Lower extremity salvage using a free flap associated with the Ilizarov method in patients with massive combat injuries.

Nine patients with massive combat injuries of the lower extremities were treated with Ilizarov bone transport in conjunction with free muscle flap coverage. In 4 patients soft-tissue coverage was applied first, and distraction osteogenesis was initiated 4 to 6 weeks later. In 3 patients both methods were applied simultaneously, and in 2 patients soft-tissue coverage occurred after distraction. The bones healed well, and all flaps survived. The segmental defects ranged from 8 to 16.5 cm in greatest dimension. The total disability time from initial injury ranged from 16 to 25.5 months. In all patients, full union of the tibia was achieved, and no osteomyelitis occurred. However, in 2 patients the applied flap became depressed, necessitating another flap operation. Despite late treatment in all 9 patients, successful results were obtained. Maintaining the original length of the tibia and providing timely, definitive treatment offer the best outcome for repair of massive injuries of the lower extremities. The Ilizarov transport method, used in combination with muscle flap coverage, represents an effective therapy for repair of massive injury of the lower extremities.
