Abstract
BACKGROUND Mixed reality may offer an alternative for computer-assisted navigation in shoulder arthroplasty. The purpose of this study was to determine the accuracy and precision of mixed-reality guidance for the placement of the glenoid axis pin in cadaver specimens. This step is essential for accurate glenoid placement in total shoulder arthroplasty. METHODS Fourteen cadaveric shoulders underwent simulated shoulder replacement surgery by 7 experienced shoulder surgeons. The surgeons exposed the cadavers through a deltopectoral approach and then used mixed-reality surgical navigation to insert a guide pin in a preplanned position and trajectory in the glenoid. The mixed-reality system used the Microsoft Hololens 2 headset, navigation software, dedicated instruments with fiducial marker cubes, and a securing pin. Computed tomography scans obtained before and after the procedure were used to plan the surgeries and determine the difference between the planned and executed values for the entry point, version, and inclination. One specimen had to be discarded from the analysis because the guide pin was removed accidentally before obtaining the postprocedure computed tomography scan. RESULTS Regarding the navigated entry point on the glenoid, the mean difference between planned and executed values was 1.7 ± 0.8 mm; this difference was 1.2 ± 0.6 mm in the superior-inferior direction and 0.9 ± 0.8 mm in the anterior-posterior direction. The maximum deviation from the entry point for all 13 specimens analyzed was 3.1 mm. Regarding version, the mean difference between planned and executed version values was 1.6° ± 1.2°, with a maximum deviation in version for all 13 specimens of 4.1°. Regarding inclination, the mean angular difference was 1.7° ± 1.5°, with a maximum deviation in inclination of 5°. CONCLUSIONS The mixed-reality navigation system used in this study allowed surgeons to insert the glenoid guide pin on average within 2 mm from the planned entry point and within 2° of version and inclination. The navigated values did not exceed 3 mm or 5°, respectively, for any of the specimens analyzed. This approach may help surgeons more accurately place the definitive glenoid component.

Abstract
In this era of subspecialty care in orthopedics, iterations of implant design can occur in a silo which then precludes gaining knowledge from failures of implant design that may have occurred in different subspecialties. This literature review describes the history of failures in hip and shoulder arthroplasties with the purpose of identifying similar factors that led to previous implant failures. A review of the literature was performed by two reviewers assessing articles that described failed hip and shoulder arthroplasty systems over time. We identified and analyzed 53 implant failures-23 in hip arthroplasty and 30 in shoulder arthroplasty. These failures were categorized as material, mechanical, and technical. In hip arthroplasty, 48% were material, 39% mechanical, and 13% technical failures. In shoulder arthroplasty, the distribution was 10% material, 70% mechanical, and 20% technical failures. The distribution of these failures highlights similar and sometimes repeated failure mechanisms between subspecialties. This accentuates the importance of a collaborative approach to improve future arthroplasty designs.

Abstract
Treatment of a comminuted proximal humerus fracture (PHF) in elderly patients with severe osteoporosis is challenging, often leading to arthroplasty (such as hemiarthroplasty or reverse shoulder arthroplasty) as the treatment of choice. However, arthroplasty does not always guarantee favorable outcomes. In contrast, the use of intramedullary fibular strut allografts provides additional reduction stability during locking plate fixation; however, to our knowledge, there is limited literature on the use of fibular strut allografts, including the fibular head. Here we aim to report the advantages of using a fibular strut containing the fibular head in severe osteoporotic PHFs. We present the case of an 88-year-old female patient with severe osteoporosis diagnosed with a left PHF accompanied by severe metaphyseal comminution following a fall from a chair. Rather than shoulder arthroplasty, we performed osteosynthesis using a fibular strut allograft containing the fibular head. At the one-year follow-up after surgery, we observed excellent bony union and a favorable functional outcome without major complications, such as reduction loss. The novel use of a fibular strut allograft containing the fibular head could be promising for PHFs with severe metaphyseal comminution, potentially avoiding the need for arthroplasty.

Abstract
BACKGROUND As the number of total shoulder arthroplasty (TSA) procedures increases, there is a growing interest in improving patient outcomes, limiting costs, and optimizing efficiency. One approach has been to transition these surgeries to an outpatient setting. Therefore, the purpose of this study was to conduct an age-stratified analysis comparing the 90-day postoperative outcomes of primary TSA in the same-day discharge (SDD) and inpatient (IP) settings with a specific focus on the super-elderly. METHODS This retrospective study included all patients who underwent primary anatomic or reverse TSA between January 2018 and December 2021 in ambulatory and inpatient settings. The outcome measures included LOS, complications, hospital charges, ED utilization, readmissions, and reoperations within 90-days following TSA. Patients with LOS ≤8 hours were considered as SDD, and those with LOS >8 hours were considered as IP. P <0.05 was considered statistically significant. RESULTS There were 121 and 174 procedures performed in SDD and IP settings, respectively. There were no differences in comorbidity indices between the SDD and IP groups (ASA score P=0.12, ECI P=0.067). The SDD cohort was younger than the IP group (SDD 67.0 years vs. 73.0 IP years, P<0.001), and the SDD group higher rate of intraoperative tranexamic acid use (P=0.015) and lower estimated blood loss (P=0.009). There were no differences in 90-day overall minor (P=0.20) and major complications (P=1.00), ED utilization (P=0.63), readmission (P=0.25) or reoperation (P =0.51) between the SDD and IP groups. When stratified by age, there were no differences in overall major (P=0.80) and minor (P=0.36) complications among the groups. However, the LOS was directly correlated with increasing age (LOS=8.4 hours in ≥65 to < 75-year cohort vs. LOS=25.9 hours in ≥80-year cohort; P<0.001). There were no differences in hospital charges between SDD and IP primary TSA in all 3 age groups (P=0.82). CONCLUSION SDD TSA has a shorter LOS without increasing postoperative major and minor complications, ED encounters, readmissions, or reoperations. Older age was not associated with an increase in the complication profile or hospital charges even in the SDD setting, although it was associated with increased LOS in the IP group. These results suggest that TSA can be safely performed expeditiously in an outpatient setting. LEVEL OF EVIDENCE Level III; Retrospective Comparative Study.

Abstract
BACKGROUND Cutibacterium acnes is the bacterium most commonly responsible for shoulder periprosthetic joint infection (PJI) and is often cultured from samples obtained at the time of revision for failed shoulder arthroplasty. We sought to determine whether these bacteria originate from the patient or from exogenous sources. We also sought to identify which C. acnes genetic traits were associated with the development of shoulder PJI. METHODS We performed bacterial whole-genome sequencing of C. acnes from a single-institution repository of cultures obtained before or during primary and revision shoulder arthroplasty and correlated the molecular epidemiology and genetic content of strains with clinical features of infection. RESULTS A total of 341 isolates collected over a four-year period from 88 patients were sequenced. C. acnes cultured from surgical specimens demonstrated significant similarity to the strains colonizing the skin of the same patient (p<0.001). Infrequently, there was evidence of strains shared across unrelated patients, suggesting that exogenous sources of C. acnes culture-positivity were uncommon. Phylotypes IB and II were modestly associated with clinical features of PJI, but all phylotypes appeared inherently capable of causing disease. Chronic shoulder PJI was associated with the absence of common C. acnes genes involved in bacterial quorum-sensing (luxS, tqsA). CONCLUSION C. acnes strains cultured from deep intraoperative sources during revision shoulder arthroplasty demonstrate strong genetic similarity to the strains colonizing a patient's skin. Some phylotypes of C. acnes commonly colonizing human skin are modestly more virulent than others, but all phylotypes have a capacity for PJI. C. acnes cultured from cases of PJI commonly demonstrated genetic hallmarks associated with adaptation from acute to chronic phases of infection. This is the strongest evidence to date supporting the role of the patient's own, cutaneous C. acnes strains in the pathogenesis of shoulder arthroplasty infection. Our findings support the importance of further research focused on perioperative decolonization and management of endogenous bacteria that are likely to be introduced into the arthroplasty wound at the time of skin incision.

Abstract
INTRODUCTION Allograft prosthetic composite (APC) reconstruction is performed after resection of proximal humerus tumors or failure of arthroplasty implants. There is limited literature on the postoperative outcomes of this technique. We sought to assess implant survival, failure rates, and postoperative functional outcomes after APC reconstruction of the proximal humerus. METHODS A systematic review of the PubMed and Embase databases was conducted. The study was registered on PROSPERO (ID: 448663). The STROBE checklist was used for quality assessment. Implant failure was determined using the Henderson classification for biological reconstruction. Functional outcome was primarily assessed using the Musculoskeletal Tumor Society (MSTS) score at last follow-up. RESULTS Twenty-five studies with a total of 488 patients were included. Mean follow-up in reporting studies ranged from 2.5 to 10 years. Five-year revision-free survival for implants ranged from 41 to 92%. Overall implant failure rate ranged from 9 to 54%, and reoperation rate ranged from 0 to 55%. Graft-host non-union (type 2) was the most common mode of failure, with rates ranging from 0 to 75%. The mean MSTS scores at last follow-up ranged from 57 to 90% across studies. A trend towards better functional outcomes was seen in patients having an APC with a reverse total shoulder arthroplasty (rTSA) compared with those with hemiarthroplasty (HA). CONCLUSIONS APCs show promise in proximal shoulder reconstruction, with heterogenous functional outcomes that are non-inferior to other reconstruction techniques. Graft host non-union is a common mode of failure and remains a concern in this type of prosthesis. Future studies should compare rTSA-APCs and rTSA endoprostheses while controlling for potential confounders.

Abstract
BACKGROUND Cutibacterium acnes (C acnes) is a commensal skin bacterium, primarily found in sebaceous glands and hair follicles, with a high prevalence in the shoulder region. It is the most common pathogenic organism in prosthetic joint infections after shoulder arthroplasty. Because of its low virulence, its diagnosis remains difficult. PURPOSE To evaluate the relative effects of topical preparations in reducing C acnes in shoulder surgery. STUDY DESIGN Meta-analysis; Level of evidence, 1. METHODS We searched the MEDLINE, Embase, PsychINFO, and Cochrane Library databases in March 2022. Randomized controlled trials (RCTs) comparing any form of topical preparation in arthroscopic or open shoulder surgery were included. The primary outcome was a reduction in the number of positive C acnes cultures. Secondary outcomes were adverse events related to the application of topical preparations. We performed a network meta-analysis to facilitate simultaneous comparisons between multiple preparations across studies. We calculated differences between preparations using odds ratios and their 95% CIs. The risk of bias was assessed using the Cochrane risk-of-bias tool. RESULTS The search yielded 17 RCTs (1350 patients), of which 9 were suitable for the network meta-analysis (775 patients). Overall, 2 RCTs were deemed as having a low risk of bias, and 15 raised "some concerns" of bias. Preparations included benzoyl peroxide (BPO), BPO combined with clindamycin, chlorhexidine gluconate, hydrogen peroxide, povidone-iodine, and water with soap. Only BPO resulted in significantly lower odds of a positive C acnes culture compared with placebo or soap and water (odds ratio, 0.12 [95% CI, 0.04-0.36]). There was no statistically significant difference with all other topical preparations. The only adverse events were skin irritation from BPO and chlorhexidine gluconate in a small number of reported cases. CONCLUSION BPO was the most effective topical agent in reducing the prevalence of C acnes in shoulder surgery. These results were limited by a combination of indirect and direct data. Future studies should focus on establishing the optimal frequency and duration of preoperative BPO to further reduce the burden of C acnes. REGISTRATION CRD42022310312 (PROSPERO).

