Abstract
BACKGROUND CONTEXT Sickle cell disease (SCD) is an inherited disorder of red blood cells caused by mutation in the hemoglobin beta chain and is the most common inherited genetic disorder in the United States. Postoperative outcomes following single-level posterior lumbar interbody fusion (PLIF) in patients with SCD are not well characterized. PURPOSE To examine 90-day postoperative outcomes among a matched cohort of patients with and without SCD who underwent single level PLIF utilizing a national administrative database. STUDY DESIGN/SETTING Retrospective database study. PATIENT SAMPLE Adult patients without and with SCD who underwent single level PLIF from 2010 to 2021 Q1 were identified and matched 10:1 based on age, sex and ECI. Exclusion criteria included: age <18 years old, recent history of infection, neoplasm, or trauma, as well as not being active in the database for 90 days following their procedure. OUTCOME MEASURES Ninety-day postoperative adverse events and emergency department (ED) visits. METHODS The matched cohorts were defined, and 90-day adverse event and ED visit rates were compared with univariable analyses and multivariable logistic regression, controlling for age, sex, and Elixhauser comorbidity index (ECI). RESULTS Overall, 191,765 PLIF patients were identified, of which SCD was noted for 76 (0.04%). On multivariable analysis of the matched populations, patients with SCD were at increased odds ratio (OR) of the following (in decreasing OR order): transfusion (OR 17.69), pneumonia (OR 6.30), sepsis (OR 4.86), aggregated minor adverse events (OR 4.65), aggregated all adverse events (OR 3.87), ED visits (OR 3.53), and aggregated severe adverse events (OR 2.80) (p<.05 for all). CONCLUSIONS The current study examined a relatively small, but largest to date, cohort of SCD patients undergoing PLIF. Patients with this condition were at greater odds of several perioperative adverse events, and these findings may be helpful for patient counselling and surgical planning.

Abstract
BACKGROUND Prior studies have compared perioperative opioid prescriptions between carpal tunnel release (CTR) performed wide-awake and with traditional anesthetic techniques, but the association of opioid prescriptions with surgical setting has not been fully explored. The current study assessed the association of opioid prescriptions with surgical setting (office or operating room) for wide-awake CTR. METHODS Patients with open CTR were identified in an administrative claims database (PearlDiver). Exclusion criteria included age less than 18 years, preoperative data less than 6 months, postoperative data less than 1 month, bilateral surgery, concomitant hand surgery, and traditional anesthesia (general anesthesia, sedation, or regional block). Patients were stratified by surgical setting (office or operating room) and matched by age, sex, Elixhauser Comorbidity Index, and geographic region. Prior opioid prescriptions, opioid dependence/abuse, substance use disorder, back/neck pain, generalized anxiety, and major depression were identified. Opioid prescriptions within 7 days before and 30 days after surgery were characterized. RESULTS Each matched cohort included 5713 patients. Compared with patients with surgery in the operating room, fewer patients with office-based surgery filled opioid prescriptions (45% vs 62%), and those prescriptions had lower morphine milligram equivalents (MMEs, median 130 vs 188). These findings were statistically significant on univariate and multivariate analysis. CONCLUSIONS Following office-based CTR, fewer patients filled opioid prescriptions, and filled prescriptions had lower MME. This likely reflects patient and provider attitudes about pain control and opioid utilization. Further patient- and provider-level investigation may provide additional insights that could aid in efforts to reduce perioperative opioid utilization across surgical settings.

Abstract
INTRODUCTION Total knee arthroplasty (TKA) is a common procedure for which patient factors are known to affect perioperative outcomes. Asthma has not been specifically considered in this regard, although it is the most common inflammatory airway disease and predisposes to osteoarthritis. METHODS Adult patients undergoing TKA were identified from 2015 to 2021-Q3 M157 PearlDiver data sets. Asthma patients were matched to those without 1:1 based on age, sex, and Elixhauser Comorbidity Index (ECI). The incidence of 90-day adverse events and 5-year revisions were compared using multivariable logistic regression (P < 0.0023). The matched asthma group was then stratified based on disease severity for analysis of 90-day aggregated (any, severe, and minor) adverse events. RESULTS Among 721,686 TKA patients, asthma was noted for 76,125 (10.5%). Multivariable analysis revealed that patients with asthma were at increased odds of multiple 90-day pulmonary, non-pulmonary, and aggregated adverse events, as well as emergency department visits. Furthermore, patients with asthma had 1.17 times greater odds of 5-year revisions (P < 0.0001). Upon secondary analysis stratifying asthma by severity, patients with all severity levels of asthma showed elevated odds of adverse events after TKA. These associations increased in odds with increasing severity of asthma. DISCUSSION Over one-tenth of patients undergoing TKA were identified as having asthma, and these patients were at greater odds of numerous pulmonary and non-pulmonary adverse events (a trend that increased with asthma severity), as well as 5-year revisions. Clearly, patients with asthma need specific risk mitigation strategies when considering TKA. LEVEL OF EVIDENCE III.

Abstract
BACKGROUND Total hip arthroplasty (THA) is a common procedure following which postoperative visits are important to optimize outcomes. The associated global billing period includes the 90 postoperative days (or approximately 13 weeks), during which professional billing is included with the surgery itself. The current study assessed clinical practice patterns relative to the global billing period. METHODS Using the PearlDiver M91Ortho dataset, the incidence and timing of Evaluation and Management (E&M) codes in the 26 weeks following THA were assessed. The follow-up visits within and beyond the global billing period, and those conducted by surgeons versus non-surgeon advanced practice providers (APPs) were determined. RESULTS 77,843 THAs were identified. Follow-up visits peaked at postoperative weeks 3, 7, and 14. The greatest week-to-week variation in the number of follow-ups was from weeks 13 to 14 immediately following the global billing period (representing a greater than 4-fold increase in visits.) During the first 13 postop weeks, 73.8% of patients were seen by orthopedic surgeons (as opposed to APPs). In the following 13 weeks, a significantly greater percentage of visits were with surgeons (86.8%, p<0.0001). CONCLUSIONS Following the THA global billing period, there was marked increase in the number of follow-ups and transition to a greater percentage being performed by the surgeons. These results provide interesting insight into the potential impact of the billing structure on how practice is pursued.

Abstract
STUDY DESIGN Retrospective cohort analysis. OBJECTIVE To assess the evolution of patients undergoing sacroiliac (SI) fusion with minimally invasive surgery (MIS) relative to open approaches. SUMMARY OF BACKGROUND DATA The SI joint can be a contributor to lumbopelvic symptoms. The MIS approach to SI fusion has been shown to have fewer complications compared with the open approach. Recent trends and evolved patient populations have not been well-characterized. MATERIALS AND METHODS Data were abstracted from the large, national, multi-insurance, administrative 2015-2020 M151 PearlDiver database. The incidence, trends, and patient characteristics of MIS, as well as open, SI fusions for adult patients with degenerative indications, were determined. Univariable and multivariable analyses were then performed to compare the MIS relative to open populations. The primary outcome was to assess the trends of MIS and open approaches for SI fusions. RESULTS In total, 11,217 SI fusions were identified (of which 81.7% were MIS), with a clear increase in numbers over the years from 2015 (n=1318, 62.3% of which were MIS) to 2020 (n=3214 86.6% of which were MIS). Independent predictors of MIS (as opposed to open) SI fusion included: older age (odds ratio [OR] 1.09 per decade increase), higher Elixhauser-Comorbidity Index (OR 1.04 per two-point increase), and geographic region (relative to South, Northeast OR 1.20 and West OR 1.64). As might be expected, 90-day adverse events were lower for MIS than open cases (OR 0.73). CONCLUSION The presented data quantify the increasing incidence of SI fusions over the years, with the increase being driven by MIS cases. This was largely related to an expanded population (those who are older and with greater comorbidity), fitting the definition of disruptive technology with lesser adverse events than open procedures. Nonetheless, geographic variation highlights the differential adoption of this technology.

Abstract
INTRODUCTION Patients with cystic fibrosis (CF) are living longer and may be considered for total hip arthroplasty (THA) or total knee arthroplasty (TKA). Perioperative outcomes and implant survival after these procedures performed for those with CF have not been previously described. METHODS Using the M151 PearlDiver database, a large, national, administrative database, THA and TKA patients with and without CF were identified and matched 1:10 based on age, sex, and Elixhauser Comorbidity Index. Ninety-day perioperative outcomes and 2-year revision rates were assessed and compared with multivariable logistic regression. RESULTS For THA, 185 patients with CF were matched with 1,846 control subjects without CF. Patients with CF were at significantly increased odds of 90-day postoperative events including sepsis (odd radio [OR] 4.15), pneumonia (OR 3.40), pleural effusion (OR 2.77), minor events (OR 1.73), any adverse event (OR 1.64), urinary tract infection (UTI) (OR 1.63), and severe events (OR 1.60) ( P < 0.05 for each). For TKA, 505 patients with CF were matched with 5,047 control subjects without CF. Patients with CF were at significantly increased odds of 90-day postoperative events including pneumonia (OR 4.95), respiratory failure (OR 4.31), cardiac event (OR 2.29), minor events (OR 2.16), pleural effusion (OR 2.35), severe events (OR 2.06), urinary tract infection (OR 2.06), any adverse event (OR 1.96), atelectasis (OR 1.94), and acute kidney injury (OR 1.61) ( P < 0.05 for each). For both THA and TKA, those with CF were not at greater odds of 2-year rates of revision. DISCUSSION After THA and TKA, those with CF were found to be at increased odds of multiple defined postoperative events (predominantly infectious/pulmonary), but not 2-year revision rates. These findings help define areas in need of focused optimization and are reassuring regarding risks of surgery.

