Proximal femoral resection and Tensor Fascia Lata flap for recalcitrant trochanteric pressure ulcers.

Introduction: Trochanteric pressure ulcers (PrUs) are difficult to treat and are often complicated by infection spreading to the hip joint. We review three cases from India where proximal femoral resection and pedicled Tensor Fascia Lata (TFL) flapping was used in the management of infected deep trochanteric ulcers communicating to the hip joint.

Case presentation: Three patients had a total of four trochanteric PrUs communicating to the hip joint. Proximal femoral resection along with radical debridement of the pressure ulcer (PrU) was the first step in our surgical protocol. Serial debridements were performed to make the resulting cavity healthier and ready for the subsequent flap surgery. TFL flapping was done to cover the raw area of the PrU and the donor site was closed either primarily or with a split skin graft. All patients were males with AIS A spinal cord injury (SCI) and stage 4 PrUs in the trochanteric region. One patient had bilateral trochanteric ulcers. There was complete healing of all PrUs with improvement in wheelchair mobility, and general health.

Discussion: PrUs are a common complication of patients with SCI and are often considered one of the most neglected issues of health care delivery in India. Proximal femoral resection with pedicled TFL muscle flap is a versatile and reliable procedure for the coverage of recalcitrant trochanteric PrU with hip joint involvement. Minimal donor site morbidity occurs.
