Although revision strategies have been described planned two-stage revision with custom implants has not previously been reported.Case presentation: A 55-year-old female presented with pain and dysfunction following RSA. Examination demonstrated severe motion limitation, while imaging revealed loosening and progressive bone loss. Intraoperatively, we identified extensive metallosis with micromotion at the modular humeral junction, and a large glenoid defect. The initial glenoid baseplate was also positioned relatively high, resulting in impingement and subsequent scapular notching, which may have contributed to the metallosis. Owing to extensive metallosis, severe osteolysis, poor bone stock, and uncertain infection status, a staged revision was performed. An antibiotic spacer was placed and glenoid was bone grafted. Eventually definitive reconstruction was performed using a custom glenoid baseplate and humeral component because standard revision implants could not achieve stable fixation. At 1 year, the patient had improved shoulder function with forward elevation of 130° and was able to perform activities of daily living.Conclusion: Catastrophic metallosis secondary to modular junction failure may require staged revision and patient-specific reconstruction when extensive bone loss precludes standard revision implants.","PeriodicalId":36705,"journal":{"name":"Shoulder and Elbow","volume":" ","pages":"17585732261495517"},"PeriodicalIF":1.2,"publicationDate":"2026-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13652974/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149169829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dynamic anterior stabilization (DAS) addresses this limitation by transferring the long head of the biceps (LHB) tendon after tenotomy at its articular origin through a subscapularis split and fixing it to the anterior glenoid rim. Although the DAS has shown favorable short-term results, its effectiveness may be reduced in cases with significant capsulolabral deficiency. To address this limitation, we present a modified technique, biceps augmentation DAS. This approach utilizes the intraarticular portion of the LHB tendon to provide additional biological augmentation in patients with subcritical bone loss and capsulolabral insufficiency. This technique combines on-lay fixation at the glenoid equator using knotless anchors with supplementary anteroinferior augmentation using the same anchors placed during Bankart repair.","PeriodicalId":36705,"journal":{"name":"Shoulder and Elbow","volume":" ","pages":"17585732261493462"},"PeriodicalIF":1.2,"publicationDate":"2026-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13650078/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149172201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Five databases were searched from inception to September 2026. Studies assessing isometric shoulder rotation torque, or force and moment arm, at three or more shoulder rotation angles in non-injured participants were included. Data extraction focused on torque-angle patterns, testing position, muscle activation, moment arms, limb dominance, and methodological characteristics.Results: Twelve studies were included. External rotation torque-angle curves were typically descending or ascending-descending, whereas internal rotation curves were predominantly ascending-descending. Peak torque was generally observed near mid-range positions. Only three studies assessed multiple shoulder positions within the same sample, and none directly evaluated shoulder rotator moment arms. Electromyographic data were limited, and methodological heterogeneity, incomplete bilateral assessment, and limited standardization were common.Conclusions: Shoulder rotator torque-angle relationships remain incompletely characterized and appear highly dependent on joint position and testing methodology. Current evidence suggests peak torque production near mid-range rotation, but substantial gaps remain regarding functional testing positions, bilateral comparisons, athletic populations, and underlying biomechanical mechanisms.","PeriodicalId":36705,"journal":{"name":"Shoulder and Elbow","volume":" ","pages":"17585732261495537"},"PeriodicalIF":1.2,"publicationDate":"2026-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13650075/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149172075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their impact on total shoulder arthroplasty (TSA) outcomes, however, remains poorly defined. The purpose of this study is to determine the effect of DFU on periprosthetic joint infection (PJI), deep wound infection, and sepsis in diabetic patients undergoing primary TSA.Methods: Using the PearlDiver Mariner database from 2010 to 2023, diabetic patients undergoing primary TSA were identified and stratified by DFU status using ICD-10 codes. Primary outcomes were postoperative sepsis, deep infection, and PJI at 90 days and 1 year. Multivariable logistic regression assessed the association between DFU status and postoperative complications.Results: Among 56,482 diabetic patients undergoing TSA, 2404 had DFU (4.3%). Compared with diabetics without DFU, DFU patients had significantly higher rates of sepsis at 90 days (1.62% vs 0.86%) and 1 year (5.86% vs 2.30%), PJI at 1 year (1.70% vs 1.09%), and deep infection at 1 year (0.67% vs 0.28%) (all p < 0.01).

Shoulder magnetic resonance imaging (MRI), already standard of care, offers an opportunity for opportunistic osteoporosis screening.Objective: To evaluate whether proximal humeral cortical bone thickness on shoulder MRI can predict osteoporosis in patients with rotator cuff tears (RCTs).Methods: A retrospective, cross-sectional study included 130 female patients (mean age 68.8 ± 8.9 years) who underwent shoulder MRI and dual-energy X-ray absorptiometry (DXA) within 6 months. Average cortical bone thickness (CBTavg) and cortical bone thickness index (CBTg) were measured on coronal T1-weighted images. Patients were classified per World Health Organization DXA criteria (T-score ≤ -2.5) at the femur, the lumbar spine and either site (all-site). Only female patients were eligible for inclusion; no male data were collected.Results: CBTavg and CBTg were significantly lower in osteoporosis groups across all classification schemes. For femur DXA, CBTavg at 4.5 mm achieved 100% sensitivity and 86% specificity (area under the curve (AUC) = 0.955). For all-site osteoporosis, CBTg at 0.26 yielded 100% sensitivity and 87.8% specificity (AUC = 0.958).Conclusion: MRI-derived proximal humeral cortical thickness is a promising osteoporosis screening tool in RCT patients. A CBTavg below 4.5 mm should prompt DXA referral, improving preoperative bone health assessment without added cost or radiation. These cut-offs require external validation before clinical implementation.","PeriodicalId":36705,"journal":{"name":"Shoulder and Elbow","volume":" ","pages":"17585732261491314"},"PeriodicalIF":1.2,"publicationDate":"2026-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13624193/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149115991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
