Outcomes of the Sauve-Kapandji Procedure in Patients with Advanced Rheumatoid Arthritis

ABSTRACT

PURPOSE: We evaluated the clinical and radiographic outcomes of the Sauve-Kapandji procedure for the treatment of advanced rheumatoid arthritis. METHODS: Twenty-severn wrists in twenty-two patients were treated for advanced rheumatoid arthritis with Sauve-Kapandji procedure. Patients were evaluated in terms of wrist pain, bony union, instability of the ulnar proximal stump, ulnar stump pain, range of motion and other complications. Pain was evaluated using a visual analog scale. Radiographic evaluation included calculation of the carpal translation index to assess the extent of ulnar translation of the carpus. RESULTS: The average visual analogue scale score improved from 4+/-1.85 preoperatively to 0.78+/-0.91 at the last follow-up (p=0.003). Bone unions in distal radioulnar joint were obtained in all 22 patients, 27 wrists at mean 10.74 weeks (range, 6-28 weeks) after operation. The supination/pronation range of motion was changed from 55/50 degrees preoperatively to 79/73 degrees at postoperative 6 months follow up (p=0.32). The mean carpal translation index did not change after the operation. CONCLUSION: The Sauve-Kapandji procedure is a reliable methods of relieving pain, preserving range of motion (supination/pronation) and preventing ulnar translation of the carpus in managements of the severely destroyed distal radioulnar joints in rhematoid arthritis.
