Patient Self-Reported Allergies and Their Correlation with Thoracic Outlet Syndrome Outcomes.

OBJECTIVES: Thoracic outlet syndrome (TOS) is an uncommon neurovascular disorder that presents as neck and upper extremity pain secondary to brachial plexus trunk or subclavian vasculature compression. The orthopedic literature has correlated patient-reported allergies to postoperative patient-reported outcome (PRO) scores for a variety of surgical procedures. We sought to evaluate patient-reported allergies and PROs following surgical decompression for TOS. METHODS: A chart review was conducted after identifying patients who underwent surgical thoracic outlet decompression by a single surgeon. Patients were contacted and administered five PRO questionnaires via telephone: the QuickDASH Outcome Measure questionnaire (disabilities of the arm, shoulder, and hand [DASH]), the Cervical Brachial Symptom Questionnaire, the Single Assessment Numeric Evaluation, the 12-Item Short Form Survey, and the Numeric Rating Scale (a visual analogue scale). A bivariate analysis of Pearson's correlation coefficient (r) was used to determine the associations of allergies with questionnaires and demographic variables. RESULTS: Of the 393 patients (128 males and 265 females) identified in the study, 75 (24%) responded and completed all of the questionnaires, 18 (24%) males and 57 (76%) females. A significant correlation was found between the number of allergies reported and the QuickDASH Outcome Measure questionnaire (r = 0.375, P < 0.001), the Cervical Brachial Symptom Questionnaire (r = 0.295, P = 0.01), change in the Single Assessment Numeric Evaluation score (r = -0.310, P < 0.01), change in the visual analogue scale (r = 0.244, P = 0.035), sex (r = 0.245, P = 0.034), and the number of medications (r = 0.642, P < 0.001). CONCLUSIONS: The increased frequency of patient-reported allergies is significantly associated with worse PRO scores for women undergoing TOS surgical decompression. Better understanding this association can help physicians counsel patients on expected outcomes.

Eccentric Hamstring Strength Imbalance among Football and Soccer Athletes.

OBJECTIVES: Hamstring strain injuries (HSI) are common among football and soccer athletes. Eccentric strength imbalance is considered a contributing factor for HSI. There is, however, a paucity of data on hamstring imbalances of soccer and American football athletes as they age and advance in skill level. High school athletes will display greater interlimb discrepancies compared with collegiate and professional athletes. In addition, soccer athletes will exhibit greater hamstring asymmetry than American football athletes. METHODS: Hamstring testing was performed on soccer and American football athletes using the NordBord Hamstring Testing System (Vald Performance, Albion, Australia). Age, sex, weight, sport specialization, and sport level were recorded. Maximum hamstring forces (N), torque (N · m), and work (N · s) were measured. Hamstring imbalance (%) was calculated by dividing the absolute value of the difference in leg forces divided by their sum. One-way analysis of variance and independent sample t tests compared measurements between athlete groups. RESULTS: A total of 631 athletes completed measurements, including 88 high school male soccer, 25 college male soccer, 23 professional male soccer, 83 high school female soccer, 28 college female soccer, 288 high school football, and 96 college football athletes. High school soccer players displayed significantly greater imbalances for torque (P = 0.03) and work (P < 0.01) than football athletes. Imbalances for maximum force (P = 0.035), torque (P = 0.018), and work (P = 0.033) were significantly higher for male soccer athletes in high school compared with college- and professional-level athletes. Female high school soccer players had significantly higher imbalance in torque (P = 0.045) and work (P = 0.001) compared with female collegiate soccer players. Football athletes did not experience significant changes in force imbalances between skill levels. CONCLUSIONS: High school soccer athletes exhibit greater hamstring imbalances than football athletes. Higher levels of play in soccer, for both male and female athletes, correlate with less hamstring asymmetry.

Gender Disparities Among Professional Team Sports Medicine Physicians.

