What are the two main bones in the hindfoot?

The two main bones in the hindfoot are the talus and calcaneus. The talus is the bone that sits above the calcaneus (the heel bone) and plays a crucial role in the ankle joint, connecting the foot to the leg. It articulates with the tibia and fibula, allowing for movement during walking, running, and jumping. The calcaneus, being the largest bone in the foot, provides leverage while walking and serves as an attachment point for the Achilles tendon, which is vital for propulsion during movement.

The other choices include bones that belong to different sections of the foot or do not represent the primary bones of the hindfoot. The cuboid and navicular are part of the midfoot, while metatarsals and phalanges are part of the forefoot. The cuneiforms and navicular also belong to the midfoot. Understanding the anatomy of the foot is essential for recognizing how each bone contributes to foot function and mechanics, particularly in the context of injuries or conditions affecting mobility.