Abstract
BACKGROUND Perioperative intravenous (IV) dexamethasone is commonly used in lower extremity total joint arthroplasty to manage postoperative pain and nausea/vomiting, and recent studies have demonstrated that its use may lower rates of acute postoperative medical complications. However, there is limited information regarding the safety and efficacy of IV dexamethasone in patients undergoing total shoulder arthroplasty (TSA). Additionally, there is concern surrounding corticosteroid use prior to surgery as preoperative corticosteroid injections have been associated with adverse outcomes after TSA, including periprosthetic joint infection (PJI) and revision surgery. Thus, the purpose of this study was to evaluate the effect of perioperative IV dexamethasone on 90-day rates of PJI, wound complications, and medical complications after TSA. METHODS The Premiere national hospital database was used to identify adult patients undergoing elective TSA between 2016 and 2020; patients were excluded if they were under 18 years old, were undergoing revision TSA, or had a prior proximal humerus open reduction internal fixation (ORIF) procedure. Patients who did and did not receive perioperative IV dexamethasone were then compared in both univariate and multivariate analyses. A Bonferroni correction was utilized to adjust for multiple comparisons. The primary endpoint was risk of acute infectious complications within 90 days of surgery, including PJI and wound infection/dehiscence. Secondary endpoints included acute pulmonary, renal, and thromboembolic complications. RESULTS A total of 135,333 patients underwent TSA during the study period; 61.2% underwent reverse total shoulder arthroplasty (RTSA), 33.8% underwent anatomic total shoulder arthroplasty (ATSA), and 5.0% underwent hemiarthroplasty (HA). From 2016 to 2020, perioperative IV dexamethasone use increased by 135%. Multivariate analysis revealed that patients who received perioperative IV dexamethasone did not have increased odds of PJI, superficial wound infection, or wound dehiscence (p = 0.15 - 0.47) but did have decreased odds of sepsis (OR 0.67, 95% CI 0.55-0.81) and other medical complications such as urinary tract infection (UTI) and acute kidney injury (AKI). Additionally, there was a trend towards decreased 90-day hospital readmission (OR 0.88, 95% CI 0.81-0.96, p=0.003). CONCLUSIONS Perioperative IV dexamethasone was not associated with increased risk of acute infectious and wound healing complications. Moreover, patients who received perioperative IV dexamethasone had decreased odds of medical complications and trended towards lower rates of 90-day hospital readmission. The results of this study support the safety of perioperative IV dexamethasone use in patients undergoing elective TSA.

Abstract
Background: Reversed total shoulder arthroplasty (RTSA) is an established surgery for many pathologies of the shoulder and the demand continues to rise with an aging population. Preoperative planning is mandatory to support the surgeon's understanding of the patient's individual anatomy and, therefore, is crucial for the patient's outcome. Methods: In this observational study, we identified 30 patients who underwent RTSA with two- and three-dimensional preoperative planning. Each patient underwent new two-dimensional planning from a medical student and an orthopedic resident as well as through a mid-volume and high-volume shoulder surgeon, which was repeated after a minimum of 4 weeks. The intra- and interobserver reliability was then analyzed and compared to the 3D planning and the implanted prosthesis. The evaluated parameters were the size of the pegged glenoid baseplate, glenosphere, and humeral short stem. Results: The inter-rater reliability showed higher deviations in all four raters compared to the 3D planning of the base plate, glenosphere, and shaft. The intra-rater reliability showed a better correlation in more experienced raters, especially in the planning of the shaft. Conclusions: Our study shows that 3D planning is more accurate than traditional planning on plain X-rays, despite experienced shoulder surgeons showing better results in 2D planning than inexperienced ones.

Abstract
Porous metallic prosthesis components can now be manufactured using additive manufacturing techniques, and may prove beneficial for promoting bony ingrowth, for accommodating drug delivery systems, and for reducing stress shielding. Using finite element modeling techniques, 36 scenarios (three porous stems, three bone densities, and four held arm positions) were analysed to assess the viability of porous humeral stems for use in total shoulder arthroplasty, and their resulting mechanobiological impact on the surrounding humerus bone. All three porous stems were predicted to experience stresses below the yield strength of Ti6Al4V (880 MPa) and to be capable of withstanding more than 10 million cycles of each loading scenario before failure. There was an indication that within an 80 mm region of the proximal humerus, there would be a reduction in bone resorption as stem porosity increased. Overall, this study shows promise that these porous structures are mechanically viable for incorporation into permanent shoulder prostheses to combat orthopedic infections.

Abstract
INTRODUCTION Superior augment use may help avoid superior tilt while minimizing removal of inferior glenoid bone. Therefore, our goal is to compare superior augments versus no augment baseplates in RSA for patients with rotator cuff dysfunction and no significant superior glenoid erosion. METHODS A multicenter retrospective analysis of 145 patients who underwent RSA with intraoperative navigation (Exactech, Equinoxe GPS) and three-year follow-up (mean 32-month follow-up, range 20 to 61 months) who had preoperative superior inclination less than 10 degrees and retroversion less than 15 degrees. Patient demographics, radiographic measurements, surgical characteristics, patient-reported outcomes at preoperative and postoperative visit closest to three years, and adverse events at final follow-up were obtained. Operative time, planned inclination, and planned version of the baseplate were obtained. Chi-square test used to compare categorical variables and student t-test used to compare augment and no augment cohorts. RESULTS The study population consisted of 54 superior augment patients and 91 no augment patients. The augment cohort had lower BMI (27.2 vs. 29.4, p-0.023), higher native superior inclination (5.9 vs. 1.4 degrees, p<0.001). No difference between the augment and no augment cohorts was found regarding age (p=0.643), gender (p=0.314), medical comorbidities (p>0.05), surgical indication (p=0.082), and native glenoid version (p=0.564). The augment cohort had higher internal rotation score (4.6 vs. 3.9, p=0.023), all remaining ROM and PROs preoperatively were not significantly different. At final follow-up, active ROM in all planes was not different between the cohorts. Regarding PROs, the postoperative SAS score was significantly higher (78.0 vs. 73.6, p=0.042), and ASES score trended towards higher (83.6 vs. 77.5, p=0.063) in the augment cohort. The augment cohort had significantly lower proportion of patients planned to have superior baseplate tilt (1.9% vs. 14.3%, p=0.012), and had greater mean inclination correction (6.3 vs. 1.3 degrees, p<0.001), compared to no augment cohort. Adverse events were rare, and there was no significant difference found between the augment and no augment cohorts (5.6% vs. 3.3%, p=0.509). DISCUSSION Superior augmented baseplate in RSA with minimal superior glenoid erosion is associated with similar ROM and adverse events with somewhat improved postoperative PROs compared to non-augmented baseplates at 3-year follow-up. Additionally, superior augments resulted in a greater proportion of baseplates planned to avoid superior tilt, and trended toward shorter operative times. Further investigation of long-term glenoid baseplate loosening is imperative to fully understand the cost-effectiveness of superior augments in the setting of minimal glenoid deformity.

Abstract
BACKGROUND Severe glenoid bone loss in the setting of both primary and revision reverse total shoulder arthroplasty (rTSA) continues to remain a significant challenge. The purpose of this study was to report on radiographic and clinical outcomes of primary and revision rTSA using a patient-matched, 3-dimensionally printed metal glenoid implant to address severe glenoid bone deficiency. This is a follow-up study to previously reported preliminary results. METHODS A retrospective review was performed on 62 patients with severe glenoid bone deficiency underwent either primary or revision rTSA using the Comprehensive Vault Reconstruction System (VRS) (Zimmer Biomet, Warsaw, IN, USA) at a single institution. Preoperative and postoperative values for the Disabilities of the Arm, Shoulder and Hand (DASH), Constant, American Shoulder and Elbow Surgeons (ASES), Simple Shoulder Test (SST), Single Assessment Numeric Evaluation (SANE), and Visual Analog Scale (VAS) pain scores as well as active range of motion (ROM) were collected and compared using the Wilcoxon signed rank test with the level of statistical significance set at P < 0.05. Percentage of patients achieving minimal clinical important difference (MCID) and substantial clinical benefit (SCB) was also calculated. RESULTS Fifty-five of 62 (88.7%) shoulders were able to be contacted at a minimum of 2-years postoperatively, with 47/62 (75.8%), having complete clinical and radiographic follow-up with a mean age of 67.5 years (range, 48-85 years) and follow-up of 39.2 months (range, 25-56 months). There were 19 primary and 28 revision rTSAs. Significant improvements were seen in mean active forward flexion (63.1° ± 30.3° to 116.8° ± 35°), abduction (48.1° ± 16.1 to 76.2° ± 13.4°) (P < 0.001), external rotation (16° ± 23.7° to 32.1° ± 24.5°) (P < 0.005), DASH (59.9 ± 17.7 to 35.7 ± 24.3), Constant (23.4 ± 13.1 to 53.1 ± 17.4), ASES (27.8 ± 16.2 to 69.1 ± 25.2), SST (3.3 ± 2.5 to 7.6 ± 3.5), SANE (28.9 ± 18.3 to 66.7 ± 21.2), and VAS pain (7.1 ± 2.4 to 1.8 ± 2.6) scores (P < 0.001). MCID and SCB was achieved in a majority of patients postoperatively. Overall complication rate was 29.1% with only 1 baseplate failure. CONCLUSION This study demonstrates promising evidence that the VRS implant can be used as a viable option to achieve clinically important improvement in a majority of patients treated for severe glenoid bone deficiency with rTSA in both the primary and revision setting.

Abstract
Background Machine learning algorithms are finding increasing use in prediction of surgical outcomes in orthopedics. Random forest is one of such algorithms popular for its relative ease of application and high predictability. In the process of sample classification, algorithms also generate a list of variables most crucial in the sorting process. Total shoulder arthroplasty (TSA) is a common orthopedic procedure after which most patients are discharged home. The authors hypothesized that random forest algorithm would be able to determine most important variables in prediction of nonhome discharge. Methods Authors filtered the National Surgical Quality iImprovement Program database for patients undergoing elective TSA (Current Procedural Terminology 23472) between 2008 and 2018. Applied exclusion criteria included avascular necrosis, trauma, rheumatoid arthritis, and other inflammatory arthropathies to only include surgeries performed for primary osteoarthritis. Using Python and the scikit-learn package, various machine learning algorithms including random forest were trained based on the sample patients to predict patients who had nonhome discharge (to facility, nursing home, etc.). List of applied variables were then organized in order of feature importance. The algorithms were evaluated based on area under the curve of the receiver operating characteristic, accuracy, recall, and the F-1 score. Results Application of inclusion and exclusion criteria yielded 18,883 patients undergoing elective TSA, of whom 1813 patients had nonhome discharge. Random forest outperformed other machine learning algorithms and logistic regression based on American Society of Anesthesiologists (ASA) classification. Random forest ranked age, sex, ASA classification, and functional status as the most important variables with feature importance of 0.340, 0.130, 0.126, and 0.120, respectively. Average age of patients going to facility was 76 years, while average age of patients going home was 68 years. 78.1% of patients going to facility were women, while 52.7% of patients going home were. Among patients with nonhome discharge, 80.3% had ASA scores of 3 or 4, while patients going home had 54% of patients with ASA scores 3 or 4. 10.5% of patients going to facility were considered of partially/totally dependent functional status, whereas 1.3% of patients going home were considered partially or totally dependent (P value < .05 for all). Conclusion Of various algorithms, random forest best predicted discharge destination following TSA. When using random forest to predict nonhome discharge after TSA, age, gender, ASA scores, and functional status were the most important variables. Two patient groups (home discharge, nonhome discharge) were significantly different when it came to age, gender distribution, ASA scores, and functional status.

