The inferiorly based rectus abdominis myocutaneous flap for reconstruction of recurrent pressure sores

Eight neurologically impaired patients underwent reconstruction of chronic perineal and ischial pressure sores utilizing an inferiorly based rectus abdominis myocutaneous flap. Other local and regional flap options had been previously used or were not feasible. In six patients, healing was uncomplicated. One patient required local debridement and flap readvancement. The second involved minor separation of a suture line and healed by secondary intention. All donor sites were closed directly and healed by primary intention. There was no evidence of hernia formation, and no functional deficit was detected from removal of the rectus muscle in any of the patients. In conclusion, it was felt that the inferiorly based rectus abdominis myocutaneous flap should be considered a reconstructive option in dealing with perineal and ischial pressure sores. Furthermore, for reasons discussed, we found distinct advantages to using this flap in spinal cord injury patients.
