To understand an ankle fracture, first we must define which bones make of the ankle joint.

ankle joint anatomy
  • The tibia. This is the largest bone of your leg and is also know as your shin bone. The tibia's lower end curves around the inside of you ankle to become a structure called the medial malleolus, which you can feel at the inside of your ankle.
  • The fibula. This is the thinner of the two bones of the lower leg. It starts just below your knee and course down the outside of your leg to bone a structure called the lateral malleolus, which you can feel on the outside of your ankle.
  • The talus. This is a wedge-shaped bone that is located deep inside the ankle, located between the heel bone and the ends of the tibia and fibula. The talus supports the lower ends of the tibia and fibula. You generally cannot feel this bone as it is deep in the ankle.

There are many ways to fracture an ankle bone, the most common injuries involve a sudden sharp twist of the ankle. Ankle fractures are common injuries among people of all ages, interests and lifestyles. People involved in a wide range of athletic activities, including basketball players, snowboarders, soccer players and football players are at high risk of ankle fractures because of the physical demands placed on their ankles. Ankle fractures also occur during slips on icy pavement, falls from a high place, or direct impacts to the ankle during a car crash or motorcycle accident. High-impact ankle injuries are especially dangerous if the bone pokes through the skin and is exposed to the enviroment as this can allow the area to become contamined and lead to an increased chance of infection.

If you have a fractured ankle, your podiatric symptoms probably may include:

  • Pain at the site of the fracture, which in some cases can extend from the foot to the knee
  • Significant swelling, which may occur along the length of the leg or may be more localized
  • Blisters may occur over the fracture site. These should be promptly treated by a foot and ankle surgeon.
  • Bruising that develops soon after the injury
  • Inability to walk—however, it is possible to walk with less severe breaks, so never rely on walking as a test of whether a bone has been fractured
  • Change in the appearance of the ankle – it will look different from the other ankle
  • Bone protruding through the skin—a sign that immediate care is needed. Fractures that pierce the skin require immediate attention because they can lead to severe infection and prolonged recovery.

Diagnosis

A Thorough podiatric history and physical examination along with x-rays of the injured ankle are generally used to make the diagnosis and determination if surgical management is necessary.

Treatment of ankle fractures depends upon the type and severity of the injury. At first, the Podiatrist will want you to follow the R.I.C.E. protocol:

  • Rest: Stay off the injured ankle. Walking may cause further injury.
  • Ice: Apply an ice pack to the injured area, placing a thin towel between the ice and the skin. Use ice for 20 minutes and then wait at least 40 minutes before icing again.
  • Compression: An elastic wrap should be used to control swelling.
  • Elevation: The ankle should be raised slightly above the level of your heart to reduce swelling.

If no surgical intervention is required, the extremity is generally placed in a cast or fracture boot for 6 to 8 weeks. Weight bearing will be initiated once the podiatrist determines that sufficient healing has taken place to allow the ankle to tolerate weight. If surgery is required, generally, plates and screws will be inserted into the bones to reconstruct the ankle joint. Recovery times will be determined by the foot and ankle surgeon based on numerous factors. Physical therapy is generally required to help restore normal range of motion and strength to your ankle joint.

If an ankle fracture is treated promptly and properly, the prognosis is good. Overall, about 80% of all sports-related ankle fractures heal without any long-term complications. However, as with any significant injury near a joint, arthritis may develop years later.
