Description
The subtalar joint refers to the articulation between the posterior calcaneal articular facet of the talus and the posterior talar articular facet of the calcaneus. This joint is a modified multiaxial joint and plays a role in movements such as inversion and eversion. Additionally, the subtalar joint is a synovial joint, where the posterior concave facet of the talus receives the convex posterior facet of the calcaneus.
The subtalar joint is supported by a fibrous capsule, and the lateral, medial, interosseous, and posterior talocalcaneal ligaments.
