The talonavicular joint is an articulation between the head of talus and the posterior aspect of the navicular bone. It is a synovial saddle joint.
The talonavicular joint is an important part of the transverse tarsal joint, also known as Chopart joint, which is the articulation between the calcaneus and talus (hindfoot) and the navicular and cuboid bones (midfoot).
Despite having a weak joint capsule, the talonavicular joint is reinforced by three main ligaments:
- Inferiorly by the plantar calcaneonavicular ligament,
- Laterally by the calcaneonavicular part of the bifurcate ligament (calcaneonavicular ligament),
- Superiorly by the (dorsal) talonavicular ligament.
