Sprains
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
