Abstrakt:	Purpose: To compare outcomes, between stemmed and stemless reverse shoulder arthroplasty (RSA) at a minimum follow-up of 5 years. Methods: The authors retrospectively assessed a consecutive series of 45 patients that underwent RSA between September 2014 and October 2018 (23 stemless and 22 stemmed). All patients underwent plain anteroposterior and scapular Y-view radiographs for assessment immediately post-operatively and at final follow-up. At a minimum follow-up of 5 years, an independent observer assessed the clinical scores, including Constant score, QuickDASH score, and American Shoulder and Elbow Surgeons score. Results: Of the 45 patients that underwent RSA, 5 patients died (11%), 2 were revised due to infection (4%), and 4 patients were lost to follow-up (9%). This left a final cohort of 34 patients (18 stemless and 16 stemmed). Significant differences between groups were found immediately post-operatively for lateralisation shoulder angle (LSA) (p = 0.021), but at 5 years post-operative for distalisation shoulder angle (DSA) (p = 0.017) and QuickDASH scores (p = 0.041) (Table 4), while the outcomes were comparable for absolute Constant scores, ASES score, and range of motion. Finally, stemless RSA had a 17% complication rate, while stemmed RSA had a 31% complication rate. Conclusion: Stemless RSA had significantly more lateralisation, and significantly less distalisation, compared to stemmed RSA. Furthermore, at a 5-year follow-up, stemless RSA granted significantly greater QuickDASH scores. Finally, stemless RSA had comparable complication rates as stemmed RSA. The clinical relevance of this study is that stemless RSA is a safe alternative to stemmed RSA, while granting comparable or greater scores. Level of Evidence: III, Comparative Study.
