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
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
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
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 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.

Abstract
STUDY DESIGN A descriptive epidemiologic study. OBJECTIVE To analyze trends and patient characteristics for lumbosacral transforaminal and interlaminar/caudal epidural injection utilization over time. BACKGROUND Lumbosacral transforaminal and interlaminar/caudal epidural injections are considered for varying lumbar pathologies. Reported studies, physician practices, insurance authorization, and other factors may influence utilization patterns over time. METHODS Patients undergoing lumbosacral transforaminal and interlaminar/caudal epidural injections between 2010 and 2019 were identified in the M91Ortho PearlDiver database based on Current Procedural Terminology coding. Patient age, sex, Elixhauser Comorbidity Index (ECI), insurance plan (commercial, Medicaid, Medicare), and region of the country where the procedure was performed (Midwest, Northeast, South, West) were assessed and tracked over the years studied based on prevalence per 100,000 covered lives. RESULTS Lumbosacral transforaminal and interlaminar/caudal epidural injections were identified for 426,039 and 501,228 patients, respectively. The number of injections performed per year decreased over the years studied: for transforaminal injections from 160.81 to 76.36 per 100,000 patients and for interlaminar/caudal injections from 200.53 to 77.56 per 100,000 patients. The decrease in overall injections was greatest for those with Commercial and Medicare coverage (53.40% and 66.50%, respectively), with a smaller drop amongst those with Medicaid coverage (32.39%).Over the years, the average patient undergoing injection was older and there was a relative shift toward transforaminal injections ( P <0.05 for both). In terms of specialty of those performing the injections, they were mostly performed by Anesthesiology specialists (who performed less transforaminal than interlaminar/caudal injections). CONCLUSION Lumbosacral transforaminal and interlaminar/caudal spinal epidural injections were shown to decrease by 52.37% per 100,000 patients from 2010 to 2019. Changing demographics of those undergoing such injections and practice patterns are important to consider in the picture of overall spine service utilization. Variations in injection utilization trends by patient insurance raise questions regarding disparities in care.

Abstract
OBJECTIVE Venous thromboembolism (VTE) is an uncommon, but potentially morbid, complication following foot and ankle fractures. Current standard is to not administer thromboprophylaxis to patients with such injuries. Nonetheless, patient and fracture factors might affect this risk/benefit consideration. The goal of this study was to determine what patients are most at risk. METHODS The M53Ortho Pearldiver database was used to identify patients with fractures isolated to the foot and ankle that were treated non-operatively or operatively. Patients with pilon, other appendicular fractures remote from the foot and ankle, and other traumatic injuries were excluded. The 90-day occurrence of VTE was identified based on codes for deep vein thrombosis or pulmonary embolism. Characteristics of those patients who did and did not have VTEs were compared using chi-square analyses. Multivariate logistical regression was then performed to determined factors independently associated with VTE. Finally, timing of VTE relative to fracture was analyzed. RESULTS A total of 298,886 patients with isolated foot or ankle fractures were identified, of which 1,661 (0.56%) had VTE in the 90 days following fracture. In terms of timing, 27.3% occurred in the first week, and 49.8% occurred in the first three weeks. Independent risk factors for VTE included (in decreasing order):prior VTE (odd ratio [OR] = 25.44), factor V Leiden (OR = 24.34), active cancer (OR = 1.84), specific fracture relative to metatarsal fracture (multiple fractures [OR: 1.51], ankle fracture [OR = 1.51], and calcaneus fracture [OR = 1.24]), surgical treatment (OR = 1.41), male sex (OR = 1.19), greater Elixhauser index (OR = 1.05), and increasing age (OR:1.05 per decade) (p<0.05 for each). CONCLUSIONS The present study found that, although only 0.56% of isolated foot and ankle fractures had a VTE within ninety days. Defined risk factors, such as Factor V Leiden, prior VTE, surgical treatment, active cancer, specific fracture patterns, and surgical treatment significantly affected the odds of their occurrence.

