The gluteus maximus island musculocutaneous flap has been described using a variety of designs. We employ an island whose long axis is directed toward the pressure sore, minimizing tension in wound closure. Skin overlying the greater trochanter is avoided. Previously undermined skin can be included in the flap. Fifty patients with ischial or sacral pressure sores have been managed by this technique. Superficial dehiscence occurred in 13 percent of patients, and deep dehiscence occurred in 10 percent. The dehiscence closed spontaneously in all but one patient. Forty-nine of the 50 patients experienced complete wound healing at the pressure sore site. The patients have been observed for an average of 20 months (range 3 to 38 months), with one recurrent pressure sore seen at 28 months postoperatively. The gluteus maximus musculocutaneous island flap has proven to be both reliable in healing and durable over the observed interval.
