The proposed study is a prospective, single-blinded, randomized trial to investigate the impact of humeral component version on shoulder range of motion and patient reported functional outcomes following reverse total shoulder arthroplasty.
Retrospective clinical evidence suggests that increasing humeral component retroversion does not affect measured internal or external rotation, however patients with neutral version may experience better function with daily activities requiring internal rotation compared to those with 30 degrees of retroversion. Prospective data on clinical outcomes comparing different humeral component versions in RTSA is currently lacking. The proposed study is a prospective, single-blinded, randomized trial to investigate the impact of humeral component version on shoulder range of motion and patient reported functional outcomes following reverse total shoulder arthroplasty.
