A sprain is a stretch or tear of a ligament. A ligament is a band of tissue that connects two bones. The sprain occurs when the ligament is extended beyond the normal range for a particular joint.

What are the causes and risks of the injury?

Sprains occur when a joint is knocked out of position by a fall, hard blow, or other injury. Some common causes of sprains include the following:

  • falls, particularly falls onto an outstretched arm
  • motor vehicle accidents
  • obesity or overweight
  • overstretching, such as during an exercise warm-up session
  • running on an uneven surface
  • sports injuries
  • work-related injuries, such as repetitive stress injuries from overusing a joint or extremity