OBJECTIVE: Although recent trends from the Accreditation Council for Graduate Medical Education (ACGME) present encouraging growth of female representation in sports medicine, the field is still lagging behind other specialties. This study investigates gender disparities among physicians providing care for professional sports teams in male and female sports leagues. DESIGN: Information regarding physicians providing sports medicine care to professional teams obtained by database queries (May 2021). Chi-square analysis compared gender data of orthopaedic team physicians with American Orthopaedic Society for Sports Medicine (AOSSM) and American Academy of Orthopaedic Surgeons (AAOS) membership, residency, and fellowship census data. Primary care sports medicine physicians were compared with American Medical Society for Sports Medicine (AMSSM) and primary-care sports medicine fellowship census data. SETTING: Professional sports health care. STUDY POPULATION: Professional league physicians. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Gender, residency, and fellowship training of professional league physicians. RESULTS: Among a total of 608 team physicians, 572 (93.5%) were male and 40 (6.5%) were female. Orthopedic surgeons comprised 64.7% of the physicians. Fourteen (3.6%) team orthopedic surgeons were female. Thirty-five percent of team physicians were primary care sports medicine physicians. Twenty-six primary care sports medicine physicians (11.6%) were female. Orthopaedic female team physician representation overall was comparable with AOSSM and AAOS membership but significantly less than orthopaedic surgery residents and sports medicine fellows ( P < 0.01). Women's National Basketball Association orthopaedic team physicians were more represented than female membership among AOSSM, AAOS, and orthopaedic sports medicine fellows ( P < 0.01). Except for the WNBA, Premiere Hockey Federation, National Women's Soccer League, and United States Football League, female primary care sports medicine physicians were underrepresented in professional sports compared with AMSSM membership and primary care sports fellows ( P < 0.01). CONCLUSION: Overall, female representation is poor among orthopaedic surgeons and primary care physicians providing sports medicine care to professional teams. Leagues encompassing female athletes tend to have better representation of female physicians. LEVEL OF EVIDENCE: IV.

Elective Hand Surgery Is Delayed among Private Insurance Holders.

OBJECTIVES: Patients with private healthcare plans often defer nonemergent or elective procedures toward the end of the year once they have met their deductible. No previous studies have evaluated how insurance status and hospital setting may affect surgical timing for upper extremity procedures. Our study aimed to evaluate the influence of insurance and hospital setting on end-of-the-year surgical cases for elective carpometacarpal (CMC) arthroplasty, carpal tunnel, cubital tunnel, and trigger finger release, and nonelective distal radius fixation. METHODS: Insurance provider and surgical dates were gathered from two institutions' electronic medical records (one university, one physician-owned hospital) for those undergoing CMC arthroplasty, carpal tunnel release, cubital tunnel release, trigger finger release, and distal radius fixation from January 2010 to December 2019. Dates were converted into corresponding fiscal quarters (Q1-Q4). Using the Poisson exact test, comparisons were made between the case volume rate of Q1-Q3 and Q4 for private insurance and then for public insurance. RESULTS: Overall, case counts were greater in Q4 than the rest of the year at both institutions. There was a significantly greater proportion of privately insured patients undergoing hand and upper extremity surgery at the physician-owned hospital than the university center (physician owned: 69.7%, university: 50.3%; P < 0.001). Privately insured patients underwent CMC arthroplasty and carpal tunnel release at a significantly greater rate in Q4 compared with Q1-Q3 for both institutions. Publicly insured patients did not experience an increase in carpal tunnel releases during the same period at both institutions. CONCLUSIONS: Privately insured patients underwent elective CMC arthroplasty and carpal tunnel release procedures in Q4 at a significantly greater rate than publicly insured patients. This finding suggests private insurance status, and potentially deductibles, influence surgical decision making and timing. Further work is needed to evaluate the impact of deductibles on surgical planning and the financial and medical impact of delaying elective surgeries.

Bioactive Knee Sleeve for Osteoarthritis: A Small Cohort Study.

