Bipartite Medial Cuneiform and Calcaneo-Navicular Coalition in a Single Individual

“…A calcaneo-navicular coalition is a more common anatomical variant in which there is congenital failure of differentiation of the ossific nuclei of the calcaneum and navicular [13]. The true incidence of tarsal coalitions is unknown as many are asymptomatic, however it is often quoted at 1% with calcaneo-navicular coalitions accounting for 71.4-77.2% of these [14][15]. No cases of a bipartite medial cuneiform alongside a calcaneonavicular coalition have been described in the literature.…”
