Although the gluteal V-Y advancement flap has been recognized as the most reliable method for management of sacral pressure ulcers, its limited mobility has been a challenging problem. The authors present a new modification of the V-Y advancement flap to overcome the problem. After débridement, a large triangle is designed to create a V-Yadvancement flap on the unilateral buttock and the medial half is elevated as a fasciocutaneous flap, preserving the distal perforators in the muscular attachment. Then an arc-shaped incision is made in the gluteus maximus muscle along with the lateral edge of the triangular flap. The split muscle is elevated at a depth above the deeper fascia until sufficient advancement of the flap is obtained. This full-thickness elevation of the gluteus maximus muscle from the distal (lateral) side avoids the impairment of perforators or their mother vessels and achieves great advancement. Thirty-one patients with sacral pressure defects larger than 8 cm in diameter were treated using this surgical procedure. Overall, 93.5 percent of the flaps (29 of 31) healed primarily. The largest defect that was closed with a unilateral flap was 16 cm in diameter. The present technique accomplishes remarkable excursion of the unilateral V-Y fasciocutaneous flap, with high flap reliability and preservation of the contralateral buttock as well as gluteus maximus muscle function.

Despite a wide variety of flap options, ischial ulcers remain the most difficult pressure ulcers to treat. This article describes the authors' successful surgical procedure for coverage of ischial ulcers using adipofascial turnover flaps combined with a local fasciocutaneous flap. After debridement, the adipofascial flaps are harvested both cephalad and caudal to the defect. The flaps are then turned over to cover the exposed bone in a manner so as to overlap the two flaps. A local fasciocutaneous flap (Limberg flap) is applied to the raw surface of the turnover flaps. Twenty-two patients with ischial ulcers were treated using this surgical procedure. Overall, 86.4 percent of the flaps (19 of 22) healed primarily. Triple coverage with the combination of double adipofascial turnover flaps and a local fasciocutaneous flap allows for an easily performed and minimally invasive procedure, preservation of future flap options, and a soft-tissue supply sufficient for covering the prominence and bony prominence and filling dead space. This technique provides successful soft-tissue reconstruction for minor to moderate-size ischial pressure ulcers.
