Repair of high-energy-induced tissue defects of the dorsal foot by free muscle transfer and skin graft.
Various alternative methods have been used for repair of extensive dorsal foot defects due to high-energy-induced injuries. The authors reconstructed such defects with free muscle transfers and skin grafts in 9 male patients (average age, 21.7 years) between the years 1995 and 1998. Patients (right foot, 5; left foot, 4) presented with injuries due to military rifle gunshot (N = 4), mine explosion (N = 2), high-voltage electricity (N = 2), and traffic accident (N = 1). The patient injured in a traffic accident was treated with skin grafting only, and experienced osteomyelitis and skin breakdown. The other 8 patients were injured acutely and were hospitalized within 3 weeks of injury. After serial debridement of necrotic tissues, surgery was performed at an average of 6 weeks postinjury. Metatarsal bone defects of 5 cm in 3 patients were repaired by iliac (N = 2) and fibular (N = 1) bone grafts. Free muscle latissimus dorsi (N = 4) and rectus abdominis (N = 5) flaps were transferred microsurgically. The transferred muscle flaps were covered with split-thickness skin grafts. Mean operation duration was 5 hours 12 minutes. All flaps survived. The average area of soft-tissue defect repaired was 93 cm2 (range, 36-231 cm2). Average follow-up was 25 months. No symptoms of osteomyelitis and skin breakdown were encountered in the 8 acutely injured patients. Monofilament sensory tests revealed diminished protective sensation in 5 patients and absence of protective sensation in 4 patients. Partial resorption of bone grafts occurred in 2 patients. Thinning of the flaps was performed by tangential excision in 2 patients whose muscle flaps did not diminish in thickness. All patients were able to wear normal shoes. The authors suggest the use of free muscle transfer in reconstructing extensive soft-tissue defects of the dorsal foot.
