Complications

Complications of a broken ankle are uncommon but may include:

• Arthritis. Fractures that extend into the joint can cause arthritis years later. If your ankle starts to hurt long after a break, see your doctor for an evaluation.
• Bone infection (osteomyelitis). If you have an open fracture, meaning one end of the bone protrudes through the skin, your bone may be exposed to bacteria that cause infection.
• Compartment syndrome. This condition can rarely occur with ankle fractures. It causes pain, swelling and sometimes disability in affected muscles of the legs.
• Nerve or blood vessel damage. Trauma to the ankle can injure nerves and blood vessels, sometimes actually tearing them. Seek immediate attention if you notice any numbness or circulation problems. Lack of blood flow can cause a bone to die and collapse.
