Acquired vertical talus due to burn contractures. A report of two cases.

A vertical talus is one feature of the rare congenital abnormality known as congenital convex pes valgus (Lamy and Weissman 1939), or rocker-foot (Hark 1950). Two cases of vertical talus deformity are described here associated with severe burn contractures. The position of the contractures suggests that the scarring is responsible for the deformities. If this is so, does the acquired abnormality throw any light on the mechanism of the congenital condition, or vice versa?
