We describe a modification of the biceps femoris myocutaneous flap for reconstruction of ischial pressure ulcer defects. In this modification, all neural and vascular pedicles are preserved and the flap is advanced into the ischial defect rather than transposed as described in the literature. With this method, no transferred tissue is lost. Besides ensuring good tissue survival, the flap preserves a maximum number of reconstructive options in the event of ischial pressure ulcer recurrence. These advantages make the biceps femoris myocutaneous advancement flap our first choice for reconstruction of ischial pressure ulcer defects.
