p<0.1) were included in multivariate analysis to determine the independent effect of obesity class on 30-day mortality (p<0.05). RESULTS Multivariate analysis of <75-year-old patients with class-III obesity were more likely to die within 30-days than similarly aged normal-weight patients (OR 1.91, CI 1.06-3.42, p=0.030). Multivariate analysis of ≥75-year-old overweight (OR 0.69, CI 0.62-0.77, p<0.001), class-I obese (OR 0.62, CI 0.51-0.74, p<0.001), or class-II obese (OR=0.69, CI 0.50-0.95, p=0.022) patients were less likely to die within 30-days when compared to similarly aged normal-weight patients. CONCLUSIONS Our data suggest that obesity is a risk factor for mortality in low-energy hip fracture patients, but the appearance of the "obesity paradox" in elderly hip fracture patients results from statistical bias that is only evident upon subgroup analysis.

Abstract
STUDY DESIGN Retrospective review. OBJECTIVE The primary aim was to compare length of stay (LOS) and discharge disposition of adult spinal deformity (ASD) patients undergoing surgery before and during the pandemic. Secondary aims were to compare the rates of 30-day complications, reoperations, readmissions, and unplanned emergency department (ED) visits. SUMMARY OF BACKGROUND DATA ASD patients often require extended LOS and non-routine discharge. Given resource limitations during the Coronavirus Disease 2019 (COVID-19) pandemic and caution regarding hospital stays, surgeons modified standard postoperative protocols to minimize patient exposure. METHODS We identified all patients who underwent elective thoracolumbar ASD surgery with more than or equal to five levels fusion at a tertiary care center during two distinct time intervals: July to December 2019 (Pre-COVID, N = 60) and July to December 2020 (During-COVID, N = 57). Outcome measures included LOS and discharge disposition (home vs. non-home), as well as 30-day major complications, reoperations, readmissions, and ED visits. Regression analyses controlled for demographic and surgical factors. RESULTS Patients who underwent ASD surgery during the pandemic were younger (61 vs. 67 yrs) and had longer fusion constructs (nine vs. eight levels) compared with before the pandemic (P < 0.05 for both). On bivariate analysis, patients undergoing surgery during the pandemic had shorter LOS (6 vs. 9 days) and were more likely to be discharged home (70% vs. 28%) (P < 0.05 for both). After controlling for age and levels fused on multivariable regression, patients who had surgery during the pandemic had shorter LOS (IRR = 0.83, P = 0.015) and greater odds of home discharge (odds ratios [OR] = 7.2, P < 0.001). Notably, there were no differences in major complications, reoperations, readmissions, or ED visits between the two groups. CONCLUSION During the COVID-19 pandemic, LOS for patients undergoing thoracolumbar ASD surgery decreased, and more patients were discharged home without adversely affecting complication or readmission rates. Lessons learned during the pandemic may help improve resource utilization without negatively influencing short-term outcomes.Level of Evidence: 3.

Abstract
BACKGROUND CONTEXT Little is known about the effects of sleep disturbance (SD) on clinical outcomes after spine surgery. PURPOSE To determine the (1) prevalence of SD among patients presenting for spine surgery at an academic medical center; (2) correlations between SD and health-related quality of life (HRQoL) scores; and (3) associations between postoperative SD resolution and short-term HRQoL. STUDY DESIGN Retrospective review of prospectively collected data. PATIENT SAMPLE We included 508 adults undergoing spine surgery at 1 academic center between December 2014 and January 2018. OUTCOME MEASURES Participants completed the Oswestry Disability Index (ODI) or Neck Disability Index (NDI) and Patient Reported Outcome Measurement System (PROMIS-29) questionnaire preoperatively, during the immediate postoperative period (6-12 weeks), and at 6, 12, and 24 months after surgery. METHODS Using preoperative PROMIS SD scores, we grouped participants as having no sleep disturbance (score <55), mild disturbance (score, 55-60), moderate disturbance (score 60-70), or severe disturbance (score, 70). For the final analysis, we collapsed these categories into no/mild and moderate/severe. Pearson correlation tests were used to assess correlations between SD and HRQoL measures. Regression analysis (adjusting for age, sex, comorbidities, current opioid use, and occurrence of complications) was used to estimate the effect of postoperative resolved or continuing SD on HRQoL scores and the likelihood of achieving clinically meaningful improvements in HRQoL. Alpha = 0.05. RESULTS Preoperative SD was reported by 127 participants (25%). SD was significantly correlated with worse ODI and/or NDI values and worse scores in all PROMIS health domains (all, p<.001). At the immediate postoperative assessment, SD had resolved in 80 of 127 participants (63%). Compared with participants who reported no preoperative SD, those with ongoing SD were significantly less likely to achieve clinically meaningful improvements in Pain Interference (odds ratio [OR], 0.49; 95% confidence interval [CI], 0.28, 0.84), Physical Function (OR, 0.32; 95% CI, 0.13, 0.82), and Satisfaction with Participation in Social Roles (OR, 0.57; 95% CI, 0.37, 0.80). CONCLUSION One-quarter of spine surgery patients reported preoperative SD of at least moderate severity. Poor preoperative sleep quality and ongoing postoperative sleep disturbance were significantly associated with worse scores on several HRQoL measures. These results highlight the importance of addressing patients' sleep disturbance both before and after surgery.

