Summary:. Unlike other body parts, the upper extremity has critical structures close to the skin, making soft tissue injuries more complex. These injuries can result from various causes, including trauma and necrotizing soft tissue infections, necessitating reconstruction. Historically, pedicled flaps from the groin and abdomen were commonly used for upper extremity reconstruction, but they had limitations, such as the need for flap division and debulking, patient discomfort, and stiffness. Free flap reconstruction has become the preferred method, but it still faces challenges like patient and facility issues, the absence of recipient vessels after injury, and multi-surface wounds. This case report describes a 67-year-old patient with a severe necrotizing soft tissue infection in the right upper extremity. After multiple debridement procedures, the patient underwent hand amputation and soft tissue coverage using an abdominal wall-based flap. The objectives of achieving stable soft tissue coverage while preserving maximal length of the upper extremity were successfully achieved, and the patient expressed satisfaction with the outcomes. Inadequate management of upper extremity wounds can lead to amputation and psychological distress. The reconstructive ladder is used to approach upper extremity soft tissue defects, with free tissue transfer being the standard for larger defects. However, abdominal flaps still have indications when free tissue transfer is not feasible or contraindicated. It is imperative that plastic surgeons have these techniques in their armamentarium to provide a service to the ever more complex patient with an upper extremity wound.
