Which joint forms the lateral column of the midfoot?

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

Answer: (C)

The lateral column of the midfoot is defined by the connection between the hindfoot and the cuboid, specifically the calcaneocuboid joint. This joint links the calcaneus (heel bone) to the cuboid, forming the lateral boundary of the midfoot and supporting the stability of the outer part of the arch, including the fifth metatarsal region. The other joints listed don’t define this column: the subtalar joint sits between the calcaneus and talus at the hindfoot, the talonavicular joint lies medially between the talus and navicular, and the tarsometatarsal joints connect the midfoot to the forefoot. Thus, the calcaneocuboid joint best forms the lateral midfoot column.