STUDY DESIGN Retrospective cohort study. OBJECTIVE This study aimed to evaluate the utility of the modified frailty index (mFI-5) in a population of patients undergoing spine surgery. SUMMARY OF BACKGROUND DATA The original modified frailty index (mFI-11) published as an American College of Surgeons National Surgical Quality Improvement Program 11-factor index was modified to mFI-5 after variables were removed from recent renditions. METHODS Surgical spine patients were isolated using current procedural terminology codes. mFI-11 (11) and mFI-5 (5) were calculated from 2005 to 2012. mFI was determined by dividing the factors present by available factors. To assess correlation, Spearman rho was used. Predictive values of indices were generated by binary logistic regression. Patients were stratified into groups by mFI-5: not frail (NF, <0.3), mildly frail (MF, 0.3-0.5), severely frail (SF, >0.5). Means comparison tests analyzed frailty and clinical outcomes. RESULTS After calculating the mFI-5 and the mFI-11, Spearman rho between the two indices was 0.926(P < 0.001). Each index established significant (all P < 0.001) predictive values for unplanned readmission (11 = odds ratio [OR]: 5.65 [2.92-10.94]; 5 = OR: 3.68 [1.85-2.32]), post-op complications (11 = OR: 8.56 [7.12-10.31]; 5 = OR: 13.32 [10.89-16.29]), and mortality (11 = OR: 41.29 [21.92-77.76]; 5 = OR: 114.82 [54.64-241.28]). Frailty categories by mFI-5 were: 83.2% NF, 15.2% MF, and 1.6% SF. From 2005 to 2016, rates of NF decreased (88.8% to 82.2%, P < 0.001), whereas MF increased (9.2% to 16.2%, P < 0.001), and SF remained constant (2% to 1.6%, P > 0.05). With increase in severity, postoperative rates of morbidities and complications increased. CONCLUSION The five-factor National Surgical Quality Improvement Program modified frailty index is an effective predictor of postoperative events following spine surgery. Severity of frailty score by the mFI-5 was associated with increased morbidity and mortality. The mFI-5 within a surgical spine population can reliably predict post-op complications. This tool is less cumbersome than mFI-11 and relies on readily accessible variables at the time of surgical decision-making.Level of Evidence: 3.

