The pectoralis major island flap for coverage in the upper extremity.

From July 1, 1978, to July 1, 1980, 26 patients required pedicle flap coverage for acute skin loss defects in the hand and upper extremity. Eighteen patients had groin or abdominal flap coverage, and the pectoralis major island flap (PMIF) was used in eight patients. The circumstances of injury were approximately the same in both groups, consisting of a gunshot wound or electrical injury in over half of the cases. The PMIF was selected more often in proximal and dorsal injuries of the forearm and wrist and in older patients. Two of 13 groin flaps sustained partial necrosis, but none of the abdominal or PMIF flaps necrosed. The principle advantages of the PMIF in these selected cases was fourfold: (1) an extremity placed in a less dependent, sling-like position, (2) mobility, (3) reliability, and (4) a complete inset into the defect. The chest wall donor site defect, however, must be given some consideration.
