Overview of Ankle Injuries

Overview of Ankle Injuries

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.

Risk Factors and Causes of Ankle Injuries

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.
