Abstract
BACKGROUND The influence of position of the humeral tray (inlay or onlay) on clinical outcomes in reverse shoulder arthroplasty (RSA) is a topic of debate. The purpose of this study was to compare clinical and radiographic outcomes of patients with cuff tear arthropathy treated with RSA systems with inlay or onlay humeral tray design, similar neck-shaft angles, and lateralized glenospheres. METHODS This was a retrospective study of prospectively obtained data from one tertiary care center. We identified all patients who underwent primary RSA between 2009 to 2017 (N=511). We included 102 patients with diagnosed cuff tear arthropathy treated with RSA prostheses with a lateralized glenosphere and 135˚ neck-shaft angle (with either an inlay or onlay humeral tray design) who had a minimum of two years of follow-up (mean, 44 months; range, 24-125 months). Sixty-three patients (62%) had an inlay humeral tray (inlay group) and 39 (38%) had an onlay tray (onlay group). All patients underwent preoperative and postoperative evaluations, including measures of patient-reported outcomes (PROs), shoulder range of motion (ROM) testing, and radiographic imaging. Clinical relevance of changes in PROs and ROM was evaluated using published values for minimal clinically important differences. RESULTS The two groups did not differ by demographic characteristics except for a higher proportion of women in the inlay group (75%) than in the onlay group (56%) (P=.04). Preoperative PROs and ROM were not significantly different between groups. At final follow-up, PROs and ROM were not different between groups in terms of statistical significance or clinical relevance. We found no significant differences in the rate of baseplate loosening (inlay, 3.2% vs onlay, 5.1%, P=.63), revision surgery (inlay, 0% vs onlay 5.1%, P=.07), acromial stress fracture (inlay, 3.2% vs onlay, 5.1%, P=.63), prosthesis dislocation (inlay, 0% vs onlay, 2.6%, P=.20), or scapular notching (inlay, 21% vs onlay, 7.7%, P=.08). CONCLUSION At two-year minimum follow-up, the position of the humeral tray in RSA prostheses (either inlay or onlay) for cuff tear arthropathy was not associated with PROs, shoulder ROM, or rates of complications, including baseplate loosening, acromial stress fracture, and scapular notching.

Abstract
BACKGROUND Reverse total shoulder arthroplasty (RTSA) has become an increasingly popular treatment strategy in the management of complex proximal humeral fractures (PHF). However, no definitive consensus has been reached regarding the optimal surgical timing of RTSA following PHF, particularly considering nonoperative management is often a viable option. Therefore, the aim of this study was (1) to identify optimal timing intervals that maximize the likelihood of revision following RTSA and (2) to determine differences in revision etiologies using the identified timing intervals. METHODS A retrospective cohort analysis of patients undergoing PHF-indicated RTSA from 2010 to 2021 was conducted using a national administrative claims database. Stratum specific likelihood ratio (SSLR) analysis was conducted to determine data-driven timing strata between PHF and RTSA that maximized the likelihood of revision surgery within 2-years of RTSA. To control for confounders, multivariable regression analysis was conducted to confirm the identified data-driven strata's association with 2-year revision rates as well as compare the likelihood of various indications for revision including mechanical loosening, dislocation, periprosthetic joint infection (PJI), and periprosthetic fracture (PPF). RESULTS In total, 11,707 patients undergoing TSA following PHF were included in this study. SSLR analysis identified two timing categories: 0-6 weeks and 7-52 weeks from the time of PHF to TSA surgery. Relative to the 0-6 week cohort, the 7-52 week cohort was more likely to undergo revision surgery within 2-years (OR: 1.93, P < 0.001). Moreover, the 7-52 week cohort had significantly higher odds of revision indicated for dislocation (OR: 2.24, P < 0.001), mechanical loosening (OR: 1.71, P < 0.001), PJI (OR: 1.74, P < 0.001), and PPF (OR: 1.96, P < 0.001). CONCLUSIONS Using SSLR, we were successful in identifying two data-driven timing strata between PHF and RTSA that maximized the likelihood of 2-year revision surgery. As it can be difficult to determine whether RTSA or nonoperative management is initially more appropriate, considering the results of this study, an early trial of 4 to 6 weeks of nonoperative management may be appropriate without altering the risks associated with RTSA.

Abstract
Arthroscopic distal clavicle excision (DCE) is a reliable procedure to treat acromioclavicular joint arthritis. Typically, only 1 to 2 cm of distal clavicle should be removed. Resection of too much bone can lead to instability of the joint or lack of support to the shoulder. We describe 2 patients who had excessive clavicular bone removed arthroscopically, leading to irreparable clavicular pain and dysfunction. The 2 female patients, ages 56 and 60 years, presented to our clinic with continued pain after DCE. Both had pain intractable with nonoperative treatment and loss of range of motion of the shoulder. Radiographs revealed a distal clavicle defect of 7.5 cm in 1 patient. The second patient had a 2-cm distal clavicular defect with an adjacent 2-cm clavicle bone fragment between the defect and residual clavicle shaft. Both underwent surgery with subtotal claviculectomy for pain control. During surgery, 1 patient had a subclavian vein requiring vascular repair. After 1 year of follow-up, both patients had reduced but residual pain and restricted range of motion. Only 1 patient could rejoin her preinjury occupation. Neither patient could continue with preinjury recreational sports. Excessive removal of the distal clavicle during DCE can result in continued pain and disability of the shoulder. Methods to visualize the anatomy of the distal clavicle and its articulation to the acromion should be considered when performing this operation arthroscopically. Reoperation to remove subtotal clavicle has good clinical outcomes but may lead to serious complications due to the proximity to major neurovascular structures. [Orthopedics. 2024;47(1):e57-e60.].

Abstract
BACKGROUND Our purpose was to evaluate a custom reverse total shoulder arthroplasty glenoid baseplate for severe glenoid deficiency, emphasizing the challenges with this approach, including short-term clinical and radiographic outcomes and complications. METHODS This was a single-institution, retrospective series of 29 patients between January 2017 and December 2022 for whom a custom glenoid component was created for extensive glenoid bone loss. Patients were evaluated preoperatively and at intervals for up to 5 years. All received preoperative physical examinations, plain radiographs, and computed tomography (CT). Intra- and postoperative complications are reported. RESULTS Of 29 patients, delays resulted in only undergoing surgery, and in three of those, the implant did not match the glenoid. For those three, the time from CT scan to implantation averaged 7.6 months (range, 6.1-10.7 months), compared with 5.5 months (range, 2-8.6 months) for those whose implants fit. In patients with at least 2-year follow-up (n=9), no failures occurred. Significant improvements were observed in all patient-reported outcome measures in those nine patients (American Shoulder and Elbow Score, P<0.01; Simple Shoulder Test, P=0.02; Single Assessment Numeric Evaluation, P<0.01; Western Ontario Osteoarthritis of the Shoulder Index, P<0.01). Range of motion improved for forward flexion and abduction (P=0.03 for both) and internal rotation up the back (P=0.02). Pain and satisfaction also improved (P<0.01 for both). CONCLUSIONS Prolonged time (>6 months) from CT scan to device implantation resulted in bone loss that rendered the implants unusable. Satisfactory short-term radiographic and clinical follow-up can be achieved with a well-fitting device. Level of evidence: III.