OBJECTIVES: Osteoarthritis (OA) is one of the most prevalent musculoskeletal ailments worldwide. Numerous conservative therapies exist, but evidence for such treatments remains conflicting. Recently, there has been growing interest surrounding bioactive sleeves for managing knee arthritis; however, the literature on their efficacy for relieving pain and improving function in the setting of knee OA is limited. As such, we sought to investigate the effect of a bioactive sleeve on patient-reported outcome measures in a small cohort of patients with OA. METHODS: Patients with knee OA were given a bioactive sleeve (Reparel, Chico, CA) and asked to refrain from lifestyle modifications and intraarticular corticosteroid injections. Lysholm Knee Score, Oxford Knee Score, Knee Injury and OA Outcome Score (KOOS), Single Assessment Numeric Evaluation, and Visual Analog Scale score were obtained at baseline, 2 weeks, 6 weeks, and 3 months. OA severity was evaluated using the Kellgren and Lawrence (KL) classification system. The Wilcoxon signed rank test was used to compare baseline patient-reported outcomes with 2-week, 6-week, and 3-month time points. Bivariate correlation was used to evaluate the relation between patient-reported outcome measures and KL classification. RESULTS: The cohort was composed of 14 participants-4 males and 10 females-with a mean age of 62.2 ± 13.2 years and a body mass index of 33.7 ± 5.8. The average KL grade was 2.9 (range 2-4). KOOS pain, symptoms, activities of daily living, and quality of life increased significantly at 2 weeks, 6 weeks, and 3 months. KOOS sport and recreation significantly increased at 3 months. The Oxford Knee Score was significantly greater at 2 weeks, 6 weeks, and 3 months. The Lysholm Knee Score was significantly greater at 6 weeks and 3 months. The Single Assessment Numeric Evaluation attained significant improvement at 3 months, and the Visual Analog Scale improvement was significant at 2 weeks. No statistically significant difference was attained with University of California at Los Angeles activity score. Outcome scores did not correlate with KL classification. CONCLUSIONS: These data suggest that a bioactive sleeve may improve patient-reported pain, symptoms, and function in the setting of knee OA. Further research is needed to better understand the role of bioactive sleeves for patients with knee arthritis.

COVID-19 Impact on Orthopedic Surgeons: Elective Procedures, Telehealth, and Income.

OBJECTIVES: The purpose of this study was to investigate the response in orthopedic surgery to the coronavirus disease 2019 (COVID-19) pandemic across the United States by surveying surgeons about their care setting, timing of restrictions on elective surgery, use of telehealth, and estimated economic impact. METHODS: A survey was distributed via REDCap through state orthopedic organizations between April and July 2020. The 22-question digital survey collected information regarding restrictions on elective procedures, location of care, utilization of telehealth, and estimated reductions in annual income. RESULTS: In this study, 192 participants responded to the survey (average age 49.9 ± 11.0 years, 92.7% male). Responses primarily originated from Alabama (30.2%), Georgia (30.2%), and Missouri (16.1%). The remainder of the responses were grouped into the category "other." Respondents did not vary significantly by state in operative setting or income type (salary, work relative value units, or collections). Most of the participants documented elective procedure restrictions in hospital and ambulatory settings. The highest frequency of closures occurred between March 18 and 20 (47% in hospital, 51% in ambulatory). Of the participants, financial loss estimates varied across states (P = 0.005), with 50% of physicians claiming >50% losses of income in Alabama (24% Georgia, 10% Missouri, 31% other). Regarding telehealth, practices set up for these services before 2020 varied across states. None of the orthopedic practices in Alabama had telehealth before the COVID-19 pandemic (Missouri 25%, Georgia 9%, other 8%, P = 0.06); however, respondents generally were split when considering the anticipation of implementing telehealth into routine practice. CONCLUSIONS: Most practices did implement restrictions for elective clinic visits and procedures early during the pandemic. COVID-19 ultimately will result in a large revenue loss for elective orthopedic practices. Services such as telehealth may help offset these losses and help deliver orthopedic care to patients remotely.

Is outpatient shoulder arthroplasty safe? A systematic review and meta-analysis.

