Articular surface for cuboid bone

The articular surface for the cuboid bone of the calcaneus is the anterior articular facet on the calcaneus that forms the calcaneocuboid joint, a key component of the transverse tarsal (Chopart) joint. This surface enables articulation between the calcaneus and cuboid bone and plays an important role in midfoot stability and foot biomechanics.

It is an essential anatomical landmark in foot anatomy, orthopedic evaluation, trauma assessment, and imaging of the hindfoot and midfoot.
