Dislocation is an injury that results in a bone being moved out of place.
When this happens, the ligaments that hold the bone in place are torn. The bone can go back into the right place on its own or it may need to be replaced by a health care worker. Often, an injury that causes a fracture also causes a dislocation. A dislocated ankle is usually caused by a twisting injury or impact. To diagnose a dislocated ankle, the doctor will review how the injury occurred and your symptoms.
