Treatment of congenital convex pes valgus with navicular excision and subtalar arthroereisis: a case study

This article presents a case study of a 4-year-old female with a delayed diagnosis of congenital convex pes valgus. The severe soft-tissue contractures and osseous abnormalities in this case necessitated excision of the navicular and subtalar arthroereisis in addition to standard soft-tissue releases in order to achieve and maintain adequate reduction. A review of the literature and a discussion of these adjunctive techniques is provided to examine the concepts relevant to treatment of this condition.