Abstract
PURPOSE Dog walking is a popular daily activity, yet information regarding its injury burden is limited. This study describes the epidemiology of injuries related to leash-dependent dog walking among adults presenting to US emergency departments from 2001 to 2020. METHODS A retrospective analysis was performed using the National Electronic Injury Surveillance System database to identify adults (≥18 yr) presenting to US emergency departments with leash-dependent dog walking-related injuries between 2001 and 2020. Outcomes included annual estimates of injury incidence, injury characteristics, and risk factors for sustaining a fracture or traumatic brain injury (TBI). Weighted estimates and 95% confidence intervals (CI) were generated using National Electronic Injury Surveillance System sample weights. RESULTS Between 2001 and 2020, an estimated 422,659 adults presented to US emergency departments with injuries related to leash-dependent dog walking. The annual incidence increased more than fourfold during this period ( n = 7282 vs n = 32,306, P < 0.001). Most patients were women (75%) and adults age 40 to 64 yr (47%), with a mean age of 53 ± 0.5 yr. Patients commonly injured their upper extremity (51%) and were injured while falling when pulled or tripped by the leash (55%). The three most common injuries were finger fracture (6.9%), TBI (5.6%), and shoulder sprain/strain (5.1%). On multivariate analysis, fracture risk among dog walkers was higher in adults age ≥65 yr (odds ratio [OR], 2.1; 95% CI, 1.8-2.5) and women (OR, 1.5; 95% CI, 1.3-1.7). Risk of TBI was also elevated among older dog walkers (OR, 1.6; 95% CI, 1.3-2.0). CONCLUSIONS Dog walking is associated with a considerable and rising injury burden. Dog owners should be informed of this injury potential and advised on risk-reduction strategies.

Abstract
Background This systematic review and network meta-analysis compare clinical outcomes of three different subscapularis management techniques in anatomic total shoulder arthroplasty: lesser tuberosity osteotomy, subscapularis peel, and subscapularis tenotomy. Methods PubMed, Web of Science, Embase, and Cochrane's trial registry were searched in July 2021. Comparative studies and case series evaluating the outcomes of these three techniques were included. The network meta-analysis was performed only on comparative studies. Results Twenty-three studies were included. Both lesser tuberosity osteotomy and subscapularis peel had significantly higher Western Ontario Osteoarthritis Scores compared to subscapularis tenotomy, but no difference in American Shoulder and Elbow Society Scores. Subscapularis peel had superior external rotation compared to lesser tuberosity osteotomy. However, no difference was found in external rotation between subscapularis peel and subscapularis tenotomy or between subscapularis tenotomy and lesser tuberosity osteotomy. The overall weighted average for lesser tuberosity osteotomy bony union was 93.6%, whereas the overall weighted average for subscapularis tendon healing was 79.4% and 87% for subscapularis tenotomy and subscapularis peel, respectively. Discussion This network meta-analysis demonstrated that lesser tuberosity osteotomy and subscapularis peel were associated with the high union and subscapularis healing rates and may be associated with improved shoulder function and quality of life, compared to subscapularis tenotomy. Lesser tuberosity osteotomy and subscapularis peel demonstrate a trend of superior outcomes compared to subscapularis tenotomy during anatomic total shoulder arthroplasty.

Abstract
Background Recurrent shoulder instability is a debilitating condition that can lead to chronic pain, decreased function, and inability to return to activities or sport. This retrospective epidemiology study was performed to report 90-day postoperative complications and costs of Latarjet, anterior bone block reconstruction, arthroscopic, and open Bankart repair for shoulder instability. Methods Patients 18 years and older who underwent four primary shoulder surgeries from 2010 to 2019 were identified using national claims data. Patient demographics, comorbidities, and 90-day postoperative complications were analyzed using univariate analysis and multivariable logistic regression. Total and itemized 90-day reimbursements were determined for each procedure. Results The 90-day medical and surgery-specific complication rates were highest for anterior bone block reconstruction, followed by Latarjet. Arthroscopic Bankart repair had the highest 90-day costs and primary procedure costs compared to other procedures. Conclusion Anterior bone block reconstruction and Latarjet procedures were associated with the highest rates of 90-day medical and surgery-specific complications, while arthroscopic Bankart repair was associated with the highest costs.

Abstract
Background and Objective Reverse shoulder arthroplasty has become a common orthopaedic procedure, with a growing number of cases annually for multiple indications, such as rotator cuff arthropathy, osteoarthritis, or fractures of the proximal humerus, to reduce pain and restore shoulder mobility. Prosthesis design and various recent improvements aim to enhance range of motion (ROM) and stability and to limit component loosening and other potential complications. Many of these well-known issues could theoretically be improved by glenoid, humeral, or combined component lateralization. The objective of this article is to provide an up-to-date literature overview, present available options, and discuss the rationale behind lateralization of certain components, as well as their combined impact on outcomes of reverse shoulder arthroplasty. Methods PubMed and Scopus databases from 2003 to 2023 were searched and screened for studies, including systematic reviews, on the influence of glenoid, humeral, and combined component lateralization that served for narrative review of rationale behind such design. Key Content and Findings Currently, a number of computer simulations, anatomic studies, and limited clinical references aim to support the rationale behind glenoid augmentation, variable humeral neck-shaft angle (NSA), or humeral tray design. Conclusions The utility of lateralization has not yet been clinically established. Randomized, long-term clinical outcome studies are still needed to reach a verdict going beyond surgeon preference and case-specific indications.

Abstract
Background Several classifications have been proposed for subscapularis tendon tearing (SCTs); however, there remains a poor agreement between orthopedic surgeons regarding the diagnosis and management of these lesions. Distinguishing the various tear patterns and classifying them with some prognostic significance may aid the operating surgeon in planning appropriate treatment. Purpose The purpose of this study was to outline the current literature regarding SCT classification and treatment and conduct a survey among shoulder and elbow surgeons to identify the approaches regarding surgical decision-making for these injuries. Methods In this systematic review, we analyzed 12 articles regarding the subscapularis tendon tear classification and implications regarding treatment plans and outcomes. In addition, 4 international experts in subscapularis repair surgery participated in the development of a questionnaire form that was distributed to 1161 ASES members. One hundred sixty five surgeons participated and chose whether they agree, disagree, or abstain for each of the 32 statements in 4 parts including indications/contraindications, treatment plan, and the factors affecting outcomes in the survey. Results Classification criteria were extremely variable with differing recommendations and descriptions of tear morphology; most were based on tear size, associated shoulder pathology, or lesser tuberosity footprint exposure. Considering the multiple classification systems and the overall poor agreement regarding SCT management, our study found that the most widely agreed upon (more than 80%) statements included early surgery is advised for traumatic SCT, chronic degenerative SCT (without fatty infiltration) associated with acute supraspinatus tear is a candidate for repair, and rotator cuff arthropathy is a contraindication for SCT repair. Conclusion Our study was able to identify both patient and tear characteristics that are well agreed upon among surgeons in the treatment of these injuries. Lafosse classification is generally widely accepted; however, it needs to be improved by some additions. Continued collaboration among surgeons is needed to establish an acceptable and broadly applicable classification system for the management of these injuries.

