Navicular bone articulates with the head of talus proximally and the three cuneiforms distally. Proximal surface has single facet for the head of talus. Medial surface is important as it presents the tuberosity. Facets for all the cuneiforms are triangular. The apex of the facet for the medial cuneifom facet is directed medially and the apices of other two are directed down-wards. Tuberosity of the navicular gives insertion to the tibialis posterior muscle and the groove on the lateral side of the tuberosity gives passage to the rest of the tendon of the tibialis posterior.
