the articulation of the talus with the navicular. The movement which takes place in this joint is more extensive than that in the other tarsal joints, and consists of a sort of rotation by means of which the foot may be slightly flexed or extended, the sole being at the same time carried medially (inverted) or laterally (everted).
The Ligaments Connecting the Calcaneus and Navicular.Though the calcaneus and navicular do not directly articulate, they are connected by two ligaments: the calcaneonavicular part of the bifurcated, and the plantar calcaneonavicular.
The calcaneonavicular part of the bifurcated ligament is described on page 354.

The Plantar Calcaneonavicular Ligament (ligamentum calcaneonaviculare plantare; inferior or internal calcaneonavicular ligament; calcaneonavicular ligament) (Figs. 354, 358).The plantar calcaneonavicular ligament is a broad and thick band of fibers, which connects the anterior margin of the sustentaculum tali of the calcaneus to the plantar surface of the navicular. This ligament not only serves to connect the calcaneus and navicular, but supports the head of the talus, forming