Abstract
In patients with severe glenohumeral osteoarthritis (OA) and preserved rotator cuff function who have failed nonoperative treatment, anatomic total shoulder arthroplasty (TSA) has historically been the preferred surgical treatment. Shoulder arthroplasty in the setting of glenoid bone loss setting is technically demanding. Many techniques have been described to deal with glenoid bone loss including eccentric reaming, bone grafting, augmented glenoid baseplates, and patient-specific implants. Still, the decision to perform anatomic TSA or reverse total shoulder arthroplasty (RTSA) is often unclear, especially as the use of RTSA increases and evolves, making historical studies less useful when considering modern implant designs. RTSA has been advocated as a solution for patients with severe glenoid bone loss with intact rotator cuff function. Moreover, in appropriately selected patients, good outcomes can be achieved without the use of bone grafting or augmented baseplates. In cases of severe glenoid bone loss, RTSA can be performed with reaming the glenoid flat such that the baseplate rests on native glenoid bone. We have previously reported excellent prosthetic survival with this technique at 5-year follow-up. The purpose of this article is to highlight our suggested treatment algorithm for glenohumeral OA with glenoid bone loss and intact rotator cuff. Specifically, we focus on situations where RTSA may be preferred as opposed to anatomic TSA, and our suggested approach to managing bone loss intraoperatively in this complex patient population.

Abstract
We compared the strength of screw vs suture button fixation in the Latarjet procedure for shoulder dislocation through biomechanical testing in a cadaver model. Cadavers were assigned randomly to receive screw or suture button fixation (both groups, n=5). The anteroposterior radius of the glenoid was measured, and a bony defect was created on the anteroinferior rim of the glenoid, equal to 25% of the width of the anteroposterior radius of the glenoid surface. The coracoid process was transferred into the newly created bony defect of the glenoid and fixed with two 3.5-mm partially threaded cannulated screws or 2 surgical buttons. All samples underwent tensile testing in the anteroinferior direction. Statistical analysis was performed to compare mean forces at failure between groups (alpha=.05). The mean force at failure was higher in the screw group (295 N; range, 103-534 N) than in the suture button group (133 N; range, 74-270 N) (P=.045). We found no difference between groups in ability to withstand a force of 150 N, which is the reported mean daily force threshold borne by the shoulder (P=.52). Screw fixation withstood a higher failure load than suture button fixation, indicating that screw fixation is a biomechanically superior option in the Latarjet procedure. The fixation methods did not differ in their ability to withstand the mean force borne by the shoulder during activities of daily living; thus, suture button fixation should be considered as an option in the Latarjet procedure.

Abstract
BACKGROUND The diagnosis of periprosthetic shoulder infection (PSI) in patients with a painful arthroplasty is challenging. Magnetic resonance imaging (MRI) may be helpful, but shoulder implant-induced metal artifacts degrade conventional MRI. Advanced metal artifact reduction (MARS) improves the visibility of periprosthetic bone and soft tissues. The purpose of our study was to determine the reliability, repeatability, and diagnostic performance of advanced MARS-MRI findings for diagnosing PSI. METHODS Between January 2015 and December 2019, we enrolled consecutive patients suspected of having PSI at our academic hospital. All 89 participants had at least 1-year clinical follow-up and underwent standardized clinical, radiographic, and laboratory evaluations and advanced MARS-MRI. Two fellowship-trained musculoskeletal radiologists retrospectively evaluated the advanced MARS-MRI studies for findings associated with PSI in a blinded and independent fashion. Both readers repeated their evaluations after a 2-month interval. Interreader reliability and intrareader repeatability were assessed with κ coefficients. The diagnostic performance of advanced MARS-MRI for PSI was quantified using sensitivity, specificity, and the area under the receiver operating characteristic curve (AUC). When applying the International Consensus Meeting (ICM) 2018 criteria, of the 89 participants, 22 (25%) were deemed as being infected and 67 (75%) were classified as being not infected (unlikely to have PSA and not requiring a surgical procedure during 1-year follow-up). RESULTS The interreader reliability and intrareader repeatability of advanced MARS-MRI findings, including lymphadenopathy, joint effusion, synovitis, extra-articular fluid collection, a sinus tract, rotator cuff muscle edema, and periprosthetic bone resorption, were good (κ = 0.61 to 0.80) to excellent (κ > 0.80). Lymphadenopathy, complex joint effusion, and edematous synovitis had sensitivities of >85%, specificities of >90%, odds ratios of >3.6, and AUC values of >0.90 for diagnosing PSI. The presence of all 3 findings together yielded a PSI probability of >99%, per logistic regression analysis. CONCLUSIONS Our study shows the clinical utility of advanced MARS-MRI for diagnosing PSI when using the ICM 2018 criteria as the reference standard. Although the reliability and diagnostic accuracy were high, these conclusions are based on our specific advanced MARS-MRI protocol interpreted by experienced musculoskeletal radiologists. Investigations with larger sample sizes are needed to confirm these results. LEVEL OF EVIDENCE Diagnostic Level III . See Instructions for Authors for a complete description of levels of evidence.

Abstract
Introduction Avulsion fracture of the ischial tuberosity is uncommon. Patients typically present with symptoms consistent with hamstring strain. The purpose of this case report is to describe an avulsion fracture of the ischial tuberosity and subsequent recovery in an athlete with an endocrine disorder. Case Description A 15-year-old United States of America Gymnastics level 9 gymnast presented with right hamstring pain after regular practice. She had been diagnosed with isolated growth hormone deficiency at age 4 and was treated with growth hormone replacement therapy until age 14. Six months before presentation, she experienced the insidious onset of dull, aching pain in her right hamstring, near the junction of the thigh and buttocks, that was believed to be the result of a chronic hamstring strain. The pain increased gradually over a year and was relieved with rest, massage, and dry needling. Two days before presentation, she felt a "snap" and pain while performing a switch leap during regular practice. She had sharp localized pain in the proximal hamstring with walking and sitting. She was diagnosed with a minimally displaced avulsion fracture of the ischial tuberosity. Outcome With nonoperative treatment, the fracture healed at three months, which is longer than the expected six weeks. Although return to sports is expected three months after this injury, it did not occur until six months in this patient. She was unable to participate in competitive level 9 gymnastics until 12 months after injury. Discussion This case highlights that delayed recovery can occur after avulsion fracture of the ischial tuberosity in adolescent athletes with a history of growth hormone deficiency and treatment using growth hormone.

