Calcaneocuboid joint

The calcaneocuboid joint (Latin: articulatio calcaneocuboidea) is a synovial saddle type articulation between the tarsal bones of the foot. This joint is located between the calcaneus and cuboid bone.

Articulating structures of calcaneocuboid joint

The articular surfaces of the calcaneocuboid joint include the following:

  • Anterior articular surface of the calcaneus
  • Posterior articular surface of the cuboid bone

Joint capsule and ligaments

The calcaneocuboid joint is embraced by a fibrous joint capsule that posteriorly is thickened as the dorsal calcaneocuboid ligament. This joint is strengthened by three following ligaments:

  • Calcaneocuboid part of the bifurcate ligament - bifurcate ligament is a strong Y-shaped band that is attached to the calcaneus and distally divides into calcaneocuboid and calcaneonavicular parts; the calcaneocuboid part attaches to the cuboid bone;
  • Dorsal calcaneocuboid ligament - attaches to the calcaneus; located lateral to the bifurcate ligament, and extends to the dorsolateral side of the cuboid bone;
  • Long plantar ligament - the longest ligament of the foot; it is attached to the calcaneus and extends to the plantar surface of the second to fifth metatarsal bones;
  • Plantar calcaneocuboid ligament (short plantar ligament) - a short, wide band that extends from the anterior calcaneal tubercle to the plantar surface of the cuboid bone.

Movements of calcaneocuboid joint

The calcaneocuboid joint allows only limited and small amplitude movements. They include the gliding and rotational motions between the calcaneus and cuboid bone.
