Sprains

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.
