In order to study the curative effect of vascularized bone graft in the treatment of avascular necrosis of talus, 24 patients were treated with vascularized bone grafts, in which 9 cases had received 1st cuneiform bone graft with a malleolaris anteriomedialis, 4 cases with the 1st cuneiform bone graft with the medial tarsal artery and 11 cases with vascularized cuboid bone graft with the lateral tarsal artery. All of the patients were followed up for 3-5.5 years. The clinical observation and X-ray examination showed that function of the ankle joint was completely or almost normal in 16 cases, and the bone repair was excellent. There was slight pain in the ankle joint in 4 cases. The efficiency rate of the treatment was 83.3%. It could be concluded that vascularized bone graft might be an effective method in the treatment of avascular necrosis of talus.
