带蒂骨瓣移位术治疗距骨缺血性坏死

TREATMENT OF AVASCULAR NECROSIS OF TALUS WITH VASCULARIZED BONE GRAFT

为探讨治疗距骨缺血性坏死的有效方法，采用带蒂骨瓣移位术治疗距骨缺血性坏死２４例，９例采用内踝前动脉蒂第１楔骨瓣，４例采用跗内侧动脉蒂第１楔骨瓣，１１例采用跗外侧动脉蒂骰骨瓣。术后随访３年～５年６个月，优１６例，良４例，差４例，有效率为８３．３％。认为。

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 clincal 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.
