Which three bones constitute the ankle joint?

The ankle joint is primarily formed by the articulation of three specific bones: the tibia, fibula, and talus. The tibia and fibula are the two long bones of the lower leg, with the tibia being the larger bone that bears most of the weight, while the fibula is thinner and supports the ankle. The talus, located above the heel bone (calcaneus), connects the foot to the leg and plays a crucial role in the movement and stability of the ankle.

When these three bones come together, they create a hinge-like joint that allows for dorsi- and plantarflexion movements—essential for walking, running, and various sports activities. The design of this joint is key to its function in weight-bearing and mobility.

In contrast, the other listed bone groups do not form the ankle joint. The cuboid, navicular, and cuneiform bones (the second group) are part of the midfoot and contribute to the structural integrity of the foot rather than the ankle. The calcaneus, talus, and navicular (the third group) are involved in the broader structure of the foot but not specifically in the ankle joint itself. Meanwhile, "Savoir" (an incorrect term in