Abstract
Category: Arthroscopy; Ankle Introduction/Purpose: Emergency department (ED) visits following total ankle arthroplasty (TAA) may impact patient satisfaction and healthcare cost. Elucidating the timing of and risk factors for ED visits in this patient population might help facilitate targeted risk reduction strategies. Methods: This retrospective cohort study utilized data from the 2010 to 2019 M91Ortho PearlDiver administrative dataset to identify patients who underwent TAA with at least 90 days of follow-up. 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 insurance plan (commercial, Medicaid, Medicare). The incidence, timing, frequency, and primary diagnoses for 90-day postoperative ED visits were identified and interpreted in the context of one-year postoperative ED visit baseline data. Univariate and multivariate logistic regression analyses were used to determine risk factors for such ED visits. Results: Of 7,600 TAA patients identified, 743 (9.8%) visited the ED within 90 days of their procedure. Of those who visited the ED, one ED visit was reported for 571 patients, two for 117 patients, three for 26 patients, and four or more visits for 29 patients. 37.2% of all ED visits occurred within two weeks following surgery; weekly visits returned to within 0.5% of the population baseline by three weeks after surgery. 90-day readmissions were identified for 289 patients (3.80%) of the cohort. Multivariate analysis revealed several predictors of ED utilization following TAA: younger age (odds ratio (OR) 1.40 per decade decrease), female sex (OR 1.18), higher ECI (OR 1.36 per 2-point increase), and Medicaid coverage (OR 2.74; 1.92-3.90 relative to Medicare) (p < 0.05 each). Regarding reasons for ED visits, surgical site issues were identified for 74.4%, with the most common reason being surgical site pain (60.4%). Conclusion: Of 7,600 TAA patients, 9.8% returned to the ED within 90 days of surgery, with predisposing demographic actors identified. The highest incidence for these ED visits was in the first two postoperative weeks, with surgical site pain being the most common reason. By identifying the timing, predisposing factors, and reasons for ED visits following TAA, targeted care pathways should be able to be adjusted to minimize their occurrence, improve patient experience, and minimize health care utilization/costs.

Abstract
Category: Ankle; Arthroscopy; Other Introduction/Purpose: Physical therapy (PT) following total ankle arthroplasty (TAA) is often considered, but guidelines for its use are not standardized. While there may be patient factors that dictate recommendations, establishing a baseline of utilization practices may set the stage for establishing generalizable recommendations. Methods: This retrospective cohort study employed data from the 2010 to 2019 M91Ortho PearlDiver administrative dataset. Those undergoing TAA were identified based on coding, and patient factors were extracted, including: age, sex, Elixhauser Comorbidity Index (ECI), region of the country in which patients' surgery was performed (midwest, northeast, south, west), and insurance plan (commercial, Medicaid, Medicare). The incidence, timing, and frequency of PT utilization in the 90-days following TAA were identified as occurring at home or in an outpatient setting. Univariate and multivariate logistic regression analyses allowed the identification of predictive factors for PT utilization. Results: Of 6,563 TAA patients identified, 2788 (42.5%) utilized postoperative PT services. Most services were done as an outpatient (63.4%), compared to at home (6.1%). Weekly utilization of PT was greatest in the first week following surgery (17.7% of those who utilized PT) and thereafter followed a roughly bell-shaped curve of utilization with the greatest incidence at seven weeks following surgery (14.9% of those who utilized PT). Multivariate analysis identified multiple predictors of PT utilization following TAA, including: older age (odds ratio [OR] 1.23 per decade increase, p < 0.0001), higher ECI (OR 1.03 per 2-point increase, p = 0.0383), having surgery performed in the midwest, northeast, or western US (relative to the South OR 1.43, p < 0.0001; 1.20, p = 0.0109; and 1.32, p < 0.0001, respectively), and having commercial or Medicaid insurance coverage (relative to Medicare OR 1.96, p < 0.0001 and 1.62, p = 0.0006, respectively). Conclusion: Of 6,563 TAA patients, 42.5% utilized PT within 90 days of surgery. PT utilization was highest in the first- and seventh weeks following surgery, and demographic predictors of PT use were defined. Through identification of timing and predictors of PT utilization following TAA, algorithms for PT usage may be better defined and consistently employed.

