Translocation of tibial bone flap pedicled with descending branches of supramalleolar artery for treatment of avascular necrosis of talus
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.
