Abstract
A method of treatment of interphalangeal hyperflexion and metacarpophalangeal hyperextension of the thumb in combined low median-ulnar nerve palsy is described. The flexor pollicis longus tendon is divided longitudinally into 2 slips. One tendon strip is cut distally, extracted from the fibro-osseous canal, passed superficial to the tendon sheath, and attached to its previous insertion. An extensor indicis proprius opposition transfer was simultaneously performed. Eleven patients were monitored for 1 to 4 years after surgery. All results were positive, and there were no recurrences of either Froment's or Jeanne's sign.
