Applications of the posterior thigh flap.

As our population ages and spinal cord injuries continue at their present rate due to motor vehicle accidents and handgun injuries, the development of pressure sores will most likely increase in frequency. The three major populations at risk to develop pressure sores include the elderly, long-term hospital patients, and neurologically impaired patients. the posterior thigh flap evolved during our experience with the lower extremity muscle flaps. We have used 22 posterior thigh flaps in 21 patients. We have found that it is a reliable flap with a dependable blood supply that can be used in the soft tissue coverage of trochanteric, ischial, and some sacral wounds. In addition, the posterior thigh flap can be used as a pedicled flap in the management of heel and foot wounds. In this review, the anatomy and application of the posterior thigh flap are elaborated.
