Restoring native shoulder kinematics may be an important consideration for implant longevity and ultimate shoulder function, but &lt;em&gt;in-vivo&lt;/em&gt; assessment and comparisons have been historically difficult. The purpose of this study was to compare scapulohumeral rhythm (SHR) between aTSA and rTSA when performed for patients with cuff-intact osteoarthritis and compare these with preoperative values and normal controls.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Methods&lt;/h3&gt;&lt;div&gt;A retrospective analysis was performed on 71 shoulders that underwent arthroplasty for cuff-intact osteoarthritis, aTSA (n = 28) and rTSA (n = 43), who had dynamic digital radiography performed more than 6 months postoperatively and compared these to 32 normal controls. SHR was calculated by dividing the change in glenohumeral abduction (ΔH) by the change in scapular upward elevation (ΔS) using the formula SHR = ΔH/ΔS, across the total range of abduction below 120° and between the 0°-30°, 30°-60°, 60°-90°, and 90°-120° abduction intervals. A paired subgroup analysis was performed on 14 aTSA and 14 rTSA shoulders with both pre- and postoperative dynamic digital radiography.

Finally, the SCB values for ROC methods were 85.76 for ASES, 9.5 for Brophy, 92.25 for SSV, 2.5 for VAS, 14.5 for PROMIS-10 MH, and 14.5 for PROMIS-10 PH, respectively.</div></div><div><h3>Conclusion</h3><div>MCID, PASS, and SCB provide clinical context to PROMs, allowing a more accurate assessment of patient outcomes. The thresholds defined in this study can provide a guideline for interpreting patient outcomes following arthroscopic stabilization for posterior shoulder instability, allowing for earlier detection of recurrent posterior instability.</div></div>","PeriodicalId":34444,"journal":{"name":"JSES International","volume":"9 6","pages":"Pages 1959-1964"},"PeriodicalIF":0.0,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145468890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It aims to determine if MRI is accurate enough to identify or rule out these lesions.</div></div><div><h3>Methods</h3><div>To evaluate the diagnostic accuracy of MRI for SLAP lesions, we conducted a thorough search of the MEDLINE, Scopus, Web of Science, and Embase databases up to January 6, 2025. We included original studies that compared MRI findings with those of arthroscopy or open surgery (used as the reference standard). Stata and MetaDisc software were used for statistical analyses and the Quality Assessment of Diagnostic Accuracy Studies 2 tool was used to assess the quality of included studies.</div></div><div><h3>Results</h3><div>The meta-analysis included 33 studies from 30 original papers, encompassing 2,916 patients. The pooled sensitivity for MRI detection of SLAP lesions was 0.77 (95% confidence interval [CI], 0.65-0.86) and the specificity was 0.94 (95% CI, 0.89-0.97). Other pooled metrics included a positive likelihood ratio of 6.82 (95% CI, 4.06-11.45), negative likelihood ratio of 0.34 (95% CI, 0.25-0.45), diagnostic odds ratio of 23.62 (95% CI, 12.76-43.70), and an area under the curve of 0.94.</div></div><div><h3>Conclusion</h3><div>Our findings indicate that MRI exhibits moderate sensitivity and excellent specificity and accuracy, suggesting that MRI is a valuable tool for confirming SLAP lesions. However, it cannot definitively rule them out on its own. Therefore, arthroscopy and open surgery remain the gold standard for diagnosing these lesions.</div></div>","PeriodicalId":34444,"journal":{"name":"JSES International","volume":"9 6","pages":"Pages 1972-1987"},"PeriodicalIF":0.0,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145468887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
