Causes of Sprains
Sprains can be caused by the following:
- Trauma, twisting or overextension of the foot and ankle. These are common in many sports and activities. When the foot “turns over,” a sprain is the common result. This happens fairly frequently in court sports, especially basketball and tennis, as well as in turf sports such as soccer, football, lacrosse and field hockey.
- Walking and running on uneven surfaces.
- Any movement that suddenly places the joint in an unnatural position. Most frequently, sprains occur in the ankles; other common locations include the wrists, fingers (primarily the thumbs) and knees.
