Outcome of the Sauvé–Kapandji procedure for distal radioulnar joint disorder with rheumatoid arthritis or osteoarthritis: Results of one-year follow-up

Abstract

Objectives: We performed the Sauvé–Kapandji procedure for treating disorders of the distal radioulnar joint (DRUJ) in patients with rheumatoid arthritis (RA) or osteoarthritis (OA). This study aimed to compare and clarify the results of the SK procedure between RA and OA patients. We report the one-year follow-up results of patients who underwent the SK procedure to correct the DRUJ disorder caused by RA or OA.

Methods: The study included 22 wrists of 19 patients with RA and 10 wrists of nine patients with OA. Pain, grip strength and range of motion of the wrist were examined clinically. For the evaluation of the stability of the carpus, ulnar stump and bone union, parameters were measured using radiographs. Shortened disabilities of the arm, shoulder and hand questionnaire (QuickDASH) was used for functional evaluation.

Results: Wrist pain reduced in all cases, and bone union was achieved in all wrists. The QuickDASH score significantly improved in both patients with RA and OA. In patients with RA, the range of motion increased significantly with regard to supination but decreased significantly with regard to palmar flexion. Carpal alignment and ulnar stump stability were maintained well at one-year follow-up.

Conclusion: The Sauvé–Kapandji procedure for treating disorders of the distal radioulnar joint DRUJ showed good results clinically and radiographically, irrespective of RA or OA.
