Calcaneocuboid joint explained

Calcaneocuboid joint
Components:calcaneus, cuboid bone

The calcaneocuboid joint is the joint between the calcaneus and the cuboid bone.

Structure

The calcaneocuboid joint is a type of saddle joint between the calcaneus and the cuboid bone.[1]

Ligaments

There are five ligaments connecting the calcaneus and the cuboid bone, forming parts of the articular capsule:

Function

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 involution.[3]

Clinical significance

The calcaneocuboid joint may be affected by a calcaneal fracture.[4] This may be a sign of a worse fracture, associated with worse outcomes (such as osteoarthritis) after treatment.