Abstract
STUDY DESIGN/SETTING Retrospective study. OBJECTIVE To understand why patients utilize emergency departments (EDs) versus urgent care centers for low back pain (LBP). SUMMARY OF BACKGROUND DATA LBP is a common reason for ED visits. In the setting of trauma or recent surgery, the resources of EDs may be needed. However, urgent care centers may be appropriate for other cases. MATERIALS AND METHODS Adult patients below 65 years of age presenting to the ED or urgent care on the day of diagnosis of LBP were identified from the 2019 PearlDiver M151 administrative database. Exclusion criteria included history of radiculopathy or sciatica, spinal surgery, spinal cord injury, other traumatic, neoplastic, or infectious diagnoses in the 90 days prior, or Medicare insurance. Patient age, sex, Elixhauser comorbidity index, geographic region, insurance, and management strategies were extracted. Factors associated with urgent care relative to ED utilization were assessed using multivariable analysis. RESULTS Of 356,284 LBP patients, ED visits were identified for 345,390 (96.9%) and urgent care visits for 10,894 (3.1%). Factors associated with urgent care use relative to the ED were: geographic region [relative to Midwest; Northeast odds ratio (OR): 5.49, South OR: 1.54, West OR: 1.32], insurance (relative to Medicaid; commercial OR: 4.06), lower Elixhauser comorbidity index (OR: 1.28 per two-point decrease), and higher age (OR: 1.10 per decade), female sex (OR: 1.09), and use of advanced imaging (OR: 0.08) within 1 week ( P <0.001 for all). CONCLUSIONS Most patients presenting for a first diagnosis of isolated LBP went to the ED relative to urgent care. The greatest drivers of urgent care versus ED utilization for LBP were insurance type and geographic region. Utilization of advanced imaging was higher among ED patients, but rates of surgical intervention were similar between those seen in the ED and urgent care.

Abstract
BACKGROUND CONTEXT Lumbar discectomy is a commonly performed surgery following which surgical site infection (SSI) may occur. Prior literature has suggested that, following SSI related to lumbar fusion, the rate of subsequent lumbar surgeries is increased over prolonged periods of time. This has not been studied specifically for lumbar discectomy. PURPOSE To define factors associated with SSI following lumbar discectomy and determine if subsequently matched cohorts with and without SSI have differential rates of subsequent lumbar surgery beyond irrigation and debridement (I&Ds) over time. STUDY DESIGN/SETTING Retrospective cohort study. PATIENT SAMPLE Adult patients undergoing isolated primary lumbar laminotomy/discectomy were identified from the 2010-2021 M157PearlDiver database. Exclusion criteria included: age<18 years, preoperative diagnosis of infection, neoplastic, or traumatic diagnoses within 90 days prior to index surgery, additional spinal surgeries on the same day as lumbar discectomy, and not being active in the database for at least 90 days postoperative. From this study population, those who developed SSI were identified based on undergoing I&D within 90 days after surgery. Those with versus without SSI were then matched 1:4 based on age, sex, Elixhauser Comorbidity Index (ECI), and obesity. OUTCOME MEASURES Following initial I&D, incidence of revision lumbar surgery (revision lumbar discectomy, lumbar laminectomy, lumbar fusion) out to 5 years after lumbar discectomy. METHODS Following index isolated lumbar discectomy, those with versus without SSI requiring I&D were matched and compared for incidence of secondary surgery in defined time intervals (0-6 months, 6-12 months, 1-2 years, 2-5 years) using multivariable logistic regression, controlling for patient age, sex, ECI, and obesity status. RESULTS Of 323,025 isolated lumbar discectomy patients, SSI requiring I&D was identified for 583 (0.18%). Multivariable analysis revealed several independent predictors of these SSIs: younger age (odds ratio [OR] 0.85 per decade increase), ECI (OR 1.22 per 2-point increase), and obesity (OR 1.30). Following matching of those with versus without SSI requiring I&D, rates of subsequent surgery beyond I&D were compared. Those with SSI had significantly increased odds of lumbar revision in the first six months (OR 5.26, p<.001), but not 6-12 months (p=.462), 1-2 years (p=.515), or 2-5 years (p=.677). CONCLUSIONS Overall, SSI requiring I&D is a rare postoperative complication following lumbar discectomy. If occurring, subsequent surgery beyond I&D was higher in the first six months, but then not increased at subsequent time points out to five years.

Abstract
PURPOSE To compare 90-day complications, 30-day emergency department (ED) visits, and 5-year rate of secondary surgeries for patients with Medicaid vs commercial insurance undergoing primary hip arthroscopy for femoroacetabular impingement syndrome (FAIS) and/or labral tears using a large national database. METHODS The PearlDiver Mariner151 database was used to identify patients with International Classification of Diseases, Tenth Revision diagnosis codes for FAIS and/or labral tear who underwent primary hip arthroscopy with femoroplasty, acetabuloplasty, and/or labral repair between 2015 and 2021. Patients with Medicaid were matched 1:4 to a control group of commercially insured patients based on age, sex, body mass index, and Elixhauser Comorbidity Index. Rates of 90-day complications and 30-day ED visits were compared using multivariate regression models. Five-year rates of secondary surgeries-revision arthroscopy or total hip arthroplasty-were compared between cohorts by Kaplan-Meier analysis. RESULTS A total of 2,033 Medicaid patients were matched with 8,056 commercially insured patients. Rates of adverse events were low; however, Medicaid patients were significantly more likely than commercially insured patients to experience any 90-day complication (2.12% vs 1.43%; odds ratio [OR], 1.2; P = .02). Medicaid patients also experienced more 30-day ED visits than commercially insured patients (8.61% vs 4.28%), and on multivariate logistic regression, insurance status was the strongest determinant of 30-day ED visits (relative to commercial, Medicaid OR, 2.02; P < .001). Despite these differences, 5-year rates of secondary surgeries were comparable between groups (6.1% vs 6.0%; P = .6). CONCLUSIONS In this large national database study, Medicaid patients undergoing primary hip arthroscopy showed significantly greater odds of experiencing 90-day postoperative complications and 30-day ED visits compared to commercially insured patients. Nevertheless, both groups had similar survivorship rates at 5-year follow-up, similar to prior estimates irrespective of insurance. These results document encouraging secondary surgery rates in Medicaid patients.

Abstract
PURPOSE Posterior scoliosis fusion (PSF) for adolescent idiopathic scoliosis (AIS) is considered a highly successful surgery with excellent outcomes. However, especially as many patients "graduate" from their pediatric surgeons, there is the need to quantify the long-term outcomes of such surgeries. METHODS The 2010-2022 Pearldiver M161 dataset was queried for those who were 10 to 18 years old with AIS undergoing PSF with at least 10 years follow-up. Patient characteristics were abstracted. Reoperations were identified based on coding for any subsequent thoracic/lumbar surgery/revision. The 10-year reoperation rate and reasons for reoperation were determined, and multivariate regression was performed to determine risk factors. RESULTS In total, 3,373 AIS PSF patients were identified. Of the study cohort, 324 (9.6%) underwent reoperation within 10-years with an interquartile range for timing of surgery of 81-658 days, of which 29.6% were done for infection. Reoperations were done within the first three months for 152 (46.9% of reoperations), three months to 2 years for 97 (29.9%), and 2 years to 10 years for 74 (22.8%). Based on multivariate regression, need for reoperation was associated with male sex (OR: 1.70), asthma (OR: 1.36) and greater than thirteen segments of instrumentation (OR: 1.48) (p < 0.05 for each) but not age, other comorbidities, or insurance. CONCLUSIONS The current study of a large national AIS PSF population found 9.6% to undergo reoperation in the 10 years following their index operation. Although specifics about the curve pattern could not be determined, the reoperation incidence and correlation with specific risk factors are notable and important for patient counselling.

Abstract
PURPOSE To evaluate sex-based differences in 30-day postoperative emergency department (ED) visits, 90-day complication rates, and 2-year secondary surgery rates after the Latarjet procedure for the treatment of recurrent shoulder instability. METHODS A national administrative claims database was used to identify patients with International Classification of Diseases, Tenth Revision (ICD-10) diagnosis codes for shoulder subluxation or dislocation on the day of first-time stabilization with the Latarjet technique between 2015 and 2021. Male patients were matched 4:1 to female patients based on age, Elixhauser Comorbidity Index (ECI) score, and body mass index class. Rates of 30-day ED visits and 90-day complications were compared between cohorts, and risk factors for ED visits were identified by multivariate regression. The incidence of secondary surgery within 2 years was compared by Kaplan-Meier analysis. RESULTS Prior to matching, 1,059 male and 360 female patients met the inclusion and exclusion criteria. Subsequent 4:1 (male-to-female) matching controlling for age, ECI score, and body mass index yielded 694 male and 185 female patients who underwent the Latarjet procedure. The overall incidence of 30-day ED visits was 9.3%, with an incidence of 8.2% for male patients and 13.5% for female patients. On the basis of multivariate logistic regression, these 30-day ED visits were associated with female sex (odds ratio, 1.79; P = .029) and incrementally higher ECI scores; relative to an ECI score of 0, ECI scores of 1 to 2, 3 to 4, and 5 or greater were associated with odds ratios of 5.31 (P = .006), 8.12 (P < .001), and 12.84 (P < .001), respectively. Ninety-day complications occurred in 1.5% of the total cohort, and the incidence was not statistically different between sexes. Overall, 2-year secondary surgery rates were similar between male and female patients (5.1% and 6.7%, respectively; P = .4). CONCLUSIONS Female patients undergoing the Latarjet procedure for recurrent shoulder instability showed similar 90-day complication and 2-year secondary surgery rates to a matched cohort of male patients. Female sex, along with ECI score, however, was associated with a greater rate of 30-day ED visits. LEVEL OF EVIDENCE Level III, retrospective comparative case series.

Abstract
INTRODUCTION Lumbar laminotomy/diskectomy is a common procedure performed to address radiculopathy that persists despite conservative treatment. Understanding cost/reimbursement variability and its drivers has the potential to help optimize related healthcare delivery. The goal of this study was to assess variability and factors associated with reimbursement through 90 days after single-level lumbar laminotomy/diskectomy. METHODS Lumbar laminotomies/diskectomies were isolated from the 2010 to 2021 PearlDiver M151 data set. Exclusion criteria included patients younger than 18 years; other concomitant spinal procedures; and indications of trauma, oncologic, or infectious diagnoses. Patient, surgical, and perioperative data were abstracted. These variables were examined using a multivariable linear regression model with Bonferroni correction to determine factors independently correlated with reimbursement. RESULTS A total of 28,621 laminotomies/diskectomies were identified. The average ± standard deviation 90-day postoperative reimbursement was $9,453.83 ± 19,343.99 and, with a non-normal distribution, the median (inner quartile range) was $3,314 ($5,460). By multivariable linear regression, variables associated with greatest increase in 90-day postoperative reimbursement were associated with admission (with the index procedure [+$11,757.31] or readmission [+$31,248.80]), followed by insurance type (relative to Medicare, commercial +$4,183.79), postoperative adverse events (+$2,006.60), and postoperative emergency department visits (+$1,686.89) ( P < 0.0001 for each). Lesser associations were with Elixhauser Comorbidity Index (+$286.67 for each point increase) and age (-$24.65 with each year increase) ( P < 0.001 and P = 0.003, respectively). DISCUSSION This study assessed a large cohort of lumbar laminotomies/diskectomies and found substantial variations in reimbursement/cost to the healthcare system. The largest increase in reimbursement was associated with admission (with the index procedure or readmission), followed by insurance type, postoperative adverse events, and postoperative emergency department visits. These results highlight the need to balance inpatient versus outpatient surgeries while limiting postoperative readmissions to minimize the costs associated with healthcare delivery.

