Broken ankle

Also called Ankle fracture

A broken ankle is a break in one or more of the bones that make up the ankle joint. It usually happens after twisting the ankle, a fall or a sports injury. It can be hard to tell from a bad sprain without an X-ray.

What it is

Many broken ankles heal in a boot or cast in about 6 weeks. Breaks that make the joint unstable may need surgery with plates and screws.

Physiotherapy helps get back strength and movement. Full recovery can take several months.

Common signs

  • Pain and swelling around the ankle
  • Bruising
  • Being unable to put weight on the foot
  • The ankle looking out of shape

How it is usually diagnosed

  • Examination
  • X-ray
  • CT scan for complex breaks

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • X-ray reports and follow-up X-rays
  • Fracture clinic letters
  • Operation notes if surgery was done, including any metalwork
  • Physiotherapy plans

Questions to ask your doctor

  • How long will I be in a boot or cast, and can I put weight on it?
  • Do I need blood-thinning injections while my leg is immobilised?
  • When can I drive and return to sport?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • A foot that is cold, pale or numb, or bone breaking through the skin: call 112
  • Calf pain and swelling or sudden breathlessness while in a cast
