The **ankle** is formed by the **talocrural joint**, which includes articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg (crural: relating to the leg or thigh). The superior aspect of the talus bone is square-shaped, providing three areas of articulation. The top of the talus articulates with the inferior surface of the tibia, transferring body weight from the leg to the foot. The sides of the talus are held firmly in position by its articulations with the medial malleolus of the tibia and the lateral malleolus of the fibula, which prevent lateral movement of the talus. The ankle is thus a uniaxial hinge joint that allows only dorsiflexion and plantar flexion of the foot. *LICENSES AND ATTRIBUTIONS CC licensed content, Shared previously Chapter 9.