Abstract
BACKGROUND Von Willebrand disease (VWD) is the most common congenital bleeding disorder. This autosomal dominant condition arises from quantitative or qualitative defects of Von Willebrand factor. To our knowledge, this study leveraged a national database to characterize the largest VWD cohort of total hip arthroplasty (THA) patients to date, assessing 90-day postoperative adverse events and 5-year revision-free survival. METHODS Adult patients who underwent primary THA for osteoarthritis were identified from January 2010 to October 2021 in a nationwide database. Patients who had and did not have VWD were matched (4:1) on age, sex, and Elixhauser Comorbidity Index and compared with multivariable logistic regression. Patients were then categorized based upon venous thromboembolism (VTE) chemoprophylaxis prescription patterns to compare bleeding and thrombotic adverse events. RESULTS Of 544,851 THA patients, VWD was identified in 309 patients (0.06%). The matched cohorts contained 1,221 patients who did not have VWD and 306 patients who have VWD. On multivariable analysis, VWD patients had increased odds of 90-day VTE (odds ratio [OR] = 1.86) and hematoma (OR = 3.40) (P < .05 for all). No difference in 5-year revision-free survival was found. The VWD patients receiving aspirin or no prescriptions had greater odds of VTE (OR = 2.39, P = .048). Those on other chemoprophylaxis agents had greater odds of hematoma (OR = 4.84, P = .006). CONCLUSIONS Patients with VWD undergoing THA had increased odds of 90-day VTE if using aspirin or no prescriptions, or hematoma if using other chemoprophylaxis. There is a delicate balancing act of clotting versus bleeding that must be considered in managing such patients, but it was reassuring that no difference in overall 5-year revision-free survival was found.

Abstract
Background Clinical trials are crucial to advance products and procedures related to the spine. ClinicalTrials.gov is an internet-based registry and results database that catalogs trial characteristics, such as intervention types, phase, randomization, and blinding. Sponsorship trends have not been specifically evaluated for spine-related clinical trials, nor have trial characteristics been compared among spine-related trials sponsored by institutions, industries, and federal agencies. The purpose of this cross-sectional analysis of spine-related clinical trials was to characterize the types and trends of sponsorship for spine-related clinical trials, and compare trial characteristics among trials sponsored by institutions, industries, and federal agencies. Methods ClinicalTrials.gov was queried for clinical trials started from the launch of ClinicalTrials.gov (February 29, 2000) through December 31, 2022, using the term "spine." Trial characteristics were abstracted, including start year, intervention type, phase, randomization, and blinding. Univariate and multivariate analyses were performed to determine associations between sponsorship type and other trial characteristics. Results A total of 4,484 clinical trials were identified, of which 78 trials were excluded due to incomplete reporting of trial registration data. From 2000 through 2022, the number of spine-related trials initiated annually markedly increased (from 21 to 453, representing an increase of 2,057%). This was predominantly driven by an increase in the number of institutionally sponsored trials. Relative to trials with institutional sponsorship, industry sponsorship was independently associated with different intervention types, phases of study, lack of randomization, and lack of blinding. Relative to trials with institutional sponsorship, federal sponsorship was independently associated with intervention type, and phase of study. Conclusions From 2000 through 2022, the number of spine-related clinical trials initiated annually markedly increased, driven by an increase in institutionally sponsored trials. Specific trial characteristics were more or less likely for industrially or federally sponsored trials relative to institutionally sponsored trials suggesting the types of clinical trials are shifting over time.

Abstract
Background Following decompression in anterior cervical discectomy and fusion (ACDF), reconstruction is typically done with structural allograft or a synthetic cage. Relative trends and factors associated with utilizing these implants have not been well characterized. Methods The PearlDiver 2011 to 2021 M157 database was used to identify adult patients undergoing 1- or 2-level ACDF. The incidence of structural allograft versus synthetic cage utilized was compared by year. Patient factors predictive of synthetic cage use as the structural interbody for ACDF were assessed with multivariable analysis. Further, the use of anterior plates was trended to provide a measure of usage of stand-alone devices (this comparison was made beginning with 2016 based on coding limitations). Results Of 173,833 isolated 1- or 2-level ACDF cases identified, structural allograft was used for 63,029 (36.3%) and synthetic cages were used for 110,804 (63.8%). The use of synthetic cages increased from 51.1% of cases in 2011 to 75.8% of cases in 2021 (p < 0.0001). Independent clinical predictors of synthetic cage use were: older age (odds ratio [OR] 1.02 per decade), female sex (OR 1.04), and greater ECI (OR 1.09 per 2-point increase).Independent non-clinical predictors of synthetic cage use were: geographic region (Northeast OR 1.11, South OR 1.85, and West 2.08, each relative to Midwest), and provider specialty (orthopedic OR 1.06 relative to neurosurgeons). There was an increase in the percent of synthetic cases without separately coded plate ("stand-alone" interbody cages: 21.7% in 2016 to 35.3% in 2021, p < 0.001). Conclusions The usage of synthetic cages in 1- and 2- level ACDF has increased relative to structural allograft between 2011 and 2021 in the United States and more recently the use of "stand-alone" synthetic cages has been on the rise. Non-clinical as well as clinical factors were associated with implant choice, suggesting room for more consistent care algorithms.

Abstract
BACKGROUND Core decompression is a minimally invasive joint-preserving approach for early-stage osteonecrosis. The rate at which core decompression patients require total hip arthroplasty (THA) and rates of perioperative adverse outcomes have not been well-characterized. METHODS Adult patients undergoing core decompression and/or THA with osteonecrosis of the femoral head were identified from the 2015 to 2021 Q3 PearlDiver M157 database. Those undergoing THA without or with antecedent core decompression were identified and matched 4:1 on age, sex, and Elixhauser Comorbidity Index. Postoperative 90-day adverse events were compared with multivariable analysis. Five-year rates of revision, dislocation, and periprosthetic fracture were compared by the Kaplan-Meier curve and log-rank tests. RESULTS Core decompressions were identified for 3,025 patients of whom 387 (12.8%) went on to THA within 5 years (64% within the first year). The median time from initial core decompression to THA was 252 days. For THA, 26,209 adults were identified and 387 had prior core decompression. After matching, there were 1,320 without core decompression and 339 with core decompression. No statistically significant differences were observed in 90-day postoperative adverse events or 5-year rates of revision, dislocation, or periprosthetic fracture. CONCLUSION Core decompression may be an option for patients with osteonecrosis and does not seem to affect THA outcomes if required later.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVES Gabapentinoids have been increasingly studied as a non-narcotic option for neuropathic and postoperative pain. However, there is evidence suggesting that off-label use of these medications for the treatment of isolated LBP is not effective. The purpose of the current study was to evaluate prescription patterns for gabapentinoids among patients with isolated low back pain. METHODS Adult patients with LBP were abstracted from the 2019 M91Ortho PearlDiver dataset using International Classification of Diseases (ICD-10) code M54.5. Patients were excluded if they had a diagnosis of neurologic symptoms, history of spinal surgery, spinal fracture, or conditions for which gabapentinoids are FDA approved. Gabapentinoid and narcotic prescriptions within one year of LBP diagnosis were identified. Patient characteristics and prescriber specialty were extracted from the dataset and predictors of gabapentinoid prescriptions were determined using univariate and multivariate analyses. RESULTS Among the 1,158,875 isolated LBP patients, gabapentinoids were prescribed for 11%, narcotics for 8%, and both for 3%. The most common prescriber specialties included: primary care physicians (45%), nurse practitioners (15%), and pain management physicians (5%). Independent predictors of gabapentinoid prescriptions included: female sex, region of the country, and insurance type (P-values <.001). CONCLUSIONS Of nearly 1.2 million patients with isolated LBP, 14.2% were prescribed gabapentinoids within one year of their LBP diagnosis. Patient characteristics predictive of receiving gabapentinoids were predominantly non-clinical factors.

Abstract
OBJECTIVES Over the years, medical schools have evolved their curricula in response to the medical field, faculty, and students. The current study aims to examine how medical students study, what resources they most commonly use, and how it relates to United States Medical Licensing Examination (USMLE) Step 1 scores. METHODS A cross-sectional survey study of United States medical students was distributed via social media, GroupMe school chats, and school listservs from September 8, 2020, to December 12, 2020. The survey gathered data including, demographic and school information, resources students, time spent using each resource, and USMLE Step 1 scores. RESULTS The survey was completed by 560 students from 102 different United States medical schools. Study guides as online resources (83.2%) were mostly used, lecture (82.5%), Anki (spaced repetition flashcards, 68.3%), and school-organized sessions (workshops, labs, and small groups) (60.7%). Of the students surveyed, 90% attended schools with a recorded lecture option. Only 54% of these students watched their lectures live. When watched online, the average watching speed was 1.75 ± 0.4× with a mode of 2× speed. In examining different medical school styles, schools with a 1.5-year preclinical curriculum had higher USMLE Step 1 scores (244.5 ± 15.6 vs 236.9 ± 16.2, P-score = .024) compared to schools that did not (1- or 2-year preclinical curriculum). CONCLUSION Medical students seem to be using third-party resources in addition to their medical school curriculums. Because students are already broadly using these, medical schools could allow their curriculums to reference, require, or complement third-party online resources. Additionally, because of their increased cost, medical schools could consider ways to alleviate the cost on medical students as a means of equitable support. Lastly, Step 1 scores significantly correlated with schools with a 1.5-year preclinical curriculum, although the exact reasoning for this remains uncertain.

