Repair of a huge defect of the gluteal region by rotation of a combined tensor fasciae latae-sartorius myocutaneous flap.

Abstract

Although the tensor fasciae latae myocutaneous flap is convenient for covering some defects in the gluteal region, it is not suitable to repair a huge defect because of its limited area. Based on the close relationship of the sartorius and the tensor fasciae latae at their origins and blood supply, the authors designed a myocutaneous flap containing both the tensor fasciae latae and the sartorius muscles and their skin territories with an area exceeding 800 cm2. Two successfully repaired patients are reported. The flaps provide normal sensitivity. The vascular pedicle has a reliable anatomy, being easily dissected, and averages 4.6 to 5.8 cm in length. Both muscles are expendable. There is little functional difficulty for hip joint after the operation.