BACKGROUND: Amid rising health care costs and recent advances in surgical and anesthetic protocols, the rate of outpatient joint arthroplasty has risen steadily in recent years. Although the safety of outpatient total knee arthroplasty and total hip arthroplasty has been well established, outpatient shoulder arthroplasty is still in its infancy. The purpose of this study was to synthesize the current literature and provide further data regarding the outcomes and safety of outpatient shoulder arthroplasty. METHODS: A systematic review was conducted following the standard PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Included were studies that evaluated the outcomes of patients undergoing outpatient total shoulder arthroplasty (TSA) or reverse TSA. Meta-analysis was conducted using Mantel-Haenszel statistics to generate odds ratios (ORs) and their corresponding 95% confidence intervals (CIs) comparing outpatient and inpatient shoulder arthroplasty. RESULTS: Twelve studies were included, with a total of 194,513 patients, of whom 7162 were outpatients. Of the studies, 8 were level III and 4 were level IV. The average age of the outpatients was 66.6 years, and the average age of the inpatients was 70.1 years. The overall OR for complications was significantly lower in outpatients (OR, 0.40; 95% CI, 0.35-0.45) than in inpatients. There was no significant difference in rates of 90-day readmission (OR, 0.88; 95% CI, 0.75-1.03), revision (OR, 0.96; 95% CI, 0.65-1.41), and infection (OR, 0.93; 95% CI, 0.64-1.35) when comparing outpatients with inpatients. CONCLUSION: Outpatient TSA, in an appropriately selected patient population, is safe and results in comparable patient outcomes to those of inpatient shoulder arthroplasty. Given the expected increase in the number of patients requiring TSA, surgeons, hospital administrators, and insurance carriers should strongly consider the merits of a cost- and care-efficient approach to total shoulder replacement.

Quality Improvement Tools in Total Joint Arthroplasty: A Systematic Review.

Systems review and quality improvement (QI) is a significant need within orthopaedic surgery. The focus of this paper is to systematically review QI principles utilized in total joint arthroplasty to determine most successful QI tools. A systematic search on MEDLINE/Pubmed, Embase, Cochrane Library and other sources was conducted from September 1991 through October 2018. The three primary improved outcomes from each article were recorded along with the date, author and subspecialty. Thirty-four eligible studies related to joint arthroplasty were identified for inclusion in the systematic review. The most common outcomes that were improved in these publications were: length of stay (LOS), cost, medication management, and patient education. Lean, clinical care pathways (CCP), plan-do-check-act (PDCA), and shared decision-making improved those metrics. Four metrics were found that were consistently improved by certain quality improvement tools: LOS, cost, medication management, and patient education. Further research is warranted to continue to build a framework for quality improvement in orthopaedic surgery. (Journal of Surgical Orthopaedic Advances 30(3):125-130, 2021).

Corticosteroid Injections May Increase Retear and Revision Rates of Rotator Cuff Repair: A Systematic Review.

PURPOSE: To synthesize the clinical outcome data of preoperative and postoperative corticosteroid injections (CIs) and their effect on rotator cuff repairs (RCRs). METHODS: A systematic review was performed to identify studies that reported the results or clinical outcomes of RCRs in patients receiving either preoperative or postoperative CIs. The searches were performed using MEDLINE, Google Scholar, and Embase, and studies were chosen following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. RESULTS: A total of 11 studies were included with data for 176,352 shoulders: 6 studies involving 175,256 shoulders with data regarding preoperative CIs, 4 studies involving 1,096 shoulders with data regarding postoperative CIs, and 1 study with 212 shoulders containing preoperative and postoperative data. Preoperative CIs were found in 3 studies to increase the risk of revision surgery when administered within 6 months (odds ratio [OR], 1.38-1.82) and up to 1 year (OR, 1.12-1.52) prior to RCR, with revision rates in 2 studies being highest when patients received 2 or more injections (OR, 2.12-3.26) in the prior year. Postoperative CIs reduced pain and improved functional outcomes in 5 studies without increasing the retear rates (5.7%-19% for CI and 14%-18.4% for control) in most studies. CONCLUSIONS: CIs provide benefit by relieving pain and improving functional outcome scores. However, repeated preoperative CIs may increase retear rates and the likelihood of revision surgery. A lower frequency of CI and longer preoperative waiting period after CI should be considered to decrease such risks. Postoperative CIs several weeks after RCR do not appear to increase retear rates. LEVEL OF EVIDENCE: Level IV, systematic review of Level I through IV studies.

Patient Perception of Orthopedic Surgeon Reimbursement.