Abstract
Background Optimal management after posterior cruciate ligament (PCL) injury remains an active area of research, as reconstruction is technically challenging and poses unique risks in the posterior knee. Studies have reported variable rates of complications. Purpose To describe the rates of readmission, emergency department (ED) visits, and postoperative complications within 90 days of isolated PCL reconstruction (PCLR) in a large, national cohort to better understand the perioperative variables that influence a practitioner's decision of whether to pursue operative versus nonoperative management. Study Design Descriptive epidemiology study. Methods PCLRs from January 1, 2010, through August 31, 2020, were identified in PearlDiver, a national administrative database. Patients with concomitant ligament surgery and those with fewer than 90 days of postoperative database activity were excluded. Deep vein thromboses, pulmonary embolisms, surgical site infections, compartment syndrome, and vascular events within 90 days of surgery were identified, as were 90-day readmissions and ED visits. Logistic regression models were built in PearlDiver to calculate odds ratios (ORs) for ED utilization. Results The final cohort consisted of 1154 patients with isolated PCLR (mean age, 34 ± 16 years; 62% male). Most patients were located in the Southern United States (n = 417; 36.1%), and most had commercial insurance (n = 992; 86%). The 90-day rates of adverse events were as follows: deep vein thrombosis (13; 1.1%), pulmonary embolism (19; 1.6%), surgical site infection (<11; <1%), compartment syndrome (<11; <1%), vascular event (<11; <1%), readmission (13, 1.1%), and ED utilization (99; 8.6%). The majority of emergency department visits (52%) occurred in the first 2 weeks postoperatively. Predictive factors for ED utilization included Elixhauser Comorbidity Index score (OR = 1.31 per 2-point increase) and Medicaid insurance (OR = 2.03 relative to commercial insurance). Conclusion The current study reported rates of adverse events after isolated PCLR in a large, national cohort. The results provide important context for decisions about optimal management of PCL injury.

Abstract
INTRODUCTION The effect of orthopaedic fellowship subspecialization on surgical complications for patients with supracondylar fracture is unknown. This study seeks to compare the effect of subspecialty training on supracondylar fracture complications. METHODS The American Board of Orthopaedic Surgery Part II Examination Case List database was reviewed for all supracondylar fractures from 1999 to 2016. Procedures were divided by fellowship subspecialty (trauma, pediatric, or other) and case volume and assessed by surgeon-reported surgical complications. Predictive factors of complications were analyzed using a binary multivariate logistic regression. RESULTS Of 10,961 supracondylar fractures identified, 53.47% were done by pediatric fellowship-trained surgeons. Pediatric-trained surgeons had fewer surgical complications compared with their trauma or other trained peers (4.54%, 5.67%, and 6.24%; P = 0.001). Treatment by pediatric-trained surgeons reduced surgical complications (OR = 0.79, 95% CI: 0.66 to 0.94; P = 0.010), whereas increased case volume (31+ cases) showed no significant effect (OR = 0.79, 95% CI: 0.62 to 1.02; P = 0.068). Patient sex, age, and year of procedure did not affect complication rates, while those treated in the Southeast region of the United States and those with a complex fracture type were at increased odds. DISCUSSION Treatment of supracondylar fractures by pediatric-trained surgeons demonstrates reduced surgeon-reported complications compared with their other fellowship-trained counterparts, whereas case volume does not. This suggests the value of fellowship training beyond pertinent surgical caseload among pediatric-trained surgeons and may lie in targeted education efforts.

Abstract
INTRODUCTION Sponsorship trends have not been specifically evaluated for shoulder and elbow clinical trials, nor have trial characteristics been compared among shoulder and elbow trials sponsored by institutions, industries, and federal agencies. METHODS ClinicalTrials.gov was queried for clinical trials using the terms 'shoulder' and 'elbow.' Trial characteristics were abstracted, including start year, intervention type, phase, randomization, and blinding. Univariate and multivariate analyses were performed to determine associations between sponsorship type and other trial characteristics. RESULTS In total, 4,945 shoulder clinical trials and 1,517 elbow clinical trials were identified, of which 26 shoulder clinical trials and seven elbow clinical trials were excluded due to incomplete data. From 2000 to 2022, the number of shoulder and elbow trials initiated annually markedly increased driven by an increase in the number of institutional trials. Relative to trials with institutional sponsorship, industry sponsorship was independently associated with different intervention types, phase of study, lack of randomization, and blinding. DISCUSSION From 2000 to 2022, the number of shoulder and elbow clinical trials initiated annually markedly increased, driven by an increase in institutionally sponsored trials. For clinical trials related to the shoulder, design characteristics were found to differ based on study sponsorship type. This suggests that the design characteristics of shoulder-related clinical trials are shifting over time.

Abstract
INTRODUCTION Clavicle fractures are common and have historically been managed nonsurgically. Over time, there are increasing surgical considerations for such injuries. Nonetheless, trends over the past decade are not well characterized. METHODS Adult patients presenting for first diagnosis of clavicle fractures were identified from the 2010 to 2020 PearlDiver M151 database. Patients were defined to have undergone surgical management if they received clavicular open reduction and internal fixation within 90 days after fracture diagnosis. Patient age, sex, Elixhauser Comorbidity Index (ECI), geographic region, insurance coverage, fracture anatomic location, and polytraumatic diagnoses were extracted. Factors independently associated with surgical management versus nonsurgical management were assessed with multivariable analysis. RESULTS Overall, 50,980 patients with clavicle fractures were identified of whom 6,193 (12.1%) were managed surgically. This proportion increased significantly over the study period (7.4% in 2015 to 13.9% in 2020, P < 0.001). Independent predictors of surgical management included fracture diagnosis in 2020 (versus 2015, odds ratio [OR] 2.36), anatomic location (relative to lateral end, shaft OR 1.84 and sternal OR 3.35), and Midwest region of service (OR 1.26, relative to South) (P < 0.001 for all). DISCUSSION A small but increasing minority of patients with clavicle fractures are managed surgically. Clinical factors and nonclinical factors were associated with surgical management.

Abstract
BACKGROUND Patients with Down syndrome (DS) are being considered for total joint arthroplasty. There is limited literature regarding outcomes of patients with DS after total hip arthroplasty (THA) and total knee arthroplasty (TKA). METHODS Data were abstracted from the 2010 to 2021 Q1 PearlDiver M151 database. THA and TKA osteoarthritis adult patients with and without DS were identified. Patients were matched 1:10. Ninety-day postoperative events and 2-year revision rates were compared. RESULTS For THA, 154 patients with DS were matched with 1,532 patients without DS. For TKA, 150 patients with DS were matched with 1,495 patients without DS. On multivariable logistic regression, THA and TKA patients with DS were at markedly greater odds of postoperative events including any adverse event, sepsis, minor adverse event, urinary tract infection (UTI), acute kidney injury (AKI), and pneumonia. For both THA and TKA, 2-year revision rates were not increased for those with DS. DISCUSSION This study represents the largest cohorts for matched patients with DS undergoing THA or TKA through 90 days postoperatively. For both procedures, DS patients were found to have greater risk of several adverse events, but not 2-year revisions. These findings may help guide perioperative risk assessment, patient/family counseling, and care pathways.

Abstract
OBJECTIVES The purpose of this study was to compare the rates of secondary knee surgery for patients undergoing meniscus repair with or without concurrent anterior cruciate ligament reconstruction (ACLr). METHODS Utilizing a large national database, patients with meniscal repair with or without concurrent arthroscopic ACLr were identified. The two cohorts were then queried for secondary surgical procedures of the knee within the following 2 years. Frequency, age distribution, rates of secondary surgery, and type of secondary procedures performed were compared. RESULTS In total, 1,585 patients were identified: meniscus repair with ACLr was performed for 1,006 (63.5%) and isolated meniscal repair was performed for 579 (36.5%). Minimum of two year follow up was present for 487 (30.7% of the overall study population). Secondary surgery rates were not significantly different between meniscus repair with concurrent ACLr and isolated meniscus repairs with an overall mean follow up of 13 years (1.5-24 years) (10.6% vs. 13.6%, p = 0.126). For the 2 year follow up cohort, secondary surgery rates were not significantly different (19.3% vs. 25.6%, p = 0.1098). There were no differences in survivorship patterns between the two procedures, both in the larger cohort (p = 0.2016), and the cohort with minimum 2-year follow-up (p = 0.0586). CONCLUSION The current study assessed secondary surgery rates in patients undergoing meniscus repair with or without concurrent ACLr in a large patient database. Based on this data, no significant difference in rates of secondary knee surgery was identified.

Abstract
BACKGROUND Marfan syndrome is a rare inherited connective tissue disease, which may be present in patients who have advanced hip pathologies that may require total hip arthroplasty (THA). The postoperative course of patients who have Marfan syndrome following THA has not yet been defined. METHODS Adult patients who have and do not have Marfan syndrome and underwent THA were identified in a national database. Patients diagnosed who had infection, trauma, or neoplasms within the 90 days prior to surgery were excluded. Those who have versus those who did not have Marfan syndrome were matched 1:10 based on age, sex, and a comorbidity index. After matching, 144 patients who have Marfan syndrome and 1,440 who do not have Marfan syndrome were identified. The 90-day postoperative adverse events and 5-year revisions were assessed and compared with multivariable analyses and log rank tests, respectively. RESULTS Multivariable analyses demonstrated that Marfan syndrome was independently associated with greater odds of 90-day adverse events: venous thromboembolic events (odds ratio [OR]: 2.9, P = .001), cardiac events (OR: 4.5, P = .034), pneumonia (OR: 3.5, P < .001), and urinary tract infections (OR: 5.2, P < .001). There was no significant difference in 5-year rates of revision. CONCLUSIONS Following THA, Marfan syndrome was independently associated with greater rates of several 90-day adverse events, but not higher 5-year rates of revision. The identified at-risk adverse events may help guide surgeons to improve perioperative care pathways, while having confidence regarding joint survival of THA in this rare disease population.

