Overview
The ankles support the entire body weight and ankle injuries are very common. Each year, approximately 2 million patients are treated for ankle sprains and strains and ankle fractures are one of the most common injuries treated by orthopedists and podiatrists.
Anyone, from the most well-conditioned athlete to the most sedentary person, can experience an ankle injury. Usually, the cause is accidental (e.g., stepping into a pothole, slipping while getting out of the car). People who are overweight and those who wear high-heeled shoes are at an increased risk for ankle injuries.
Ankle injuries usually involve a sudden, unexpected, loss of balance that results in a sharp twist of the ankle. A strain occurs when a muscle or tendon overstretches. A sprain, which is more serious, occurs when strong connective tissue that connects one bone to another (ligaments) become overstretched.
In some cases, a ligament tears and may pull a fragment of bone with it. When a piece of bone is pulled away, it is known as an avulsion fracture.
Sprains may account for 85% of all ankle injuries and about 45% of all sports-related injuries. It is estimated that as many as 50% of patients who experience an ankle sprain will have a recurrence.
