[Correction of post-traumatic adduction insufficiency of the small finger by transposition of the tendon of the extensor indicis muscle].

The m. interosseus palmaris III adducts the small finger. Injuries of this muscle and lesions of the ulnar nerve lead to the small finger assuming an abducted posture. Tendon transposition of the extensor indicis to correct the abducted small finger in patients with injuries and ulnar nerve dysfunction is described.
