Where do sprains usually occur?

Although sprains can occur in both the upper and lower parts of the body, the most common site is the ankle. The ankle is supported by several lateral (outside) ligaments. Most ankle sprains happen when the foot turns inwards as a person runs, turns, falls or lands on the ankle after a jump. This type of sprain is called an inversion injury.

The knee is another common site for a sprain. A blow to the knee or a fall is often the cause: sudden twisting can also result in a sprain.

The wrist is another area prone to sprains, typically when people fall on an out-stretched hand. Also a sprain to the thumb is common in skiing and other sports. The injury occurs when the ligament near the base of the thumb is torn.
