Dorsal capsulodesis for scapholunate instability--effect on patient disability and wrist pain

Twenty cases of scapho-lunate instability have been reviewed, to determine the effect of dorsal capsulodesis on disability and wrist pain. The average follow-up was 41 (range 13-63) months. There was a significant improvement in the pre-operative Patient Rated Wrist Evaluation score from 108 (range 18-150) to a postoperative score of 60 (range 0-132). All wrist movements and grip strength were reduced postoperatively but only the reductions in flexion and radial deviation were statistically significant. Seventeen (85%) patients were satisfied with the operation. One patient remained unemployed after surgery. Five patients returned to their normal jobs. This study shows that dorsal capsulodesis should remain an important option in the treatment of scapholunate instability.
