Related to subtalar joint: midtarsal joint

sub·ta·lar joint

[TA]
a plane synovial joint between the inferior surface of the talus and the posterior articular surface of the calcaneus. The term is also used clinically to refer to the compound joint formed by the talocalcaneal and anterior and middle talocalcaneal parts of the talocalcaneonavicular joints.

subtalar joint

the joint between the large posterior calcaneal facet on the inferior surface of the talus and the corresponding posterior talar facet on the superior surface of the calcaneus. It allows gliding and rotation, which are involved in inversion and eversion of the foot.

Synonym(s): talocalcaneal joint.

subtalar joint

partly synovial (anterior and posterior articulations) and partly syndesmotic (talocalcaneal ligament within sinus tarsi) trifaceted, saddle-shaped joint between inferior aspect of talus and superior aspect of calcaneum; permits triplanar movement (supination and pronation) of foot upon leg (see Table 1)
