Proximal humerus fractures should be treated with a reverse shoulder replacement

Historically, fractures of the proximal humerus not amendable to closed treatment or internal fixation have been treated with hemiarthroplasty. Clinical outcomes following hemiarthroplasty have been variable and difficult to predict. Results are often correlated with increasing age, tuberosity healing, and tuberosity position. Reverse shoulder arthroplasty has demonstrated effectiveness in elderly patients with rotator cuff arthropathy and has been increasingly employed for complex fractures in older patients. Several small trials have compared the reverse arthroplasty and hemiarthroplasty for acute fractures, and reverse shoulder arthroplasty has demonstrated more reproducible results in elderly patients.