Abstract
Background Physical therapy (PT) following total ankle replacement (TAR) is often considered, but guidelines for its use are not standardized. Although patient factors may dictate recommendations, this retrospective cohort study aims to characterize baseline utilization practices to set the stage for establishing generalizable recommendations. Methods TAR patients were identified from the 2010-2019 M91 Ortho PearlDiver data set based on administrative coding. Patient factors were extracted, including age, sex, Elixhauser Comorbidity Index (ECI), region of the country in which patients' surgery was performed (Midwest, Northeast, South, West), and insurance plan (commercial, Medicaid, Medicare). The incidence, timing, and frequency of home or outpatient PT utilization in the 90 days following TAR were identified. Inpatient PT was not captured. Univariate and multivariate logistic regression analyses allowed identification of predictive factors for PT utilization. Results Of 5412 TAR patients identified, postoperative PT services were used by 2453 (45.3%). Most PT was outpatient (38.3% of the study population) compared to home (4.1% of the study population). Weekly utilization of PT was greatest in the first week following surgery (17.7% of PT visits) and thereafter followed a roughly bell-shaped curve, with utilization greatest at 7 weeks following surgery (14.9% of PT visits).Independent predictors of PT utilization following TAR included having surgery performed in the Midwest (relative to the South, OR 1.37, P < .0001), Northeast (OR 1.20, P = .0217), or West (OR 1.26, P < .0021) and having commercial (relative to Medicare, OR 1.87, P < .0001) or Medicaid insurance (OR 1.46, P = .0239). Conclusion Of 5412 TAR patients, 42.5% used PT within 90 days of surgery. PT utilization was highest in the first and seventh weeks following surgery, and demographic predictors of PT use were defined. Through identification of timing and predictors of PT utilization following TAR, PT care pathways may be better defined. Level of Evidence Level III, retrospective cohort study.

Abstract
Background Total ankle replacement (TAR) utilization in the United States has steeply increased in recent decades. Emergency department (ED) visits following TAR impacts patient satisfaction and health care costs and warrant exploration. Methods This retrospective cohort study utilized the 2010 to 2019 M91Ortho PearlDiver data set to identify TAR patients with at least 90 days of follow-up. PearlDiver contains billing claims data across all sites of care throughout the United States for all indications for care. Patient factors extracted included age, sex, Elixhauser Comorbidity Index (ECI), region of the country in which surgery was performed, insurance plan, and postoperative hospital length of stay. Ninety-day postoperative ED visit incidence, timing, frequency, and primary diagnoses were identified and compared to 1-year postoperative ED visit baseline data. Univariate and multivariate logistic regression analyses were used to determine risk factors for ED visits. Results Of 5930 TAR patients identified, ED visits within 90 days were noted for 497 (8.4%) patients. Of all ED visits, 32.0% occurred within 2 weeks following surgery. Multivariate analysis revealed several predictors of ED utilization: younger age (odds ratio [OR] 1.35 per decade decrease), female sex (OR 1.20), higher ECI (OR 1.32 per 2-point increase), TAR performed in the western US (OR 1.34), and Medicaid coverage (OR 2.70; 1.71-4.22 relative to Medicare) (P < .05 each). Surgical site issues comprised 78.0% of ED visits, with surgical site pain (57.0%) as the most common problem. Conclusion Of 5930 TAR patients, 8.4% returned to the ED within 90 days of surgery, with predisposing demographic factors identified. The highest incidence of ED visits was in the first 2 postoperative weeks, and surgical site pain was the most common reason. Pain management pathways following TAR should be able to be adjusted to minimize the occurrence of postoperative ED visits, thereby improving patient experiences and decreasing health care utilization/costs. Level of Evidence Level III, retrospective cohort study.

Abstract
PURPOSE Outcomes after spinal deformity surgery in patients with Marfan syndrome (MFS) are poorly characterized given the rarity of the condition. Updated analyses from nationally representative samples, and comparison to outcomes after more commonly performed procedures for conditions such as adolescent idiopathic scoliosis (AIS) could help define the relative risks. METHODS Using the 2010-2020 PearlDiver administrative databases, patients who underwent posterior spinal fusion for > 7 segments were extracted. MFS patients were matched 1:4 to AIS patients based on age, sex, and Elixhauer comorbidity index (ECI). Ninety-day outcomes and 5-year reoperation rates were compared. Significance was set at p < 0.05. RESULTS In total, 206 MFS patients were matched to 825 AIS patients. After adjusting for age, sex, and ECI, multivariate odds ratios (OR) for 90-day any, serious, and minor adverse events, as well as readmissions, were not significantly different for those with MFS compared to those with AIS (p > 0.05 for each). Five-year reoperation rates were also not significantly different (13.1% for the MFS cohort and 13.0% for the AIS cohort (no difference by log-rank, p = 0.9). CONCLUSION While deformity surgery is much less commonly performed for MFS than AIS, it is not uncommonly considered for patients with this condition. Despite some known technical challenges for MFS deformity surgery, the current study leveraged a large, national database to find that 90-day adverse events and 5-year reoperations were not different for matched MFS and AIS patients undergoing deformity surgery. For select patients, these findings should be useful for surgical planning and patient counseling.

