[Progress of vascularized bone grafting for the treatment of avascular osteonecrosis of the femoral head].
Avascular osteonecrosis of the femoral head is a common disease in orthopedic clinics. If the diagnosis can be made before collapse of the femoral head, the hip joint may probably be preserved by means of core decompression with or without bone grafting, osteotomies, as well as nonvascularized or vascularized bone grafting. Local pedicled bone grafts and free vascularized bone grafts can transfer the vascularized bone grafts into the necrotic area of the femoral head, which not only can replace necrotic bone with healthy bone, but also establish a new source of blood supply to the femoral head. The success rate in patients with different stages of osteonecrosis of femoral head was 80% at 5 years follow up. Free vascularized bone grafting for the treatment of avascular osteonecrosis of the femoral head can obtain a higher success rate.
