Clinical and radiological manifestations of the rheumatoid wrist after the Sauvé-Kapandji procedure.
A retrospective study was performed to investigate the clinical and radiological results of the Sauvé-Kapandji (S-K) procedure for the rheumatoid wrist. One hundred and eight rheumatoid wrists in 98 patients were operated on in our institute from 1992 to 2000, and in 82 wrists we used the S-K procedure. In other cases, synovectomy alone was performed on 16 wrists, and partial and total arthrodeses were performed concurrently on 5 wrists each. Carpal bones and/or radiocarpal joints in which the union could not be assessed radiologically were found in 49 wrists (59.8%) after the S-K procedure, and among them there was definite non-fusion of the carpal bone and radiocarpal joints in 29 wrists (35.4%). However, definite fusion of carpal bones and/or radiocarpal joints was found in 33 wrists (40.2%). The formation of carpal bones and partial radiocarpal fusion with some mobility was detected in some cases. Therefore, the S-K procedure may stabilize the carpus in the rheumatoid wrist to some extent while maintaining a functionally important range of motion and relieving pain. However, it does not stop the disease process and cannot reestablish or maintain carpal height. We concluded that the S-K procedure is the treatment of choice for the rheumatoid wrist, and if the wrist is unstable, as seen with arthritis mutilans, we then perform either radio-lunate partial arthrodesis or total wrist arthrodesis.
