The talus ranks as the second largest tarsal bone with unique anatomic features and serves an important role in mobility of the foot and ankle as it is the osseous link between the leg and the foot. The anatomy of the talus is quite complex with three separate articulations with distinct features including the subtalar joint with its three faces. The talus divides into a head, neck, and body. Not surprisingly the covering of approximately two-thirds of the surface is articular cartilage, and there are few muscle or tendon attachments. The convex talar head is covered with hyaline cartilage articulating with the navicular at the anterior/distal aspect linking the ankle and midfoot.  The talar head also articulates with the calcaneus via the anterior facet at its inferior margin (anterior portion of the subtalar joint). The talar body articulates with the calcaneus inferiorly using the middle (anteromedial) and posterior (posterolateral) facets. The posterior facet is the larger of the two making up the posterior subtalar joint while the middle facet articulates with the sustentaculum tali (medial process from the calcaneus). Incidentally, it is the middle facets of the subtalar joint which are most commonly involved in talocalcaneal coalition accounting for 45% of tarsal coalitions. The superior aspect of the body, the talar dome or trochlea, articulates with the tibia at the tibiotalar joint. The neck is the portion of the talus which joins the head and body, without an articular surface or cartilage. The sinus tarsi and tarsal canal lie along the inferior margin of the neck. The posterior process of the body is composed of the medial and lateral tubercles. The flexor hallucis longus tendon runs between these two tubercles. A Stieda process is an anatomic variant defined as elongation of the lateral tubercle. The os trigonum is another normal variant due to non-fusion of the lateral tubercle ossification center. Both of these normal variants can be involved in pathology ranging from fracture to os trigonum syndrome. The lateral process extends from the lateral aspect of the body of the talus. This process articulates with the fibula superiorly and forms the anterolateral portion of the posterior facet of the posterior subtalar joint. Fracture of the lateral process has been termed “snowboarder’s fracture” and is commonly missed on initial radiographs. Evaluation of the lateral process of the talus is best on AP radiographs of the ankle. Vascular supply to the talus arises from three arteries: posterior tibial, dorsalis pedis and perforating peroneal arteries. The blood supply is predominately extraosseous because of the extensive articular cartilage coverage and is therefore easily disrupted in the setting of displaced fractures or dislocation leading to avascular necrosis or osteonecrosis.
