Sprain
Sprain
A sprain injury results when the ligament in a joint is stretched beyond its capacity. Symptoms involve swelling of the affected joint, tenderness, instability and decrease range of motion. Sprains range in severity from Grade I to Grade III, and both Grade I (mild) and II (moderate) sprains can be treated conservatively by rest, ice, compression and elevation (RICE) and range of motion and stretching exercises. Grade III (severe) sprains involve a complete tear of the ligament and can also be treated by conservative measures but occasionally require surgical reconstruction.
