目的　探讨胫前动脉踝上支降支蒂胫骨远端骨瓣移位治疗距骨缺血性坏死的临床效果。方法    2010年3月～2013年12月收治8例距骨创伤性缺血坏死患者，均采用胫前动脉踝上支降支蒂胫骨远端骨瓣移位治疗，术后石膏托固定踝关节4周。 结果　随访6个月~24个月，平均12个月。8例患者术后均获满意愈合，最终随访检查踝关节功能按Kenwight疗效标准评估，其中优6例，良2例。  结论    该骨瓣血管恒定, 血供丰富,手术操作简便，是治疗距骨缺血坏死的较理想方法。

Objective   To investigate the value of clinical application of  translocation of the tibial bone flap pedicled with vascular pedicledescending branches of supramalleolar artery descending branches for treatment of avascular necrosis of talus.   Methods    8 patients with traumatic ischemic necrosis of talus from March 2010 to December 2013 were treated by translocation of thetibial bone flap pedicled with vascular pedicled with descending branches of supramalleolar artery , and ankle joint was immobilized with plaster slab for 4 weeks after operation.   Results    The following-up ranged from 6 to 24 months, with an average of 12 months. Ankle joint function in the final following-up wasassessed according to kenwight curative effect standard: 6 cases were excellent, 2 cases good.    Conclusion    This bone flap has the advantages of constant vessels, abundant blood supply and the simple operation process, which is an effective method to treat avascular necrosis of talus.
