The calcaneocuboid joint is a vital link in lateral foot stability. The calcaneocuboid joint is formed by the calcaneus and cuboid bones. This joint is susceptible to sudden injury or chronic strain, which can cause this joint to partially dislocate or subluxate.

Injuries

The cuboid can be subluxated downward causing a swollen kind of ache along the central portion of the lateral border of the foot.
