The purpose of this study is to assess the early outcomes following Reverse Shoulder Arthroplasty (RSA) in patients sixty years or younger for the purpose of characterizing these patients, evaluating their clinical outcomes and radiographic appearance.We would like to know how quickly they are healing and returning to their baseline activities of daily living and ability to work. This will help when counseling patients prior to surgery as it will give us a better defined and study supported understanding of the post-operative recovery timeline in the younger population.
