What Is an Ankle Fracture?

An ankle fracture is a break in any bone of the ankle joint. It may be mild (like a bad sprain) or severe (including joint dislocation). Long-term pain and disability are possible.

What Causes an Ankle Fracture?

Causes include blows to the ankle, falls (landing on the feet), or, most often, twisting the ankle.

What Are the Symptoms of an Ankle Fracture?

Symptoms are pain, especially when putting weight on or moving the ankle, swelling, bruising, and a deformed joint.

How Is an Ankle Fracture Diagnosed?

The health care provider uses a physical examination and x-rays.

How Is an Ankle Fracture Treated?

Treatment may be similar to treatment of a sprain (rest, ice, elevation, compression, and using a brace for protection). It may involve surgery and use of screws and plates to hold bones together during healing.

Most often, a cast or removable splint holds bones in position until they heal. If a cast is used, lower leg muscles will be a bit weak after removal of the cast. Physical therapy will help this common side effect. Complications include failure to heal, poor blood flow to the foot or toes (if cast is too tight or swelling occurs in the cast), blood clots, and infection or bleeding related to surgery.

DOs and DON’Ts in Managing an Ankle Fracture:

  • DO reduce the risk of injury by warming up and stretching before exercising.
  • DO use good running shoes and run on an even surface when your health care provider says that you can resume exercising.
  • DO reduce your weight, if overweight.
  • DO keep fit.
  • DO take pain medicines as prescribed.
  • DO eat a diet with enough calcium to help healing.
  • DO keep your foot raised for the first few days and apply ice to your ankle the first day or so, to minimize swelling.
  • DO exercises or go to a physical therapist after cast removal to shorten recovery time and reduce the risk of developing a blood clot in the leg.
  • DO call your health care provider if you notice numbness, tingling, coldness, or darkening of your toes. The cast may be too tight or the ankle may be swollen, reducing blood circulation to your foot.
  • DO call your health care provider if you damage your splint or cast so that it is loose or allows your ankle to move more than it should.
  • DO call your health care provider if, after surgery, you have fever or you see redness, swelling, or pus at the incision (suggesting infection).
  • DO call your health care provider if you have increasing pain or cannot use your ankle at some time after surgery.
  • DO call your health care provider if you notice pain or swelling in your calf or leg, which may mean a blood clot.
  • DON’T spend too much time on your feet or with your foot hanging down. Don’t put heat on the ankle. Swelling may hurt circulation.
  • DON’T get a plaster or fiberglass cast wet.
  • DON’T stick things such as coat hangers, pencils, or knitting needles down the cast to scratch. If you poke the skin, you may get an infection.
  • DON’T remove your cast too soon. Early removal may allow another injury.