Abstract
STUDY DESIGN Descriptive epidemiologic study. OBJECTIVE To analyze trends and patient characteristics of those undergoing cervicothoracic transforaminal, interlaminar, and facet injections over time. BACKGROUND Cervicothoracic transforaminal, interlaminar, and facet injections are considered for varied spinal pathologies. Evolving literature, changing physician preferences, insurance reimbursement policies, and patient factors may influence the utilization of such injections over time. METHODS Patients undergoing cervicothoracic transforaminal, interlaminar, and facet injections 2010-2020 were identified in the M151Ortho PearlDiver database using Current Procedural Terminology coding. Patient age, sex, Elixhauser Comorbidity Index, insurance plan (commercial, Medicaid, Medicare), and region of the country where the procedure was performed (Midwest, Northeast, South, and West) were extracted and assessed over study intervals based on prevalence per 100,000 covered lives. RESULTS Cervicothoracic transforaminal, interlaminar, and facet injections were identified for 195,221 (11.3%), 951,191 (55.2%), and 575,228 (33.4%) patients, respectively. Patient characteristics for each injection type were defined. The annual number of injections performed per 100,000 covered lives decreased during the study period for transforaminal (17.1% decrease) and interlaminar (9.3% decrease) but increased for facet (3.7% increase) injections (P<0.0001 for each). Stratifying by patient insurance type, administration of transforaminal, interlaminar, and facet injections per 100,000 covered lives was proportionally greatest for commercially insured patients (55%, 50%, and 45%, respectively), and proportionally smallest for Medicaid patients (10%, 13%, and 13%, respectively). Anesthesiology physicians performed the most injections, followed by physical medicine and rehabilitation physicians, with both provider types most frequently performing interlaminar injections, followed by facet and transforaminal injections. CONCLUSION Annual cervicothoracic transforaminal and interlaminar injection utilization declined by 17.1% and 9.3% from 2010 to 2020, whereas facet injection administration increased by 3.7% over the same interval. Evolving practice patterns are important to consider in characterizing the overall landscape of spine care.

Abstract
BACKGROUND Socioeconomic disparities in musculoskeletal care are increasingly recognized, however, no studies to date have investigated the role of the insurance carrier on outcomes after posterior spinal fusion (PSF) with segmental spinal instrumentation for adolescent idiopathic scoliosis (AIS). METHODS A US insurance dataset was queried using the PearlDiver Mariner software for all patients aged 10 to 18 undergoing PSF for a primary diagnosis of AIS between 2010 and 2020. Age, sex, geographic region, number of levels fused, and baseline medical comorbidities were queried. Complications occurring within 90 days of the index surgery were queried using the International Classification of Diseases, Ninth Revision (ICD-9) and International Classification of Diseases, 10th Revision (ICD-10) codes. Revision surgery was also queried up to 5 years after the index PSF. Categorical variables were compared using the Fisher χ 2 tests and continuous variables were compared using independent t tests. All-cause revision within 5 years was compared using the Kaplan-Meier analysis and a log-rank test. Significance was set at P -value <0.05. RESULTS A total of 10,794 patients were identified with 9006 (83.4%) patients with private insurance and 1788 (16.6%) patients insured by Medicaid. The mean follow-up in the database was 5.36±3 years for patients with private insurance and 4.78±2.9 years for patients with Medicaid insurance ( P <0.001). Children with AIS and Medicaid insurance had a significantly higher prevalence of asthma, hypertension, and obesity. A larger percentage of children with Medicaid insurance (41.3%) underwent a ≥13-level PSF compared with privately insured children (34.5%) ( P <0.001). Medicaid patients did not experience higher odds of postoperative complications; in addition, revision surgeries occurred in 1.1% and 1.8% of patients with private insurance and Medicaid insurance, respectively at 5 years postoperatively ( P =0.223). CONCLUSION Despite worse baseline comorbidities and longer fusion constructs, AIS patients insured with Medicaid did not have higher rates of complications or revisions at 5-year follow-up versus privately insured patients. LEVEL OF EVIDENCE Level III-retrospective cohort study.

BACKGROUND Readmissions are a typical postoperative metric; however, postoperative emergency department (ED) utilization also negatively affects patient care. Few studies have explored this metric after patellofemoral arthroplasty (PFA); thus, we investigated the incidence, timing, predictive factors, and reasons for ED utilization within 90 days after PFA. METHODS Using the 2010 to 2021 PearlDiver M151Ortho data set, a national billing claims database containing information of over 151 million US orthopaedic patients across all payer types, the study examined weekly ED visits up to 90 days after PFA and conducted univariate and multivariate analyses to identify predictive factors. RESULTS Of 7765 PFA patients, 11.2% (922) had ED visits within 90 days, with 46.7% (431) occurring in the first 3 weeks. Independent predictors of ED utilization included younger age (OR 1.40 per decade decrease), higher Elixhauser Comorbidity Index (OR 1.44 per 2-point increase), surgery in the South or Midwest (OR 1.27 and 1.31), and Medicaid insurance (OR 1.74). Postoperative pain accounted for 50.6% of visits. CONCLUSIONS 11.2% of PFA patients visited the ED within 90 days, primarily for postoperative pain. Younger, more comorbid, and Medicaid-insured patients were most likely to use the ED. This study suggests the need for targeted perioperative pain management to reduce ED utilization after PFA.

Abstract
BACKGROUND Total knee arthroplasty (TKA) is commonly considered to address symptomatically limiting knee osteoarthritis. With increasing utilization, understanding the variability and related drivers may help the healthcare system optimize delivery to the large numbers of patient to whom it is offered. METHODS A total of 1,066,327 TKA patients who underwent primary TKA were isolated from a 2010 to 2021 PearlDiver national dataset. Exclusion criteria included patients less than 18 years old and traumatic, infectious, or oncologic indications. Overall, 90-day reimbursements and variables associated with the patient, surgical procedure, region, and perioperative period were abstracted. Multivariable linear regressions were performed to determine independent drivers of reimbursement. RESULTS The 90-day postoperative reimbursements had an average (standard deviation) of $11,212.99 ($15,000.62), a median (interquartile range) of $4,472.00 ($13,101.00), and a total of $11,946,962,912. Variables independently associated with the greatest increase in overall 90-day reimbursement were related to admission (in-patient index-procedure [+$5,695.26] or hospital readmission [+$18,495.03]). Further drivers were region (Midwest +$8,826.21, West +$4,578.55, South +$3,709.40; relative to Northeast), insurance (commercial +$4,492.34, Medicaid +$1,187.65; relative to Medicare), postoperative emergency department visits (+$3,574.57), postoperative adverse events (+$1,309.35), (P < .0001 for each). CONCLUSION The current study assessed over a million TKA patients and found large variations in reimbursement/cost. The largest increases in reimbursement were associated with admission (readmission or index procedure). This was followed by region, insurance, and other postoperative events. These results underscore the necessity to balance performing out-patient surgeries in appropriate patients versus the risk of readmissions and defined other areas for cost containment strategies.

Abstract
BACKGROUND Following total hip arthroplasty (THA), readmissions and emergency department (ED) visits have been studied. Urgent care utilization is not well-characterized and may represent an overlooked avenue to facilitate lesser acuity patient needs. METHODS Primary THAs performed for osteoarthritis indications were identified from 2010 to April of 2021 from a large national database. The incidence and timing of 90-day postoperative ED and urgent care visits were determined. Univariable and multivariable analyses assessed factors associated with urgent care relative to ED utilization. Reasons and acuity of diagnoses for these visits were determined. For 213,189 THA patients, 90-day ED visits were identified for 37,692 (17.7%) and urgent care visits for 2,083 (1.0%). The greatest incidence of both ED and urgent care visits were in the first two postoperative weeks. RESULTS Independent predictors of urgent care utilization relative to ED utilization were: procedures being performed in the Northeast or South, insurance plan being Commercial, women, and lesser comorbidity burden (P < .0001). Reason for visits to the ED was directly related to the surgical site for 25.6% but for urgent care were just 4.8% (P < .0001). Reasons for visits to the ED were classified as low-acuity for 57.4% and for urgent care 96.9% (P < .0001). CONCLUSION Following THA, patients may need urgent evaluation. While many issues can be addressed through the office, urgent care visits may represent a viable and underused resource relative to the ED for a large percentage of patients who have lower acuity diagnoses.

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.

Abstract
STUDY DESIGN Descriptive epidemiologic study. OBJECTIVE To compare trends in utilization and predictive factors for single-level cervical disc arthroplasty (CDA) relative to anterior cervical discectomy and fusion (ACDF) over the years. BACKGROUND CDA is an alternative to ACDF for the treatment of cervical spine pathologies. With both procedures performed for similar indications, controversy on best practices exists. MATERIALS AND METHODS Patients who underwent single-level CDA or ACDF were identified in the 2010 through 2021 PearlDiver M151Ortho data set. The yearly number of CDAs performed and proportionality was assessed. Predictive patient factors for undergoing CDA as opposed to ACDF were determined. Kaplan Meyer survival analysis with an endpoint of cervical spine reoperation compared 5-year outcomes between CDA and ACDF. RESULTS From 2010 to 2021, 19,301 single-level CDAs and 181,476 single-level ACDFs were identified. The proportional utilization of CDA relative to ACDF increased from 4.00% in 2010 to 14.15% in 2018 ( P < 0.0001), after which there was a plateau between 2018 and 2021 where proportional utilization was 14.47% ( P = 0.4654). Multivariate analysis identified several predictors of undergoing CDA rather than ACDF, including: younger age [odds ratio (OR) per decade decrease: 1.72], having surgery performed in the Midwest, Northeast, or West (relative to South, OR: 1.16, 1.13, 2.26, respectively), having Commercial insurance (relative to Medicare, OR: 1.75), and having surgery performed by an orthopedic surgeon (relative to a neurological surgeon, OR: 1.54) ( P < 0.0001 for each). There was no statistically significant difference in 5-year survival to further cervical spine surgery between CDA and ACDF at 5 years (97.6% vs. 97.7%, P = 0.4249). CONCLUSIONS Although the use of CDA relative to ACDF rose from 2010 to 2018, its use has subsequently plateaued between 2018 and 2021 and remained a relatively low percentage of the single-level anterior cervical surgeries performed (14.47% in 2021). The causes for such changes in the trend are unclear.