Abstract
BACKGROUND The most comprehensive health care policy changes aimed at reducing racial disparities were implemented in 2011 and continue today. It is unknown if these initiatives have led to a decrease in racial differences among patients undergoing total shoulder arthroplasty. The purpose of this study is to examine racial differences in procedural rates, complications, and mortality in patients undergoing total shoulder arthroplasty. METHODS National rates of utilization of primary anatomic (TSA) and reverse total shoulder arthroplasty (RTSA) were analyzed from 2012 to 2017. Population-adjusted and gender-adjusted procedural rates were trended over time and standardized based on insurance status. Multivariable logistic regression was used to determine racial differences in complications and mortality. RESULTS In 2012, the incidence of TSA and RTSA among white patients was 18.7/100,000 compared to 5.1/100,000 among black patients (difference: 13.6/100,000) and increased to 36.9/100,000 in white patients and 10.8/100,000 in black patients in 2017 (difference: 26.1/100,000). This equated to an increase in the race disparity by 12.5/100,000 over the study period. Blacks underwent lower rates of TSA and RTSA than whites regardless of insurance status. Black patients had a longer length of hospital stay and a higher rate of discharge to facility. Black patients had increased odds of complications, including acute myocardial infarction (odds ratio [OR] 1.43), pulmonary embolism (OR 1.97), acute renal failure (OR 1.40), sepsis (OR 1.68), and surgical site infection (OR 2.19). Black patients had increased odds of mortality compared with white patients (OR 2.88). CONCLUSION Racial disparities in patients undergoing TSA and RTSA are worsening over time. Black patients undergo TSA and RTSA at lower rates than white patients regardless of insurance status and have increased odds of complications and mortality. Improved initiatives are needed to reduce these racial disparities and further research is warranted to understand their root causes.

Abstract
BACKGROUND The purpose of this study was to determine the incidence of primary reverse total shoulder arthroplasty (RTSA) and anatomic total shoulder arthroplasty (TSA) in the United States and examine changes in age- and sex-based procedure rates. A secondary goal was to determine the incidence of hemiarthroplasty. METHODS Using nationally representative data along with US Census data, we identified >508,000 cases of primary RTSA, anatomic TSA, and shoulder hemiarthroplasty from 2012 to 2017. Trends in the incidence of each procedure were analyzed, and sex- and age-adjusted procedure rates were calculated. RESULTS From 2012 to 2017, the population-adjusted incidence of primary RTSA increased from 7.3 cases per 100,000 persons (22,835 procedures) to 19.3 cases per 100,000 (62,705 procedures); anatomic TSA increased from 9.5 cases per 100,000 (29,685 procedures) to 12.5 cases per 100,000 (40,665 procedures); and hemiarthroplasty decreased from 3.7 cases per 100,000 (11,695 procedures) to 1.5 cases per 100,000 (4930 procedures). These trends were observed among male and female patients, as well as all age groups. The greatest increase in incidence was seen in male patients as well as patients aged 50-64 years undergoing RTSA. CONCLUSION The incidence of primary RTSA and incidence of anatomic TSA have increased substantially in the United States from 2012 to 2017 whereas the incidence of hemiarthroplasty has decreased.

Abstract
Importance The largest US federal action plan to date for reducing racial disparities in health care was implemented in 2011 and continues today. It is not known whether this program, along with other initiatives, is associated with a decrease in racial disparities in the use of major surgical procedures in the US. Objective To analyze whether national initiatives are associated with improvement in racial disparities between White and Black patients in the use of surgical procedures in the US. Design, Setting, and Participants In this case-control study, the national rates of use for 9 major surgical procedures previously shown to have racial disparities in rates of performance between White and Black adult patients (including angioplasty, spinal fusion, carotid endarterectomy, appendectomy, colorectal resection, coronary artery bypass grafting, total hip arthroplasty, total knee arthroplasty, and heart valve replacement) were analyzed from January 1, 2012, through December 31, 2017. Data analysis was conducted from May 1 to June 30, 2020. Population- and sex-adjusted procedural rates during the study period were examined and standardized based on all-payer insurance status. Racial changes were further analyzed by US census division and hospital teaching status for 4 selected procedures: coronary artery bypass grafting, carotid endarterectomy, total hip arthroplasty, and heart valve replacement. Main Outcomes and Measures Population- and race-adjusted procedural rates by year, US census division, hospital teaching status, and insurance status. Results This study included national inpatient data from 2012 to 2017. In 2012, the national incidence rate of all 9 major surgical procedures was higher in White than in Black individuals. For example, the incidence rate of total knee arthroplasty in 2012 for White males was 184.8 per 100 000 persons and for Black males was 79.8 per 100 000 persons. By 2017, these racial disparities persisted for all 9 procedures analyzed. For example, the incidence rate of total knee arthroplasty in 2017 for White males was 220.5 per 100 000 persons and for Black males was 95.6 per 100 000 persons. Although the disparity gap between White and Black patients narrowed for angioplasty (-20.1 per 100 000 persons in males, -4.2 per 100 000 persons in females), spinal fusion (-7.7 per 100 000 persons in males, -15.0 per 100 000 persons in females), carotid endarterectomy (-4.3 per 100 000 persons in males, -4.6 per 100 000 persons in females), appendectomy (-12.3 per 100 000 persons in males, -12.2 per 100 000 persons in females), and colorectal resection (-9.0 per 100 000 persons in males, -12.7 per 100 000 persons in females), the disparity remained constant for coronary artery bypass grafting and widened for 3 procedures, total hip arthroplasty (11.6 per 100 000 persons in males, 20.8 per 100 000 in females), total knee arthroplasty (19.9 per 100 000 persons in males, 12.0 per 100 000 persons in females), and heart valve replacement(12.4 per 100 000 persons in males, 9.2 per 100 000 persons in females). In 2017, racial differences persisted in all US census divisions and in both urban teaching and urban nonteaching hospitals. When rates were adjusted based on insurance status, Black patients with Medicare, Medicaid, and private insurance underwent lower rates of all procedures analyzed compared with White patients. For example, rate of spinal fusion in Black patients was 70.2% of the rate in White patients with Medicare, 56.5% to that of White patients with Medicaid, and 61.2% to that of White patients with private insurance. Conclusions and Relevance Results of this study suggest that despite national initiatives, racial disparities have persisted for all analyzed procedures and worsened for one-third of the analyzed procedures. These disparities were evident regardless of US census division, hospital teaching status, or insurance status. Renewed initiatives to help diminish racial disparities and improve health care equality are warranted.

