Which ankle bone articulates with the tibia and fibula?

• A. Talus
• B. Tibia
• C. Fibula
• D. Metatarsals

Answer: (A)

The bone that forms the ankle joint by connecting with both the tibia and fibula is the talus. It sits between the shin bones (the tibia and fibula) and the heel bone, and its upper surface has articular facets that fit with the distal ends of the tibia and fibula to create the ankle (talocrural) joint. This setup lets the foot move up and down while the tibia and fibula form the surrounding socket. The calcaneus sits below the talus and articulates with it, not with both leg bones, while the metatarsals are part of the foot, not the ankle. So the talus is the bone that directly articulates with both the tibia and fibula at the ankle.