Abstract
BACKGROUND There is still no consensus among surgeons on whether to perform a 1- or 2-stage surgical revision in infected shoulder arthroplasties. The aim of this systematic review and meta-analysis is to rigorously synthesize published studies evaluating the clinical outcomes, recurrence of infection, and other clinical complications in order to discuss which is the best strategy for treating periprosthetic joint infection after shoulder arthroplasty. METHODS Upon research using the PubMed, Scopus, and Web of Science databases, in November 2022, studies that presented 1- or 2-stage surgical revision as a treatment for periprosthetic joint infection after shoulder arthroplasty and assessed the reinfection rate on these patients, as well as other clinical outcomes, with a minimum follow-up of 12 months, were included. Study quality was evaluated using the Methodological Index for Non-Randomized Studies (MINORS) score. Reinfection and complication rates were extracted, and pooled estimates were calculated using the random-effect model. RESULTS After careful screening, 44 studies were included, 5 reporting on 1-stage and 30 on 2-stage revisions and 9 assessing both strategies. A total of 185 shoulders were reported in 1-stage revision studies, whereas 526 shoulders were reported in 2-stage revision studies. The overall pooled random-effects reinfection rate was 6.68% (95% confidence interval [CI]: 3.76-10.13), with low heterogeneity (I2 = 28%, P = .03). One-stage revision showed a reinfection rate of 1.14% (95% CI: 0.00-4.88), whereas 2-stage revision analysis revealed a reinfection rate of 8.81% (95% CI: 4.96-13.33). There were significant statistical differences between 1- and 2-stage reinfection rates (P = .04). The overall pooled rate for other clinical complications was 16.76% (95% CI: 9.49-25.15), with high heterogeneity (I2 = 70%, P < .01). One-stage revision had a complication rate of 6.11% (95% CI: 1.58-12.39), whereas the 2-stage revision complication rate was 21.26% (95% CI: 11.51-32.54). This difference was statistically significant (P = .03). CONCLUSIONS This is the first systematic review and meta-analysis showing significant statistical differences between 1- and 2-stage surgical revision in infected shoulder arthroplasties. Provided the right conditions exist, 1-stage revision shows better results in infection control, with lower clinical complications and possible better clinical outcomes.

Abstract
BACKGROUND The purpose of this study is to assess the trends in operative management of geriatric (≥65 years) proximal humerus fractures during a 6-year period (2015-2020) within an insurance claims database. METHODS This retrospective database cohort study used data gathered from the 2015-2020 IBM Truven MarketScan Commercial and IBM Truven MarketScan Medicare Supplemental databases. The International Statistical Classification of Disease and Related Health Problems, Tenth Revision, data was correlated to the Current Procedural Terminology code for shoulder arthroplasty (proximal humeral prosthetic replacement: 23616, shoulder hemiarthroplasty [HA]: 23470, reverse total shoulder arthroplasty [rTSA]: 23472) or open reduction internal fixation (ORIF; open treatment of proximal humerus fracture with internal fixation: 23615, open treatment of proximal humerus fracture-dislocation with internal fixation: 23680). We investigated the number of proximal humerus fracture operative cases per year, percentage arthroplasty used per year, rTSA and HA per year, hospital cost information, as well as percentage arthroplasty per US geographic region. RESULTS A total of 8057 operative proximal humerus fractures cases were identified in 7697 patients aged >65 years, with 0.45% (360 of 8057) being bilateral. There was a 40.8% decrease in the rate of operative management of proximal humerus fractures between the first half (2015-2017, 1687.3 ± 146.6) and the second half of the study period (2018-2020, 998.3 ± 258.7). Arthroplasty accounted for 78.7% of all surgeries, 91% of those being rTSA. The total number of cases of rTSA and ORIF performed decreased per year (P = .01). The downward trend of percentage ORIF per year approached significance (P = .054). Arthroplasty was a more expensive option of payment for total case by almost $850.00 (P = .001). There was a larger percentage of arthroplasty performed in the Northeast and North Central US geographic regions. CONCLUSION Despite the rise of both the elderly population and related geriatric proximal humerus fractures, they were less operatively represented in this insurance claims database across the 6-year period. There may be a trend to use less ORIF when addressing these fractures. Although it incurred a higher in-hospital cost, arthroplasty was being performed at a higher percentage in the Northeast and North Central regions of the United States.

Abstract
Artificial intelligence (AI) is amongst the most rapidly growing technologies in orthopedic surgery. With the exponential growth in healthcare data, computing power, and complex predictive algorithms, this technology is poised to aid providers in data processing and clinical decision support throughout the continuum of orthopedic care. Understanding the utility and limitations of this technology is vital to practicing orthopedic surgeons, as these applications will become more common place in everyday practice. AI has already demonstrated its utility in shoulder and elbow surgery for imaging-based diagnosis, predictive modelling of clinical outcomes, implant identification, and automated image segmentation. The future integration of AI and robotic surgery represents the largest potential application of AI in shoulder and elbow surgery with the potential for significant clinical and financial impact. This editorial's purpose is to summarize common AI terms, provide a framework to understand and interpret AI model results, and discuss current applications and future directions within shoulder and elbow surgery.

Abstract
BACKGROUND Descriptions of glenoid deformities in glenohumeral osteoarthritis (GHOA) have focused on the axial plane. Less is known regarding arthritic glenoids with higher amounts of superior inclination and little evidence exists to guide management of inclination or combined version-inclination deformity when performing anatomic total shoulder arthroplasty (aTSA). We hypothesized that biplanar deformities (BD) would be present in a higher proportion of GHOA patients than previously appreciated, and these deformities would be difficult to adequately reconstruct with contemporary aTSA implants. METHODS A retrospective query was performed of GHOA patients indicated for TSA 2012-2017 with a computed tomography (CT) scan within three months of surgery. Images were uploaded to three-dimensional software for automated measurements. Glenoids with superior inclination ≥10˚, retroversion ≥20˚ were considered to have BD. Walch classification was determined, C-type glenoids were excluded. Rotator-cuff muscle cross-sectional area (CSA) was measured and fatty infiltration graded. Glenoids with BD were virtually planned for aTSA with correction to neutral inclination and version, then 5˚ superior inclination and 10˚ retroversion. RESULTS Two-hundred sixty-eight shoulders in 250 patients were included; average age 65 years, 67% male. There were no differences in inclination between Walch types (p=0.25). Twenty-nine shoulders with BD were identified (11%). These deformities were not associated with age (p=0.47) or gender (p=0.50) but were skewed towards Walch B-type, specifically B2 (p=0.03). Acromial index and posterior humeral head subluxation were higher in BD patients (p=0.04, p<0.001, respectively). Biplanar deformities had similar cuff CSA compared to those without but were less frequently associated with fatty infiltration of the subscapularis (p=0.05). When correcting to neutral version and inclination, 41% BD could not be reconstructed. Of those that could, 94% required augmented implants. When correcting to 5˚ superior inclination and 10˚ retroversion, 10% could not be reconstructed. Of those that could, 58% required augmented implants. With partial correction, augment use was predicted by retroversion >26˚ (p=0.009). Inclination did not predict augment use (p=0.90). Final implant position commonly involved unseating in the posterosuperior quadrant and cancellous exposure in the anteroinferior quadrant. CONCLUSIONS This retrospective CT-based study of 268 shoulders with GHOA found a 11% prevalence of BD. These deformities were commonly associated with Walch B2 wear patterns. Virtual aTSA planning showed a high failure rate (41%) when correcting to neutral version and inclination. Posteriorly augmented implants were frequently required, and often still involved unseating in the posterosuperior quadrant, increased cancellous exposure in the anteroinferior quadrant, and vault perforation.

Abstract
BACKGROUND Increased body mass index (BMI) is a potential risk factor for poorer outcomes and complications. However, the influence of BMI on the long-term outcomes of anatomic and reverse total shoulder arthroplasty (aTSA and rTSA) remains to be fully elucidated. METHODS Institutional records were queried to identify patients who underwent primary TSA between 2009-2020 with a minimum of 2 years of clinical follow-up. Retrospective review was performed to collect demographics, comorbidity status, and range of motion and strength measurements in forward elevation, external rotation, and internal rotation. Patients were called to obtain patient reported outcomes. Patients were stratified into 3 cohorts, by BMI: underweight or normal weight (U/NW, BMI≤25), overweight (OW, 2530). RESULTS Among 466 TSA patients, 245 underwent aTSA while 221 underwent rTSA. In the aTSA cohort, 40 were classified as U/NW, 72 as OW, and 133 as obese. Comparatively, the rTSA cohort was composed of 33 U/NW, 79 OW, and 209 obese patients. aTSA and rTSA patients had an average follow-up of 5.8±3.2 years and 4.5±2.3 years, respectively. No differences were found in age at surgery for the aTSA group (U/NW: 65.2±7.9 vs obese: 61.9±8.9 years; p=0.133), however, in the rTSA cohort, BMI was found to be inversely related to age at surgery (U/NW: 72.4±8.8 vs obese: 65.7±8.3 years; p<0.001). Across all BMI cohorts, patients saw great improvement in range of motion and strength. Postoperative patient reported outcomes for TSA did not vary by BMI in SANE, SST, VAS pain, and ASES scores. There was no significant difference in survival rates at 10-year follow-up in aTSA (U/NW: 95.8% vs obese: 93.2%; p=0.753) or rTSA (U/NW: 94.7% vs obese: 94.5%; p=0.791). CONCLUSION With dramatic improvements in range of motion, minimal differences in patient reported outcomes, and high rates of implant survival, TSA is a safe and effective treatment option for all patients, including for overweight and obese patients.

