Osteochondritis dissecans of the subtalar articular facet: an unusual diagnosis

Pediatric Radiology volume 35, pages 823–825 (2005)Cite this article

Abstract

Osteochondritis dissecans of the talus is classically characterized by an abnormality of the articular cartilage of the talar dome. We report a rare case of a lesion of the subtalar facet in a 10-year-old boy. The lesion was responsible for a painful ankle with secondary instability. The diagnosis was made using plain radiographs and CT, which showed a well-circumscribed osteochondral fragment demarcated from the adjacent bone by a radiolucent line. The clinical outcome was favourable after a 6-week period with a non-weight-bearing short-leg cast.
