The talocalcaneonavicular joint (latin:articulatio talocalcaneonavicularis) is an articulation in the foot between the navicular, talus and calcaneus bones.
The articular surfaces of the talocalcaneonavicular joint are:
The bones of the talocalcaneonavicular joint are bounded by a fibrous capsule and the following ligaments: the talonavicular and plantar calcaneonavicular ligaments, and the calcaneonavicular part of the bifurcate ligament.
The talonavicular ligament stretches between the posterior surfaces of the neck of the talus and the navicular bone.
The plantar calcaneonavicular ligament is between the anterior margin of the sustentaculum tali and the plantar surface of the navicular.
The talocalcaneonavicular joint permits pronation and supination of the foot.
