It is up to the doctor to decide whether a CT or X-ray is needed for a fracture review. The doctor will decide mainly based on the fracture site and time and the growth of bone scabs. Generally speaking, fractures in the backbone of extremities can be reviewed with ordinary X-rays, but in the case of flat bones, such as the skull, scapula, clavicle, ribs, and the pubic bone and sit bones of the pelvis, CT is required for examination. The bone morphology of the above parts is not standardized, and the general X-ray does not show the fracture healing, so CT is needed for examination. The vertebrae and the growth of bone scabs in hidden areas, such as the femoral neck, femoral head, humeral head, the eight carpal bones of the wrist, and the tarsal bones of the foot, need to be reviewed using CT, which shows more clearly.