Abstract
BACKGROUND Prosthetic joint infections (PJI) of the shoulder are a devastating complication of shoulder arthroplasty and are commonly caused by Staphylococcus and Cutibacterium acnes. Absorbable calcium sulfate beads are sometimes used for delivering antibiotics in PJI. This study evaluates the in vitro effect of different combinations of gentamicin, vancomycin, and ertapenem in beads made from calcium sulfate cement on the growth of C. acnes and coagulase-negative Staphylococcus strains. METHODS Three strains of C. acnes and five strains of coagulase-negative Staphylococcus from clinically proven shoulder PJI were cultured and plated with calcium sulfate beads containing combinations of vancomycin, gentamicin, and ertapenem. Plates with C. acnes were incubated anaerobically while plates with Staphylococcus were incubated aerobically at 37°C. Zones of inhibition were measured at intervals of 3 and 7 days using a modified Kirby Bauer technique, and beads were moved to plates containing freshly streaked bacteria every 7th day. This process was run in triplicate over the course of 56 days. Statistical analysis was conducted using SPSS v. 28 with repeated measures ANOVA and pairwise comparisons with Tukey correction. RESULTS In experiments with C. acnes, beads containing ertapenem + vancomycin and vancomycin alone formed the largest zones of inhibition over time (p<.001). In experiments with Staphylococcus, beads containing vancomycin alone formed the largest zones of inhibition over time for all five strains (p<.001). Zones of inhibition were 1.4x larger for C. acnes than for Staphylococcus with beads containing vancomycin alone. For both C. acnes and Staphylococcus, beads containing ertapenem had the strongest initial effect, preventing all bacterial growth in C. acnes and almost all growth for Staphylococcus during the first week but dropping substantially by the second week. Beads containing gentamicin alone consistently created smaller zones of inhibition than beads containing vancomycin alone, with vancomycin producing zones 5.3x larger than gentamicin in C. acnes and 1.3x larger in Staphylococcus (p<.001). DISCUSSION These data suggest that for both C. acnes and Staphylococcal species, calcium sulfate beads impregnated with vancomycin were most effective at producing a robust antibiotic effect. Additionally, ertapenem may be a viable supplement in order to create a more potent initial antibiotic effect but is not as effective as vancomycin when used alone. Gentamicin alone was not effective in maintaining consistent and long-term antibiotic effects. These results indicate that amongst the antibiotics currently commercially available to be used with calcium sulfate, vancomycin is consistently superior to gentamicin in the setting of C. acnes and coagulase negative Staphylococci.

Abstract
The shoulder joint has a complex anatomy and biomechanics. It is a ball and socket joint made by the articulation surface of the humeral head (ball) and glenoidal fossa (socket) of the scapula. Shoulder arthroplasty is done when parts of the shoulder joint are severely affected and damaged beyond repair. The damaged parts are replaced with artificial parts. Prosthetic implants are typically made of metal or plastic material. Implants come in various sizes and shapes. There are three types of surgical arthroplasty: total shoulder arthroplasty, partial shoulder arthroplasty, and reverse arthroplasty. Indications of shoulder arthroplasty may include osteoarthritis, fractures, rotator cuff injuries, osteonecrosis, and rheumatoid arthritis. This case study aims to provide a case of anteroinferior dislocation of the left shoulder with humeral head comminuted fracture confirmed by an investigation like radiograph and CT scan operatively managed by left shoulder hemiarthroplasty. In this case study, a 58-year-old male cannot lift his arm and perform actions of the shoulder joint independently after the operative procedure, thus reducing the functional status and quality of life. After the left shoulder hemiarthroplasty repair post due to inadequate rehabilitation, there was a failure in achieving the ranges and gaining back the strength of the muscles. The patient has a combined plan of action, which consists of pharmacological interventions along with physiotherapy rehabilitation. The physiotherapy protocol consists of goals like using electrical muscle stimulation, activation exercises of muscles, strengthening protocol, stretches, and counselling. By the end of the physiotherapy treatment, the patient showed significant progress in re-establishing the ranges and enhanced muscle strength, which resulted in a positive self-boost along with improved functional independence quotient, thereby increasing quality of life.

Abstract
BACKGROUND Postoperative scapular stress fractures (SSFs) are a formidable problem after reverse shoulder arthroplasty (RSA). Less is known about patients who have these fractures preoperatively. The primary aim of this study was to examine postoperative satisfaction in patients undergoing primary RSA who have preoperative SSF and compared to a matched cohort without preoperative fracture. The secondary aim was to examine the differences in patient-reported outcomes between and within study cohorts. METHODS A retrospective chart review of primary RSAs performed by a single surgeon from 2000 to 2020 was conducted. Patients diagnosed with cuff tear arthropathy (CTA), massive cuff tear (MCT), or rheumatoid arthritis (RA) were included. Five hundred twenty-five shoulders met inclusion criteria. Fractures identified on preoperative computed tomography scans were divided into 3 groups: (1) os acromiale, (2) multifragments (MFs), and (3) Levy types. Seventy-two shoulders had an occurrence of SSF. The remaining 453 shoulders were separated into a nonfractured cohort. American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) and visual analog scale (VAS) scores were compared pre- and postoperatively in the total fracture group and the nonfractured group cohort. The multifragment subgroup was also compared to the pooled Os/Levy subgroup. RESULTS The total incidence of SSF in all shoulders was 13.7%. There was a difference in satisfaction scores at all time points between the nonfracture (7.9 ± 2.8) and total fracture group (5.4 ± 3.6, P < .001, at last visit). There was also a greater ASES total score in the nonfractured group vs the total fracture group at the final visit (69.4 ± 23.4 and 62.1 ± 24.2; P = .02). The MF group had worse ASES functional or VAS functional scores than the Os/Levy group at all time points: at 1 year, ASES function: MF 24.2 ± 14.5 and Os/Levy 30.7 ± 14.2 (P = .045); at 2 years, ASES function: MF 21.4 ± 14.4 and Os/Levy 35.5 ± 10.6 (P < .001); and at last follow-up, VAS function: MF 4.8 ± 2.8 and Os/Levy 6.4 ± 3.2 (P = .023). DISCUSSION Scapular fractures were proportionally most common in patients diagnosed with CTA (16.3%) compared with a 9.2% and 8.6% incidence in patients diagnosed with MCT and RA, respectively. Patients with preoperative SSF still see an improvement in ASES scores after RSA but do have lower satisfaction scores compared with the nonfractured cohort. The multifragment fracture group has lower functional and satisfaction scores at all postoperative time points compared with both the nonfracture and the Os/Levy fracture group.

Abstract
Background We reviewed the shoulder arthroplasty (SA) literature to correlate citations, methodological characteristics and quality of most-cited articles in this field. We hypothesized that a greater number of citations would be found for high-quality clinical studies. Methods We searched the Web of Knowledge database for the 50 most-cited articles about SA and collected author name, publication year, country of origin, journal, article type, level of evidence (LoE), subject of paper, type of arthroplasty and metrics (number of citations and citation rate). Coleman Methodology Score (CMS) was computed for clinical articles. Statistical analysis of variance and correlation coefficients were used to investigate the relationship between different variables. Results Out of the selected 50 studies on SA, 26% were nonclinical. There were 15,393 citations overall (mean 307.8), with a mean 19.5 citations per year (range 48.3-6.7). Thirty or 60% of all articles were LoE IV. All studies were published between 1984 and 2011 in 8 journals. Reverse SA (RSA) was the most common subject (36% of studies). The United States was the country responsible for most contributions (50% of studies). CMS ranged from 81 to 38 (mean 59.6). RSA received the highest number of citations (P < .001), independently from country of origin (P = .137) and LoE (P = .723). CMS correlated with citation rate (r = 0.397; P = .013) and publication year (tau = 0.397; P = .013), but not with LoE (P = .204). Conclusion In SA literature, citation rate positively correlates with methodological quality of a study, independently from publication country and LoE. Among most-cited papers, RSA is the most common standalone subject.

Abstract
Background and Objective Crucial to the success of any total or reverse shoulder arthroplasty (RSA) is the stability of the glenoid component fixation. Instability can lead to early implant failure and unsatisfactory results. Patients often present with varying forms of glenoid bone loss (GBL) in both the primary and revision settings, which can be a challenge for the treating surgeon. Severe cases of GBL can increase the risk of potential complications and diminish implant longevity. The use of the reverse total shoulder replacement has been particularly helpful when addressing significant glenoid bony defects. Various approaches have been proposed to deal with GBL, all of which require an individualized assessment of the specifics of the defect in order to provide maximal fixation and thereby optimize the longevity of the shoulder arthroplasty. This article aims to review the recent literature on GBL in shoulder arthroplasty to provide guidance when considering treatment based on the best available evidence. Methods PubMed, MEDLINE, EMBASE, AccessMedicine, ClinicalKey, DynaMed, and Micromedex were queried for publications utilizing the following keywords: "glenoid bone loss" AND "glenoid bone deficiency" AND "shoulder arthroplasty" AND "classification". The search was restricted to research published between 2004 and 2023. There were no restrictions on study type or language. Key Content and Findings GBL should be critically evaluated prior to undertaking total shoulder arthroplasty (TSA). The treating surgeon should be aware of various methods of addressing bone defects. Conclusions The use of TSA is increasing to address various shoulder pathologies. Addressing glenoid bone defects is of critical importance to maximize the longevity and outcome of TSA.

Abstract
INTRODUCTION Maintaining premorbid proximal humeral positioning is an essential consideration of anatomic total shoulder arthroplasty (aTSA), as malposition of the prosthetic humeral head can result in poor clinical outcomes. Stemless aTSA prosthetic heads are usually concentric, while stemmed aTSA prosthetic heads are typically eccentric in nature. Therefore, the purpose of this study was to compare the ability to restore native humeral head position between stemmed (eccentric) vs. stemless (concentric) aTSA. MATERIALS AND METHODS Postoperative anteroposterior radiographs of 52 stemmed and 46 stemless aTSAs were analyzed. A best-fit circle was created using previously published and validated techniques to represent the premorbid humeral head position and axis of rotation. This circle was juxtaposed with another circle following the arc of the implant head. Next, the offset in center of rotation (COR), radius of curvature (RoC), and humeral head height above the greater tuberosity (HHH) were measured. Additionally, based on prior studies, an offset of >3 mm at any point between the implant head surface and premorbid best-fit circle was considered significant and further classified as overstuffed or understuffed. RESULTS RoC deviation was significantly greater in the stemmed cohort than the stemless cohort (1.19 ± 1.37 mm vs. 0.65 ± 1.17 mm, P = .025). There was no statistically significant difference in deviation from premorbid humeral head between the stemmed and stemless cohorts for COR (3.20 ± 2.28 mm vs. 3.23 ± 2.09 mm, P = .800) or HHH (1.12 ± 3.27 mm vs. 0.92 ± 2.70 mm, P = .677). When comparing overstuffed implants to appropriately placed implants, there was a significant difference in overall COR deviation in stemmed implants (3.93 ± 2.51 mm vs. 1.92 ± 1.05 mm, P < .001). Superoinferior COR deviation (stemmed: 2.38 ± 3.01 mm vs. -0.61 ± 1.59 mm, P < .001; stemless: 2.70 ± 1.75 mm vs. -0.16 ± 1.87 mm, P < .001), mediolateral COR deviation (stemmed: 0.79 ± 2.65 mm vs. -0.62 ± 1.27 mm, P = .020; stemless: 0.40 ± 1.41 mm vs. -1.13 ± 1.96 mm, P = .020), and HHH (stemmed: 3.61 ± 2.73 mm vs. 0.50 ± 1.31 mm, P < .001; stemless: 3.98 ± 1.18 mm vs. 0.53 ± 1.41 mm, P < .001) were significantly different between overstuffed implants and appropriate implants in both the stemmed and stemless cohorts. DISCUSSION Stemless and stemmed aTSA implants have similar rates of reproducing satisfactory postoperative humeral head COR with both producing COR deviation most commonly in the superomedial direction. Deviation in HHH contributes to overstuffing in both stemmed and stemless implants, COR deviation contributes to overstuffing in stemmed implants, while RoC (humeral head size) is not associated with overstuffing. Based on this study, it appears that neither eccentric nor concentric prosthetic heads are superior in recreating premorbid humeral head position.