Abstract
BACKGROUND Tranexamic acid efficacy on clinically relevant adverse outcomes in patients undergoing shoulder arthroplasty has been contradictory. The aim of this review was to analyze whether tranexamic acid administration could decrease transfusions, infection and hematoma formation in patients undergoing shoulder arthroplasty. METHODS PubMed, EMBASE, and the Cochrane Library were searched up to May 2019 for randomized controlled trials comparing tranexamic acid to placebo in shoulder arthroplasty. Random-effect models were performed to meta-analyze the evidence. Trial sequential analysis was used to calculate and to establish the conclusiveness of the evidence derived from the meta-analysis. RESULTS Four randomized controlled trials comprising 375 patients were included. Meta-analysis showed no effect of tranexamic acid on transfusion rate (RR = 0.48 (adjusted 95% CI 0.05 to 3.85)). The possible effect of tranexamic acid on hematoma formation or infection rates after shoulder arthroplasty is non-estimable with the current evidence. The sample size necessary to reliably determine if tranexamic acid decreases transfusions, infection rates and hematoma formation is not available from the current literature as determined by the trial sequential analysis. DISCUSSION While tranexamic acid has proven its efficacy in decreasing blood loss in shoulder arthroplasty, this meta-analysis of randomized controlled trials clarifies that there is currently no conclusive evidence for a positive effect of tranexamic acid upon transfusion rate, infection rates or hematoma formation in patients undergoing primary shoulder arthroplasty.

Abstract
BACKGROUND To help control the coronavirus disease 2019 pandemic, elective procedures have been cancelled in most US hospitals by government order. The purpose of this study is to estimate national hospital reimbursement and net income losses owing to elective surgical procedure cancellation during the coronavirus disease 2019 pandemic. METHODS The National Inpatient Sample and the Nationwide Ambulatory Surgery Sample were used to identify all elective surgical procedures performed in the inpatient setting and in hospital-owned outpatient surgery departments throughout the United States. Total cost, reimbursement, and net income was determined for all elective surgical procedures. RESULTS The estimated total annual cost of elective inpatient and outpatient surgical procedures in the United States was $147.2 billion, and estimated total hospital reimbursement was $195.4 to $212.2 billion. This resulted in a net income of $48.0 to $64.8 billion per year to the US hospital system. Cancellation of all elective procedures would result in estimated losses of $16.3 to $17.7 billion per month in revenue and $4 to $5.4 billion per month in net income to US hospitals. CONCLUSION Cancellation of elective procedures during the coronavirus disease 2019 pandemic has a substantial economic impact on the US hospital system.

Abstract
Few studies report on periprosthetic humeral shaft fractures after reverse total shoulder arthroplasty (RTSA). The authors evaluated outcomes of 5 patients with this complication who were initially treated nonoperatively. Of 152 patients who underwent RTSA at the authors' institution from 2012 to 2017, 4 experienced periprosthetic humeral shaft fractures. One patient was referred to the authors for fracture treatment. All 5 patients were initially treated nonoperatively. The mean duration of follow-up was 11.5 months (range, 1.5-26 months). The authors analyzed time to fracture union, Single Assessment Numeric Evaluation (SANE) score, visual analog scale (VAS) score for pain, and active shoulder range of motion. Fracture union occurred in 4 patients treated nonoperatively at a mean of 4.4 months. Mean SANE score was 55 of 100 (range, 20-85). Mean VAS score was 3.4 of 10 (range, 0-8). Mean forward elevation was 83° (range, 45°-110°); mean abduction was 65° (range, 45°-80°); and mean external rotation with the arm at the side was 15° (range, 0°-30°). Many factors must be considered when customizing treatment for patients with periprosthetic fracture after RTSA. This case series indicates that nonoperative treatment of postoperative periprosthetic humeral shaft fractures can be successful. [Orthopedics. 2020;43(6):e553-e560.].

Abstract
BACKGROUND Minimal clinically important differences (MCIDs) at 1 year after subpectoral biceps tenodesis are unknown for the American Shoulder and Elbow Surgeons (ASES) scale, Subjective Shoulder Value (SSV), and visual analog scale (VAS) for pain. Our objectives were to determine MCIDs for these measures at 1 year after biceps tenodesis and to identify preoperative factors that predict attainment of MCIDs. METHODS We included 52 patients who underwent arthroscopic débridement, decompression, and mini-open biceps tenodesis from 2016-2018. We analyzed age, sex, body mass index value, arm dominance, diagnosis, range of shoulder motion, and preoperative and 1-year postoperative ASES, SSV, and VAS scores. MCIDs were calculated using a distribution-based method of one-half the standard deviation. Preoperative thresholds predictive of MCIDs were calculated with univariate logistic regression. Multiple logistic regression was used to determine factors that predict MCIDs. Significance was set at a 2-tailed P value of <.05. RESULTS MCIDs for the ASES, SSV, and VAS were 13, 12, and 1.6 points, respectively. Preoperative ASES score <59 predicted MCID on the ASES (P = .03); VAS score >3 predicted MCID on the VAS (P < .01); external shoulder rotation >40° predicted MCID on the SSV (P = .02); and age >41 years predicted MCID on the VAS (P = .02). CONCLUSION At 1 year after débridement, decompression, and biceps tenodesis, MCIDs were 13, 12, and 1.6 points for the ASES, SSV, and VAS, respectively. Patients most likely to attain MCIDs were those aged >41 years, those with the most preoperative pain, and those with the poorest preoperative shoulder function.

Abstract
Kayaking has become one of the most popular paddle sports throughout the world. The shoulder is the most commonly injured area of the body among kayaking participants as a result of acute traumatic events and chronic overuse injuries. Therefore, kayaking participants may often seek advice for shoulder problems and there is a scarcity of studies regarding shoulder injuries in this population. In this case report, we present a young male recreational whitewater kayaker with a severe suprascapular nerve (SSN) entrapment who presented with shoulder pain and inability to perform his sport. He was initially evaluated elsewhere and was treated with nonsteroidal anti-inflammatory medications and physical therapy for presumptive diagnosis of subacromial impingement. After 5 months of failed non-operative treatment, the patient sought a second opinion with our group. SSN entrapment diagnosis was confirmed by a thorough careful physical examination, magnetic resonance imaging and electrodiagnostic study. Given the failure of non-operative treatment, the patient was treated with arthroscopic SSN decompression and successfully returned to kayaking without symptoms. While SSN entrapment has been reported in a variety of sports, especially those involving overhead movements, this is the first case report of SSN entrapment reported which impaired participation in kayaking. This case report supports the consideration of SSN entrapment in the differential diagnosis of painful shoulder among kayaking participants and highlights the importance of undressing the patient and examining the posterior shoulder for atrophy, winging or deformity.

