[Iliac transosseous transposition of rectus abdominis muscle flap to cover a sacral pressure sore].

The use of an inferiorly based rectus abdominis myocutaneous flap to cover a pelvic pressure sore offers a solution when the possibilities of other local flaps have been exhausted. For sacral pressure sores, the iliac bone is an obstacle for the transposition of this flap. In this case report, we describe how this obstacle can be overcome by creating a trans-osseous tunnel in the ala of the iliac bone through which the flap takes the most direct route to the recepient site.
