Which bones make up the subtalar joint?

• A. Tibia and Fibula
• B. Navicular and Cuboid
• C. Talus and Calcaneus
• D. Femur and Tibia

Answer: (C)

The subtalar joint is the articulation between the talus (ankle bone) and the calcaneus (heel bone), sitting below the main ankle joint to enable inversion and eversion of the foot. That makes talus and calcaneus the bones that form this joint. The tibia and fibula create the ankle mortise with the talus, not the subtalar joint; the navicular and cuboid are midfoot bones that connect to the talus and other tarsals, not the subtalar articulation; and the femur with the tibia form the knee joint, far from this area.