Abstract
BACKGROUND The Walch classification is commonly used by surgeons when determining the treatment of osteoarthritis (OA). However, its utility in prognosticating patient clinical state before and after TSA remains unproven. We assessed the prognostic value of the modified Walch glenoid classification on preoperative clinical state and postoperative clinical and radiographic outcomes in total shoulder arthroplasty (TSA). METHODS A prospectively collected, multicenter database for a single-platform TSA system was queried for patients with rotator cuff-intact OA and minimum 2 year follow-up after anatomic (aTSA) and reverse TSA (rTSA). Differences in patient-reported outcome scores (Simple Shoulder Test, American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form, Shoulder Pain and Disability Index, visual analog scale for pain, Shoulder Function score), combined patient-reported and clinical-input scores (Constant, University of California-Los Angeles shoulder score, Shoulder Arthroplasty Smart Score), active range of motion values (forward elevation [FE], abduction, external rotation [ER], internal rotation [IR], and radiographic outcomes (humeral and glenoid radiolucency line rates, scapula notching rate) were stratified and compared by glenoid deformity type per the Walch classification for aTSA and rTSA cohorts. Comparisons were performed to assess the ability of the Walch classification to predict the preoperative, postoperative, and improved state after TSA. RESULTS 1008 TSAs were analyzed including 576 aTSA and 432 rTSA. Comparison of outcomes between Walch glenoid types resulted in 15 pairwise comparisons of 12 clinical outcome metrics, yielding 180 total Walch glenoid pairwise comparisons for each clinical state (preoperative, postoperative, improvement). Of the 180 possible pairwise Walch glenoid type and metric comparisons studied for aTSA and rTSA cohorts, <6% and <2% significantly differed in aTSA and rTSA cohorts, respectively. Significant differences based on Walch type were seen after adjustment for multiple pairwise comparisons in the aTSA cohort for FE and ER preoperatively, the Constant score postoperatively, and for abduction, FE, ER, Constant score, and SAS score for pre- to postoperative improvement. In the rTSA cohort, significant differences were only seen in abduction and Constant score both postoperatively and for pre- to postoperative improvement. There were no statistically significant differences in humeral lucency rate, glenoid lucency rate (aTSA), scapular notching rate (rTSA), complication rates, or revision rates between Walch glenoid types after TSA. CONCLUSION Although useful for describing degenerative changes to the glenohumeral joint, we demonstrate a weak association between preoperative glenoid morphology according to the Walch classification and clinical state when evaluating patients undergoing TSA for rotator cuff-intact OA. Alternative glenoid classification systems or predictive models should be considered to provide more precise prognoses for patients undergoing TSA for rotator cuff-intact OA.

Abstract
BACKGROUND Cutibacterium acnes remains the most commonly detected organism in shoulder arthroplasty. C acnes infection is thought to occur during shoulder arthroplasty through contamination of the surgical field with C acnes from the incised dermis. The purpose of this study was to examine whether using electrocautery for making skin incisions would decrease C acnes culture rates at the incised dermis compared to using scalpels during shoulder arthroplasty. METHODS Patients undergoing primary shoulder arthroplasty were randomized into 2 groups, electrocautery vs. scalpel incision group. All patients received a standard preoperative antiseptic preparation including chlorhexidine gluconate showers, intravenous antibiotic administration, and topical application of hydrogen peroxide, povidone iodine, isopropyl alcohol, and DuraPrep. Cultures were obtained from the incised dermal edge immediately after skin incision and later from surgeon's gloves and forceps immediately prior to humeral component implantation. The primary outcome was positive C acnes culture rates compared between the groups. RESULTS A total of 64 patients (32 in each group) were enrolled. There were 24 males in each group. Regarding dermis cultures, 10 patients (31%) in the scalpel group were positive with 8 of them positive for C acnes, whereas no patients in the electrocautery group were positive (P < .001). Regarding glove cultures, the electrocautery group had 8 patients positive C acnes, while the scalpel group had 8 (P = .777). Regarding forceps cultures, the electrocautery group had 4 patients positive for C acnes, and the scalpel group had 6 (P = .491). All positive cultures were exclusively from male patients. There were no wound complications or infection in the electrocautery group while the scalpel group had 1 acute postoperative infection. CONCLUSIONS Making skin incisions using electrocautery resulted in 0 C acnes culture at the incised dermis, suggesting its potential effect against C acnes. However, despite this initial antibacterial effect, C acnes still appeared on surgeon's gloves and forceps during surgery of male patients. All positive cultures were from male patients, suggesting that the source of C acnes was specifically related to the male body. While the study hypothesis was supported by the results, the present study also raises new questions and calls for further research.

Abstract
BACKGROUND Home health services provide patients with additional professional care and supervision following discharge from the hospital to theoretically reduce the risk of complication and reduce healthcare utilization. The aim of this investigation was to determine if patients assigned home health services following total shoulder arthroplasty (anatomic (TSA) and reverse (RSA)) exhibited lower rates of medical complications, lower healthcare utilization, and lower cost of care compared to patients not receiving these services. METHODS A national insurance database was retrospectively reviewed to identify all patients undergoing primary anatomic and reverse total shoulder arthroplasty from 2010 to 2019. Patients who received home health services were matched using a propensity score algorithm to a set of similar patients who were discharged home without services. We compared medical complication rates, emergency department (ED) visits, readmissions, and 90-day cost of care between the groups. Multivariate regression analysis was performed to determine the independent effect of home health services on all outcomes. RESULTS 1,119 patients received home health services and were matched to 11,190 patients who were discharged home without services. There was no significant difference in patients who received home health services compared to those who did not receive home health services with respect to rates of ED visits within 30 days (OR 1.293; p = 0.0328) and 90 days (OR 1.215; P = 0.0378), while the home health group demonstrated increased readmissions within 90 days (OR 1.663; P<0.001). For all medical complications, there was no difference between cohorts. Episode-of-care costs for home health patients were higher than those discharged without these services ($12,521.04 vs $9,303.48; P < .001). CONCLUSION Patients assigned home health care services exhibited higher cost of care and readmission rates without a reduction in the rate of complication or early return to the ED. These findings suggest that home healthcare services should be strongly analyzed on a case-by-case basis to determine if a patient may benefit from its implementation.

Abstract
Objective We aimed to evaluate the difference in 30-day outcomes after surgical management of proximal humerus fractures (PHFs) between patients with and without chronic liver disease as defined by a MELD score greater than 10. Design This was a retrospective database review. Setting All centers participating in the American College of Surgeons National Surgical Quality Improvement Program database were included. Patients/Participants Patients with proximal humerus fractures who (1) underwent ORIF, HA, or SA and (2) had calculable MELD scores were included. Intervention Open reduction and internal fixation, hemiarthroplasty, or shoulder arthroplasty was used for treatment. Main outcome measurements Thirty-day complications, mortality, readmission, and reoperation rates were measured. Results Of the total 1732 PHF patients identified, 300 had a MELD score higher than 10. After propensity matching by significant covariates, MELD score higher than 10 was found to be significantly associated with higher rates of 30-day mortality, 30-day readmission, transfusion within 72 hours, and systemic complications. Among patients with a MELD score higher than 10, treatment with SA or HA instead of ORIF was associated with a higher rate of transfusion and longer operative time. There were no significant differences between treatment cohorts regarding mortality, reoperation, readmission, or complications. Conclusions A MELD score higher than 10 is associated with higher risk of surgical complications, transfusion, and death in patients undergoing surgery for proximal humerus fractures. Among patients with a MELD score higher than 10, ORIF was associated with a lower transfusion rate and shorter operative time than arthroplasty or hemiarthroplasty. Level of Evidence Prognostic Level III.

Abstract
Introduction Few studies have analyzed the effect of preoperative opioid use on postoperative outcomes after total shoulder arthroplasty (TSA). Methods Patients undergoing TSA were identified in the Pearldiver Humana Claims Dataset and stratified by level of preoperative opioid use. Primary outcomes were 90-day complications, readmissions, and revision surgery. Chi-square test and ANOVA were used to evaluate categorical and continuous variables respectively. A multivariable logistic regression analysis and a sub analysis excluding fracture as a primary diagnosis were completed. Results 18,791 patients underwent aTSA and rTSA including 9933 opioid naïve patients, 3016 sporadic opioid users and 5842 persistent opioid users. Significant differences were found in complications (6.0% vs 6.1% vs 9.1%, p < .001), readmission (7.6% vs 8.2% vs 12.6%, p < .001), and revision procedures (1.1% vs 1.1% vs 2.3%, p < .001) which remained significant after excluding fractures. After adjusting for comorbidity burden, persistent opioid use was associated with increased likelihood of complications (OR 1.4, 1.2-1.6), readmission (OR 1.6, 1.5-1.8) and revision procedures (OR 1.9, 1.5-2.4). This association remained after excluding fractures. Conclusion Persistent preoperative opioid use is associated with increased risk of early postoperative complications, readmission, and revision surgery for patients undergoing shoulder arthroplasty.

Abstract
Background The purpose of this study was to investigate the associations between each mental health patient-reported outcome measure with postoperative functional outcomes following shoulder arthroplasty, and to compare psychometric properties of patient-reported outcomes measurement information system depression to the legacy (VR-12 Mental) patient-reported outcome measure. Methods Patients who underwent primary shoulder arthroplasty from July 2018 to February 2019 were retrospectively reviewed. Patient-reported outcomes measurement information system depression and VR-12 Mental were administered preoperatively; American Shoulder and Elbow Surgeons and Single Assessment Numeric Evaluation were administered at 6-month and 1-year postoperatively. Rasch partial credit modeling analysis was used to compare psychometric properties of legacy versus patient-reported outcomes measurement information system instruments in assessing mental health. Results Ninety-three patients who underwent total shoulder arthroplasty (n = 52), reverse total shoulder arthroplasty (n = 39), or hemiarthroplasty (n = 2) were included. Preoperative VR-12 Mental scores were moderately associated with American Shoulder and Elbow Surgeons at 6-months (coefficient: 0.52, P = 0.026) and 1-year (coefficient: 0.65, P = 0.002), while preoperative patient-reported outcomes measurement information system depression scores were not. Patient-reported outcomes measurement information system depression demonstrated significant floor effects (16%); VR-12 Mental demonstrated minimal floor and ceiling effects (1.1% for both). VR-12 Mental demonstrated broader coverage of mental outlook on Rasch modeling than patient-reported outcomes measurement information system depression and had adequate model fit after one round of reiterative item elimination. Discussion Patient-reported outcomes measurement information system depression was poorly associated with postoperative American Shoulder and Elbow Surgeons scores, demonstrated significant floor effects, and had limited coverage of mental health on Rasch modeling with reiterative elimination.