How is staging of ALIF following posterior spinal arthrodesis to the pelvis related to functional improvement in patients with adult spinal deformity? Spine Deform 2021; 9:1085-1091. [PMID: 33464551 DOI: 10.1007/s43390-020-00272-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/14/2020] [Accepted: 12/14/2020] [Indexed: 11/28/2022]
Abstract
STUDY DESIGN Retrospective cohort. OBJECTIVES To compare postoperative functional improvement in patients who underwent staged versus non-staged anterior-posterior spinal arthrodesis for adult spinal deformity (ASD). In patients with ASD, spinal arthrodesis can be performed in 2 stages to avoid the physiologic insult of a lengthy surgery. The association between staged surgery and postoperative functional improvement has not been well studied. METHODS We included 87 patients (59 women) with ASD who underwent anterior-posterior spinal arthrodesis of > 5 levels with fixation to the pelvis from 2010-2014. Primary outcomes were the frequency of achieving at least a minimal clinically important difference (MCID) in the Scoliosis Research Society-22r (SRS-22r) Activity domain and the timeframe in which it was achieved. The secondary outcome was patient satisfaction (SRS-22r Patient Satisfaction domain). A Cox proportional hazard model was used to compare functional improvement over time between staged and non-staged groups. Our study was powered to detect a relative hazard ratio of 0.53, β = 0.20. α = 0.05. RESULTS The frequency of achieving an MCID in SRS-22r Activity score did not differ significantly between the staged group (33/41 patients) and the non-staged group (34/46 patients) (hazard ratio 0.74; 95% confidence interval 0.41-1.36). Median times to achieving an MCID in SRS-22r Activity score were 191 days (interquartile range: 86-674) in the staged group and 181 days (interquartile range: 72-474) in the non-staged group (p = .75). The staged and non-staged groups had similar SRS-22r Patient Satisfaction scores at 3-9 months postoperatively and at final follow-up (both, p > .05). CONCLUSION Patients with ASD who underwent staged anterior-posterior spinal arthrodesis within 3 months after index surgery were similarly likely to experience functional improvement in the same timeframe as patients who underwent non-staged surgery. Patient satisfaction did not differ significantly between staged and non-staged groups. LEVEL OF EVIDENCE III.

Caudally directed upper-instrumented vertebra pedicle screws associated with minimized risk of proximal junctional failure in patients with long posterior spinal fusion for adult spinal deformity. Spine J 2021; 21:1072-1079.

Abstract
BACKGROUND CONTEXT It is unknown whether upper instrumented vertebra (UIV) pedicle screw trajectory and UIV screw-rod angle are associated with development of proximal junctional kyphosis (PJK) and/or proximal junctional failure (PJF). PURPOSE To determine whether (1) the cranial-caudal trajectory of UIV pedicle screws and (2) UIV screw-vertebra angle are associated with PJK and/or PJF after long posterior spinal fusion in patients with adult spinal deformity (ASD). STUDY DESIGN/SETTING Retrospective review. PATIENT SAMPLE We included 96 patients with ASD who underwent fusion from T9-T12 to the pelvis (>5 vertebrae fused) between 2008 and 2015. OUTCOME MEASURES Pedicle screw trajectory was measured as the UIV pedicle screw-vertebra angle (UIV-PVA), which is the mean of the two angles between the UIV superior endplate and both UIV pedicle screws. (Positive values indicate screws angled cranially; negative values indicate screws angled caudally.) We measured UIV rod-vertebra angle (UIV-RVA) between the rod at the point of screw attachment and the UIV superior endplate. METHODS During ≥2-year follow-up, 38 patients developed PJK, and 28 developed PJF. Mean (± standard deviation) UIV-PVA was -0.9° ± 6.0°. Mean UIV-RVA was 87° ± 5.2°. We examined the development of PJK and PJF using a UIV-PVA/UIV-RVA cutoff of 3° identified by a receiver operating characteristic curve, while controlling for osteoporosis, age, sex, and preoperative thoracic kyphosis. RESULTS Patients with UIV-PVA ≥3° had significantly greater odds of developing PJK (odds ratio 2.7; 95% confidence interval: 1.0-7.1) and PJF (odds ratio 3.6; 95% confidence interval: 1.3-10) compared with patients with UIV-PVA <3°. UIV-RVA was not significantly associated with development of PJK or PJF. CONCLUSIONS In long thoracic fusion to the pelvis for ASD, UIV-PVA ≥3° was associated with 2.7-fold greater odds of PJK and 3.6-fold greater odds of PJF compared with UIV-PVA <3°. UIV-RVA was not associated with PJK or PJF. LEVEL OF EVIDENCE III.

Abstract
STUDY DESIGN Retrospective review. OBJECTIVE To use predictive modeling and machine learning to identify patients at risk for venous thromboembolism (VTE) following posterior lumbar fusion (PLF) for degenerative spinal pathology. METHODS Patients undergoing single-level PLF in the inpatient setting were identified in the National Surgical Quality Improvement Program database. Our outcome measure of VTE included all patients who experienced a pulmonary embolism and/or deep venous thrombosis within 30-days of surgery. Two different methodologies were used to identify VTE risk: 1) a novel predictive model derived from multivariable logistic regression of significant risk factors, and 2) a tree-based extreme gradient boosting (XGBoost) algorithm using preoperative variables. The methods were compared against legacy risk-stratification measures: ASA and Charlson Comorbidity Index (CCI) using area-under-the-curve (AUC) statistic. RESULTS 13, 500 patients who underwent single-level PLF met the study criteria. Of these, 0.95% had a VTE within 30-days of surgery. The 5 clinical variables found to be significant in the multivariable predictive model were: age > 65, obesity grade II or above, coronary artery disease, functional status, and prolonged operative time. The predictive model exhibited an AUC of 0.716, which was significantly higher than the AUCs of ASA and CCI (all, P < 0.001), and comparable to that of the XGBoost algorithm (P > 0.05). CONCLUSION Predictive analytics and machine learning can be leveraged to aid in identification of patients at risk of VTE following PLF. Surgeons and perioperative teams may find these tools useful to augment clinical decision making risk stratification tool.

