Inversion and eversion of the foot

The terms "inversion" and "eversion" are used to describe the movements of the foot. "Inversion" refers to the movement in which the sole of the foot turns inwards relative to the lower leg, while "eversion" refers to the movement in which the sole of the foot turns outwards.

Example

An example of the use of these terms is when someone sprains their ankle, causing the foot to turn inwards. This is called an inversion injury. This can lead to damage to the ligaments on the outside of the ankle.
Eversion injuries occur much less frequently, because the outward mobility of the foot is not as great.

These terms are mainly used by (para)medical professionals, such as doctors and physiotherapists, to communicate more accurately about the location of an injury or problem. As a patient, you do not necessarily have to be familiar with these terms, but it can help you to better understand a medical report.
