Whether a CT or an X-ray is done for a fracture review depends on the exact location and shape of the fracture. If the fracture is very obvious and the diagnosis is determined by X-rays, when the fracture is reviewed afterwards naturally X-rays are taken, and the fracture growth can be clearly seen by X-rays. If the diagnosis is determined by CT after the fracture, it means that the fracture is not obvious or even relatively concealed. At this time, X-rays cannot be done to review the fracture, and CT examination of the fracture site is still required so that the degree of healing and healing of the fracture can be more clearly found.
