The proximal articular surface (posterior surface) of navicular bone is the oval, concave, posterior area of the bone. It’s one of the six surfaces of the navicular bone, the other five being the plantar, dorsal, medial and lateral surfaces, and the distal articular surface.
The proximal articular surface of navicular bone articulates with the navicular articular surface of the talus, contributing to the formation of the talocalcaneonavicular joint.
