Bone-related tests generally require only radiographs and imaging to determine whether the bones are closing. Normal human bones gradually close at different ages and stages. Once a bone closes at a certain location, it means that the longitudinal length of the limb at that location has stopped growing, for example, if the epiphysis of the femur closes, it means that the longitudinal length of the femur has stopped growing. If the overall height of the body wants to determine whether the growth has stopped, it is necessary to check whether the latest closure of the epiphysis related to the height has occurred or not, generally need to carry out a radiographic examination of the bones around the pelvis to determine whether the epiphysis is completely closed or not, once the phenomenon of completely closed, the human body’s height will also stop growing.
