Which bone is the ankle process known as malleolus?

• A. Malleolus
• B. Talus
• C. Calcaneus
• D. Navicular

Answer: (A)

Malleolus refers to the ankle projection itself. There are two, the medial malleolus on the inner (tibial) side and the lateral malleolus on the outer (fibular) side, and they form the bony sides of the ankle joint with the talus. The other bones listed are different parts of the foot—the talus sits under the leg to form the ankle joint, the calcaneus is the heel bone, and the navicular is a midfoot bone. So the ankle process is correctly named malleolus.
