Fracture review need to take CT or X-ray need to be decided by the doctor, the doctor is mainly based on the fracture site and time as well as the growth of the bone scab to decide. Generally speaking, the fracture of the trunk of the limbs can be reviewed with ordinary X-rays, but if it is a flat bone, such as the skull, scapula, clavicle, ribs, and the pelvis of the pubic bone, sciatica, CT is needed to be used to check. The shape of the bones in the above areas is not standardized, and normal X-rays do not show fracture healing, so it is necessary to use CT for examination. Vertebrae and the growth of bone scabs in hidden areas, such as the neck of the femur, head of the femur, head of the humerus, the eight carpal bones of the wrist, and the tarsal bones of the foot, need to be reviewed using CT, which shows more clearly.
