One-stage repair of compound leg defects with free, revascularized flaps of groin skin and iliac bone

Abstract

The successful revascularized free transfer of a composite flap of groin skin with attached iliac bone is presented in two patients. The findings in the preliminary dissections and injection studies in cadavers are discussed, and the superficial circumflex iliac system is recommended as a stem for free flaps of groin skin and iliac bone. If iliac bone alone is required for a revascularized graft, then the deep circumflex iliac system would seem suitable for the stem. Further clinical cases are necessary to determine the indications for this procedure, and patients should be carefully selected. The need for preoperative preparation and planning on a sound anatomical background is emphasized, and preoperative angiography seems advisable. The ability to sew small vessels together reliably is one thing: the when and where is another.
