European ]r~l.,~e Journal of buttery Summary. Seven large defects of the lower torso were closed with rectus abdominis musculocutaneous flaps: two large groin defects, three abdominal wall defects, and two open lateral pelvic wounds. Five of the flaps were inferiorly based and two superiorly based. The donor site was closed primarily unless a large skin paddle was taken, in which case the donor site was skin grafted. The central location, excellent blood supply (superior and inferior epigastric arteries plus abundant cutaneous perforators), and length and thickness of the rectus abdominis muscle make it a versatile flap for abdominal wall and lower torso defects.
