Role of vascularized bone grafts in lower extremity osteomyelitis.

Abstract

Vascularized bone grafting seems to be a valuable reconstructive technique for the treatment of osteomyelitis with skeletal defects greater than 6 cm in length. Fibular osteocutaneous, composite rib, and iliac osteocutaneous flaps are the most commonly used vascularized bone grafts clinically. Vascularized bone can obliterate dead space, bridge large bone defects, enhance bone healing, resist infection by ensuring blood supply, allow early rehabilitation, and ensure better clinical outcomes in the treatment of lower extremity osteomyelitis. Success rates range from 80% to 95%. Complications of surgery include anastomosis failure, donor site problems, and fracture of the grafted bone.
