Brief Summary

Total wrist arthroplasty (TWA) surgery has developed gradually and can offer patients with rheumatoid arthritis/osteoarthritis reduced wrist pain with mainly preserved wrist range of movement. Each year 60-70 patients in Sweden are operated with a total wrist arthroplasty. Several implants are available on the market and they all have different pros and cons. One risk with a total wrist arthroplasty is loosening of the implant. If an implant is loose, revision of the implant to another TWA is sometimes possible, if not, a wrist fusion is the likely alternative. Revision rates five years after the index operation have improved, however, they cannot yet compare with the results after a total hip arthroplasty. A newly designed TWA has been developed by the department of Hand Surgery, Örebro university Hospital, Örebro, Sweden, in cooperation with Trimed Inc. The newly developed TWA offers theoretical advantages and has been biomechanically tested at the Mayo clinic. This is a pilot study where patients operated with the TWA will be assessed pre and postoperatively according to study protocol in order to evaluate outcome after TWA radiologically, clinically and regarding patient perceived outcome measures.
