Talonavicular joint

The talonavicular joint is an important part of the Chopart joint between the talus of the hindfoot and the navicular of the midfoot.

Gross anatomy

The talonavicular joint primarily consists of the articulation between the head of the talus and the concavity produced by the posterior aspect of the navicular. This articulation is facilitated by the talonavicular ligament, a broad, thin band that covered by the extensor tendons, and the plantar calcaneonavicular (spring) ligament. Because of the ball-and-socket appearance of this joint, it is often termed "coxa pedis".

The talonavicular joint and the anterior part of the talocalcaneal joint are collectively known as the talocalcaneonavicular joint and may share the same joint space.
