title: Implant arthroplasty of the carpometacarpal joint of the thumb.
abstract: Resection arthroplasty with or without ligament reconstruction for thumb trapeziometacarpal arthritis can be complicated by thumb shortening and pinch-strength weakness. Implant arthroplasties have been developed to limit loss of thumb length, improve strength, and limit postoperative convalescence. The ideal thumb carpometacarpal implant should be strong and stable, provide full range of motion, and prevent loosening. Unfortunately, no current prosthesis accomplishes all of these goals. Until the ideal implant is developed, clinical acumen must be used to determine appropriate patients and implants.
