Tibiocalcaneal fusion for avascular necrosis of the talus.

Between 1994 and 1999, we treated six patients with avascular necrosis of the talus by excision of the necrotic body of the talus and tibiocalcaneal fusion using an Ilizarov frame. This was combined with corticotomy and a lengthening procedure. Shortening was corrected in all patients except two, who were over 60 years of age. All patients had previous operations which had failed. All achieved solid bony fusion, with five out of six having either a good or an excellent result. We conclude that this is an effective reconstructive technique which gives a good functional result.
