Dual-Plane Gluteal Myocutaneous Flap for Reconstruction of Ischial Tuberosity Pressure Wounds.

Purpose: Ischial tuberosity pressure wounds are the most common type of pressure wound and contribute to a large percentage of the total cost of surgical and nonsurgical management of pressure wounds. Gluteal myocutaneous and fascocutaneous flaps are well-documented methods of coverage for ischial pressure wounds. This study aimed to describe results using a novel dual-plane gluteal myocutaneous flap technique for reconstruction of ischial tuberosity pressure wounds.
Methods: A retrospective chart review was performed of all patients who underwent dual-plane gluteus maximus myocutaneous flap reconstruction for ischial tuberosity pressure wounds performed by a single surgeon from 2012 to 2018. Patient demographic, clinical, and operative characteristics were reviewed. Outcomes were assessed by analyzing complication rates including recurrence, need for revision surgery, dehiscence, necrosis, wound infection, seroma, and hematoma.
Results: Eight dual-plane gluteus maximus myocutaneous flaps were performed for reconstruction of ischial tuberosity pressure wounds in 7 male patients with a mean age of 49.1 ± 14.9 years (mean ± SD) and mean body mass index of 26.7 ± 6.4 kg/m. All patients were nonambulatory secondary to spinal cord injury or congenital neurological disease. Two patients (28.6%) were diabetic, and 1 patient (14.3%) was an active smoker. The mean defect size after debridement of ischial pressure wounds was 60.7 ± 29.4 cm. After a mean follow-up of 16.4 months, partial wound dehiscence occurred in 1 patient (14.3%) and was managed with local wound care only. Infection and recurrence occurred in another patient (14.3%) and required revision surgery.
Conclusions: The dual-plane gluteal myocutaneous flap is an effective method for reconstruction of ischial tuberosity pressure wounds. Partially elevating the cutaneous layer off the gluteus maximus muscle allows for greater mobility and rotation of the muscle flap into the ischial pressure wound defect and closure of the flap and donor site with the cutaneous layer.