Abstract
BACKGROUND Despite the increasing use of biceps tenodesis, there is a lack of consensus regarding optimal implant choice (suture anchor vs interference screw) and implant placement (suprapectoral vs subpectoral). PURPOSE/HYPOTHESIS The purpose was to determine the associations of procedural parameters with the biomechanical performance of biceps tenodesis constructs. The authors hypothesized that ultimate failure load (UFL) would not differ between sub- and suprapectoral repairs or between interference screw and suture anchor constructs and that the number of implants and number of sutures would be positively associated with construct strength. STUDY DESIGN Meta-analysis. METHODS The authors conducted a systematic literature search for studies that measured the biomechanical performance of biceps tenodesis repairs in human cadaveric specimens. Two independent reviewers extracted data from studies that met the inclusion criteria. Meta-regression was then performed on the pooled data set. Outcome variables were UFL and mode of failure. Procedural parameters (fixation type, fixation site, implant diameter, and numbers of implants and sutures used) were included as covariates. Twenty-five biomechanical studies, representing 494 cadaveric specimens, met the inclusion criteria. RESULTS The use of interference screws (vs suture anchors) was associated with a mean 86 N-greater UFL (95% CI, 34-138 N; P = .002). Each additional suture used to attach the tendon to the implant was associated with a mean 53 N-greater UFL (95% CI, 24-81 N; P = .001). Multivariate analysis found no significant association between fixation site and UFL. Finally, the use of suture anchors and fewer number of sutures were both independently associated with lower odds of native tissue failure as opposed to implant pullout. CONCLUSION These findings suggest that fixation with interference screws, rather than suture anchors, and the use of more sutures are associated with greater biceps tenodesis strength, as well as higher odds of native tissue failure versus implant pullout. Although constructs with suture anchors show inferior UFL compared with those with interference screws, incorporation of additional sutures may increase the strength of suture anchor constructs. Supra- and subpectoral repairs provide equivalent biomechanical strength when controlling for potential confounders.

Abstract
Compared with other joints in the body, examination of the shoulder continues to be a challenge for practitioners, whether they be trainers, physical therapists, primary care physicians, or orthopedic surgeons. There are many reasons for this challenge, the primary being the highly complex architecture of bony and soft-tissue anatomy which allows for the greatest range of motion of any joint of the body. As a result, the clinical examination as Ralph Hertel, MD, has commented "perhaps it is just not easy." His comment reflects that one cannot just expect to understand how to interpret the examination unless the observer has some knowledge of how the shoulder complex works, how to perform the basics of the examination, how to interpret radiographs, and how to integrate these variables into a diagnosis. This chapter will attempt to delineate the principles which make the shoulder examination more attainable, plus highlight the areas where a combination of factors is necessary to arrive at a diagnosis.

Abstract
Background Reverse total shoulder arthroplasty (RTSA) can lead to limited postoperative internal rotation (IR). We assessed how IR is measured and reported in the RTSA literature and examined the relationships between these measures and patient-reported ability to perform activities of daily living. Methods We searched MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials for articles published in English from January 2000 through September 2018 that reported clinical outcomes after RTSA (minimum 12-month follow-up). We included studies reporting IR range of motion (ROM) and/or patient-reported functional outcomes related to IR. We identified 255 studies, 35% of which were excluded because they reported no IR outcome measures, leaving 165 studies for analysis. Results Studies reported 3 methods of measuring IR ROM: (1) vertebral level (VL) method (ie, the most proximal VL reached by the extended thumb with the arm behind the back), (2) degrees of IR with the arm abducted to 90°, and (3) degrees of IR with the arm in a neutral position. The VL measurement was reported in 89% of studies, but the methods of reporting this measure varied. Only 9% of studies reported functional outcomes related to IR. No study correlated clinical measurements of IR ROM with functional outcomes. Conclusions Measures and reporting of shoulder IR after RTSA varied widely. This variability makes it difficult to assess associations between postoperativce IR limitation and functional abilities. Standardization of IR measures and reporting is needed to allow meta-analysis of data related to this important outcome.

Abstract
Background This study aimed to determine the toileting ability (TA) of patients undergoing primary reverse total shoulder arthroplasty (RTSA) and identify factors associated with TA postoperatively. Methods A questionnaire regarding toileting was administered to 119 patients who underwent primary RTSA with a minimum 1-year follow-up. Patients were separated into 2 groups based on whether the arm that underwent RTSA was the one used for toileting (study group, n = 74) or not (control group, n = 45). Patient-reported TA was calculated both before and after RTSA. Multivariate analysis was performed to identify factors associated with TA postoperatively. Results Impairment in TA before RTSA was higher in the study group and affected almost three-quarters of the patients (72%). In the study group, primary RTSA resulted in a statistically significant improvement in TA (P < .001), and no difference in TA was found between groups after RTSA (P = .076). Postoperatively, 92% of the patients in the study group were able to manage toileting with the involved extremity (54% without difficulty and 38% with some degree of difficulty). Only 1 patient (1.3%) was totally unable to manage toileting with either arm postoperatively. The patients at risk of toileting difficulties postoperatively were those who had preoperative toileting difficulties and lower postoperative internal rotation range of motion. Conclusions Over 90% of patients can manage toileting after primary RTSA, and total toileting inability is rare after the procedure (1.3%). Patients should be counseled that after primary RTSA, they have a high probability of being able to manage toileting with independence even if it is with some difficulty.

Abstract
When performing diagnostic and surgical arthroscopic procedures on the shoulder, the importance of patient positioning cannot be understated. The optimum patient positioning for shoulder arthroscopy should enhance intraoperative joint visualization and surgical accessibility while minimizing potential perioperative risk to the patient. Most shoulder arthroscopy procedures can be reliably performed with the patient either in the lateral decubitus (LD) or beach chair (BC) position. Although patient positioning for shoulder arthroscopy has been subject of controversy, there is no conclusive evidence to suggest superiority of one position versus another. Each position offers advantages and disadvantages and surgeon's experience and training are pivotal on selecting one position versus another. Regardless of the position, a proper positioning of the patient should provide adequate access to the joint while minimizing complications. The purpose of this review is to summarize setup and technical aspects, the advantages and disadvantages, and the possible complications of the LD and BC positions in shoulder arthroscopy.

Abstract
Ulnar collateral ligament (UCL) tears can occur from trauma or chronic overuse, and the treatment depends on the type of sport the patient plays and the severity of symptoms. Overuse UCL injuries are most commonly due to micro-trauma in overhead athletes such as baseball players, softball players, and tennis players. Acute complete UCL tears in athletes due to trauma are less common but generally operative treatment is recommended. In gymnastics, elbow dislocations are more common than isolated UCL injuries, and there is sparse literature on the success of non-operative treatment of isolated UCL injuries in this group of athletes. In this case report, we report a high-level competitive gymnast with an UCL tear and a partial tear of the forearm flexor mass, which was confirmed by a thorough careful physical examination and magnetic resonance imaging. The patient was treated non-operatively and successfully returned to gymnastics without symptoms. This case supports the suggestion that UCL tears of the elbow can be treated successfully in some gymnasts without surgery, and that treatment should be individualized in this group of athletes.