Abstract
BACKGROUND Anemia is a major cause of morbidity worldwide and compounds numerous medical conditions. Studies have found associations between anemia and both medical and surgical complications after shoulder arthroplasty (SA); however, most of these studies have used commercially available national databases with limited information on outcomes and typically short-term follow-up. Our study sought to evaluate the midterm outcomes of primary SA at a single institution when stratified by the degree of preoperative anemia. METHODS Between 2000 and 2020, 5231 primary SA (477 hemiarthroplasties, 2091 anatomic total SA, and 2335 reverse SA) with preoperative hematocrit values available and a minimum follow-up of 2 years were collected from a single-institution joint registry database. The severity of anemia was subclassified as no anemia (hematocrit >39% for males, >36% for females; n = 4194 [80.2%]), mild anemia (hematocrit 33%-39% for males, 33%-36% for females; n = 742 [14.2%]), and moderate-to-severe anemia (hematocrit <33% for both males and females; n = 295 [5.6%]). The mean follow-up time for the entire cohort was 5.9 years (range, 2-22 years). Medical and surgical complications, reoperations, revisions, and implant survivorship were assessed. RESULTS SA with moderate-to-severe anemia had the highest rate of nonfatal and nontransfusion medical complications (5.1%) relative to the nonanemic (1.2%; P < .001) and mild anemic groups (1.5%; P < .001). Similarly, SA with moderate-to-severe anemia had the highest rate of surgical complications (19.3%) compared with mild anemia (14.3%; P = .044) and no anemia (11.6%; P < .001). Postoperative transfusion was most frequent in the moderate-to-severe anemia cohort (40.3%) compared with the mild anemia (14.2%; P < .001) and nonanemic groups (2.5%; P < .001). Furthermore, SA who received postoperative transfusions had a higher risk of nonfatal medical complications (8.2% vs. 1.0%; P < .001), 90-day mortality (1.5% vs. 0.03%; P = .001), and surgical complications (19.5% vs. 12.0%; P < .001) when compared with those without transfusion. CONCLUSIONS Moderate-to-severe anemia (hematocrit <33% for both males and females) was identified in approximately 5.6% of patients who underwent SA at a single institution and was associated with increased medical and surgical complications. Patients who received postoperative transfusions presented elevated rates of medical complications, 90-day mortality, and surgical complications. Health care teams should be aware of these risks in order to provide more individualized medical optimization and postoperative monitoring.

Abstract
Background: Periprosthetic joint infection (PJI) after shoulder arthroplasty remains a significant complication. This study aimed to explore the epidemiology and risk factors of shoulder PJI in patients aged 60 and younger, analyze treatment options, and evaluate outcomes after 1-year follow-up. Methods: In this retrospective multicentric observational study, data from 1404 shoulders in patients under 60 who underwent primary shoulder arthroplasty were analyzed. Patients with PJI and at least 1-year follow-up after infection treatment were included. Results: The study identified 55 shoulders with PJI, resulting in a 2.35% infection rate after primary shoulder arthroplasty in the young population. Male gender and reverse shoulder arthroplasty were risk factors for infection, while previous surgeries did not significantly contribute. The most common causative agents were Cutibacterium acnes and Staphylococcus epidermidis. Open washout had a 52.9% success rate for acute infections, while one-stage and two-stage revisions achieved infection control rates of 91.3% and 85.7%, respectively. Resection arthroplasty had an 81.8% success rate but poorer functional outcomes. Conclusions: PJI following shoulder arthroplasty in young patients is a significant concern. Preoperative planning should be carefully considered to minimize infection risk. Treatment options such as open washout and one-stage and two-stage revisions offer effective infection control and improved functional outcomes. Resection arthroplasty should be reserved for complex cases where reimplantation is not a viable option.

Abstract
BACKGROUND Shoulder arthroplasty (SA), including hemiarthroplasty, reverse and anatomical total SA (TSA), improves quality of life by reducing shoulder pain and restoring function in patients not only with irreparable rotator cuff tears and/or cuff tear arthropathy but also with osteoarthritis posttraumatic arthritis, proximal humeral fractures, etc. Given the rapid developments in artificial joints and improvements in postoperative outcomes, the number of SA surgeries is increasing worldwide. Therefore, we investigated changes in trends over time in Korea. METHODS We analyzed the longitudinal changes in the incidence of SA including anatomic and reverse TSA, hemiarthroplasty, and shoulder revision arthroplasty (SRA) by changes in the Korean age profile, surgical facilities, and geographical regions using the Korean Health Insurance Review and Assessment Service database from 2010 to 2020. Data were also collected from the National Health Insurance Service and the Korean Statistical Information Service. RESULTS From 2010 to 2020, the TSA rate per 1,000,000 person-years increased from 10.571 to 101.372 (time trend = 1.252; 95% CI 1.233-1.271, P < .001). The shoulder hemiarthroplasty (SH) rate per 1,000,000 person-years decreased from 6.414 to 3.685 (time trend = 0.933; 95% CI 0.907-0.960, P < .001). The SRA rate per 1,000,000 person-years increased from 0.792 to 2.315; the increase was significant (time trend = 1.133; 95% CI 1.101-1.166, P < .001). DISCUSSION Overall, TSA and SRA are increasing and SH is decreasing. For both total TSA and SRA, steep increases are evident in the numbers of patients in their 70s and older than 80 years. The SH trend is decreasing regardless of differences in age groups, surgical facilities, and geographical regions. SRA is preferentially performed in Seoul.

Abstract
BACKGROUND The incidence of shoulder arthroplasty has continued to increase over the past decade. In response, commercial payers have implemented strategies to control the medical requirement of these surgeries in attempt to contain the growing costs. For example, most payers require a prolonged trial of conservative management prior to shoulder arthroplasty for patients who may otherwise be surgical candidates. However, little is known regarding the evidence used to support these indications. The purpose of this study was to analyze the references used by commercial payers to substantiate their coverage policies for shoulder arthroplasty. METHODS Ten of the leading commercial payers for total shoulder arthroplasty were identified. Publicly available coverage policies were searched on the internet or requested directly from the payer via email or telephone. Cited references were reviewed independently by two authors for type of document, level of evidence, and mention of the efficacy of conservative management. RESULTS A total of 5 coverage policies were obtained with 118 references. The most common reference type was primary journal article (n = 70; 59.3%) followed by review or expert opinion articles (n = 35; 29.7%). Most references were of level IV evidence (n = 60; 52.2%), with only 6 (5.2%) of level I or II evidence. Only 4 (3.5%) references mentioned the efficacy of conservative management in patients who may be candidates for shoulder arthroplasty. CONCLUSION The majority of references used to substantiate the coverage policies for shoulder arthroplasty among major commercial payers within the United States are of low scientific evidence and fail to demonstrate the success of required nonoperative intervention strategies. Our study underscores the need for high-quality, comparative trials that evaluate the outcomes of conservative management vs. shoulder arthroplasty in end-stage glenohumeral osteoarthritis patients in order to determine the most cost-effective treatment algorithm.

Abstract
BACKGROUND Many factors contribute to the risk of surgical-site infection (SSI) following total shoulder arthroplasty (TSA). Operative time is a modifiable factor that may contribute to SSI occurrence after TSA. This study aimed to determine the correlation between operative time and SSI following TSA. MATERIALS AND METHODS By use of the American College of Surgeons National Surgical Quality Improvement Program database, a total of 33,987 patient records were queried from 2006 to 2020 and sorted by operative time and the development of an SSI in the 30-day postoperative period. Odds ratios for the development of an SSI were calculated based on operative time. RESULTS An SSI developed in the 30-day postoperative period in 169 of the 33,470 patients in this study, resulting in an overall SSI rate of 0.50%. A positive correlation was identified between operative time and the SSI rate. An inflection point was identified at an operative time of 180 minutes, with a significant increase in the rate of SSI occurrence for operative times >180 minutes. DISCUSSION AND CONCLUSION Increased operative time was shown to be strongly correlated with an increased risk of SSI within 30 days following surgery, with a significant inflection point at 180 minutes. The target operative time for TSA should be <180 minutes to reduce the risk of SSI.

Abstract
Purpose The goal of this study was to review available literature on periprosthetic shoulder fractures to evaluate epidemiology, risk factors and support clinical decision-making regarding diagnostics, preoperative planning, and treatment options. Methods Two authors cross-checked the PubMed and Web of Science medical databases. The inclusion criteria were as follows: original human studies published in English, with the timeframe not limited, and the following keywords were used: 'periprosthetic shoulder fracture,' 'total shoulder arthroplasty periprosthetic fractures,' 'total shoulder arthroplasty fracture,' and 'total shoulder replacement periprosthetic fracture.' Seventy articles were included in the review. All articles were retrieved using the aforementioned criteria. Results The fracture rate associated with total shoulder arthroplasty varied between 0 and 47.6%. Risk factors for periprosthetic fractures were female gender, body mass index < 25 kg/m2, smoking, rheumatoid arthritis, and Parkinson's disease. The most commonly used classification is the Wright and Coefield classification. Periprosthetic fractures can be treated both, conservatively and operatively. Conclusion Periprosthetic fracture frequency after shoulder arthroplasty ranges from 0 to 47.6%. The most common location of the fracture is the humerus and most commonly occurs intraoperatively. The most important factor influencing treatment is stem stability. Fractures with stem instability require revision arthroplasty with stem replacement. Fractures with a stable stem depending on the location, displacement and bone stock quality can be treated both conservatively and operatively. For internal fixation plates with cables and screws are most commonly used.

Abstract
BACKGROUND Much of the literature on osteonecrosis has traditionally focused on the hip, which remains the most common site for this disease. The shoulder and the knee are the second most frequently affected sites (both approximately 10% of the incidence). There are a variety of techniques for managing this disease, and it is important to optimize this for our patients. This review aimed to compare the results of core decompression (CD) vs. nonoperative modalities for the treatment of osteonecrosis of the humeral head, including (1) success rate defined as lack of progression to further procedures (shoulder arthroplasty) and no need for further intervention; (2) clinical results (patient-reported pain and functional scores); and (3) radiological outcomes. METHODS We queried PubMed and found 15 reports that fit the inclusion criteria for studies concerning the use of CD as well as studies discussing nonoperative treatment for stage I-III osteonecrotic lesions of the shoulder. A total of 9 studies encompassed 291 shoulders that underwent CD analyzed at a mean follow-up of 8.1 years (range, 67 months-12 years), and 6 studies examined 359 shoulders that underwent nonoperative management at a mean follow-up of 8.1 years (range, 35 months-10 years). Outcomes of CD and nonoperative management included success rate, number of shoulders requiring shoulder arthroplasty, and evaluation of several normalized patient-reported outcomes. We also assessed radiographic progression (pre- to postcollapse or further collapse progression). RESULTS The mean success rate of CD for avoiding further procedures was 76.6% (226 of 291 shoulders) in stage I through stage III. Stage III shoulders avoided shoulder arthroplasty in 63% (27 of 43 shoulders). Nonoperative management resulted in a success rate of 13%, P < .001. In the CD studies, 7 of 9 showed improvements in clinical outcome measurements compared with 1 of 6 of the nonoperative studies. Radiographically, there was less progression in the CD group (39 of 191 shoulders [24.2%]) vs. the nonoperative group (39 of 74 shoulders [52.3%]) (P < .001). CONCLUSIONS Given the high success rate and positive clinical outcomes reported, CD is an effective method for management, especially when compared with nonoperative treatment methods for stage I-III osteonecrosis of the humeral head. The authors believe that it should be used as treatment to avoid arthroplasty in patients who have osteonecrosis of the humeral head.

