The sprain occurs because of a false movement that hurts the joint. It twists and the ligaments around it distend. This is the benign sprain.
Serious sprains occur when one or more ligamentous bundles break, that is, when the ligaments tear like a piece of tissue. In more severe cases, ligamentous rupture may be associated with bone tearing where the ligament is normally attached.
Moreover, as the anatomical region around a joint is vascularized, small vessels can also tear and cause extravasation of the blood and the appearance of a hematoma (a blue).The causes of sprains are most often traumatic. They mostly occur in sports.
Ankle sprains are the most common sprains. They account for approximately 20% of all sports injuries and are the most common reason for consultation in trauma.
Any type of sport can be involved in the ankle sprain, regardless of the level. Nevertheless, they occur mainly in collective sports (football, basketball, volleyball) with jumps and changes of support.
There are certain factors that favor the occurrence of a sprain:
- the use of inappropriate shoes (high heels for example),
- muscle weakness,
- constitutional flexibility,
- overweight, etc.