Abstract
BACKGROUND CONTEXT Morbid obesity (MO) has been associated with increased risk of adverse events following procedures such as posterior lumbar fusion (PLF). While preemptive bariatric surgery (BS) has been considered for those with MO (body mass index [BMI] ≥35 kg/m2), not all undergoing such intervention have significant weight loss, and the impact of BS has been shown to correlate with weight loss after different related procedures. PURPOSE To examine outcomes following isolated single level PLF among patients with history of BS who subsequently did and did not transition out of the morbidly obese category. STUDY DESIGN/SETTING Retrospective case-control study. PATIENT SAMPLE The PearlDiver 2010-Q1 2020 MSpine database was used to identify adult patients undergoing elective isolated PLF. Patients were excluded if they had a history of infection, neoplasm, or trauma in the 90-days prior to their PLF and if they were not active in the database for at least 90 days following their surgery. Three sub-cohorts were defined: 1) MO controls without a history of BS (-BS+MO), 2) patients with prior BS procedure who remained MO (+BS+MO), and 3) patients with prior BS who were no longer MO at the time of PLF (+BS-MO). Matched 1:1:1 populations were created for these three sub-cohorts based on age, sex and Elixhauser Comorbidity Index (ECI). OUTCOME MEASURES Ninety-day adverse events and readmission rates were assessed and compared between the three sub-cohorts (-BS+MO, +BS+MO, +BS-MO). METHODS Univariable analyses and multivariable logistic regression were performed on the matched population to compare 90-day adverse events and readmission rates controlling for age, sex, and ECI. RESULTS The current study identified PLF patients who were MO at the time of surgery but did not have a history of BS (-BS+MO, n=34,236), those who had BS and remained MO (+BS+MO, n=564), and those who had MS and were no longer MO (+BS-MO, n=209 which was only 27% of those who had BS). On multivariable analysis of the matched populations, those that had BS but remained MO (+BS+MO) were not at reduced odds of 90-day adverse events. However, those that had BS and were no longer MO (+BS-MO) were at reduced odds of 90-day any, severe, and minor adverse events (OR 0.41, 0.51, and 0.37, respectively with p<0.05 for all). CONCLUSIONS Only 27% of those with a history of BS prior to PLF transitioned out of the MO category. Compared to those who were morbidly obese without BS, those who had BS were only at reduced risk of 90-day adverse events if they actually lost weight sufficient to drop out of morbidly obesity. These findings should be taken into account when counseling patients and interpreting prior studies.

Abstract
BACKGROUND CONTEXT Lumbar discectomy is a common procedure following which emergency department (ED) visits may occur. Although many quality improvement initiatives target reemissions, ED visits may be more common, be a marker of quality of care, affect patient satisfaction, and contribute to health-care resource utilization and costs. PURPOSE To analyze the timing and risk factors predicting ED utilization following lumbar discectomy and thereby facilitate better-targeted risk reduction. STUDY DESIGN/SETTING Retrospective database review of the 2010 to April 30th, 2021, M157Ortho PearlDiver dataset. PATIENT SAMPLE Single-level lumbar laminotomy/discectomy between 2010 and April 30th, 2021, in the PearlDiver M157Ortho dataset. OUTCOME MEASURES Functional measures-ED utilization in the 90 days following lumbar discectomy, patient-level predictors for ED utilization, and number and type of reoperations performed in the 90 days following lumbar discectomy. METHODS Lumbar laminotomies/discectomies were identified. Patients were excluded if additional procedures were performed or if there was not 90-day follow-up in the dataset. Patient factors were extracted, including age, sex, Elixhauser comorbidity index (ECI), region of the country in which their procedure was performed (Midwest, Northeast, South, West), and patient insurance plan (Commercial, Medicaid, Medicare). The incidence, timing, and frequency of ED utilization within 90 days of lumbar discectomy were then determined. Cohort average weekly ED utilization at 1-year postoperatively was calculated as a baseline for reference. Patient factors predictive of postoperative ED utilization were then determined with univariate and multivariate analyses. Primary diagnoses for ED visits were also categorized. Patients who underwent reoperation for complications related to lumbar discectomy following ED visits were determined, and types of reoperation procedures were characterized. RESULTS Of 281,103 lumbar discectomy patients identified, ED visits within 90 days of surgery were identified for 28,632 (10.2%). Of note, 40.4% of these ED visits occurred in the first 2 postoperative weeks. Multivariate analysis revealed several independent predictors of ED utilization following lumbar discectomy, including: younger age (odds ratio [OR] 1.21 per decade decrease), female sex (OR 1.12 relative to male), higher ECI (OR 1.42 per 2-point increase), having surgery performed in the Northeast, Midwest, or West United States (OR 1.05, 1.17, and 1.13, respectively, relative to South), and Medicaid coverage (OR 1.89 relative to Medicare). Forty-three percent of ED visits were surgical site related, of which surgical site pain predominated at 34.2% of overall reasons. Of patients who visited the ED, 943 (3.3%) underwent reoperation in the subsequent 2 weeks. Laminectomy with nerve root decompression was the most performed reoperation (30.9%), followed by incision and drainage (22.5%), posterior nonsegmental instrumentation (10.3%), laminectomy facetectomy and foraminotomy (9.97%), repair of dural/CSF leak or pseudomeningocele with laminectomy (9.3%), repair of dural/CSF leak not requiring laminectomy (8.9%), arthrodesis (4.3%), and posterior segmental instrumentation (3.9%). CONCLUSIONS Following lumbar discectomy, over 1 in 10 patients were found to visit the ED in the 90 days following their surgery, most commonly in the first 2 postoperative weeks. Specific patient characteristics were associated with such ED visits, with the most common primary diagnoses among ED visitors being surgical site pain. About 3.3% of patients who visited the ED underwent reoperation in the subsequent 2 weeks. Through identification of the timing, risk factors, primary reasons for, and risk of reoperation following ED utilization in the 90-day period after lumbar discectomy, care pathways can be modified to improve patient satisfaction, outcomes, and reduce excess health-care expenditures.

Abstract
BACKGROUND Ankle fractures are common orthopaedic injuries that may be indicated for open reduction internal fixation (ORIF). Although the negative impact of tobacco use on perioperative outcomes of ankle fracture ORIF has been described, the potential impact of cannabis use on related outcomes is not as well established. METHODS Retrospective database study of adult patients undergoing ankle ORIF for closed, isolated, ankle fractures from the 2010-2021 Q1 PearlDiver M151 data set. Subcohorts without and with cannabis and/or tobacco use were identified based on coding and matched based on patient age, sex, and Elixhauser Comorbidity Index (ECI) scores to yield groups of nonusers, tobacco users, tobacco and cannabis users, and cannabis users. Ninety-day adverse events were assessed between matched subcohorts with multivariable logistic regression controlling for age, sex, and ECI. RESULTS A total of 149 289 patients met study inclusion criteria for whom tobacco only use was documented for 14 989 (10.0%), tobacco and cannabis use for 2726 (1.8%), and cannabis only use for 867 (0.6%). Matching yielded 823 for each group. On multivariable analyses, isolated tobacco users were at higher odds of 90-day urinary tract infections (UTIs) (odds ratio [OR] 2.64), minor adverse events (OR 2.33), all-cause adverse events (OR 2.17), readmissions (OR 1.85), and severe adverse events (OR 1.84). Tobacco and cannabis comorbid users were at a marginally higher odds of 90-day UTI (OR 2.82), minor adverse events (OR 2.51), readmissions (OR 2.39), and any adverse events (OR 2.22). Cannabis only users were not at greater odds of 90-day adverse events relative to nonusers. CONCLUSION Patients with tobacco use (alone or with cannabis) were at greater odds of 90-day adverse events following ankle fracture ORIF, but cannabis only users were not. LEVEL OF EVIDENCE Level III, Retrospective database study.

Abstract
BACKGROUND As racial/ethnic disparities in management of distal radius fractures (DRFs) have not been well elucidated in the literature, this study sought to evaluate the correlation of race/ethnicity on surgical versus nonsurgical management of DRFs in a Medicare population. METHODS The PearlDiver Standard Analytical Files Medicare claims database was used to identify patients ≥65 years old with isolated DRF. Patients with polytrauma or surgery performed for upper extremity neoplasm were excluded. Surgical versus nonsurgical management was compared based on demographics, comorbidity (Elixhauser Comorbidity Index, ECI), race/ethnicity, and whether the fracture was open or closed. Univariate and multivariable analyses were used to assess for independent predictors. RESULTS Of 54 564 isolated DRFs identified, surgery was performed for 20 663 (37.9%). On multivariable analysis, patients were independently less likely to receive surgical management if they were: older (relative to 65- to 69-year-olds, incrementally decreasing by age bracket up to >85 years where odds ratio [OR] was 0.27, P < .001), higher ECI (per 2 increase OR: 0.96, P < .001), and closed fractures (OR: 0.35, P < .001). For race/ethnicity: black (OR: 0.64, P < .001), Hispanic (OR: 0.71, P < .001), and Asian (OR: 0.60, P < .001) patients were less likely to undergo surgery. CONCLUSIONS While age, comorbidities, and fracture type are known to affect surgical decision-making for DRF, race/ethnicity has not previously been reported, and its independent prediction of nonsurgical management for several groups points to a disparity in surgical decision-making/access to care. This highlights the need for increased attention to initiatives that seek to provide equitable care to all patients. LEVEL OF EVIDENCE Level III-Retrospective review of national database.

Abstract
INTRODUCTION Foot and ankle fractures are common injuries for which patients may need urgent evaluation and care. Many such injuries are managed in emergency departments (EDs), but urgent care facilities may sometimes be an appropriate setting. Understanding which foot and ankle fractures are managed at which facility might help define care algorithms, improve patient experience, and suggest directions for containing costs. METHODS This retrospective cohort study used the 2010 to 2020 M151 PearlDiver administrative database. Adult patients less than 65 years old presenting to EDs and urgent care facilities for foot and ankle fractures were identified using ICD-9 and ICD-10 diagnosis codes, excluding polytrauma, and Medicare patients. Patient/injury variables associated with urgent care utilization relative to ED utilization and utilization trends of urgent care relative to ED were assessed with univariable and multivariable analyses. RESULTS From 2010 to 2020, 1,120,422 patients with isolated foot and ankle fractures presented to EDs and urgent care facilities. Urgent care visits evolved from 2.2% in 2010 to 4.4% in 2020 (P , 0.0001). Independent predictors of urgent care relative to ED utilization were defined. In decreasing odds ratios (ORs), these were insurance (relative to Medicaid, commercial OR 8.03), geographic region (relative to Midwest, Northeast OR 3.55, South OR 1.74, West OR 1.06), anatomic location of fracture (relative to ankle, forefoot OR 3.45, midfoot 2.20, hindfoot 1.63), closed fracture (OR 2.20), female sex (OR 1.29), lower ECI (OR 1.11 per unit decrease), and younger age (OR 1.08 per decade decrease) (P , 0.0001 for all). DISCUSSION A small but increasing minority of patients with foot and ankle fractures are managed in urgent care facilities relative to EDs. While patients with certain injury types were associated with increased odds of urgent care relative to ED utilization, the greatest predictors were nonclinical, such as geographic regions and insurance type, suggesting areas for optimizing access to certain care pathways.