Abstract
BACKGROUND Clinical trials are key to the advancement of products and procedures related to conditions of the shoulder and elbow. Unfortunately, many trials are terminated prior to completion. CLINICALTRIALS gov is a registry and results database maintained by the National Library of Medicine that catalogs trial characteristics and tracks overall recruitment status (eg, ongoing, completed, terminated) for each study as well as reasons for termination. Reasons for trial termination have not been specifically evaluated for shoulder- and elbow-related clinical trials. The current study set out to quantify completed and terminated shoulder- and elbow-related clinical trials, assess reasons for termination, and determine independent predictors of termination by comparing characteristics of completed and terminated trials. METHODS The ClinicalTrials.gov database was queried on August 6, 2021, for all completed and terminated interventional studies registered to date using all available shoulder- and elbow-related search terms. Trial characteristics and reason for termination were abstracted. Univariate and multivariate analyses were performed using trial characteristics to determine independent predictors for trial termination. RESULTS For shoulder-related trials, a total of 662 completed or terminated trials were identified and characterized, of which 51 (8%) were noted to have been terminated. For elbow-related trials, a total of 126 completed or terminated were identified and characterized, of which 16 (13%) were terminated. Difficulties with participant recruitment and/or retention was the individual reason most frequently reported for trial termination, accounting for 51% of terminated shoulder-related trials and 38% of terminated elbow-related trials. For shoulder-related trials, multivariate analysis of primary trial characteristics demonstrated increased odds of trial termination for industry-sponsorship (odds ratio [OR] = 4.2, P = .001) relative to sponsorship from local groups, and blinded studies (OR = 45.8, P = .0003) relative to studies that did not implement any form of blinding. For elbow-related trials, logistic regression did not reveal any of the primary trial characteristics evaluated to be correlated with odds of termination. CONCLUSION Shoulder- and elbow-related clinical trials were terminated at a rate of 8% and 13%, respectively. Difficulties in the recruitment and/or retention of participants were the reason most frequently reported for trial termination. For shoulder-related trials, industry sponsorship and studies with blinding were identified as independent predictors of termination. Given the ethical considerations and the opportunity costs associated with terminated studies, independent predictors and reasons for trial termination should be considered and addressed when possible to increase the rate of clinical trial completion.

Abstract
Background Ehlers Danlos Syndrome (EDS) is a rare connective tissue disorder that results from mutations in collagen genes. Potentially related to laxity and resultant degenerative changes, adult EDS patients may require posterior lumbar fusion (PLF). However, with low numbers, adequately powered outcome studies have been limited. The purpose of this study was to investigate risk of complications, readmissions and reoperations in adult patients with EDS following single-level PLF. Methods A retrospective study using the 2010 to 2020 MSpine Pearldiver dataset was performed. Adult patients undergoing single-level PLF (excluding any with anterior procedures) with and without EDS for which at least 90-day follow up was available were identified. Any cases performed for trauma, tumor, or infection were excluded.Single-level PLF EDS patients were then matched 1:4 with PLF non-EDS patients based on age, sex, and Elixhauser Comorbidity Index (ECI). Rates of ninety-day any, severe, and minor adverse events as well as readmissions were tabulated and compared with chi-square tests. Multivariate logistical regression was then performed (controlling for age, sex, and ECI).Reoperation surgeries over five years were assessed, Kaplan-Meier survival curves generated, and curves of those with and without EDS were compared with log rank test. Results In total, there were 170,100 single-level PLF case identified, of which 242 (0.14%) had EDS. After matching, there were 957 without EDS and 239 with EDS. On multivariate regression, there were no significant differences in 90-day any, severe, or minor adverse events, or readmissions (p>0.05 for each). Over five years, there were also not significant differences in rates of reoperation (p> 0.05). Conclusions For EDS patients undergoing PLF, the current study identified similar 90-day adverse events and 5-year reoperation rates compared to those without EDS. These findings may be useful for patient counseling and surgical planning for those with this rare condition.

