A Successful Limb Salvage of an Electrical Burned Patient With Extensive Soft Tissue and Femoral Bone Necrosis.

Severe electrical injury presents a formidable therapeutic challenge for surgeons because of the requirement for complex soft tissue and bony reconstruction to restore functionality of the injured area. The authors report on the limb salvage procedure for a patient with extensive soft tissue and femoral bone necrosis from a high-voltage electrical burn. The right thigh and knee were burned, resulting in large areas of muscle necrosis and a long segment of distal femur exposure and necrosis. Complete debridement of the area resulted in a 20 × 35 cm soft tissue defect and an 18-cm long distal femoral bone defect. The wound was repaired through latissimus dorsi muscle transplantation and bony reconstruction using the sequential Ilizarov osteogenesis method. The injured limb was retained, and the functional recovery of the patient's leg was satisfactory. This experience indicates that the combination of flap transplantation and the Ilizarov osteogenesis method are good options for the treatment of large soft tissue and huge segmental bony defects.
