We retrospectively compared wrist arthrodesis using the Mannerfelt technique in 19 or an AO-plate in 23 patients with long-standing rheumatoid arthritis. The mean follow-up was for 76 months. Compared with the Mannerfelt fusion group, patients in the AO-plate group reported greater satisfaction with their wrist function (74% vs 37%, p = 0.015). Complications were reported in six wrists in the AO-plate group and two wrists in the Mannerfelt fusion group (p = 0.258). At final follow-up, 95% of patients (41) reported either no pain or only mild pain. There was improvement in flexion of the finger joints in both groups but no significant improvement in the extension lag in either group. Both methods relieve pain and improve function. Overall, the activities of daily living scores and the patients subjective assessment of outcome tended to be higher in the AO-plate group than in the Mannerfelt fusion group, although the difference was not statistically significant. Similarly, although more postoperative complications occurred in the AO-plate group, the difference between the two groups was not statistically significant.
