Re-motion total wrist arthroplasty: 39 non-rheumatoid cases with a mean follow-up of 7 years.

We evaluated the outcomes of the Re-motion total wrist arthroplasty in 39 non-rheumatoid patients. The mean follow-up was 7 years (range 3-12). Postoperative wrist flexion-extension and radial-ulnar deviation as well as the scores of the Disability of Arm Shoulder and Hand questionnaire and the visual analogue scale pain scores improved significantly. Complications occurred in 13 wrists, five of which required further surgery. The most frequent complication was impingement between the scaphoid and the radial implant (n = 5), which can be avoided by complete or almost complete scaphoid resection. Periprosthetic radiolucency developed around the radial component in three cases and three radial screws loosened. Despite the incidence of high implant survival in 38 of 39 wrists over 7 years (97%), the complication rate is not satisfying. Knowledge of the risk of complications and patient selection are essential when making the decision to choose wrist arthroplasty over arthrodesis. IV.
