[Coalition 06] Subtalar Joint on MRI: Anatomy Every Radiologist Must Master The subtalar joint is a complex articulation between the talus and calcaneus, best assessed with MRI for both normal anatomy and coalition-related pathology. Talocalcaneal articulations Posterior subtalar joint: concave talar facet with convex calcaneal facet, largest and best seen in coronal/sagittal planes. Talocalcaneonavicular joint: talar head with navicular, plus anterior and middle facets. Articular facets on MRI

The talus and calcaneus make up the two bones of the subtalar joint (STJ), otherwise known as the talo-calcaneal joint. The STJ consists of three articular facets, the posterior, middle and anterior facets. The two physiologic motions of the STJ are supination and pronation. During STJ supination, the talus glides posterior-superiorly on the posterior facet of the calcaneus. During STJ pronation, the talus glides anterior-inferiorly on the posterior facet of the calcaneus. The maximally pronated

This is a self-mobilization for the subtalar joint! The subtalar joint is formed where your heel bone, or the calcaneus, meets the talus, which is the ankle bone between your heel and your shin. The subtalar joint allows for us to move our heel out (eversion) and in (inversion). Inversion and eversion of the ankle are KEY for normal walking and running. With foot and ankle injuries, we often see the subtalar joint mobility is limited. This is a friendly self-mobilization technique you can try to
