Which ankle bone articulates with both the tibia and fibula?

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

Answer: (A)

The talus is the ankle bone that articulates with both the tibia and fibula. It sits between the lower ends of the leg bones and forms the ankle joint by meeting the tibial and fibular malleoli at its upper surface, creating the ankle mortise. This arrangement lets the weight of the body pass from the tibia through the talus into the foot and enables the hinge-like motion of the ankle (dorsiflexion and plantarflexion). The tibia and fibula also connect to each other at the distal tibiofibular joint, but it is the talus that directly interfaces with both to form the ankle joint. The metatarsals are in the foot, not part of the ankle articulation.
