title: The island pedicled anterolateral thigh (pALT) flap via the lateral subcutaneous tunnel for recurrent ischial ulcers.
abstract: Chronic recurrent ischial sores are an important cause of morbidity in paraplegics and geriatric patients. Compared to sacral and trochanteric ulcers, ischial sores are the most difficult to treat, with a low success rate following conservative therapy and a high recurrence rate after surgical treatment. We report the use of the pedicled anterolateral thigh (pALT) flap for reconstruction of a chronic ischial sore. The free ALT flap has an established role in reconstruction in the head and neck and extremities. However, there are few reports concerning its clinical applications for regional reconstruction. As a pedicled flap, it has been used in the primary reconstruction of the perineum, groin, anterior abdominal wall, thigh and ischium. We present the first reported case of a paraplegic man with a recurrent ischial sore treated successfully with an island pALT flap inset via a lateral subcutaneous approach. We discuss the indications and its role as a simple and reliable secondary reconstructive option in the treatment of recurrent ischial ulcers after first-line loco-regional surgical options have been exhausted.
