Update on Shoulder Arthroplasty Abstract. Shoulder arthroplasty is indicated for treatment of primary osteoarthritis, cuff tear athropathy, complex proximal humerus fractures, and posttraumatic situations. The rotator cuff plays an important role. In case of an intact rotator cuff, anatomical shoulder arthroplasty is preferred. Over the past decades, the number of hemi prostheses has declined in favor of total shoulder arthroplasties. Reverse shoulder arthroplasty is used for severe and irreparable rotator cuff tears, advanced cuff tear athropathy, and increasingly for complex proximal humerus fractures. Reverse shoulder arthroplasties account for almost 80 % of all shoulder prostheses. Modern implants allow conversion from an anatomic to a reverse situation if needed. Improved understanding of the pathology, new implant designs, and preoperative 3D planning have improved the overall outcome.
