A sprain happens when the ligaments of the body become stretched or torn. A ligament is a fibrous band of tissue that connects the bones at a joint. This is why sprains are localized around joints such as ankles, knees and shoulders. Causes & symptoms. Normally, the ligament can expand and snap back into place when a person moves. Sometimes, though, the ligament is pushed beyond its normal capabilities and causes a sprain. Any joint can be affected by a sprain if the ligament is suddenly pushed, twisted or impacted. The most common type of sprain is an ankle sprain, according to the Mayo Clinic.
