title: Multiple unilateral tarsal coalitions in a nonsyndromic patient.
abstract: Tarsal coalition is relatively frequent, with an estimated prevalence of 1-2%. Coalitions are most commonly talocalcaneal or calcaneonavicular, accounting for 90% of cases. While it is well known that bilateral tarsal coalitions can occur in up to 50% of cases, the presence of multiple coalitions in the same foot is less well described. In this report, we present a case of talocalcaneal and calcaneonavicular coalitions occurring in the same foot and briefly review the relevant literature.
