Which bone is the second or intermediate cuneiform?

Which bone is the second or intermediate cuneiform?

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

Answer: (D)

The bone in question is the one in the middle of the three wedge-shaped cuneiforms in the midfoot. The cuneiforms are arranged from medial to lateral as first (medial), second (intermediate), and third (lateral). So the second cuneiform is the intermediate one lying between the other two, articulating with the navicular proximally and with the base of the second metatarsal distally. The talus is a different ankle bone, and the navicular is a different proximal foot bone; the first cuneiform is the medial one, not the middle. Thus the second or intermediate cuneiform is the bone you’re identifying.
