Calcaneocuboid articulation
Encyclopedia
The calcaneocuboid articulation is the joint between the calcaneus and the cuboid bone.

Ligaments

The ligaments connecting the calcaneus with the cuboid are five in number, viz., the articular capsule:
  • the dorsal calcaneocuboid ligament
    Dorsal calcaneocuboid ligament
    The dorsal calcaneocuboid ligament is a thin but broad fasciculus, which passes between the contiguous surfaces of the calcaneus and cuboid, on the dorsal surface of the joint....

    Bifurcated ligament
    The bifurcated ligament is a strong band, attached behind to the deep hollow on the upper surface of the calcaneus and dividing in front in a Y-shaped manner into a calcaneocuboid and a calcaneonavicular part.* The calcaneocuboid ligament is fixed to the medial...

Movements

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 (kinesiology)
Eversion is the movement of the sole of the foot away from the median plane. It occurs at the subtalar joint.Peroneus longus and peroneus brevis evert. Both muscles are innervated by the superficial fibular nerve....

In mathematics, an involution, or an involutary function, is a function f that is its own inverse:-General properties:Any involution is a bijection.The identity map is a trivial example of an involution...
