The state of the epiphyses can be seen by examining plain radiographs, also known as plain films and X-rays. Usually the most important places to check are the knee and ankle joints, the epiphyses of these two places are related to most of the height, and the presence of epiphyses signifies that there is still room for the long bones of the body to grow and develop. Arm bones, thigh and calf bones are long bones, when the epiphysis of the thigh and calf completely disappeared, the length of the lower limbs can’t continue to grow, but it doesn’t mean that the human body’s height can’t grow, because height is also affected by the development of the spine, even if the epiphyses are completely closed, the spine can still be stretched because of appropriate exercise, adequate nutrition, sufficient sunlight exposure to elongate, the influence of all these factors will make the People continue to grow taller.
