Fracture of one of the bones that make up the joint that connects the leg to the foot. The ankle joint is formed by the long bones of the leg (tibia and fibula) and the talus of the foot. It is held together by lateral, medial, anterior and posterior ligaments. Ankle fractures are the most common fractures of the lower extremity and are often associated with dislocation.
The most common causes are road traffic accidents involving twisting of the ankle and sports or recreational injuries.
It is characterised by severe pain that is increased by movement or when the foot is placed on the ground. The joint swells quickly and a haematoma may develop. In some cases, the pain can radiate into the knee.
Diagnosis is made by asking about the symptoms, physical examination and x-rays of the ankle in different views. A CT-scan or MRI may be needed to further investigate tendon and ligament injuries.