Significant attention has been directed at evaluating reimbursement rates to orthopedic surgeons for various surgical procedures. To evaluate patients' understanding of the surgeon reimbursement process, studies using patient surveys have been conducted to determine patients' perceptions of orthopedic surgeon compensation. To date, there has been no systematic review to consolidate the data of these studies. This study aimed to synthesize the findings of these individual studies across multiple subspecialties of orthopedic surgery to evaluate the potential discrepancy between how much patients believe orthopedic surgeons are reimbursed and the actual reimbursement rate. We performed a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to identify studies that report findings of patient perceptions of orthopedic surgeon reimbursement for various procedures. Searches were conducted using MEDLINE through PubMed, Embase, and Scopus. Summary estimates of reimbursement discrepancies across subspecialties and overall were reported as unweighted averages of the individual study results within each group. Twelve studies were identified that met inclusion criteria, constituting 4309 surveys. These survey studies measured patients' perceptions of how much orthopedic surgeons are reimbursed for common procedures, including anterior cruciate ligament reconstruction, arthroscopic meniscectomy, carpal tunnel release, rotator cuff repair, multiple spine procedures and total shoulder, hip, and knee arthroplasty. It was found that patients reported reasonable surgeon's fees to be 11.2 times more than actual Medicare reimbursement. Among individual studies, the largest discrepancies were seen in total hip arthroplasty (26 times), whereas the smallest difference was in anterior cruciate ligament reconstruction (1.6 times). On average, patients estimated Medicare reimbursement rates to be 5.9 times higher than the actual surgeon reimbursement. Patients consistently overestimate how much orthopedic surgeons are reimbursed for common orthopedic procedures. The results of this systematic review suggest that patients may value these procedures more than what Medicare reimburses. Such information may help educate the public, direct policy, and increase transparency between orthopedic surgeons and patients.

Clinical outcomes following conservative and surgical management of floating shoulder injuries: a systematic review.

BACKGROUND: Floating shoulder is an uncommon injury characterized by fractures of the clavicle and ipsilateral scapular neck. No consensus exists on management. The purpose of this study was to analyze the existing literature on treatment and clinical outcomes of floating shoulder injuries to provide a baseline understanding of current treatment strategies of this injury. METHODS: A systematic review was performed to identity published literature on outcomes and management of floating shoulder injuries. Searches were performed using PubMed, Embase, and SCOPUS. RESULTS: Seventeen studies were identified that included data for 371 shoulders. The mean reported age was 39.4 years (range, 16-82) and the mean follow-up was 49.4 months (range, 6-312). The major mechanism of injury was motor vehicle accident (51%) followed by fall from height (16%). Of the 371 shoulders, 215 (58%) were treated surgically, whereas 156 shoulders (42%) were managed nonoperatively. The most commonly reported outcome score was the Constant-Murley score (9 studies), followed by the Herscovici Floating Shoulder Injury score (5 studies). The mean Constant-Murley score was 80% of ideal maximum for both shoulders treated surgically and those treated nonoperatively. CONCLUSION: Satisfactory outcomes can be expected following both surgical fixation and nonoperative management of floating shoulder injuries when appropriately individualized to the patient, as evidenced by clinical outcome scores. Floating shoulder injuries with significant displacement of the scapular neck may benefit from surgical fixation of both the clavicle and scapula fractures. In those with minimal or nondisplaced scapular neck fractures, good outcomes may be achieved when treated nonoperatively or with surgical fixation of the clavicle alone.

Subacromial Spacer Implantation for the Treatment of Massive Irreparable Rotator Cuff Tears: A Systematic Review.

PURPOSE: To synthesize and report the early clinical and radiographic outcomes associated with subacromial spacer use in patients with massive irreparable rotator cuff tears. METHODS: A systematic search on MEDLINE, Embase, and Cochrane Library databases was performed during February 2018. Included studies were evaluated regarding the level of evidence and quality using the methodological index for nonrandomized studies. Patient demographics, intraoperative findings, clinical and radiographic outcomes, and complications were recorded for each of the included studies. RESULTS: Seven eligible studies including 204 shoulders from 200 patients with subacromial spacer implantation were identified (6 Level IV studies and 1 Level III study). The mean methodological index for nonrandomized studies score for noncomparative studies was 11, whereas that of comparative studies was 15. The mean age of patients was 67.6 years, and the mean reported follow-up time was 19.4 months. All patients had Goutallier stage 3 and 4 fatty infiltration on magnetic resonance imaging. All studies reported consistent improvement in the total Constant score or American Shoulder and Elbow Surgeons score over the duration of follow-up. A total of 6 (3%) complications were reported in the included studies. Two studies detailed radiographic outcomes, with discrepant changes in the acromiohumeral interval. CONCLUSIONS: Patients undergoing subacromial spacer implantation for the treatment of massive irreparable rotator cuff tears have satisfactory outcomes at the 2- to 3-year follow-up with a low rate of complications. LEVEL OF EVIDENCE: Level IV, systematic review of 1 Level III and 6 Level IV studies.

