Face articular talar média - Facies articularis talaris media
On the superior surface of the calcaneus, in front and to the medial side of the calcaneal sulcus is an elongated facet, concave from behind forward, and with its long axis directed forward and lateralward. This facet is frequently divided into two by a notch: of the two, the posterior, and larger is termed the middle talar articular surface; it is supported on a projecting process of bone, the sustentaculum tali, and articulates with the middle calcaneal facet on the under surface of the talus; the anterior talar articular surface is placed on the anterior part of the body, and articulates with the anterior calcaneal facet on the talus.
