A Rare Case of Symptomatic Planovalgus Foot with Triple Coalition

Tarsal coalitions in the general population are low, possibly due to the asymptomatic nature. In the symptomatic group, however, the presentation is usually during adolescence or early adulthood. The occurrence of a triple tarsal coalition is extremely rare, especially if not associated with a syndrome.

We report a case that has the unique configuration of talocalcaneal, talonavicular, and calcaneocuboid coalitions with a planovalgus foot. We review the available literature on this rare occurrence and outline our management in this case to achieve a plantigrade, painless functional foot.

Symptomatic triple coalition planovlagoid cases, require a surgical corrective procedure in order to achieve a plantigrade foot.