Management of Three- and Four-Part Proximal Humerus Fractures.

The management of three- and four-part proximal humerus fractures remains controversial because the literature has supported all forms of management, including nonsurgical management, open reduction and internal fixation (ORIF), and shoulder arthroplasty. Specific patient factors ultimately influence the decision of which treatment best fits the patient and the fracture. Surgeons should understand the rationale for nonsurgical and surgical management of these fractures, including ORIF and reverse shoulder arthroplasty.

Does Medicaid expansion improve access to care for the first-time shoulder dislocator?

BACKGROUND: The purpose of this study was to assess the effect of individual state Medicaid expansion status on access to care for shoulder instability. METHODS: Four pairs of Medicaid expanded (Louisiana, Kentucky, Iowa, and Nevada) and unexpanded (Alabama, Virginia, Wisconsin, and Utah) states in similar geographic locations were chosen for the study. Twelve practices from each state were randomly selected from the American Orthopedic Society for Sports Medicine directory, resulting in a sample size of 96 independent sports medicine offices. Each office was called twice to request an appointment for a fictitious 16-year-old first-time shoulder dislocator with either in-state Medicaid insurance or Blue Cross Blue Shield (BCBS) private insurance. RESULTS: A total of 91 physician offices in 8 states were contacted by telephone. An appointment was obtained at 36 (39.6%) offices when calling with Medicaid and at 74 (81.3%) offices when calling with BCBS (P < .001). Thirty-five (38.5%) offices were able to make appointments for both types of insurance, 39 (42.9%) for only BCBS, 1 (1.1%) for only Medicaid, and 16 (17.5%) for neither. For Medicaid patients, an appointment was booked in 13 (27.7%) clinics from Medicaid expanded states and in 23 (52.3%) clinics from unexpanded states (P = .016). CONCLUSION: For a first-time shoulder dislocator, access to care is more difficult with Medicaid insurance compared with private insurance. Within Medicaid insurance, access to care is more difficult in Medicaid expanded states compared with unexpanded states. Medicaid patients in unexpanded states are twice as likely as those in expanded states to obtain an appointment.

The surgical anatomy of the dorsal scapular nerve: a triple-tendon transfer perspective.

BACKGROUND: Iatrogenic or traumatic injury to the spinal accessory nerve is a rare but debilitating injury. An effective treatment, known as the Eden-Lange modification triple-tendon transfer procedure, involves the transfer of the rhomboid major (RM), rhomboid minor (Rm), and levator scapulae (LS). Careful detachment of their insertions is necessary to avoid injury of the dorsal scapular nerve (DSN). This study evaluated the surgical anatomy and safety of the DSN relative to this procedure. METHODS: The study used 12 cadavers (22 shoulders). The RM, Rm, and LS were detached from their insertions, and the DSN was dissected. Measurements were taken to evaluate the anatomy of each relative to the triple-tendon transfer procedure. Additional measurements were taken to identify "danger zones" for DSN injury, regarding detachment of RM, Rm, and LS from their respective insertions. RESULTS: Measurements of the 22 shoulders included in the study showed wide variation in anatomy. The minimum distance between the scapula and the DSN at the vertebral scapular border was 0.7 cm, suggesting that care and precision are needed to perform this technique. The region where the DSN crosses the superior border of the Rm was shown to be the greatest "danger zone" of this technique, with a mean distance to the scapula of 1.61 ± 0.53 cm CONCLUSIONS: This study provides insight into the surgical anatomy of the DSN relative to a rare but successful procedure used to treat trapezius paralysis. The results of this study can inform the surgeon regarding potential anatomic considerations when performing the triple-tendon transfer.

Return to Driving After Hip Arthroscopy.

