Which bone is the cuboid?

Which bone is the cuboid?

• A. Talus
• B. Navicular
• C. Cuboid
• D. Second or intermediate cuneiform

Answer: (C)

The main idea is recognizing a specific tarsal bone by its location and connections in the foot. The cuboid is the cube-shaped bone on the outer (lateral) side of the midfoot. It sits behind the metatarsals four and five and in front of the calcaneus, with proximal/medial relations to the lateral cuneiform and navicular and distal relations to the fourth and fifth metatarsals. This distinct lateral position and its articulations set it apart from the other bones: the talus is the ankle bone above the calcaneus, the navicular lies Medially in the midfoot, and the second (intermediate) cuneiform is a separate bone between the navicular and the second metatarsal.
