ABSTRACT
From 1983 to 1998, 16 cases of finger reconstruction with a free neurovascular wrap-around flap from the big toe were treated. Fourteen cases were successful, and two cases failed. The authors reviewed these cases on the average of about 38 months after surgery. Pinch power was 51 percent of the unaffected normal hand, and two-point discrimination was 7.6 mm. The mean resorption of the grafted bone was 13 percent in width and 9 percent in length. There were no complications such as fracture of the grafted bone, nonunion, and pulp dislodgement. This procedure provided length, stability, and adequate sensibility for a functional pinch and grasp. Sensory return to the wrap-around flap on the thumb was often greater than for the same area on the opposite foot. The donor site of the wrap-around flap was acceptable, both aesthetically and functionally, and allowed the wearing of open-toed shoes by young women. Finger reconstruction with a wrap-around flap from the big toe yielded excellent cosmetic and functional results in cases involving amputation at the level of the metacarpophalangeal joints or distal to it. In addition, this procedure was an excellent choice for treatment in cases involving avulsion injuries of the fingers and reconstruction of soft-tissue defects after tumor excision.