OBJECTIVE: The objective of this study was to evaluate patients' braking performance using a modern driving simulator after undergoing a right hip arthroscopy. DESIGN: This prospective study included 5 total driving sessions at which measurements were taken. SETTING: The study was conducted at an academic medical center. PATIENTS: A total of 14 patients scheduled to undergo a right hip arthroscopy were enrolled and compared with a control group of 17 participants to account for a potential learning phenomenon. INTERVENTIONS: Patients drove in the simulator preoperatively to establish a baseline, and then drove again at 2, 4, 6, and 8 weeks postoperatively. The control group did not undergo any type of surgical procedure. The main independent variable was time from surgery. MAIN OUTCOME MEASURES: A modern driving simulator was used to measure initial reaction time (IRT), throttle release time (TRT), foot movement time (FMT), and brake travel time (BTT). The braking reaction time (BRT) was calculated as the sum of IRT + TRT + FMT, and the total braking time (TBT) was calculated as the sum of BRT + BTT. RESULTS: The experimental group showed no significant changes in BTT (P = 0.11, (Equation is included in full-text article.)= 0.04) nor TBT (P = 0.20, (Equation is included in full-text article.)= 0.03) over the duration of 8 weeks. Although the experimental group did exhibit significant improvements in IRT (P = 0.002), TRT (P < 0.0001), FMT (P < 0.0001), and BRT (P = 0.0002) between preoperative and 2 weeks postoperative driving sessions, there were no significant changes thereafter. The mean preoperative TBT and 2 weeks postoperative TBT for the experimental group were 3.07 seconds (SD = 0.50) and 2.97 seconds (SD = 0.57), respectively. No learning phenomenon was observed in the control group. CONCLUSIONS: This study's findings suggest that patients may return to driving 2 weeks postoperatively from a right-sided hip arthroscopy procedure.

Outcomes for subscapularis management techniques in shoulder arthroplasty: a systematic review.

BACKGROUND: This systematic review aims to synthesize published data for the most common subscapularis takedown and repair to compare outcomes in the setting of shoulder arthroplasty. METHODS: Searches of MEDLINE and Cochrane Library databases identified studies that reported clinical or radiologic outcomes for subscapularis management in the setting of shoulder arthroplasty. Comparisons included musculotendinous integrity, subscapularis testing and strength, shoulder range of motion, and functional outcome scores. RESULTS: The 14 included studies reported considerable variability in techniques, outcomes, and musculotendinous integrity. Lesser tuberosity osteotomy (LTO) demonstrated better healing rates (93.1%) than subscapularis peel (SP; 84.1%) and midsubstance tenotomy (ST; 75.7%), although not significantly different. A statistically significant increase in fatty infiltration was found after surgery across techniques, and range of motion and strength were similar. Mean rates of normal results for belly-press and lift-off tests were uniformly better for LTO (79.1% and 80.7%) over ST (66.7% and 65.6%), although multiple studies showed poor correlation between subscapularis functional testing and musculotendinous integrity. Mean total Constant and Western Ontario Osteoarthritis of the Shoulder Index outcome scores were slightly better for LTO (77.6, 84.2) than for SP (71.8 and 82.7). Mean American Shoulder and Elbow Surgeons scores favored the ST group (80.8) over the SP (79.1) and LTO (73) groups. CONCLUSIONS: The data suggest no significant differences exist for postoperative musculotendinous integrity or clinical outcomes among the subscapularis management techniques in shoulder arthroplasty. Subscapularis healing and integrity appear to favor the lesser tuberosity takedown method. Additional randomized controlled comparisons with long-term follow-up are needed to more effectively compare these surgical approaches.

Clinical outcomes of suprascapular nerve decompression: a systematic review.

