From left to right: Fracture of the neck, body and posterior process of the talus. The talus bone lacks a good blood supply. Because of this, healing a broken talus can take longer than most other bones. One with a broken talus may not be able to walk for many months without crutches and will further wear a walking cast or boot of some kind ...
The anterior talocalcaneal ligament (or anterior interosseous ligament) attaches at the neck of the talus on the front and lateral surfaces to the superior calcaneus. The short band of the posterior talocalcaneal ligament extends from the lateral tubercle of the talus to the upper medial calcaneus.
The anterior talocalcaneal ligament (anterior calcaneo-astragaloid ligament or anterior interosseous ligament) is a ligament in the foot.. The anterior talocalcaneal ligament extends from the front and lateral surface of the neck of the talus to the sinus tarsi of the calcaneus.
As its shape suggests, this joint is a synovial ball-and-socket joint. [1] It is composed of three articular surfaces: The articulation between the medial talar articular surface on the sustentaculum tali of the superior calcaneus and the corresponding medial facet found inferiorly on the talus neck [2]
Between these superior articulations and the equivalents on the talus is the tarsal sinus (a canal occupied by the interosseous talocalcaneal ligament). [citation needed] At the upper and forepart of the medial surface of the calcaneus, below the middle talar facet, there is a horizontal eminence, the talar shelf (also sustentaculum tali). [2]
It passes from the anterior margin of the fibular malleolus, passing anteromedially to insert at the lateral aspect of the talus at the talar neck , in front of its lateral articular facet. It is one of the lateral ligaments of the ankle and prevents the foot from sliding forward in relation to the shin.
The posterior talofibular ligament runs horizontally between the neck of the talus and the medial side of lateral malleolus calcaneofibular ligament; The calcaneofibular ligament is attached on the posteromedial side of lateral malleolus and descends posteroinferiorly below to a lateral side of the calcaneus.
The interosseous talocalcaneal ligament forms the chief bond of union between the talus and calcaneus.. It is 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.
