Outcomes After Hemiarthroplasty for Proximal Humerus XXXX Are Significantly Affected by Hand Dominance.

@entity174 @entity1 @entity227 @entity130
OBJECTIVES: Hand dominance has been reported to be an important factor affecting outcomes after upper extremity @entity130 but remains unstudied after hemiarthroplasty for @entity174 . This study determined whether dominance affected outcomes after hemiarthroplasty for @entity174 . DESIGN: Retrospective cohort study. SETTING: Tertiary care referral center. @entity1 : Sixty-one @entity1 , after hemiarthroplasty for @entity174 , returned for comprehensive assessment and were divided into 2 groups: dominant (DOM) shoulder affected (n = 25) and non-dominant (non-DOM) shoulder affected (n = 36). INTERVENTION: @entity174 -specific proximal humeral hemiarthroplasty for displaced @entity174 . MAIN OUTCOME MEASURES: @entity1 were assessed with self-reported outcomes ( @entity227 , American Shoulder and Elbow Surgeons shoulder score, disability of the arm, shoulder, and hand questionnaire, simple shoulder test, and short form 12) and objective (range-of-motion and hand-held dynamometer strength) testing. RESULTS: At 49 months of mean follow-up, there were no significant differences between groups for gender, age, follow-up time, or @entity227 (P > 0.256). The DOM-affected group had significantly worse scores for American Shoulder and Elbow Surgeons shoulder score (P = 0.043), disability of the arm, shoulder, and hand questionnaire (P = 0.039), and simple shoulder test (P = 0.021). The DOM-affected group also had consistently higher correlations between self-reported and objective outcomes than the non-DOM group. CONCLUSIONS: @entity1 who underwent hemiarthroplasty for @entity174 on their DOM shoulders had significantly poorer outcomes than @entity1 with non-DOM-sided injuries. Although positive outcomes can be expected after hemiarthroplasty, @entity1 should be instructed that they may have less satisfactory function and strength if their injury was on the DOM side. LEVEL OF EVIDENCE: Prognostic Level II. See Instructions for Authors for a complete description of levels of evidence.