BACKGROUND: Suprascapular neuropathy is an uncommon clinical diagnosis. Although there have been a number of case series reporting on this pathologic process, to date there has been no systematic review of these studies. This study aimed to synthesize the literature on suprascapular neuropathy with regard to clinical outcomes. The secondary objective was to detail the diagnosis and treatment of suprascapular neuropathy and any associated complications. METHODS: A systematic review was performed to identify studies that reported the results or clinical outcomes of suprascapular nerve decompression. The searches were performed using MEDLINE through PubMed and Cochrane Database of Systematic Reviews. RESULTS: Twenty-one studies comprising 275 patients and 276 shoulders met inclusion criteria. The mean age was 41.9 years, and mean follow-up was 32.5 months. The most common symptom was deep, posterior shoulder pain (97.8%), with a mean duration of symptoms before decompression of 19.0 months; 94% of patients underwent electrodiagnostic testing before decompression, and 85% of patients had results consistent with suprascapular neuropathy. The most common outcome reported was the visual analog scale score, followed by the Constant-Murley score. The mean postoperative Constant-Murley score obtained was 89% of ideal maximum. Ninety-two percent of athletes were able to return to sport. Only 2 (0.74%) complications were reported in the included studies. CONCLUSIONS: Surgical decompression in the setting of suprascapular neuropathy leads to satisfactory outcomes as evidenced by the patient-reported outcomes and return to sport rate. Furthermore, the rate of complications appears to be low.

Nonoperative management versus reverse shoulder arthroplasty for treatment of 3- and 4-part proximal humeral fractures in older adults.

BACKGROUND: The treatment of 3- and 4-part proximal humeral fractures in the older adult is controversial. No study has directly compared reverse shoulder arthroplasty (RSA) with nonoperative treatment for these fractures. The purpose of this study was to compare clinical and patient-reported outcomes between RSA and nonoperative treatment groups. METHODS: A retrospective review was performed on all 3- and 4-part proximal humeral fractures treated with either RSA or nonoperative treatment with minimum 1-year follow-up. All patients in the nonoperative cohort were offered RSA but declined. Objective patient data were obtained from medical records. Patient-reported outcomes including visual analog scale score, Single Assessment Numeric Evaluation score, Penn Shoulder Score, American Shoulder and Elbow Surgeons score, resiliency score, and Veterans Rand-12 scores were obtained at follow-up. Statistical analysis was performed by use of the Student t test for continuous variables and χ2 analysis for nonparametric data. RESULTS: We analyzed 19 nonoperative and 20 RSA patients with a mean follow-up period greater than 2 years (29 months in nonoperative group and 53 months in RSA group). There were no differences in range of motion between groups (forward elevation, 120° vs 119° [P = .87]; external rotation, 23° vs 31° [P = .06]). No differences between the nonoperative and RSA groups were noted for any patient-reported outcomes. Among patients receiving RSA, there was no difference in outcomes in those undergoing surgery less than 30 days after injury versus those receiving delayed RSA. CONCLUSIONS: This study suggests that there are minimal benefits of RSA over nonoperative treatment for 3- and 4-part proximal humeral fractures in older adults.

Arthroscopic decompression at the suprascapular notch: a radiographic and anatomic roadmap.

BACKGROUND: Arthroscopic decompression of the suprascapular nerve (SSN) at the suprascapular notch is a technically demanding procedure. Additional preoperative and intraoperative information may assist surgeons. The purpose of this study was to (1) identify which imaging modality most accurately represents the anatomic distance to the notch and (2) quantify the mean intraoperative distances from routine arthroscopic portals to the notch. METHODS: Ten matched pairs of fresh cadaveric shoulders were imaged by roentgenogram, computed tomography (CT), magnetic resonance imaging, and 3-dimensional (3D) CT, followed by arthroscopic SSN decompression at the notch and anatomic dissection. Measurements obtained included the distances from the anterolateral, posterior, and SSN portal sites to the notch in addition to the distance from the anterolateral acromion to the notch. Statistical analysis with Spearman correlation coefficients and Bland-Altman plots were used to determine the correlation and agreement between measurements. RESULTS: The preoperative imaging modality with the highest correlation to anatomic distances from the anterolateral acromion to the notch was 3D CT (Rs = 0.90, P < .0001). The mean intraoperative distances to the notch from the anterolateral, posterior, and SSN arthroscopic portals were 89 mm, 88 mm, and 49 mm, respectively. The mean anatomic distance from the anterolateral acromion to the notch was 64 mm. CONCLUSIONS: Preoperative imaging with 3D CT may assist surgeons in performing arthroscopic SSN decompression. Understanding of the mean distances from the portal sites to the suprascapular notch and being cautious of arthroscopic instruments placed beyond 9 cm from laterally based portals may result in safer intraoperative medial dissection.
