ANKLE

The ankle joint is a hinged synovial articulation between the talus and the distal tibia and the fibula. Inferiorly, the talus articulates with the calcaneus through three facets, joint by the cervical and interosseous talocalcaneal ligaments located in a cone-shaped region termed the sinus tarsi.

The Chopart joint represents the articulation between the talus and navicular and the calcaneus and cuboid bones. The navicular, in turn, articulates with the medial, middle, and lateral cuneiforms.

The stabilizing structures of the lateral ankle include the anterior talofibular ligament, which extends from the fibular to the talus in the transverse plane, the calcaneofibular ligament and posterior talofibular ligament.


At the medial aspect of the ankle, the deltoid ligament is found consisting of deep and superficial components.
