Prior studies have largely focused on total shoulder arthroplasty, leaving limited data on outcomes across a broader range of elective shoulder procedures. This study aimed to compare postoperative outcomes between septuagenarians and octogenarians undergoing elective shoulder surgery.</p><p><strong>Methods: </strong>The American College of Surgeons National Surgical Quality Improvement Program database (2011-2022) was queried for patients aged 70-89 years undergoing elective shoulder procedures, and patients were stratified into septuagenarians (70-79 years) and octogenarians (80-89 years). Multivariable logistic regression analyses adjusted for demographic and clinical covariates were used to assess postoperative outcomes.</p><p><strong>Results: </strong>A total of 12,099 patients were included, comprising 10,810 septuagenarians (89%) and 1289 octogenarians (11%). After adjustment, octogenarians had higher odds of unplanned readmission (OR 1.57, 95% CI 1.04-2.29; <i>p</i> = 0.026) and non-home discharge (OR 2.44, 95% CI 1.57-3.72; <i>p</i> < 0.001). No significant differences were observed in overall complications, reoperation, or 30-day mortality.</p><p><strong>Discussion: </strong>Octogenarians undergoing elective shoulder procedures are at increased risk for readmission and non-home discharge despite similar short-term complication rates. These findings underscore the importance of perioperative planning and discharge optimization in this population.</p>","PeriodicalId":36705,"journal":{"name":"Shoulder and Elbow","volume":" ","pages":"17585732261467911"},"PeriodicalIF":1.2,"publicationDate":"2026-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13354589/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148424951","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}