Abstract
BACKGROUND Biomechanical cadaveric studies of rotator cuff repair (RCR) have shown that transosseous equivalent and double-row anchored repairs are stronger than other repair constructs. PURPOSE To identify technical and procedural parameters that most reliably predict biomechanical performance of RCR constructs. STUDY DESIGN Systematic review. METHODS The authors systematically searched the EMBASE and PubMed databases for biomechanical studies that measured RCR performance in cadaveric specimens. The authors performed a meta-regression on the pooled data set with study outcomes (gap formation, failure mode, and ultimate failure load) as dependent variables and procedural parameters (eg, construct type, number of suture limbs) as covariates. Stratification by covariates was performed. An alpha level of .05 was used. RESULTS Data from 40 eligible studies were included. Higher number of suture limbs correlated with higher ultimate failure load (β = 38 N per limb; 95% CI, 28 to 49 N) and less gap formation (β = -0.6 mm per limb; 95% CI, -1 to -0.2 mm). Other positive predictors of ultimate failure load were number of sutures, number of mattress stitches, and use of wide suture versus standard suture. When controlling for number of suture limbs, we found no significant differences among single-row anchored, double-row anchored, transosseous equivalent, and transosseous repairs. Higher number of suture limbs and transosseous equivalent repair both increased the probability of catastrophic construct failure. CONCLUSION This study suggests that the number of sutures, suture limbs, and mattress stitches in a RCR construct are stronger predictors of overall strength than is construct type. There is a need to balance increased construct strength with higher risk of type 2 failure.

Background It has been suggested that, during primary shoulder arthroplasty, surgeons should identify the axillary nerve through direct visualization, palpation, or the “tug test” to prevent iatrogenic nerve injury. Our goal was to document the rate of isolated axillary nerve injury (IANI) in patients who had undergone primary anatomic total shoulder arthroplasty (TSA) or reverse total shoulder arthroplasty (RTSA) without routine identification of the axillary nerve. Methods Data on 869 cases of primary shoulder arthroplasty (338 TSAs and 531 RTSAs) performed by 1 surgeon between 2003 and 2017 were reviewed. Neither the tug test nor identification of the axillary nerve through palpation or visualization was used in any case. The primary outcome was new IANI documented within 3 months after arthroplasty. The frequency of IANI was summarized using point estimates and 95% confidence intervals (CIs). Results Six cases met the criteria for IANI. The overall incidence of IANI was 0.7% (95% CI, 0.3%-1.4%). The incidence of IANI was 0.3% (95% CI, 0%-1.6%) after TSA and 0.9% (95% CI, 0.3%-2.1%) after RTSA. All IANIs were cases of neurapraxia, and all patients had experienced complete neurologic recovery at last follow-up. Conclusion Complete, permanent IANI resulting from direct surgical trauma during primary shoulder arthroplasty can be avoided without using the tug test or routine identification of the nerve. A low incidence of partial temporary IANI can be expected, which may be related to indirect traction injuries.

Abstract
Orthopaedic procedures can affect patients' ability to perform activities of daily living, such as driving automobiles or other vehicles that require coordinated use of the upper and lower extremities. Many variables affect the time needed before a patient can drive competently after undergoing orthopaedic surgery to the extremities. These variables include whether the patient underwent upper or lower extremity surgery, the country in which the patient resides, whether the right or left lower extremity is involved, whether the dominant arm is involved, whether the extremity is in a cast or brace, whether the patient has adequate strength to control the steering wheel, and whether the patient is taking pain medication. The type and complexity of the procedure also influence the speed of return of driving ability. Few studies provide definitive data on driving ability after upper or lower extremity surgery. Patients should be counseled not to drive until they can control the steering wheel and the pedals competently and can drive well enough to prevent further harm to themselves or to others. This review discusses the limited recommendations in the literature regarding driving motorized vehicles after upper or lower extremity orthopaedic surgery.

Abstract
Knowledge of the pertinent anatomy, pathogenesis, clinical presentation and treatment of the spectrum of injuries involving the superior glenoid labrum and biceps origin is required in treating the patient with a superior labrum anterior and posterior (SLAP) tear.Despite the plethora of literature regarding SLAP lesions, their clinical diagnosis remains challenging for a number of reasons.First, the diagnostic value of many of the available physical examination tests is inconsistent and ambiguous.Second, SLAP lesions most commonly occur concomitantly with other shoulder injuries.Third, SLAP lesions have no specific associated pain pattern.Outcomes following surgical treatment of SLAP tears vary depending on the method of treatment, associated pathology and patient characteristics.Biceps tenodesis has been receiving increasing attention as a possible treatment for SLAP tears.

Abstract
OBJECTIVE To provide certified athletic trainers (ATs) with recommendations and guidelines for the immediate management of patients with joint dislocations. BACKGROUND One of the primary responsibilities of ATs is to provide immediate injury care for active individuals. Although ATs are confronted with managing patients who have many kinds of injuries, the onsite management of a joint dislocation presents challenges in evaluation and immediate treatment. The critical concern in managing a dislocation is deciding when a joint can be reduced onsite and when the patient should be splinted and transported for reduction to be performed in the hospital or medical setting. Factors that influence the decision-making process include the following: whether the AT possesses a documented protocol that is supported by his or her supervising physician(s), employer documents, and respective state regulations; the AT's qualifications and experience; the dislocated joint; whether the dislocation is first time or recurrent; the patient's age and general health; and whether associated injuries are present. RECOMMENDATIONS These guidelines are intended to provide considerations for the initial care of specific joint dislocations. They are not intended to represent the standard of care and should not be interpreted as a standard of care for therapeutic or legal discussion.

Abstract
BACKGROUND Aseptic glenoid baseplate loosening (AGBL) is a catastrophic complication after reverse total shoulder arthroplasty (RTSA). Our goals were to determine the incidence of AGBL in patients who underwent RTSA and identify risk factors for AGBL after RTSA. METHODS We analyzed 202 shoulders that underwent primary or revision RTSA using 1 implant system and evaluated baseplate loosening at a minimum 2-year follow-up. The associations between AGBL and the following variables were investigated: patient age, sex, primary vs. revision RTSA, scapular notching, use of bone graft, and type of baseplate screw fixation. RESULTS AGBL occurred in 6 shoulders (3.0%). The incidence of AGBL after revision RTSA (10%) was significantly higher than that after primary RTSA (1.2%; P = .014). There were significant associations between AGBL and the use of bone graft and the use of nonlocking screws. Scapular notching, glenosphere center-of-rotation offset, patient age, and sex were not associated with AGBL. Multiple logistic regression analysis showed that the use of all peripheral nonlocking 3.5-mm screws (odds ratio, 10.6; 95% confidence interval, 1.1- 39) and the use of bone graft (odds ratio, 7.5; 95% confidence interval, 1.9-30) were independent risk factors for AGBL. CONCLUSIONS The rate of baseplate failure after primary RTSA is low (1.2%) but is significantly higher after revision RTSA (10%). Major risk factors for baseplate failure are the use of all 3.5-mm nonlocking screws for peripheral baseplate fixation and the use of a bone graft to address deficiencies in bony support beneath the baseplate.

