Treatment of pelvic defect and infection with endoprosthesis exposure by topical negative pressure and irrigation with myocutaneous flap.

The treatment of wound complications and deep infection after hemipelvectomy is challenging. We describe a 17-year-old woman with Ewing sarcoma in the pelvis who underwent hemipelvectomy and reconstruction with an artificial hip joint and bone cement. After the operation, skin necrosis and deep infection with methicillin-resistant Staphylococcus aureus (MRSA) were observed. Debridement resulted in exposure of the artificial joint and bone cement. Topical negative pressure (TNP) and irrigation successfully eradicated the infection. The skin and soft-tissue defect was subsequently reconstructed using a combination of free latissimus dorsi myocutaneous flap and serratus anterior muscle flap. To our knowledge, this is the first described case of combined TNP and irrigation with myocutaneous flap for the treatment of pelvic infection and skin and soft-tissue defect with endoprosthesis exposure.
