Ankle Fracture

An ankle fracture is a break in one or more bones around the ankle. An examination and imaging are often needed to distinguish it from a sprain.

Overview

About ankle fracture

An ankle fracture is a break in one or more bones around the ankle. An examination and imaging are often needed to distinguish it from a sprain.

Causes

What can cause it?

Ankle fractures may follow twisting, falling, sports injury, or direct impact.

Stress fractures and fractures related to weakened bone can occur with less obvious trauma.

Symptoms

What a patient may notice

Symptoms vary from person to person. Possible signs may include:

  • Severe pain, swelling, or bruising
  • Inability to bear weight
  • Deformity or tenderness directly over a bone
Exams and Tests

How clinicians find the cause

A clinician checks deformity, tenderness, swelling, skin, blood flow, sensation, and ability to bear weight. X-rays confirm most fractures; CT or MRI may be used for complex or subtle injuries.

Treatment

Treatment and next steps

  1. 1

    Treatment may include a splint, cast, boot, reduction to restore alignment, or surgery.

  2. 2

    Weight-bearing instructions depend on fracture stability and must be followed carefully.

  3. 3

    Open fractures or compromised circulation need emergency treatment.

Supporting recovery

  • Keep weight off the ankle until evaluated when fracture is possible.
  • Support the ankle, elevate it, and apply wrapped ice for short periods.
  • Do not attempt to straighten a deformed ankle.
Outlook (Prognosis)

What to expect

Most ankle fractures heal with appropriate protection, alignment, and follow-up, but recovery time depends on the bones involved, whether the fracture entered the joint, and whether surgery was needed. Many people require at least 6 to 10 weeks for bone healing followed by gradual rehabilitation to restore motion, strength, and balance.

Possible complications

  • Delayed healing, failure to heal, or healing in an incorrect position
  • Long-term stiffness, weakness, swelling, pain, or post-traumatic arthritis
  • Skin, wound, nerve, circulation, blood-clot, or infection complications, particularly after a severe fracture or surgery
Follow-up: Keep orthopedic and imaging appointments. Return immediately for increasing pain, numbness, severe swelling, skin breakdown, or toes that become pale, blue, or cold.
Same-day evaluation

When to Contact a Medical Professional

A same-day medical evaluation is recommended, especially when symptoms are severe, worsening, or accompanied by fever, vomiting, weakness, or significant pain.

Go to the emergency department for an open wound over the bone, obvious deformity, numbness, or a pale, blue, or cold foot.
Call 911 now

Get emergency help for severe trouble breathing, new chest pressure, fainting, seizure, sudden weakness on one side, uncontrolled bleeding, blue or gray lips, or a person who is difficult to wake.

Prevention

Ways to lower risk

  • Use appropriate footwear and protective equipment.
  • Build strength and balance and increase activity gradually.
  • Discuss bone-health evaluation after a low-impact fracture.
