Ankle
The ankle joint is the point where three bones meet: the shin bone (tibia), the calf bone (fibula) and the ankle bone (talus). The ankle, also known as the talocrural joint, is a ball joint that ensures your foot can move up and down in a smooth and supple way. There is a complex system of ligaments and tendons around the ankle joint.
The lower ankle joint is located between the ankle bone and the heel bone (the heel). This joint ensures supple sideways movement. In this joint, the so-called inversion movement takes place and this is where extreme inversion can result in an ankle sprain.
This complex group of bones, joints and ligaments is very mobile and strong, but they are also vulnerable, especially on the outer side.
