Which joint forms the lateral column of the midfoot?

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

Answer: (C)

The outer, lateral column of the midfoot is defined by the connection between the hindfoot and the midfoot on that side. The joint that directly links the calcaneus to the cuboid forms this boundary, making the calcaneocuboid joint the key articulation for the lateral column. The subtalar joint lies between the talus and calcaneus and mainly governs hindfoot motion, the talonavicular joint connects the talus to the navicular and belongs to the medial column, and the tarsometatarsal joints bridge the midfoot to the forefoot. Thus, the calcaneocuboid joint best defines the lateral midfoot column.
