What is a sprain?

A sprain specifically refers to an injury that occurs when a ligament, which connects bones at a joint, is stretched, torn, or damaged. This type of injury typically results from excessive force applied to a joint, such as during a fall, twist, or blow to the body that forces the joint out of its normal position. The damage to the ligament can result in pain, swelling, bruising, and reduced ability to move the affected joint.

The distinction between a sprain and other types of injuries is important for understanding treatment and recovery. For example, injuries involving muscles or tendons are termed strains, while fractures involve the breaking of bones, and dislocations refer to the bones at a joint moving out of their normal alignment. By recognizing a sprain as an injury specifically involving ligaments, one can better assess and manage the injury appropriately.
