Radical excision and reconstruction of chronic tibial osteomyelitis with microvascular muscle flaps.

摘要

We report a series of 21 patients with chronic osteomyelitis of the tibia treated with microvascular muscle flap reconstruction. All patients underwent a radical bone and soft-tissue excision until healthy, well-bleeding tissue was exposed. Six patients required cancellous bone grafting. Latissimus dorsi was used in 14 patients, gracilis in 4, and rectus abdominis in 4. One gracilis flap was lost due to vessel thrombosis and was replaced with a rectus abdominis free flap. Average follow-up was 2.5 years. There was no evidence of clinical infection in 20 patients at follow-up; the bone had healed, the soft-tissue cover was stable, and the laboratory parameters were normal. Bone infection recurred in 1 patient, resulting in a below-knee amputation. The radical excision of infected bone and affected soft tissue and reconstruction with a well-vascularized large free-muscle flap is an excellent solution in most difficult chronically infected cases.