Abstract
Sciatic notch tumors are rare and have numerous etiologies. Tumor presentation varies widely and no uniform recommendations exist for approaching resection. Most studies on the topic have been small case series, with the approach dictated by surgeon experience and comfort. We provide an overview of surgical approaches for resecting sciatic notch tumors reported in the literature, as well as a conceptual framework for application of these approaches based on standard oncologic principles. The advantages and disadvantages of each approach are described on the basis of anatomic location of the tumor. For tumors that span the notch with intra- and extra-pelvic extension, notchplasty is a novel technique that provides superior visualization and access for en-bloc excision.

Abstract
OBJECTIVE Neck pain is a leading cause of years lived with disability and is often managed with opioid medications in primary care settings, though this is contraindicated by national guidelines. The aim of this study was to determine the prevalence of opioid prescription for neck pain at a primary care visit and to analyze the geographic variation and trends in opioid prescriptions between 2011 and 2017. METHODS Using a prescription drug claims database, we identified 591,961 adult patients who presented for neck pain in primary care settings between 2011 and 2017. Patients who had outpatient specialty visits within 1 year before presentation, a concomitant diagnosis of a non-musculoskeletal cause of neck pain, or preexisting chronic opioid use were excluded. RESULTS The mean age of the patients was 45 ± 12 years, and 64% were female. Fifteen percent of patients were prescribed opioids within 30 days of their encounter. Eleven percent of patients were prescribed moderate- to high-dose opioids (>20 morphine milligram equivalents). From 2011-2017, the proportion of both overall opioid prescriptions and moderate- to high-dose prescriptions given to first time presenters to an outpatient clinic for neck pain was highest in Mississippi (20%) and lowest in New Mexico (6%) (P < 0.001). In 2017, the proportion of both overall opioid prescriptions and moderate- to high-dose prescriptions was highest in the Midwest (10.4%) and lowest in the Northeast (4.9%). The proportion of patients with filled opioid prescriptions declined between 2011 (19%) and 2017 (13%) (P < 0.001), and the proportion of patients with moderate- to high-dose prescriptions declined from 2011 (13%) to 2017 (8%) (P < 0.001). first-time presenters of neck pain to an outpatient clinic. CONCLUSIONS Opioid medication use for neck pain in the primary care setting is significant. Although opioid prescriptions are declining, there remains a need for further standardization in prescription practices.

Abstract
BACKGROUND There exists a substantial risk of having a perioperative complication after revision total joint arthroplasty (TJA). The complex shared decision-making between surgeon and patient would benefit from a high-fidelity tool to identify patients at risk for mortality after revision TJA. Therefore, we developed the CARDE-B score. CARDE-B is an acronym for congestive heart failure, albumin or malnutrition (<3.5 mg/dL), renal failure on dialysis, dependence for daily living, elderly (>65 years of age), and body mass index <25 kg/m2. We developed and validated the CARDE-B score to determine the risk of death within 30 days of a revision TJA. METHODS A total of 13,118 revision TJAs (40% hip and 60% knee) from the National Surgical Quality Improvement Program (NSQIP) database were analyzed. A simple 1-point scoring system, CARDE-B, was created for predicting 30-day mortality after revision TJA, based on a logistic regression model. The CARDE-B scoring system assigns 1 point to each criterion in the acronym: congestive heart failure, albumin (<3.5 mg/dL), renal failure on dialysis, dependence for daily living, elderly (>65 years of age), and body mass index of <25 kg/m2. The CARDE-B scoring system was compared with 2 commonly utilized scores: American Society of Anesthesiologists (ASA) physical status classification and the 5-factor modified frailty index (mFI-5). The area under the curve (AUC) was used to assess the accuracy of each model. The Hosmer-Lemeshow test was used to assess goodness of fit. Finally, the Nationwide Inpatient Sample (NIS) was used for external validation of the CARDE-B score in 19,153 patients who underwent revision TJA in 2017. RESULTS Eighty-eight patients (0.7%) did not survive 30 days after revision TJA. The AUC for the logistic regression model was 0.88 in both the derivation and internal validation samples using NSQIP. The predicted probability of 30-day mortality after revision TJA increased stepwise from <0.01% for a CARDE-B score of 0 points to 39% for a CARDE-B score of 5 points. The AUC for the CARDE-B score predicting 30-day mortality after revision TJA was 0.85. This was more accurate (p < 0.001) than the ASA physical status classification (AUC, 0.77) and the mFI-5 (AUC, 0.67). The AUC for the CARDE-B score in the NIS external validation set was 0.75. The Hosmer-Lemeshow p value for goodness of fit was 0.34, indicating goodness of fit in the external validation sample. CONCLUSIONS The CARDE-B score is a simple system that predicts the risk of death within 30 days of a revision TJA, offering surgeons and patients a valuable and validated risk-stratification tool.

