[Opponens plastic surgery using the tendon of the m. extensor indicis].

For restoring the opposition of the thumb in lesions of the median nerve, numerous surgical procedures have been reported. In severe injuries with considerable scarring in the palmar wrist area the motor muscles of the forearm are useless and if the ulnar nerve is equally involved, opposition cannot be restored even with the Huber-Nicolaysen-Littler technique. In such cases we have recently come to carry out opponensplasties using the tendon of the extensor indicis with good success. The method is described and results are demonstrated.