Abstract
Posterior dislocation is a rather rare injury, often misdiagnosed. The current report offers valuable insights regarding the anatomical background of this clinical entity and emphasizes the 'light-bulb sign,' which can be observed in anterior-posterior shoulder X-rays when there is a posterior dislocation. It is crucial for healthcare professionals, including emergency department physicians, radiologists, general practitioners, orthopedic surgeons, and other relevant medical experts, to be well-acquainted with this sign and maintain a heightened awareness when encountering such cases. A 57-year-old male presented to the Emergency Department due to right shoulder pain immediately after an epileptic seizure. His arm was locked in internal rotation, while the initial X-rays, although did not reveal evident malalignment, showed the light-bulb sign. Further imaging with a computer tomography (CT) scan exhibited a large (50%) reverse Hill-Sachs defect. The patient was treated surgically with hemiarthroplasty. The light-bulb sign should be a red flag for physicians who evaluate these patients or these X-rays. The patient's history, such as epileptic seizures and examination, especially the locked arm in internal rotation, are of paramount importance for not misdiagnosing these cases.

Abstract
BACKGROUND Accurate and rapid identification of implant manufacturer and model is critical in the evaluation and management of patients requiring revision total shoulder arthroplasty (TSA). Failure to correctly identify implant designs in these circumstances may lead to delay in care, unexpected intraoperative challenges, increased morbidity, and excess health care costs. Deep learning (DL) permits automated image processing and holds the potential to mitigate such challenges while improving the value of care rendered. The purpose of this study was to develop an automated DL algorithm to identify shoulder arthroplasty implants from plain radiographs. METHODS A total of 3060 postoperative images from patients who underwent TSA between 2011 and 2021 performed by 26 fellowship-trained surgeons at 2 independent tertiary academic hospitals in the Pacific Northwest and Mid-Atlantic Northeast were included. A DL algorithm was trained using transfer learning and data augmentation to classify 22 different reverse TSA and anatomic TSA prostheses from 8 implant manufacturers. Images were split into training and testing cohorts (2448 training and 612 testing images). Optimized model performance was assessed using standardized metrics including the multiclass area under the receiver operating characteristic curve (AUROC) and compared with a reference standard of implant data from operative reports. RESULTS The algorithm classified implants at a mean speed of 0.079 seconds (±0.002 seconds) per image. The optimized model discriminated between 8 manufacturers (22 unique implants) with AUROCs of 0.994-1.000, accuracy of 97.1%, and sensitivities between 0.80 and 1.00 on the independent testing set. In the subset of single-institution implant predictions, a DL model identified 6 specific implants with AUROCs of 0.999-1.000, accuracy of 99.4%, and sensitivity >0.97 for all implants. Saliency maps revealed key differentiating features across implant manufacturers and designs recognized by the algorithm for classification. CONCLUSION A DL model demonstrated excellent accuracy in identifying 22 unique TSA implants from 8 manufacturers. This algorithm may provide a clinically meaningful adjunct in assisting with preoperative planning for the failed TSA and allows for scalable expansion with additional radiographic data and validation efforts.

Abstract
BACKGROUND Parkinson disease (PD) is an established risk factor for higher rates of complications and revision surgery following shoulder arthroplasty, yet the economic burden of PD remains to be elucidated. The purpose of this study is to compare rates of complication and revisions as well as inpatient charges for shoulder arthroplasty procedures between PD and non-PD patients using an all-payer statewide database. METHODS Patients undergoing primary shoulder arthroplasty from 2010 to 2020 were identified from the New York (NY) Statewide Planning and Research Cooperative System (SPARCS) database. Study groups were assigned based on concomitant diagnosis of PD at the time of index procedure. Baseline demographics, inpatient data, and medical comorbidities were collected. Primary outcomes measured were accommodation, ancillary, and total inpatient charges. Secondary outcomes included postoperative complication and reoperation rates. Logistic regression was performed to evaluate effect of PD on shoulder arthroplasty revision and complication rates. All statistical analysis was performed using R. RESULTS A total of 39,011 patients (429 PD vs. 38,582 non-PD) underwent 43,432 primary shoulder arthroplasties (477 PD vs. 42,955 non-PD) with mean follow-up duration of 2.9 ± 2.8 years. The PD cohort was older (72.3 ± 8.0 vs. 68.6 ± 10.4 years, P < .001), with greater male composition (50.8% vs. 43.0%, P = .001), and higher mean Elixhauser scores (1.0 ± 4.6 vs. 7.2 ± 4.3, P < .001). The PD cohort had significantly greater accommodation charges ($10,967 vs. $7,661, P < .001) and total inpatient charges ($62,000 vs. $56,000, P < .001). PD patients had significantly higher rates of revision surgery (7.7% vs. 4.2%, P = .002) and complications (14.1% vs. 10.5%, P = .040), as well as significantly higher incidences of readmission at 3 and 12 months postoperatively. After controlling for age and baseline comorbidities, PD patients had 1.64 times greater odds of reoperation compared to non-PD patients (95% CI 1.10, 2.37; P = .012) and a hazard ratio of 1.54 for reoperation when evaluating revision-free survival following primary shoulder arthroplasty (95% CI 1.07, 2.20; P = .019). CONCLUSIONS PD confers a longer length of stay, higher rates of postoperative complications and revisions, and greater inpatient charges in patients undergoing TSA. Knowledge of the associated risks and resource requirements of this population will aid surgeons in their decision making as they continue to provide care to a growing number of patients affected by PD.

Abstract
BACKGROUND Reports on long term outcomes and failures of shoulder arthroplasty are uncommon. The purpose of this study is to present minimum 10-year outcomes in consecutive patients undergoing ream-and-run and anatomic total shoulder arthroplasty (TSA) for primary glenohumeral arthritis. METHODS This study analyzed consecutive patients that had undergone a ream-and-run or TSA with minimum 10-year follow-up. Pain scores and Simple Shoulder Test (SST) values were obtained preoperatively and at a minimum of 10 years postoperatively via e-mail or mail-in response. Percentage of maximum possible improvement (%MPI) was also calculated. RESULTS Of 127 eligible patients, 63 (50%) responded to a 10-year survey. This included 34 patients undergoing ream-and-run arthroplasty and 29 patients undergoing TSA. The ream-and-run patients were significantly younger than the TSA patients (60 ± 7 vs 68 ± 8, p<0.001), predominantly male (97% vs 41%, p<0.001), and had a lower American Society of Anesthesiologists classification (p=0.018). In the ream-and run group, the mean pain score improved from a preoperative value of 6.5 ± 1.9 to 0.9 ± 1.3 (p < 0.001), and the mean SST score improved from 5.4 ± 2.4 to 10.3 ± 2.1 at 10-year follow-up (p < 0.001). Twenty-eight (82%) achieved an SST improvement above the MCID of 2.6. Four patients (12%) underwent single-stage exchange to another hemiarthroplasty, while 1 (3%) required manipulation under anesthesia. In the TSA group, the pain score improved from a preoperative value of 6.6 ± 2.2 to 1.2 ± 2.3 (p < 0.001), and the SST score improved from 3.8 ± 2.6 to 8.9 ± 2.6 at 10-year follow-up. (p < 0.001). Of the 29 patients who underwent a TSA, 27 (93%) achieved an SST improvement above the MCID of 1.6. No patient in the TSA group required reoperation. CONCLUSION While the characteristics of the patients differ between the two groups, excellent functional results can be obtained with the ream-and-run arthroplasty and total shoulder arthroplasty for glenohumeral osteoarthritis.

Abstract
Background The treatment of shoulder prosthetic joint infections (PJIs) requiring removal of the prosthesis is not well defined. This article aims to systematically review and compare the results of the literature in single-stage and two-stage protocols in the treatment of shoulder PJI. Methods An in-depth search on PubMed/Scopus/Web of Science databases and cross-referencing search was carried out concerning the articles reporting detailed data on the topic. Results A total of 486 shoulder PJIs were included: 137 treated with single-stage and 349 with two-stage procedure. A similar distribution between early and not-early infections (19.1% vs 80.9%) was found between the two groups. The overall rate of success in terms of PJI eradication was significantly higher in the single-stage group (95.6% vs 85.7%, p < 0.001). The non-infection-related complications rate was 13.8% in the single-stage group and 37.6% in the two-stage group (p < 0.001), the non-infection-related revision rate was 8% and 18.9%, respectively (p = 0.005). Discussion The single-phase protocol showed a higher success rate in eradicating the infection and a lower complication rate. However, the low number of patients included, the low quality of the articles, the lack of data on clinical severity and bacteriological virulence suggest caution in conclusions.

Abstract
Introduction Shoulder arthroplasty is mostly performed as an inpatient procedure. Same-day discharge arthroplasty has shown positive results in hip and knee surgery. Primary objective of this study was to investigate whether a safe and satisfactory same-day discharge (SDD) can be predicted with a set of easy to use predefined criteria, without increasing complications and re-admissions. Methods This study was a prospective cohort study. Patient selection criteria were: <85 years old, ASA 1, 2, and mild ASA 3. Primary outcome variables were successful SDD, complications, re-admissions and patient satisfaction. Secondary outcomes were patient-reported outcome scores. The results are compared with the inpatient cohort. Results In total, 163 patients were treated for elective shoulder arthroplasty. Of which 51 patients were selected for same-day discharge arthroplasty. 94% of pre-planned same-day discharge arthroplasty patients were discharged on the day of surgery. In the same-day discharge group, there were no complications related to the early discharge and a 2% readmission rate as opposed to a 3% readmission rate in the inpatient group. Surgery related as well as medical complications did not differ between the same-day discharge and inpatient cohort. Discussion Same-day discharge shoulder arthroplasty is a safe and satisfying treatment option in selected patient groups.