Abstract
Background Hidradenitis suppurativa (HS) is a skin disorder characterized by inflammatory skin lesions that are most commonly in the inguinal and axillary regions. These skin lesions are common sites of bacterial growth and are thus a potential risk factor for infection following procedures such as total hip arthroplasty (THA) or total knee arthroplasty (TKA). Material and methods Adult patients undergoing THA or TKA for degenerative etiologies were identified from PearlDiver datasets. For THA and TKA, HS patients were matched 1:4 with non-HS patients based on age, sex, and Elixhauser Comorbidity Index. The incidence of 90-day any, severe, minor, and specific adverse events was compiled and compared with multivariate analyses. Five-year revision rates were plotted on Kaplan-Meier survival curves and compared with log-rank tests. Results For THA, 331,627 patients were identified, of which HS was noted for 481 patients (0.15%). For TKA, 274,161 patients were identified, of which HS was noted for 290 patients (0.11%). Following THA, HS patients had increased odds of wound dehiscence (odds ratio = 2.55, P = .002). Following TKA, HS patients had increased odds of surgical site infection (odds ratio = 1.95, P = .006). All other 90-day adverse events were not significantly different. There was no significant difference in 5-year implant survival in either procedure. Conclusions HS is a rare but identified comorbidity for those undergoing THA or TKA. Although most 90-day adverse events and 5-year implant survival were similar to those without this condition, specific wound-related issues were elevated by roughly twofold. These findings could help inform patients and surgeons.

Abstract
Background Postoperative readmissions are a commonly used metric for quality-of-care initiatives, but emergency department (ED) visits have received far less attention despite their substantial impact on patient satisfaction and healthcare spending. The current study described the incidence and timing of ED visits following single-level ACDF, determined predictive factors and reasons for ED utilization, and compared reimbursement for patients with and without ED use. Methods Single-level ACDF procedures from 2010-2020 were identified in PearlDiver using CPT codes. Patients' age, sex, Elixhauser comorbidity index (ECI) score, region of the country, and insurance coverage were extracted. The incidence, timing, and primary diagnoses for 90-day ED visits and readmissions were determined, as well as total 90-day reimbursement. Variables were compared using univariate analysis and multivariate logistic regression. Results Out of 90,298 patients, 90-day ED visits were identified for 10,701 (11.9%), with the greatest incidence in postoperative weeks 1-2. Readmissions were identified for 3,325 (3.7%) patients. Independent predictors of ED utilization included younger age (OR 1.25 per 10-year decrease, p<0.001), greater ECI score (OR 1.40 per 2-point increase, p<0.001), and insurance type (relative to Medicare, Medicaid [OR 2.15, p<0.001] and commercial plans [OR 1.14, p=0.004]). In postoperative weeks 1-2, 51% of primary ED diagnoses involved the surgical site, while 23% involved the surgical site in weeks 3-13. Compared to patients without ED visits, those who visited the ED had 65% greater mean 90-day reimbursement (p<0.001). Conclusions More than three times as many patients in the current study were found to present to the ED than be readmitted within ninety days of surgery. The identified predictive factors and reasons for ED visits can direct attention to high-risk patients and common postoperative issues. Additional postoperative counseling and integrated care pathways may reduce ED visits, thereby improving patient care and reducing healthcare spending.

