[Rehabilitation of the first dorsal interosseous muscle by transfer of the extensor pollicis brevis tendon].
Weakness of the pinch grip between index finger and thumb, in ulnar nerve palsy, leads to severe loss of hand function. The first dorsal interosseous plays a major rôle as it abducts and flexes the index finger at its base and stabilizes the MP joint of this finger. Replacement of this muscle is therefore important. The authors report the results of eight clinical cases of replacement of the first dorsal interosseous by extensor pollicis brevis. They obtained good improvement of hand function, in terms of objective and subjective results, in all cases.
