Which bone of the foot is located on the medial side and articulates distally with the three cuneiforms, proximally with the talus, and laterally with the cuboid?

• A. Navicular
• B. Cuboid
• C. First cuneiform
• D. Talus

Answer: (A)

The main idea is recognizing the midfoot bone that sits on the medial side and forms specific joints: proximally with the talus, distally with all three cuneiforms, and laterally with the cuboid. That description matches the navicular. It acts as a keystone of the medial column, connecting the talus to the three cuneiforms (medial, intermediate, and lateral) and to the cuboid on the lateral side, facilitating transfer of forces across the midfoot. The cuboid is more lateral and connects with the calcaneus and metatarsals, not all three cuneiforms. The first cuneiform sits distal to the navicular and does not articulate with the talus, and the talus largely relates to the tibia/fibula and calcaneus with only a single distal articulation to the navicular. So the bone described is the navicular.
