Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Reverse shoulder arthroplasty for the treatment of rotator cuff deficiency and glenohumeral arthritis have shown favorable outcomes in pain and function over the short and medium term. A prospective, multi-center study on the outcomes of subjects treated with the RSP would be a valuable addition to the literature and give important information regarding an ever-increasing treatment option for subjects with rotator cuff deficiency. The study will take place at multiple sites across the United States and will be managed by the DJO Surgical Clinical Affairs Department. The study will include only subjects who meet the indications for use criteria for the Reverse® Shoulder Prosthesis and who are candidates for total shoulder replacement surgery.
