What causes an ankle fracture?

Ankle fractures are often caused from severely twisting or rolling the ankle. They may also be caused from a fall, blow, accident, or sports injury.

Symptoms of an ankle fracture

Symptoms can include immediate and severe pain, swelling, and bruising. If the bone breaks through the skin, bleeding at the site can also occur. The ankle may look crooked, deformed, or bent. Also, it may be hard to move or use the ankle and foot as you would normally. You can't put weight on it.

Treating an ankle fracture

Treatment for an ankle fracture depends on where the bone is broken and how serious the break is. If needed, the bone is put back into place. This may be done with or without surgery. If surgery is needed, the surgeon may use devices, such as pins, plates, or screws to hold the bone together. Usually, you will wear a splint, brace, boot, or short leg cast to keep the bone in place and protect it from injury during healing. Other treatments may also be used to help reduce symptoms or regain function. These include:

• Rest. You may need to not walk or put any weight on the broken ankle for a period of time. Severe fractures need a longer limit on weight-bearing activities.

• Cold packs. Putting an ice pack over the injured area may help reduce swelling and pain. To make an ice pack, put ice cubes in a plastic bag that seals at the top. Wrap the bag in a clean, thin towel or cloth. Don't put ice or an ice pack directly on the skin.

• Compression. An elastic bandage may be wrapped around the ankle to help reduce swelling.

• Elevation. Propping up the ankle so that it is above your heart may ease swelling.

• Pain medicines. Prescription or over-the-counter pain medicines may help reduce pain and swelling. If needed, stronger pain medicines may be prescribed.

• Exercises. Your healthcare provider may give you certain exercises to do at home or with a physical therapist. These help restore strength, flexibility, and range of motion in the ankle and foot.

Possible complications of an ankle fracture

These can include:

• The bone doesn't heal well

• Weakness, stiffness, or loss of range of motion in the ankle

• Osteoarthritis in the ankle
