An ankle fracture is a break of a bone in the ankle joint. The joint is made up of 3 bones:
The ankle joint is supported by 3 groups of ligaments. An injury that causes a fracture may also damage one or more of these ligaments.

An ankle fracture can occur when the joint is forced beyond its normal range of motion. It can also be caused by a direct blow to the bone itself. Any form of ankle trauma may cause injury, including:
Factors that increase your chances of getting an ankle fracture include:
You will be asked about your symptoms, physical activity, and how the injury occurred. An examination of the injured area will be done.
Treatment will depend on the severity of the injury. Treatment includes:
Devices that may be used to hold the bone in place while it heals include:
Your doctor may prescribe pain medication. More x-rays will be ordered while the bone heals to ensure that the bones have not shifted position.
When your doctor decides you are ready, start range-of-motion and strengthening exercises. You may be referred to a physical therapist to help you with these exercises. Do not return to sports activity until your doctor says your ankle is fully healed. You will need near-normal motion and muscle strength.
It takes at least 6-8 weeks for even a simple ankle fracture to heal. It will be several months before you can return to intense physical activity.
