talocalcaneal

The posterior or talocalcaneal articulation is formed between the posterior calcaneal facet on the inferior surface of the talus, and the posterior facet on the superior surface of the calcaneus.

—The anterior talocalcaneal ligament extends from the front and lateral surface of the neck of the talus to the superior surface of the calcaneus.

It is, in fact, a portion of the united capsules of the talocalcaneonavicular and the talocalcaneal joints, and consists of two partially united layers of fibers, one belonging to the former and the other to the latter joint.

III. Syndesmology. 7e. Intertarsal Articulations 1918

It is an arthrodial joint, and the two bones are connected by an articular capsule and by anterior, posterior, lateral, medial, and interosseous talocalcaneal ligaments.

III. Syndesmology. 7e. Intertarsal Articulations 1918

—The interosseous talocalcaneal ligament forms the chief bond of union between the bones.

III. Syndesmology. 7e. Intertarsal Articulations 1918

—The posterior talocalcaneal ligament connects the lateral tubercle of the talus with the upper and medial part of the calcaneus; it is a short band, and its fibers radiate from their narrow attachment to the talus.

III. Syndesmology. 7e. Intertarsal Articulations 1918

—The lateral talocalcaneal ligament is a short, strong fasciculus, passing from the lateral surface of the talus, immediately beneath its fibular facet to the lateral surface of the calcaneus.

Coronal section through right talocrural and talocalcaneal joints.

—The medial talocalcaneal ligament connects the medial tubercle of the back of the talus with the back of the sustentaculum tali.

III. Syndesmology. 7e. Intertarsal Articulations 1918

—The articular capsule is imperfectly developed except posteriorly, where it is considerably thickened and forms, with a part of the capsule of the talocalcaneal joint, the strong interosseous ligament which fills in the canal formed by the opposing grooves on the calcaneus and talus, as above mentioned.
