Successful replantation of an avulsed middle finger

In avulsion amputations of the digits, soft-tissue injuries are extensive and often require tendon, nerve, and vessel transfers or grafts. The functional results of such digital replantations are frequently less than ideal. Therefore, avulsion amputation of a single digit proximal to the insertion of the flexor digitorum superficialis has been a contraindication to replantation, because the anticipated poor functional result may interfere with overall hand function, and is not worth the sacrifice of a tendon, nerve, or vessel from another digit or transfer. The authors report a patient with avulsion amputation of the middle finger at the proximal interphalangeal joint. The digit was replanted successfully without any tissue transfers other than a radial digital artery from the ring finger. The functional results were good, and the authors believe that good functional and cosmetic results can be achieved in select patients with isolated digital avulsions, provided that an experienced hand microsurgeon and a skillful hand therapist are available for a compliant patient.