Abstract
STUDY DESIGN A retrospective cohort study using the 2010-2020 MSpine PearlDiver administrative data set. OBJECTIVE To compare perioperative adverse events and five-year revisions for single-level anterior cervical discectomy and fusion (ACDF) versus posterior cervical foraminotomy (PCF). SUMMARY OF BACKGROUND DATA Cervical disk disease can often be treated surgically using single-level ACDF or PCF. Prior studies have suggested that posterior approaches provide similar short-term outcomes as ACDF; however, posterior procedures may have an increased risk of revision surgery. MATERIALS AND METHODS The database was queried for patients undergoing elective single-level ACDF or PCF (excluding cases performed for myelopathy, trauma, neoplasm, and/or infection). Outcomes, including specific complications, readmission, and reoperations, were assessed. Multivariable logistic regression was used to ascertain odds ratios (OR) of 90-day adverse events controlling for age, sex, and comorbidities. Kaplan-Meier survival analysis was performed to determine five-year rates of cervical reoperation in the ACDF and PCF cohorts. RESULTS A total of 31,953 patients treated by ACDF (29,958, 93.76%) or PCF (1995, 6.24%) were identified. Multivariable analysis, controlling for age, sex, and comorbidities, demonstrated that PCF was associated with significantly greater odds of aggregated serious adverse events (OR 2.17, P <0.001), wound dehiscence (OR 5.89, P <0.001), surgical site infection (OR 3.66, P <0.001), and pulmonary embolism (OR 1.72, P =0.04). However, PCF was associated with significantly lower odds of readmission (OR 0.32, P <0.001), dysphagia (OR 0.44, P <0.001), and pneumonia (OR 0.50, P =0.004). At five years, PCF cases had a significantly higher cumulative revision rate compared with ACDF cases (19.0% vs. 14.8%, P <0.001). CONCLUSIONS The current study is the largest to date to compare short-term adverse events and five-year revision rates between single-level ACDF and PCF for nonmyelopathy elective cases. Perioperative adverse events differed by procedure, and it was notable that the incidence of cumulative revisions was higher for PCF. These findings can be used in decision-making when there is clinical equipoise between ACDF and PCF.

Abstract
Background Ice skating, inline skating, and roller skating are popular sports in the United States (US). Although they are similar, injuries incurred may be distinct and may have evolved over time. Purpose To characterize injuries related to ice skating, inline skating, and roller skating and track injury patterns over a 20-year period. Study Design Descriptive epidemiology study. Methods The current study utilized the National Electronic Injury Surveillance System, a database reporting consumer product-related injuries seen at emergency departments in the US. All ice skating, inline skating, and roller skating injuries between 2002 and 2021 were identified, and patient demographics, types of injury, and year of injury were compared between skating types. Results A total of 1,656,746 skating-related injuries were estimated nationally: 24% (403,791) for ice skating, 24% (400,172) for inline skating, and 52% (852,783) for roller skating. While the incidence of ice-skating- and roller-skating-related injuries decreased by 34.4% (from 22,490 in 2002-2004 to 14,758 in 2019-2021) and 29.6% (from 42,452 in 2002-2004 to 31,980 in 2019-2021), respectively, injuries related to inline skating decreased comparatively more, by 75.8% over the study period (from 48,097 in 2002-2004 to 11,662 in 2019-2021). Injuries occurred predominantly to the head/face/neck for ice skating (n = 139,501; 34.5% of injuries), whereas injuries occurred predominantly in the shoulder/arm/elbow/wrist for inline skating (n = 212,088, 53.0% of injuries) and roller skating (n = 425,216, 49.9% of injuries). Fracture was the most common injury type for all 3 skating types (n = 614,853, 37.1% of injuries), and the majority of fractures occurred in the upper extremity (shoulder/arm/elbow/wrist) for all 3 skating types (n = 59,624, 60.0% [ice skating]; n = 69,197, 41.2% [inline skating], and n = 237,099, 68.2% [roller skating]). Lower extremity (leg/knee/ankle) fractures were more common among ice skating (n = 28,019, 28.2%) and roller skating (n = 82,094, 23.6%) injuries compared with inline skating (n = 21,391, 12.7%). Conclusion In the current study, we found that fractures were the most common type of injury regardless of skating type but that the location of the injury/fracture varied by skating type.

Abstract
BACKGROUND Spinal fusion is a common procedure for which bone grafting is a critical component. Although iliac crest (separate incision autograft) is typically referred to as the "gold standard" grafting material, it seems to be used less and less frequently. METHODS The 2010 to Q3 2020 MSpine PearlDiver data set was used to identify patients receiving separate incision autograft versus local autograft/allograft/graft supplement for spinal fusion. Grafting trends over the decade were determined. Patient age, sex, Elixhauser Comorbidity Index, smoking status, insurance plan, region of the country where the surgery was conducted, and surgeon specialty were characterized and compared by the type of bone graft using univariate and multivariate analyses. RESULTS Of 373,569 spinal bone grafting procedures, separate incision autografts were used for 32,401 (8.67%). A gradual decline was observed from 2010 (10.57% of spinal grafting procedures) to 2020 (4.69%, P -value < 0.00001). Independent predictors of having had a separate incision autograft in order of decreasing odds included surgeon specialty (relative to neurosurgery, orthopaedic odds ratio [OR], 2.45), smoking status (relative to nonsmokers, smokers OR, 1.45), region of the country (relative to Midwest, Northeast OR, 1.11; West OR, 1.42; and South OR, 1.48), insurance (relative to commercial, Medicare OR, 1.14), younger age (OR, 1.04 per decade increase), and lower Elixhauser Comorbidity Index (OR, 0.95 per two-point increase) ( P < 0.0001 for each). CONCLUSION Iliac crest autograft continues to be referred to as the gold standard grafting material for spine fusions. However, the use of this has faded over the past decade to only 4.69% of spinal fusions in 2020. While some patient factors had an effect on when separate incision autograft was used, nonsurgical factors, including surgeon specialty, geographic region where the surgery was conducted, and insurance factors, suggested that external factors/physician training influence this choice.

Abstract
BACKGROUND Office-based surgery can increase logistical and financial efficiency for patients and surgeons. The current study compares wide-awake office-based carpal tunnel release to wide-awake surgeries performed in the operating room (OR) in terms of volume, financial burden, narcotic prescriptions, and adverse events. METHODS Surgeries performed under local-only anesthesia from 2010 to 2020 were identified in a national administrative database (PearlDiver™). Patients were grouped by surgical setting and matched based on age, sex, comorbidity burden, and geographic region. Primary endpoints included total disbursement and physician reimbursement, as well as 30-day narcotics prescriptions, emergency department (ED) visits, and surgical site infections (SSI). RESULTS Before matching, there were 303,741 OR surgeries and 5,463 office surgeries. From 2010 to 2020, the percent of surgeries in the office increased from 1.2% to 3.4%. Matched cohorts included 21,835 OR surgeries and 5,459 office surgeries. Office surgery was associated with lower total disbursement and physician reimbursement for patients with commercial insurance, Medicaid, and Medicare. Linear regression modeling indicated that office-based surgery was significantly associated with lower total disbursement and physician reimbursement. Fewer office patients filled narcotic prescriptions and visited the ED, and there was no difference in SSI. CONCLUSION Compared to OR surgery, office surgery was associated with lower financial burden, fewer narcotics prescriptions and ED visits, and similar incidence of SSI. These findings, together with literature showing greater efficiency in the office, suggest that office-based surgeries are safe and cost-effective and should continue to grow.

Abstract
BACKGROUND Trigger finger release (TFR) has traditionally been performed in outpatient operating rooms. More recently, TFR may be performed in the office setting to achieve greater efficiency and cost savings. METHODS The 2010-2020 Q2 PearlDiver M91Ortho data set was analyzed for cases of TFR. Exclusion criteria were age less than 18 years, <30 days of postoperative records, concomitant hand surgery, monitored anesthesia use, and inpatient surgery. Age, sex, and Elixhauser comorbidity index were recorded. Operating room and office procedures were matched 4:1 based on patient characteristics. Total and physician reimbursement for the day of surgery, as well as 30-day narcotics prescriptions, emergency department (ED) visits, and surgical site infections (SSI) were determined. RESULTS Before matching, TFRs were found to be increasingly performed in the office (from 7.9% in 2010 to 14.6% in 2020). Matched cohorts consisted of 63,951 operating room and 15,992 office procedures. Office procedures had lower mean total reimbursements ($435 vs $752, P < 0.001), slightly lower mean physician reimbursements ($420 vs $460, P < 0.001), and lower rates of narcotic prescriptions (30.5% vs 50.5%, P < 0.001) and 30-day ED visits (2.2% vs 2.9%, P < 0.05). There was no difference in 30-day SSI (0.5% vs 0.6%, P = 0.374). CONCLUSIONS In-office TFR is becoming increasingly prevalent. After matching, in-office TFRs were associated with lesser costs to the system, lower narcotic prescriptions, and fewer postoperative ED visits, without increased SSI. Although it is important to perform procedures in the best location for the patient, physician, and system, the current study supports the increased value offered by in-office TFR.

Abstract
Multiple myeloma (MM) is a systemic disorder characterised by proliferation of B-lymphocytes and plasma cells in the bone marrow. The primary aims of the management of spinal lesions in MM are pain control and fracture stabilisation. Vertebral augmentation procedures (VAP) can be subdivided into percutaneous vertebroplasty (VP) and balloon kyphoplasty (BKP). BKP involves the placement of orthopaedic balloons into the fractured vertebral body, creating a void into which polymethylmethacrylate bone cement is injected. This review outlines the management of spinal lesions in patients with MM, with a focus on the comparative risks and efficacy of vertebroplasty (VP) and balloon kyphoplasty (BKP). Soft tissue masses in MM are highly radiosensitive. Bisphosphonates and newer oncological therapies have decreased the indications for palliative radiotherapy, while spinal bracing can be utilised in selected cases to provide stability. BKP and VP provide equivalent long term pain control after MM vertebral compression fractures (VCF). BKP is superior to non-operative management and VP for restoration of vertebral body height and prevention of segmental kyphosis. Current evidence suggests a greater degree of correction of kyphotic deformity and restoration of mid vertebral height (MVH) with BKP when compared with VP. The literature supports the use of BKP even in the presence of posterior vertebral body wall (PVBW) fractures, a group previously considered a contraindication to VAP. Superior functional outcomes have been reported in patients undergoing early versus delayed BKP (<6-8 weeks). Current evidence supports a lower risk of cement extrusion with BKP than with VP, but serious complications following VAP are rare. MM spinal pathology should be managed in a multidisciplinary setting. Surgical decompression and instrumentation are rarely indicated, due to the radio-sensitivity of soft tissue lesions in MM. BKP is a safe and effective procedure for VCF secondary to MM.

