See also: Chopart joint line
Anatomy[Bearbeiten]
The articulatio tarsi transversa consists of the following parts:
- Lateral from the calcaneocuboid articulation between the calcaneus (heel bone) and the cuboid bone.
- Medially from the articulatio talonavicularis between the talus (ankle bone) and os naviculare (navicular bone)
The ligamentous apparatus of the joint consists mainly of the dorsal talonavicular ligament and the bifurcated ligament. Due to the tight ligament guidance and the resulting severely restricted range of motion, the joint is categorised as an amphiarthrosis.
