          Abstract

          Avascular necrosis of the talus is a serious potential complication of clubfoot surgery. In the few cases described in the literature, the necrosis has involved the entire talus and resulted in progressive fragmentation and collapse. Serial postoperative radiographs of 96 idiopathic clubfeet in 70 patients are reviewed here to determine the incidence of avascular necrosis after McKay soft tissue release. Based on criteria in the literature for making the diagnosis, no cases of avascular necrosis were seen. Growth lines were observed in the cuboids and calcanei of all the feet during the follow-up period. Eight feet failed to develop growth lines in the talus during follow-up. Five of these feet showed flattening of the dome of the talus and three hypoplasia of the talar head and neck at the most recent follow-up. Absence of normal growth lines in the talus after operation seems to predict talar abnormalities.
