A new musculocutaneous island flap from the distal thigh for recurrent ischial and perineal pressure sores.
In the paraplegic patient who has had previous surgeries for pressure sores, local tissue is frequently unavailable for further use. The posterolateral aspect of the thigh, however, is almost always available and provides an excellent reconstructive alternative for this difficult problem. In 1983, Baek described the skin territory supplied by the third perforator of the profunda femoris artery. A musculocutaneous flap can be raised consisting of the same skin territory and a portion of the biceps femoris muscle (short head) through which the third perforator courses. In addition, the distal part of the vastus lateralis muscle, which is supplied by a muscular branch of the same perforator, can be included in the flap. The flap is elevated as an island based on the profunda femoris artery and accompanying venae comitantes. A substantial soft-tissue mass can be transposed easily to the perineum. Standard latex injection techniques were used in 12 fresh cadaver dissections prior to use of this flap in 16 clinical cases. Selective india ink injections into the third perforator of the profunda femoris artery in 6 cadavers confirmed the perfusion of the overlying skin territory. Recurrent ischial and perineal wounds were closed successfully with this musculocutaneous flap in all 16 clinical cases.
