Correction of neglected vertical talus deformity in an adult.

Congenital vertical talus is an uncommon foot deformity that is characterised by a fixed dorsal dislocation of the navicular on the talar head and neck. Left untreated, a congenital vertical talus causes significant long-term disability. We present a case of neglected vertical talus in a middle-aged woman who was successfully treated with resection of the talar head and tendon transfers.
