Coverage of lower extremity wounds, especially those in the distal leg, present challenges to the reconstructive surgeon. The present case illustrates a surgical technique utilizing a distally based reverse soleus muscle flap for coverage of an anterior leg wound deficit with exposed bone. The wound failed conservative wound care and was at risk of a below the knee amputation. The wound was first debrided to healthy bleeding tissue. The Truelok TL External Fixator was then applied for stabilization of the muscle flap. The medial portion of the soleus muscle was dissected with care to preserve its vascular supply and transposed to cover the wound defect. This was followed by utilization of the Integra Bi-Layer Matrix to control the vapor loss of the wound, act as a bacterial barrier, and provide a scaffold for cellular invasion and capillary growth. A wound VAC was applied to promote granular tissue formation. Following post-operative wound care, a split-thickness skin graft was later applied. The limb was salvaged and wound closure was achieved within three months. The patient began ambulating in a patella tendon bearing orthosis within four months. The reverse soleus muscle flap provides a viable option for ankle wound and anterior leg coverage, especially in medically frail patients. Due to a high degree of versatility, reliability, minimal donor site morbidity, less operating time, low cost and good functional gain; this procedure is highly suitable for the treatment of complex middle and lower leg defects. It should be considered in the reconstruction of soft tissue defects about the ankle, especially when the surgeon has exhausted all other conservative and surgical options.