Abstract
STUDY DESIGN Retrospective review of an administrative database. OBJECTIVES The aim of our study was to investigate the distribution of spending for the entire episode of care among nonelderly, commercially insured patients undergoing elective, inpatient anterior cervical discectomy and fusion (ACDF) surgeries for degenerative cervical pathology. METHODS Using a private insurance claims database, we identified patients who underwent single-level, inpatient ACDF for degenerative spinal disease. Patients were selected using a combination of Current Procedural Terminology (CPT) and International Classification of Diseases (ICD) codes. Entire episode of care was defined as 6-months before (preoperative) to 6 months after (postoperative) the surgical admission. RESULTS In our cohort containing 33 209 patients, perioperative median spending per patient (MSPP) within the year encompassing surgery totaled $37 020 (interquartile range [IQR] $28 363-$49 206), with preoperative, surgical admission, and postoperative spending accounting for 9.8%, 80.7%, and 9.5% of total spending, respectively. Preoperatively, MSPP was $3109 (IQR $1806-$5215), 48% of patients underwent physical therapy, and 31% underwent injections in the 6 months period prior to surgery. Postoperatively, MSPP was $1416 (IQR $398-$3962), and unplanned hospital readmission (6% incidence) accounted for 33% of the overall postoperative spending. Discharge to a nonhome discharge disposition was associated with higher postoperative spending ($14 216) compared with patients discharged home ($1468) and home with home care ($2903), P < .001. CONCLUSION Understanding the elements and distribution of perioperative spending for the episode of care in patients undergoing ACDF surgery for degenerative conditions is important for health care planning and resource allocation.

Abstract
We investigated geographic variation in percentage of private insurance payments to United States physicians for commonly performed orthopaedic procedures. We queried a private administrative claims database for patients who underwent inpatient total knee arthroplasty (TKA), total hip arthroplasty (THA), single-level anterior cervical discectomy and fusion (ACDF), and posterior lumbar fusion (PLF) from 2010 to 2017. Percentage of total payments to physician (PPP) was calculated by dividing physician payments by total payments. Analysis of variance was used to determine geographic differences in PPP. A total of 542,530 patients were included, mean age was 55 ± 8. PPP significantly varied between states for all four procedures (p < 0.001); Colorado and Alabama had the lowest and highest PPP, respectively. There was a significant annual decrease in PPP across all regions in all procedures. There was significant variation in percentage of total payments to physicians across geographic regions in the United States for TKA, THA, ACDF and PLF.

