Modified Sauvé-Kapandji procedure for rheumatoid wrists: A long-term study with a minimum follow-up of 5 years

AbstractObjectives. We performed a modified Sauve-Kapandji procedure for treating disorders of distal radioulnar joint in patients with rheumatoid arthritis (RA). This procedure involves resecting the distal part of the ulna, rotating the resected portion by 90° and fixating it with the distal part of the radius for shelf plasty. The purpose of this study was to examine the clinical and radiographic outcomes of this procedure with more than 5 years’ follow-up.Methods. We studied 32 wrists of 27 RA patients with the mean follow-up of 93.1 months after operation. Pain, grip strength and range of motion of the wrist were examined clinically, while two indices for evaluation of ulnar and palmar translation of the carpus, carpal translation index and palmar carpal subluxation ratio were calculated on radiographs.Results. The wrist pain reduced in all cases. Range of motion increased significantly regarding pronation and supination but decreased significantly regarding flexion. Change in grip power was not sign...