Abstract
BACKGROUND Prospective trial registration has become an important means of improving the transparency and reproducibility of randomized controlled trials (RCTs) and is recommended by the Journal of Shoulder and Elbow Surgery (JSES) per the Consolidated Standards of Reporting Trials (CONSORT) guidelines. Herein, we performed a cross-sectional evaluation of RCTs published in JSES from 2010 to present to determine the prevalence of trial registration and consistency of outcome reporting. METHODS The electronic database PubMed was searched to identify all RCTs on total shoulder arthroplasty (TSA) published in JSES from 2010 to 2022 using the search terms "randomized controlled trial" AND "shoulder" AND "arthroplasty OR replacement." RCTs were considered to be registered if they provided a registration number. For articles that were registered, authors also extracted the registry name, registration date, date of first enrollment, date of last enrollment, and if the primary outcomes reported in the registry were either (1) omitted, (2) newly introduced in the publication, (3) reported as a secondary outcome or vice versa, or (4) varied in timing of assessment compared to the publication. "Early" RCTs were considered those published from 2010 to 2016, whereas "later" RCTs were from 2017 to 2022. RESULTS Fifty-eight RCTs met inclusion criteria. There were 16 early RCTs and 42 later RCTs. Twenty-three of the 58 (39.7%) studies were registered, with 9 of 22 with an available registry (40.9%) of those being enrolled prior to patient enrollment. Nineteen of the registered studies (82.6%) provided the name of the registry and a registration number. The proportion of later RCTs that were registered was not significantly different from the early RCTs (45.2% vs. 25.0%, P = .232). Seven RCTs (31.8%) had at least 1 inconsistency compared with the registry. The most common discrepancy was the timing of the assessment (ie, follow-up period) reported in the publication vs. the registry. DISCUSSION Although JSES recommends prospective trial registration, less than half of shoulder arthroplasty RCTs are registered and more than 30% registered trials have at least 1 inconsistency with their registry record. More rigorous review of trial registration and accuracy is necessary to limit bias in published shoulder arthroplasty RCTs.

Abstract
Background Treatment of glenohumeral osteoarthritis (GHOA) may include conservative management with use of intraarticular injections, prior to considering total shoulder arthroplasty (TSA). The purpose of this study was to assess trends in the use of preoperative cortisone (CO) and hyaluronic acid (HA) injections, as well as investigate the relationship between injection use and infection or revision arthroplasty following TSA. Methods Pearl Driver was used to identify all patients undergoing TSA for GHOA between 2010 and 2018. Patients were categorized based on the type and number of injections they received. Outcomes of interest included post-operative opioid use, post-operative infection, and risk of revision surgery within 1 year of the index procedure. Results The incidence of patients receiving a CO or HA injections within 1 year of their TSA decreased by 83% and 54%, respectively. Patients who had received 1 or more steroid injections had higher odds of prolonged opiate use following surgery. Patients that received 1 or 2 CO injection prior to TSA had an increased risk of needing revision surgery. Discussion Use of intraarticular injections for the management of GHOA has declined. Patients receiving preoperative injections had increased odds of prolonged opiate use and the need for revision surgery.

Abstract
BACKGROUND Over the last few decades, several databases and clinical registries have been used to generate studies for orthopedic surgery research including shoulder arthroplasty. Observational database studies present data that are best used to provide information regarding associations between variables but is unable to prove causation. Yet, there remains a tendency for authors to use causal language and conclusive statements in published shoulder arthroplasty literature using such databases. METHODS We systematically identified administrative database and registry studies on shoulder arthroplasty in 5 orthopedic journals from January 2020 to December 2021. Papers were independently graded by 2 reviewers for the presence, absence, or inconsistent use of causal language throughout the publication. χ2 analyses were conducted to determine the relationship between causality language and article characteristics including the journal of publication. RESULTS There were 65 eligible articles. According to the reviewers, 67.7% of titles and abstracts were either consistently causal or inconsistently causal in language and inference. On reviewing the full text, 69.2% were found to contain some degree of causal language (38.5% consistently causal, 30.8% inconsistently causal). There were no statistically significant associations between the journal and title and abstract final grading (P = .863) or the journal and full-text grading (P = .726). CONCLUSION The use of causal language remains highly prevalent in observational database studies related to shoulder arthroplasty. Understanding the limitations of observational database studies is paramount for accurate interpretation of these publications.

Abstract
Background Tobacco carcinogens have adverse effects on bone health and are associated with inferior outcomes following orthopedic procedures. The purpose of this study was to assess the impact tobacco use has on readmission and complication rates following shoulder arthroplasty. Methods The 2016-2018 National Readmissions Database was queried to identify patients who underwent anatomical, reverse, and hemi-shoulder arthroplasty. ICD-10 codes Z72.0 × (tobacco use disorder) and F17.2 × (nicotine dependence) were used to define "tobacco-users." Demographic, 30-/90-day readmission, surgical complication, and medical complication data were collected. Inferential statistics were used to analyze complications for both the cohort as a whole and for each procedure separately (i.e. anatomical, reverse, and hemiarthroplasty). Results 164,527 patients were identified (92% nontobacco users). Tobacco users necessitated replacement seven years sooner than nonusers (p < 0.01) and were more likely to be male (52% vs. 43%; p < 0.01). Univariate analysis showed that tobacco users had higher rates of readmission, revisions, shoulder complications, and medical complications overall. In the multivariate analysis for the entire cohort, readmission, revision, and complication rates did not differ based on tobacco usage; however, smokers who underwent reverse shoulder arthroplasty in particular were found to have higher 90-day readmission, dislocation, and prosthetic complication rates compared to nonsmokers. Conclusion Comparatively, tobacco users required surgical correction earlier in life and had higher rates of readmission, revision, and complications in the short term following their shoulder replacement. However, when controlling for tobacco usage as an independent predictor of adverse outcomes, these aforementioned findings were lost for the cohort as a whole. Overall, these findings indicate that shoulder replacement in general is a viable treatment option regardless of patient tobacco usage at short-term follow-up, but this conclusion may vary depending on the replacement type used.

Abstract
Introduction The most common surgical options for geriatric proximal humerus fractures are open reduction and internal fixation (ORIF), hemiarthroplasty (HA), and reverse total shoulder arthroplasty. We used a longitudinal inpatient discharge database to determine the cumulative incidence of conversion to arthroplasty after ORIF of geriatric proximal humerus fractures. The rates of short-term complications and all-cause reoperation were also compared. Patients and Methods All patients 65 or older who sustained a proximal humerus fracture and underwent either ORIF, HA, or shoulder arthroplasty (SA) as an inpatient from 2000 through 2017 were identified. Survival analysis was performed with ORIF conversion to arthroplasty and all-cause reoperation as the endpoints of interest. Rates of 30-day readmission and short-term complications were compared. Trends in procedure choice and outcomes over the study period were analyzed. Results A total of 27 102 geriatric patients that underwent inpatient surgical management of proximal humerus fractures were identified. Among geriatric patients undergoing ORIF, the cumulative incidence of conversion to arthroplasty within 10 years was 8.2%. The 10-year cumulative incidence of all-cause reoperation was 12.1% for ORIF patients and less than 4% for both HA and SA patients. Female sex was associated with increased risk of ORIF conversion and younger age was associated with higher all-cause reoperation. ORIF was associated with higher 30-day readmission and short-term complication rates. Over the study period, the proportion of patients treated with ORIF or SA increased while the proportion of patients treated with HA decreased. Short-term complication rates were similar between arthroplasty and ORIF patients in the later cohort (2015-2017). Conclusion The 10-year cumulative incidence of conversion to arthroplasty for geriatric patients undergoing proximal humerus ORIF as an inpatient was found to be 8.2%. All-cause reoperations, short-term complications, and 30-day readmissions were all significantly lower among patients undergoing arthroplasty, but the difference in complication rate between arthroplasty and ORIF was attenuated in more recent years. Younger age was a risk factor for reoperation and female sex was associated with increased risk of requiring conversion to arthroplasty after ORIF.

Abstract
OBJECTIVE This systematic review aimed to determine whether obesity has a negative impact on the incidence of complications and functional scores of all types of shoulder arthroplasty. METHODS Electronic databases such as PubMed, Embase, Web of Science, and Cochrane were systematically searched for publications concerning obesity and shoulder arthroplasty. The Newcastle-Ottawa scale criteria were used to evaluate the study's quality. A total of 15 studies were identified involving total shoulder arthroplasty, reverse total shoulder arthroplasty, or hemiarthroplasty. The studies com- paring the outcome of shoulder arthroplasty in different weight groups were conducted after the search of related literature and grouped according to different weights and compared with each other. Counted data used odds ratio value and its 95% CI for data analysis, and measurement data used weighted mean difference and its 95% CI for statistical analysis. RESULTS The remaining 12 articles met the inclusion criteria and were included in this review. Any infection was reported in 6 studies, including 197 013 patients. Infections were more likely to occur in obese patients, with an odds ratio of 3.38 (95% CI, 2.28-5.02). The operation time of overweight patients (body mass index >25 kg/m2) was significantly longer than that of normal-weight patients (odds ratio, 6.90; 95% CI, 3.79-10.00). The venous thromboembolism was more likely to occur in obese patients (odds ratio, 3.39; 95% CI, 3.6- 4.28). In addition, there was no significant difference in the dislocation rate and revision rate of prostheses among the groups. Patients who undergo shoulder arthroplasty could obtain a good American Shoulder and Elbow Surgeons score (Mean Difference [MD], 1.87; 95% CI, -2.08 to 5.82), regardless of their body mass index. CONCLUSION Obesity had a negative impact on the prognosis of patients treated with shoulder arthroplasty. Additionally, obese patients require longer surgical times than normal-weight patients, although all patients can attain positive functional outcomes. LEVEL OF EVIDENCE Level III, Therapeutic Study.

Abstract
Proximal humeral fractures (PHFs) are a common type of fracture, particularly in older adults, accounting for approximately 5-6% of all fractures. This article provides a comprehensive review of PHFs, focusing on epidemiology, injury mechanism, clinical and radiographic assessment, classification systems, and treatment options. The incidence of PHFs varies across regions, with rates ranging from 45.7 to 60.1 per 100,000 person-years. Females are more susceptible to PHFs than males, and the incidence is highest in women over the age of 85. The injury mechanism of PHFs is typically bimodal, with high-energy injuries predominant in younger individuals and low-energy injuries in the elderly. Clinical assessment of PHFs involves obtaining a thorough history, physical examination, and evaluation of associated injuries, particularly neurovascular injuries. Radiographic imaging helps assess fracture displacement and plan for treatment. The Neer classification system is the most commonly used classification for PHFs, although other systems, such as AO/OTA, Codman-Hertel, and Resch classifications, also exist. The choice of treatment depends on factors such as patient age, activity level, fracture pattern, and surgeon expertise. Nonoperative management is typically preferred for elderly patients with minimal displacement, while operative fixation is considered for more complex fractures. Nonoperative treatment involves sling immobilization followed by physiotherapy, with good outcomes reported for certain fracture patterns. Operative management options include closed reduction and percutaneous pinning (CRPP), open reduction and internal fixation (ORIF), or arthroplasty. CRPP is suitable for specific fracture patterns, but the quality of reduction is crucial for favorable outcomes. ORIF is used when CRPP is not feasible, and various surgical approaches are available, each with its advantages and potential complications. PHFs are a significant clinical challenge due to their prevalence and complexity. Treatment decisions should be patient centered based on patient factors and fracture severity.
