Transretroperitoneal Pedicled Omental Flap for Coverage of Traumatic Sacral Defect: A Case Report

The greater omentum is a reliable choice for salvage soft-tissue reconstruction. Benefits include consistent anatomy, long pedicle length, and a high concentration of lymphatic tissue that is resistant to infection. We report the case of a 46-year-old man with a complex traumatic sacral wound resulting in severe limitation of reconstructive options. A pedicled greater omentum flap was transposed through the retroperitoneum via the lumbosacral triangle, resulting in durable soft-tissue coverage.
