We describe our experience with the use of an island gluteus maximus musculocutaneous flap (from its most inferior part) based on perforators from the inferior gluteal artery. The study is based on a series of 27 patients in whom treatment was carried out for 31 ischial pressure sores. Eight patients had postoperative complications in the form of dehiscence of the donor flap site and/or infection. Follow-up ranged from 6 to 32 months. During this period three patients developed recurrent sores which were treated with other flaps. We feel strongly that the use of this flap should be considered as a first choice in the treatment of the mild to moderate size ischial pressure sore. Its advantages include ease in elevation of the flap and the provision of a vascularized bulky flap which also spares the vascular pedicles of adjacent flaps for future use.