Abstract
BACKGROUND CONTEXT Anterior cervical discectomy and fusion (ACDF) is a common surgical procedure. There is markedly less data on outcomes after three- and four-level cases than one- and two-level cases. PURPOSE To compare perioperative 90-day adverse events and 5-year reoperation rates between isolated one-, two-, three-, and four-level ACDF cases. STUDY DESIGN/SETTING Retrospective review of a large national database. PATIENT SAMPLE Overall, 97,081 patients undergoing ACDF were identified, of which one-level cases were 42,382 (43.7%), two-level cases were 24,055 (24.8%), three-level cases were 28,293 (29.1%), and four-level cases were 2,361 (2.4%). OUTCOME MEASURES Ninety-day adverse events and 5-year reoperation rates. METHODS The 2010 to Q1 2020 PearlDiver database was queried to identify patients who underwent elective ACDF for degenerative pathology without corpectomy or concomitant posterior procedures. Univariate and multivariate analyses were performed to compare outcomes of subcohorts with varying number of levels addressed by ACDF. RESULTS Of the 97,081 cases identified, patient characteristics and complication rates differed between the cohorts defined by levels treated. Univariate analyses revealed statistically different rates of 90-day any, serious, and minor adverse event rates between the groups, but the differences were all less than 2.5%. Readmission rates were statistically different by 2.9%, dysphagia by 3.2%, and prolonged length of stay by 6.3%.By multivariate analyses, three-level ACDF cases were not found to have greater 90-day adverse outcomes than two-level cases. Four-level ACDF cases were found to have significantly greater odds ratios of readmission, dysphagia, and prolonged length of stay (relative to one-level cases, OR 1.28, 1.63, and 1.97, respectively) but not other 90-day adverse events. Reoperation rates at five years for one-, two-, three-, and four-level cases were 13.0%, 13.5%, 15.0%, and 22.1%, respectively (log-rank p<.001). CONCLUSIONS The current study represents one of the largest comparative studies of patients undergoing one-, two-, three-, and four-level ACDF. While odds of 90-day adverse events were not greater for three- versus two-level cases, four-level cases had several that were higher odds than one-level cases. Reoperation and dysphagia rates were higher for four-level cases than lesser levels. While these outcomes were found to be acceptable, they should help guide hospital planning and patient counseling.

Abstract
Background: Emergency department (ED) visits after orthopaedic surgery such as anterior
cruciate ligament reconstruction (ACLR) affect patients and health care
systems and should be better understood. Purpose: To determine the incidence, predictors, and reasons for ED visits within 90
days after ACLR. Study Design: Descriptive epidemiologic study. Methods: Patients who had undergone ACLR between 2010 and 2020 were identified in a
national database, and 90-day ED visits, readmissions, risk factors, and
primary diagnoses for visits were determined. One-year postoperative data
were used to establish baseline weekly ED visits for the cohort. Patient
age, sex, Elixhauser comorbidity index, region of the country (Northeast,
Midwest, West, South), and insurance coverage (Medicare, Medicaid, and
commercial) were extracted, and these variables were compared using
univariate analysis and multivariate logistic regression. Results: Out of 81,179 patients, ED visits were identified for 6764 (8.3%), and
readmissions were identified for 592 (0.7%). Overall, 5300 patients had 1 ED
visit, 1020 patients had 2 visits, 275 patients had 3 visits, and 169
patients had ≥4 or more visits; visits occurred within 2 weeks of surgery
38% of the time. Notably, weekly visits returned to baseline at week 3.
Independent predictors of ED utilization from multivariate analysis were
insurance type (relative to commercial insurance: Medicaid [odds ratio [OR],
2.41; 95% CI, 2.23-2.60] and Medicare [OR, 1.38; 95% CI, 1.19-1.60]), higher
Elixhauser comorbidity index (per 2-point increase: OR, 2.24; 95% CI,
2.18-2.29), younger age (per 10-year decrease: OR, 1.23; 95% CI, 1.21-1.24),
female sex (OR, 1.05; 95% CI, 1.02-1.08), and region of the country
(relative to the West: Midwest [OR, 1.33; 95% CI, 1.26-1.39], Northeast [OR,
1.24; 95% CI, 1.18-1.30], and South [OR, 1.17; 95% CI, 1.12-1.23]). In the
first 2 weeks, 67.5% of ED visits were for issues involving the surgical
site, most commonly surgical-site pain (29% of all visits). In the total
90-day period, 39.4% of visits involved the surgical site. Conclusion: Within 90 days of ACLR, >8% of patients visited the ED, while 0.7% were
readmitted. ED visits increased in the first 2 postoperative weeks and
returned to baseline rates around week 3. Within the first 2 weeks,
two-thirds of visits involved the surgical site. Younger patients, patients
with greater comorbidity burden, those in certain regions of the country,
and those with Medicaid had greater odds of ED utilization.
