The hinge joint between the foot and the leg. The talus (uppermost bone in the foot) fits between the 2 bony protuberances formed by the lower ends of the tibia (the shinbone) and the fibula (the outer bone of the lower leg). Strong ligaments on either side of the ankle joint give it support. The ankle allows for up-anddown movement of the foot. An ankle sprain is one of the most common injuries. It is usually caused by twisting the foot over on to its outside edge, causing overstretching and bruising of the ligaments. Violent twisting of the ankle can cause a combined fracture and dislocation known as Pott’s fracture.
