The rectus abdominis free flap as an emergency procedure in extensive upper extremity soft-tissue defects.

Abstract

Stable wound coverage after extensive soft-tissue loss of the upper extremity remains a difficult problem in the management of large defects of the upper limb. To prevent further tissue loss owing to infection or inadequate cover when important structures such as vessels, tendons, nerves, joints, and bones are exposed, various free flaps have been introduced into the therapeutic armamentarium of acute plastic surgical management options. Emergency or delayed early reconstruction has been proposed to prevent chronic infection and further tissue loss. We report a series of 12 emergency and delayed early reconstructions of the forearm, wrist, carpus, metacarpus, and hand using the free rectus abdominis muscle flap with split-skin coverage, demonstrating the versatility of this flap within this special context. Emergency free rectus muscle flap transfer is safe, technically easy, and expandable.
