Restoration of thumb-index pinch by a double tendon transfer following ulnar nerve paralysis.
Repair of ulnar nerve lesions by suture or grafts often gives good results, but in some cases there persists a long-term isolated paralysis of the muscles of the first web space. There is certain to be a resulting loss of function from loss of the thumb-index pinch which can be corrected by tendon transfers. In 11 cases the authors have used two tendon transfers: the short extensor of the thumb to re-establish the function of the first dorsal interosseous muscle, and the extensor indicis proprius to improve adduction. In every case there was notable improvement in the function of the hand.
