Which bones make up the ankle joint along with the talus and tibia?

The ankle joint, also known as the talocrural joint, is formed by the interaction of several bones. The primary bones involved in the ankle joint are the talus, tibia, and fibula. The tibia is the larger of the two bones in the lower leg and forms the medial side of the ankle joint. The fibula, which runs parallel to the tibia on the outside of the leg, plays a crucial role in stabilizing the ankle joint by articulating with the talus. This connection allows for the essential movements of the ankle, including dorsiflexion and plantarflexion.

The other bones, such as the cuboid, navicular, and metatarsals, are involved in the foot structure but do not directly articulate to form the ankle joint in conjunction with the talus and tibia. The cuboid and navicular are part of the tarsal bones and help in forming the arches of the foot, while the metatarsals are the long bones of the foot that connect to the toes. Thus, the fibula is the correct answer as it is one of the key components of the ankle joint structure.
