The talocalcaneonavicular joint is a
Structure
As its shape suggests, this joint is a synovial ball-and-socket joint.[1] It is composed of three articular surfaces:
- The articulation between the medial talar articular surface on the sustentaculum tali of the superior calcaneus and the corresponding medial facet found inferiorly on the talus neck[2]
- The articulation between the anterior talar articular surface of the superior calcaneus and the anterior facet of the corresponding talus found inferiorly on the talar head
- The articulation between the articular surface of navicular and the head of talus (talonavicular joint)[2]
Ligaments
The
The calcaneonavicular part of the bifurcated ligament extends from the dorsolateral side of calcaneus (near the tarsal sinus) to the lateral side of the navicular.[1] It reinforces the joint particularly laterally where the talus articulates with the navicular.[2]
The dorsal talonavicular ligament extends from the dorsal aspect of the foot from the neck of the talus to the navicular.[1][2]
The socket of this joint is formed by the concave articular facets of the navicular, calcaneus, calcaneonavicular part of bifurcate ligament and the spring ligament (plantar calcaneonavicular ligament), where the ball is formed by the convex talus.
