Ligaments of the medial aspect of the foot. (Calcaneocuboid labeled at bottom center.)
The ligaments of the foot from the lateral aspect. (Calcaneocuboid labeled at top, third from right.)
The ligaments connecting the calcaneus with the cuboid are five in number, viz., the articular capsule:
- the dorsal calcaneocuboid ligament,
- part of the bifurcated ligament,
- the long plantar ligament,
- and the plantar calcaneocuboid ligament.
The calcaneocuboid joint is conventionally described as among the least mobile joints in the human foot. The articular surfaces of the two bones are relatively flat with some irregular undulations, which seem to suggest movement limited to a single rotation and some translation. However, the cuboid rotates as much as 25° about an oblique axis during inversion-eversion in a movement that could be called obvolution-involution.