Abstract
Objective Lumbar discectomy is commonly performed for symptomatic lumbar disc herniation. We aimed to examine prescribing patterns and risk factors for chronic opioid use following lumbar discectomy.
Methods Using a private insurance claims database, patients were identified who underwent primary lumbar discectomy from 2010–2015 and had 1-year of continuous enrollment postoperatively. Patients were excluded with spinal fusion. The strength of opioid prescriptions was quantified using morphine milligram equivalents daily (MMED). Univariate and multivariate logistic regression models were built to examine risk factors associated with chronic postoperative opioid use.
Results A total of 5,315 patients were included in the study (mean age, 59 years; 50% female). 1,198 of patients (23%) used chronic opioids postoperatively. Chronic opioid use declined significantly from 27% in 2010 to 17% in 2015, p < 0.001. In addition, there were significantly fewer patients receiving high and very high-dose opioid prescriptions from 2010–2015, p < 0.001. The median duration that patients used opioids postoperatively was 211 days in 2010 (interquartile range [IQR], 29–356 days), and decreased significantly to 44 days (IQR, 10–294 days) in 2015. The strongest factors associated with chronic opioid use were preoperative opioid use (odds ratio [OR], 4.0), drug abuse (OR, 2.6), depression (OR, 1.6), surgery in the west (OR, 1.6) or south (OR, 1.6), anxiety (OR, 1.5), or 30-day readmission (OR, 1.4).
Conclusion Chronic opioid use following primary lumbar discectomy has declined from 2010–2015. A variety of factors are associated with chronic opioid use. Preoperative recognition of some of these risk factors may aid in perioperative management and counseling.

Abstract
Objective The aim of this study was to compare all-cause reoperation rates and costs in nonelderly patients treated with anterior cervical discectomy and fusion (ACDF) with structural allograft versus synthetic cages for degenerative pathology.
Methods We queried a private claims database to identify adult patients (≤ 65 years) who underwent single-level ACDF in a hospital setting using either structural allograft or a synthetic cage (polyetheretherketone, metal, or hybrid device), from 2010 to 2016. The rate of all-cause reoperations at 2 years were compared between the 2 groups. Index hospitalization costs and 90-day complication rates were also compared. Significance was set at p < 0.05.
Results A total of 26,754 patients were included in the study. 11,514 patients (43%) underwent ACDF with structural allograft and 15,240 (57%) underwent ACDF with a synthetic cage. The patients in the allograft group were younger and more likely to be male. There was no significant difference between the 2 groups with respect to 90-day complications including: wound dehiscence, dysphagia, dysphonia, and hematoma/seroma. In the 2-year postoperative period, the synthetic cage group had a significantly higher rate of allcause reoperation compared to the allograft group (9.1% vs. 8.0%, p = 0.002). Index hospitalization costs were significantly higher in the synthetic cage group compared to those in the allograft group ($23,475 vs. $20,836, p < 0.001).
Conclusion Structural allograft is associated with lower all-cause reoperation rates and lower index costs in nonelderly patients undergoing ACDF surgery for degenerative pathology. It is important to understand this data as we transition toward value-based care.

Abstract
STUDY DESIGN Retrospective review. OBJECTIVE To identify national trends in postoperative opioid prescribing practices after posterior spinal fusion (PSF) in patients with adolescent idiopathic scoliosis (AIS). Opioids are an important component of pain management after PSF for AIS. Given the national opioid crisis, it is important to understand opioid prescribing practices in these patients. METHODS Using a commercial prescription drug claims database, we identified AIS patients who underwent PSF from 2010 to 2016 and who were prescribed opioids postoperatively. An initial prescription at hospital discharge of ≥ 90 morphine milligram equivalents daily (MMED) was used to identify patients at risk of overdose according to the US Centers for Disease Control and Prevention (CDC) guidelines. Prescriptions for skeletal muscle relaxants were also identified. α = 0.05. RESULTS We included 3762 patients (75% female) with a mean (± standard deviation) age of 15 ± 2.1 years. 56% of patients filled only 1 opioid prescription after discharge, and 44% had ≥ 1 refills. 91% of opioid prescriptions were for hydrocodone (median strength, 43 MMED; mean strength, 65 ± 270 MMED) or oxycodone formulations (median strength, 60 MMED; mean strength, 79 ± 174 MMED). 82% of prescriptions complied with CDC guidelines (< 90 MMED). Overall, 612 patients (16%) filled ≥ 1 prescription for skeletal muscle relaxants, the most common being cyclobenzaprine (45%) and methocarbamol (29%). The percentage of patients filling > 1 prescription declined from 54% in 2010 to 31% in 2016 (p < 0.001). The proportion of patients receiving prescriptions for ≥ 90 MMED was highest in the West (29%) and lowest in the South (16%) (p < 0.001). CONCLUSION Most opioid prescriptions after PSF in patients with AIS comply with CDC guidelines. Temporal and geographic variations show an opportunity for standardizing opioid prescribing practices in these patients. LEVEL OF EVIDENCE III.
