Arthroplasty of the upper extremity is an established surgical intervention in the management of arthritis of the elbow, wrist and hand. The anatomy, kinematics and demands of the elbow, wrist, thumb CMC, and finger MCP and PIP joints pose unique surgical challenges. Implant design considerations are important in providing a joint that mimics the native joints and maximizes survivorship. However, outcomes are less predictable in these upper extremity joints when compared to the hips and knees. Each joint also carries its own set of potential complications and salvage options for revision and failed arthroplasty. This unique text helps the orthopedic and hand surgeon understand the surgical approaches, unique anatomic considerations, and both the historical and current designs related to each respective joint, enabling the surgeon to better appreciate the benefits and limitations of each arthroplasty. Presenting the current state of the art, the seven sections proceed anatomically from the elbow to the fingers, with each section comprised of three thematic chapters discussing implant design considerations, primary arthroscopy techniques and revision arthroscopy techniques, including non-surgical options for treating these often difficult problems. This consistent approach, accompanied by plentiful figures, radiographs and intraoperative photos, ensures that this will be a user-friendly resource for orthopedic and hand surgeons, residents and trainees.
