X-rays of the ankle are categorized as orthopantomograms and lateral radiographs. When reading the radiographs, the first thing to look at is whether the density of the bone is uniform or not, the cortical part of the bone is brighter, the medullary cavity is relatively darker, but the distribution is generally uniform. It is important to see whether the density is uniform or not, whether there is any osteolytic destruction, whether there is any bone defect, and whether there is any growth of mass. The second thing to look at is whether there is a low density shadow on the bone, that is, the fracture. If there is a fracture, cortical fracture, or osteochondral fracture, there is no displacement, and the severity of the displacement. The third thing to look at is whether the gap in the ankle joint is symmetrical and isometric, and whether there is any narrowing of the gap or unequal gap, which is often indicative of subluxation of the ankle joint. Next, we can look at the soft tissues around the ankle joint to see if there is any swelling, and if there is any abnormal high-density shadow in the soft tissues, which mainly depends on the soft tissue condition. By reading these films, you can basically understand the structure of the ankle joint, the degree of injury, and whether the joint is in good position.
