Distal partial gluteus maximus musculocutaneous V-Y flap: a simplified technique for reconstruction of ischial pressure sores

Abstract

Ischial pressure sores are mostly seen in wheelchair-bound patients and they have a high risk of recurrence due to a multitude of reasons compared with sacral and trochanteric ulcers. Various treatment modalities have been presented but high recurrence rates maintain its importance. Between 2009 and 2016, a total of 14 patients with spinal cord injuries were operated on for a total of 17 Shea stage IV ischial ulcers with the described technique. Demographic variables were recorded. Postoperative outcomes were categorized as early and late complications. A partial distal portion of gluteus maximus muscle (not the whole) was dissected and freed from the femoral insertion. The muscle was used as a carrier for the triangular flap lying above. The muscle was transposed medially and the triangular flap was advanced in a V-Y fashion to cover the defect. The follow-up periods ranged between 15 and 61 months. Among all the 14 patients, only one (7.1%) had a recurrence after 1 year postoperatively which needed an additional debridement and advancement of the previous flap. This patient had a non-recurrent period of 16 months after the second operative procedure. Wound dehiscence, as an early complication, was seen in one patient which healed secondarily. The distal partial gluteus maximus musculocutaneous V-Y flap is a simple and new approach with low complication rates for reconstruction of ischial pressure sores. Although there is still not an ideal flap for this challenge, the present technique could be a reliable option for the reconstructive armamentarium.Level of evidence: Level IV, therapeutic study.
