Biaxial total wrist arthroplasty in rheumatoid arthritis. Satisfactory functional results.
We reviewed 16 uncemented biaxial total wrist arthroplasties (TWA) in 14 patients with rheumatoid or juvenile arthritis. The mean follow-up was 25 months (range 5-60). According to the Hospital for Special Surgery scoring system (HSS), good-to-excellent results were accomplished in 69%, moderate in 19%, and poor in 12%. The mean pain score was 0.4 on a visual analog scale from 0-10 (0=no pain). The Wrightington activities of daily life assessment chart showed a 63% improvement, and we found a threefold increase in range of motion at follow-up. Four TWAs showed early dislocation, one of which was revised. Biaxial TWA yields good short-term results in rheumatoid patients, although instability is a frequent complication.