Abstract
During the past decade, US orthopedic residency graduates have become increasingly subspecialized presumably for decreased patient complications; however, no study has examined this clinical utility for foot and ankle (F&A) surgeries among different fellowship subspecialties. Data from American Board of Orthopaedic Surgery 1999 to 2016 Part II Board Certification Examinations were used to assess patients treated by F&A fellowship-trained, trauma fellowship-trained, and all other fellowship-trained orthopedic surgeons performing ankle fracture repair. Adverse events were compared by surgical complexity and fellowship status. Factors independently associated with surgical complications were identified using a binary multivariate logistic regression. A total of 45,031 F&A cases met inclusion criteria. From 1999 to 2016, the percentage of F&A procedures performed by F&A fellowship surgeons steadily increased. Surgical complications were significantly different between fellowship trainings (F&A, 7.23%; trauma, 6.65%; and other, 7.84%). This difference became more pronounced with more complicated fracture pattern. On multivariate regression, F&A fellowship training was associated with significantly decreased likelihood of surgeon-reported complications (odds ratio, 0.83; 95% CI, 0.76-0.92; P<.001), as was trauma fellowship training (odds ratio, 0.90; 95% CI, 0.81-0.99; P=.035). Despite presumed increased complexity of cases treated by F&A fellowship-trained surgeons, these patients had significantly decreased risk of surgeon-reported surgical complications, thus highlighting the value of F&A fellowship training. In the absence of vital patient comorbidity data in the American Board of Orthopaedic Surgery database, further research must examine specific patient comorbidities and case acuity and their influence on treatments and surgical complications between fellowship-trained and other orthopedic surgeons to further illuminate the value of subspecialty training.

Abstract
BACKGROUND Geriatric hip fractures are common and associated with high morbidity and mortality. This study aimed to evaluate the incidence, timing, and risk factors of contralateral hip fracture after initial hip fracture. METHODS Initial hip fractures in patients older than 65 years were abstracted from the national, administrative M91Ortho PearlDiver data set. Incidence and timing of contralateral hip fractures in the following 10 years were identified. Kaplan-Meier survival analysis until contralateral hip fracture was conducted. To account for patient mortality over the later years, 2-year univariate and multivariate analyses were used to determine factors predictive of contralateral hip fracture. RESULTS Of the initial 104,311 hip fractures identified, contralateral hip fracture in the 10 years that followed was identified for 7,186 (6.9%), of which 68.4% occurred in the first 2 years. Kaplan-Meier survival analysis until contralateral fracture revealed the 10-year incidence to be 12.9% when controlling for those lost from the data set during the study period. Multivariate logistic regression revealed independent predictors of contralateral hip fracture in the 2 years after index hip fracture, when the incidence was greatest, to be female sex (odds ratio [OR] 1.15), body mass index < 20 (OR 1.30), and percutaneous pinning surgery for initial hip fracture fixation (OR 1.58) (P < 0.0001 for each). CONCLUSIONS In a national cohort of 104,311 geriatric hip fractures, Kaplan-Meier analysis for contralateral hip fracture found the 10-year incidence to be 12.9%, of which nearly 70% were in the first 2 years, and predisposing factors were defined. As such, future research should aim to identify the cause and mitigate the risk of secondary contralateral hip fractures in geriatric patients.

Abstract
Background Total ankle replacement (TAR) surgery has increased in recent decades. The aim of this study was to investigate the evolving burden of revision surgery and risk factors and timing of revision or explant. Methods Using the 2010 to 2020 PearlDiver M151Ortho data set, this retrospective cohort study identified primary TAR, TAR revision, and TAR explant patients via Current Procedural Terminology (CPT) and International Classification of Disease Procedural (ICD-P) codes. This database contains billing claims information across all payers and sites of care in the United States. Patient factors investigated included age, sex, and Elixhauser Comorbidity Index (ECI). Annual incidence for primary TAR was normalized per 100 000 covered lives in the data set for each year of study and recorded. Annual incidence of revision TAR and explant were normalized per 100 TARs performed for each year of study. Multivariate logistic regression analyses were performed to determine independent risk factors for revision TAR or explant. For explants, the eventual intervention by 2 years was analyzed. Ten-year timing and survival to revision or explant surgery following unilateral TAR were characterized. Results A total of 10 531 primary, 1218 revision, and 1735 explant TARs were identified. After normalization, TAR utilization increased by 284% from 2010 to 2020, annual TAR revisions rose 28%, and annual TAR explants decreased 65%. Independent predictors of revision TAR were younger age (odds ratio [OR] 1.29 per decade decrease) and higher ECI (OR 1.23 per 2-point increase). Independent predictors of explant included younger age (OR 1.80 per decade decrease), female sex (OR 1.17), and higher ECI (OR 1.35 per 2-point increase). The 10-year implant survival rate was 91.8%, of which 73% of revisions and 83% of explants occurred in the first 3 years following index TAR. Conclusion TAR utilization has grown substantially over the past decade, with minimal increases in the annual rate of revision surgery with respect to index procedures performed.

Abstract
PURPOSE To evaluate 90-day complications, 5-year secondary surgery rates, and risk factors for secondary surgery following primary hip arthroscopy performed for femoroacetabular impingement and/or labral tears using a large national dataset. METHODS A retrospective analysis was conducted using the PearlDiver Mariner151 database. Patients with International Classification of Diseases, Tenth Revision, diagnosis codes for femoroacetabular impingement and/or labral tear undergoing primary hip arthroscopy with femoroplasty, acetabuloplasty, and/or labral repair between 2015 and 2021 were identified. Those with concomitant International Classification of Diseases, Tenth Revision, codes for infection, neoplasm, or fracture were excluded, as were patients with a history of previous hip arthroscopy or total hip arthroplasty, or age ≥70 years. Rates of complications within 90 days of surgery were assessed. Five-year rates of secondary surgery-revision hip arthroscopy or conversion to total hip arthroplasty-were determined by Kaplan-Meier analysis, and risk factors for secondary surgery were identified by multivariate logistic regression. RESULTS A total of 31,623 patients underwent primary hip arthroscopy from October 2015 to April 2021, with annual volumes ranging from 5,340 to 6,343 surgeries per year. Femoroplasty was the most frequent surgical procedure (performed in 81.1% of surgical encounters), followed by labral repair (72.6%) and acetabuloplasty (33.0%). Ninety-day postoperative complication rates were low, with 1.28% of patients experiencing any complication. The 5-year secondary surgery rate was 4.9% (N = 915 patients). Multivariate logistic regression identified age <20 years (odds ratio [OR] 1.50; P < .001), female sex (OR 1.33; P < .001), class I obesity (body mass index 30-34.9: OR 1.30; P = .04), and class II/III obesity (body mass index ≥35.0: OR 1.29; P = .02) as independent predictors of secondary surgery. CONCLUSIONS In this study of primary hip arthroscopy, 90-day adverse events were low at 1.28%, and the 5-year secondary surgery rate was 4.9%. Age younger than 20 years, female sex, and obesity were risk factors for secondary surgery, suggesting the need for increased surveillance in these patient groups.

Abstract
BACKGROUND CONTEXT Lumbar discectomy is a common procedure for which patients with rheumatoid arthritis (RA) may be considered. RA is an autoinflammatory disease that may predispose patients to postoperative adverse outcomes. PURPOSE To assess the relative odds of adverse events after lumbar discectomy for those with versus without RA in a large, national, administrative dataset. STUDY DESIGN/SETTING Retrospective cohort study using the 2010 to 2020 MSpine PearlDiver dataset. PATIENT SAMPLE After exclusion of patients under 18 years old, those with any trauma, neoplasm, or infection diagnosis within the month before lumbar discectomy, and any patients who had any alternative lumbar spinal surgery performed on the same day as lumbar discectomy, we identified 36,479 lumbar discectomy patients. 2,937 (8.1%) of these patients had a prior diagnosis of RA. After matching 4:1 by patient age, sex, and Elixhauser Comorbidity Index (ECI, a longitudinal measure of patient comorbidity burden generated via ICD-9 and 10 diagnosis codes), 8,485 lumbar discectomy patients without RA and 2,149 with RA were included. OUTCOME MEASURES Incidence of severe and minor adverse events in the 90-days following lumbar discectomy, predictive factors for adverse events within 90-days of lumbar discectomy, risk of adverse events within 90-days of lumbar discectomy stratified by patient medication regimen, 5-year survival to reoperation following lumbar discectomy. METHODS Patients undergoing lumbar discectomy were identified from the PearlDiver MSpine dataset. The subset of those with versus without RA were identified and matched 1:4 based on patient age, sex, and ECI scores. The incidence of 90-day adverse events in the two groups was determined and compared by univariate and multivariate analyses. Subgroup analysis was performed based on RA medications being taken. RESULTS Matched lumbar discectomy patients with RA (n=2,149) and without RA (n=8,485) were identified. Controlling for patient age, sex, and ECI, those with RA were at significantly higher odds of any (odds ratio [OR] 3.30), severe (OR 2.78), and minor (OR 3.30) adverse events (p<.0001 for all). Stratifying by medications being taken (and relative to those without RA), there was increasing odds of all adverse events (AAE) based on potency of medications (no biologic or disease modifying antirheumatic drugs [DMARDs] OR 2.33, DMARDs only OR 3.86, biologic±DMARDs OR 5.69 (p<.0001 for all). Despite this, no statistically significant difference in 5-year survival from subsequent lumbar surgery was found between those with versus without RA (p=.1000). CONCLUSIONS Lumbar discectomy patients with RA were found to be at significantly higher risk for 90-day adverse events following lumbar discectomy, and this was incrementally greater for those on increasingly suppressive medications. Lumbar discectomy patients with RA bear specific consideration and perioperative monitoring when considered for lumbar discectomy.
