Fibula fracture

Fracture of the fibula, the bone in the lower part of the leg next to the tibia, where it runs from below the knee to the ankle, along the outside of the leg.

The cause is usually traumatic, due to a fall from a certain height or as a result of a car accident. It rarely happens because the bone wears away, as is usually the case with other large bone fractures.

Symptoms include pain, swelling, bruising, difficulty moving and/or walking on the affected leg.

The diagnosis is made clinically by asking about the history and by physical examination. An x-ray is taken to confirm the diagnosis.

Treatment is based on reduction and immobilisation of the fracture with a cast. If the fracture is complex, it may need to be repaired surgically with nails and screws. Pain and inflammation should be treated with painkillers and anti-inflammatories, and it is advisable not to put weight on the limb or make sudden movements until the bone has set and fully healed.

If you have a cast on and lesions appear on the skin, the colour of the fingers changes, swelling increases or you notice any strange symptoms, you should see a doctor for assessment.
