Effect of Hand Dominance on Range of Motion and Outcomes Following Reverse Total Shoulder Arthroplasty

IntroductionUpper extremity hand dominance greatly impacts the functional ability to perform activities of daily living. No studies have evaluated the effects of hand dominance on patient outcomes and postoperative range of motion (ROM) after reverse total shoulder arthroplasty (rTSA).MethodsFrom 2009 to 2014, functional data and patient-reported outcomes were prospectively collected from patients who underwent rTSA at a single institution. Baseline characteristics were assessed and patients were stratified based on whether surgery was performed on the dominant extremity. A repeated-measures ANOVA was performed to determine differences in outcomes between cohorts.ResultsEighty-seven rTSAs were performed on the patients’ dominant (DO) shoulder and 53 on the nondominant (ND) shoulder. Both groups had similar age, hospital length of stay, body mass index, and Charlson Comorbidity Index. Prior to surgery, the ND group had significantly lower active forward elevation (FE) (68°) compared to the DO group (87°, P...
