Tarsal coalition is an abnormal connection between adjacent bones in the foot. It typically presents in late childhood or adolescence as a painful, rigid flatfoot. Calcaneonavicular and talocalcaneal coalitions are the most common types. If symptomatic, surgical treatment of the coalition is often necessary. Surgical treatment involves resection of the tarsal coalition with interpositional graft to prevent recurrence.
