Shortening osteotomy for treatment of metacarpophalangeal joint deformity.
The results of a new subcapital shortening osteotomy for correction of metacarpophalangeal joint deformity in patients with rheumatoid arthritis of the hands are presented. Seven patients (16 joints) were followed up for a mean of 33.5 months. The mean shortening of the metacarpal bone was 4.6 mm (range, 4-8 mm), and seven joints had additional intrinsic release. Only four (25%) joints held the correction of the deformity; all other joints had recurrence of palmar subluxation with or without additional ulnar drift. The range of motion of the joints with preserved correction after surgery was 80 degrees compared with 28 degrees of the joints with recurrent deformity. The possible mechanism of failure was analyzed. The results of the current series suggest that subcapital shortening osteotomy may not be indicated for treatment of severe metacarpophalangeal joint deformity in patients with rheumatoid arthritis.
