%X <B>OBJECTIVE: </B>To evaluate the longitudinal clinical outcomes using a new semiconstrained wrist prosthesis for the treatment of severe rheumatoid arthritis of the wrist.<BR><B>METHODS: </B>Twenty patients with rheumatoid arthritis (20 wrists) underwent total wrist arthroplasty with the prosthesis in a clinical trial. The preoperative Larsen classification was grade IV in 16 wrists and grade V in 4 wrists. Assessments were performed before surgery, 1.5 years after surgery, and at final follow-up (≥ 5 years after surgery) using the visual analog scale for pain, Figgie wrist score, Japanese version of the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, and plain radiographs.<BR><B>RESULTS: </B>At final follow-up, no patient had wrist pain. The preoperative flexion-extension arc at final follow-up was similar to the preoperative range. The mean 1.5-year postoperative Figgie score was significantly improved and was unchanged at final follow-up. The DASH score significantly improved from before surgery to 1.5 years after surgery; the DASH score was improved further at final follow-up, but not significantly. Five of the 19 wrists evaluated had radiographic findings indicating carpal component loosening at final follow-up; however, all patients with the loosening were asymptomatic and had not undergone revision surgery.<BR><B>CONCLUSIONS: </B>Total wrist arthroplasty using this wrist prosthesis leads to favorable clinical outcomes regarding pain relief and retained range of wrist motion.<BR><B>METHODS: </B>Therapeutic IV.
