As with many types of fractures, the causes and risk factors can be divided into two types
  • 'High-energy' fractures: Large forces on strong bones
    • Ankle fractures are common among sports people who sustain high-speed falls and trauma
    • Other common causes of high-energy fractures are car accidents and falls from large heights 
  • 'Low-energy' fractures: Small forces on weak bones
    • In people with weak bones, almost any awkward movement can cause a fracture. Weakness in bones can be due to
      • Osteoporosis
      • Medications and other drugs; most commonly, people who need to take high doses of steroids for long periods of time are at risk of developing weak bones
      • 'Pathological fractures' – doctors refer to any condition that weakens a local area of bone , causing it to fracture, as 'pathological'. This can include any condition from infection to cancer, however these are relatively rare causes of ankle fractures.
