Seen from below. which a groove (sulcus calcanei) leads backwards and medially around the antero- medial border of the articular surface. When the calcaneus is placed in contact with the talus, this groove coincides with the sulcus on the plantar surface of the talus, and so forms a canal or tunnel (sinus tarsi) in which the strono- interosseous ligament which unites the two bones is lodged. To the front and medial side of this groove there is an elongated articular facet directed obliquely from behind forwards and laterally, and concave in the direction of its lono- axis. This is frequently divided into two smaller oval areas by an intermediate non- articular surface. Of these facets the posterior (facies articularis media) articulates with the middle calcanean facet on the plantar surface of the talus, whilst the anterior (facies articularis anterior) supports the plantar surface of the head of the talus (facies articularis calcanei anterior). The lateral side of the anterior extremity of the dorsal surface of the bone is rough, and to this is attached the orioin of the short extensor muscle of the toes. The plantar surface of the bone is slightly concave from before backwards, and convex from side to side. The plantar aspect of the tuberosity is provided with two tubercles, a medial (processus medialis tuberis calcanei) and a lateral (processus lateralis tuberis calcanei), of which the former is the larger. From this the short flexor of the toes and the abductor hallucis muscle arise, whilst from both tubercles 17a.
