Utility of the inferior gluteal vessels in free flap coverage of sacral wounds.

An improved technique for gaining access to the inferior gluteal vessels is presented. This method allows rapid isolation of these vessels, preservation of greater pedicle length, and improved access for the performance of microsurgery. The innervation and function of the gluteus maximus is also preserved. We believe the use of this technique makes the inferior gluteal vessels the receptor vessels of choice for microsurgical procedures in the sacral area. An illustrative patient is presented in whom these vessels were used for a combined serratus anterior-latissimus dorsi free muscle flap for sacral wound coverage.