Abstract
BACKGROUND Our aim was to evaluate complications related to commercially available antibiotic cement spacers used in the treatment of shoulder infections. METHODS We performed a retrospective review of commercially available antibiotic spacers implanted in 53 patients (60 spacers) between April 2009 and October 2017 as part of a 2-stage treatment plan for infection at the site of a shoulder arthroplasty (n = 39), other (non-arthroplasty) shoulder surgery (n = 8), or primary shoulder infection without previous surgery (n = 6). All patients were followed up from spacer placement to second-stage revision to shoulder arthroplasty. Ten patients retained the spacers and were followed up for a minimum of 1 year. RESULTS No complications were associated with implantation of the spacers. Of the 44 patients (50 spacers) who underwent a second-stage revision after a mean interval of 6 months (range, 2-18 months), 14 patients had 18 complications. Fourteen complications occurred between implantation and removal. The most common complication was bone erosion (6 in the glenoid and 2 in the humeral shaft). Other complications were fractures of the spacer (n = 4), spacer rotation (n = 3), and humeral fracture (n = 3). Two complications required reoperation. There were 4 spacer-related complications among the 10 patients who retained the implant (3 erosions of the humeral shaft and 1 humeral shaft fracture); none required reoperation or removal. CONCLUSIONS Complications related to antibiotic spacers are common especially between the first and second stage of revision, and awareness of these complications is important for the treating provider.

Abstract
OBJECTIVE To present recommendations for the diagnosis, management, outcomes, and return to play of athletes with superior labral anterior-posterior (SLAP) injuries. BACKGROUND In overhead athletes, SLAP tears are common as either acute or chronic injuries. The clinical guidelines presented here were developed based on a systematic review of the current evidence and the consensus of the writing panel. Clinicians can use these guidelines to inform decision making regarding the diagnosis, acute and long-term conservative and surgical treatment, and expected outcomes of and return-to-play guidelines for athletes with SLAP injuries. RECOMMENDATIONS Physical examination tests may aid diagnosis; 6 tests are recommended for confirming and 1 test is recommended for ruling out a SLAP lesion. Combinations of tests may be helpful to diagnose SLAP lesions. Clinical trials directly comparing outcomes between surgical and nonoperative management are absent; however, in cohort trials, the reports of function and return-to-sport outcomes are similar for each management approach. Nonoperative management that includes rehabilitation, nonsteroidal anti-inflammatory drugs, and corticosteroid injections is recommended as the first line of treatment. Rehabilitation should address deficits in shoulder internal rotation, total arc of motion, and horizontal-adduction motion, as well as periscapular and glenohumeral muscle strength, endurance, and neuromuscular control. Most researchers have examined the outcomes of surgical management and found high levels of satisfaction and return of shoulder function, but the ability to return to sport varied widely, with 20% to 94% of patients returning to their sport after surgical or nonoperative management. On average, 55% of athletes returned to full participation in prior sports, but overhead athletes had a lower average return of 45%. Additional work is needed to define the criteria for diagnosing and guiding clinical decision making to optimize outcomes and return to play.

Abstract
Despite advancements in surgical technique and understanding of throwing mechanics, controversy persists regarding the treatment of grade III acromioclavicular (AC) joint separations, particularly in throwing athletes. Twenty-eight major league baseball (MLB) orthopedic team physicians were surveyed to determine their definitive management of a grade III AC separation in the dominant arm of a professional baseball pitcher and their experience treating AC joint separations in starting pitchers and position players. Return-to-play outcomes were also evaluated. Twenty (71.4%) team physicians recommended nonoperative intervention compared to 8 (28.6%) who would have operated acutely. Eighteen (64.3%) team physicians had treated at least 1 professional pitcher with a grade III AC separation; 51 (77.3%) pitchers had been treated nonoperatively compared to 15 (22.7%) operatively. No difference was observed in the proportion of pitchers who returned to the same level of play (P = .54), had full, unrestricted range of motion (P = .23), or had full pain relief (P = .19) between the operatively and nonoperatively treated MLB pitchers. The majority (53.6%) of physicians would not include an injection if the injury was treated nonoperatively. Open coracoclavicular reconstruction (65.2%) was preferred for operative cases; 66.7% of surgeons would also include distal clavicle excision as an adjunct procedure. About 90% of physicians would return pitchers to throwing >12 weeks after surgery compared to after 4 to 6 weeks in nonoperatively treated cases. In conclusion, MLB team physicians preferred nonoperative management for an acute grade III AC joint separation in professional pitchers. If operative intervention is required, ligament reconstruction with adjunct distal clavicle excision were the most commonly performed procedures.

Abstract
PURPOSE A major concern for patients undergoing reverse total shoulder arthroplasty (RTSA) is managing toileting after surgery. The goals of this systematic review of RTSA studies were to determine the following: (1) the percentage of patients who can manage toileting, (2) their degree of difficulty with toileting, and (3) the percentage of patients who can manage toileting after bilateral versus unilateral RTSA. METHODS Medline, EMBASE, Google Scholar, and the Cochrane Central Register of Controlled Trials were searched for studies reporting the ability to manage toileting after RTSA. Six studies with at least 12 months of follow-up were included, yielding 183 patients (105 unilateral RTSA, 78 bilateral RTSA). We pooled patient data and calculated the weighted mean proportion of patients able to manage toileting, those who reported difficulty, and those able to manage toileting after unilateral versus bilateral RTSA. Statistical significance was set at P < 0.05. RESULTS Most patients (92%; 95% confidence interval, 87-95%) were able to manage toileting after RTSA. Some degree of difficulty with toileting was reported for 20% of all shoulders. Almost all patients with bilateral RTSA were able to manage toileting with at least one arm (weighted mean proportion 97%; 95% confidence interval, 88-99%). There was no significant difference in the proportion of patients able to manage toileting after unilateral versus bilateral RTSA (P = 0.08). Only 3% of all papers published on the clinical results of RTSA by June 2017 reported upon toileting after the procedure. CONCLUSIONS With the available evidence, most patients were able to manage toileting after RTSA, although one-fifth reported some degree of difficulty. Ability to manage toileting was similar after unilateral versus bilateral RTSA. In the future, this variable should be a standard question after shoulder arthroplasty. LEVEL OF EVIDENCE IV.
