Which joint is between the calcaneus and the cuboid bone?

• A. Subtalar joint
• B. Calcaneocuboid joint
• C. Tibiotalar joint
• D. Talonavicular joint

Answer: (B)

In the hindfoot, the joint between the calcaneus (heel bone) and the cuboid is the calcaneocuboid joint. It forms the posterior part of the transverse tarsal joint (Chopart’s joints) and sits at the interface where the anterior surface of the calcaneus meets the posterior facet of the cuboid. This plane-type synovial joint allows small gliding movements that help adapt the foot to varying surfaces and contribute to overall foot motion when combined with the talonavicular joint in the transverse tarsal complex. For context, the subtalar joint sits between the talus and calcaneus and mainly enables inversion and eversion of the foot; the tibiotalar joint is the ankle joint between the tibia/fibula and the talus; and the talonavicular joint is between the talus and the navicular bone.
