[Surgical treatment of calcaneus-navicular synostosis]

We resected eight calcaneus-navicular bars in six children. The average age at the surgery was fifteen years, and the average follow up period was four years. In all cases the extensor digitorum brevis was interposed into the gap created by an excision of the bar. On the follow up three feet were painfree and four were occasionally painful. In one case a coalition recurred, and the pain did not improve. The ankle range of motion was normal in all cases, whereas the subtalar motion was limited in three feet, and normal in the remaining five.
