A sprain, also known as a torn ligament, is damage to one or more ligaments in a joint, often caused by trauma or the joint being taken beyond its functional range of motion. The severity of sprain ranges from a minor injury which resolves in a few days to a major rupture of one or more ligaments requiring surgical fixation and a period of immobilisation. Sprains can occur in any joint but are most common in the ankle and wrist.
Sprains typically occur when the joint is taken beyond its functional range of motion.
There are certain factors which increase risk of sprains. Fatigue of muscles generally leads to sprains. When one suddenly starts to exercise after a sedentary lifestyle, sprains are quite common. While scientific studies are lacking, it is often thought that not warming-up is a common cause of sprains in athletes. Warming-up is thought to loosen the joint, increases blood flow and makes the joint more flexible.
A diagnosis of a sprain can often be made with a good degree of certainty by physical examination based on the clinical presentation and method of injury. In some cases, X-rays are obtained to ensure that there is no fracture. In some cases, particularly if the injury is prolonged or does not appear to be resolving as expected, magnetic resonance imaging (MRI) is performed to look at surrounding soft tissues and the ligament.
Although any joint can experience a sprain, some of the more common include:
The first modality for a sprain can be remembered using the acronym RICE. The treatment of sprains depends on the extent of injury and the joint involved. Medications like non-steroidal anti-inflammatory drugs can relieve pain. Topical NSAIDs appear to be as good as those taken by mouth.
Ice and compression (cold compression therapy) will not completely stop swelling and pain, but will help to minimize them as the sprain begins to heal itself. Careful management of swelling is critical to the healing process as additional fluid may pool in the sprained area.
