title: Thumb carpometacarpal joint total arthroplasty: a systematic review.
abstract: Thumb carpometacarpal joint total arthroplasty has been undertaken for many years. The proponents believe the short-term outcomes are better than trapeziectomy and its variants, but the longer term complications are often higher. This systematic review of all peer reviewed articles on thumb carpometacarpal joint total arthroplasty for osteoarthritis shows that there are reports of many implants. Some are no longer available. The reported outcomes are very variable: for some there are good long-term outcomes to beyond 10 years ; for others there are unacceptably high early rates of failure. Overall the published evidence does not show that total arthroplasty is better than trapeziectomy and its variants yet there is a higher complication rate and significant extra cost of using an implant. Future research needs to compare total arthroplasty with trapeziectomy to assess short term results where the arthroplasties may be better, long-term outcomes and the healthcare and personal costs so that surgeons and patients can make fully informed choices about the treatment of symptomatic thumb carpometacarpal joint osteoarthritis.
