Whether the epiphysis is closed or not can be determined by taking an x-ray, and the total cost ranges from 50 to 200 dollars. The total cost ranges from $50 to $200. The exact cost depends on the number of parts of the body that are x-rayed, the area where the x-ray is taken, the level of the hospital, and the sophistication of the equipment used for the test. For adolescents under 16 years old, the X-ray of the wrist and hand can basically determine whether the bones are closed or not, and the cost is about 50~80 RMB. For youths over 16 years old, since the epiphyses of the wrist and hand are basically closed, it is necessary to further examine the large joints such as the hips and knees to determine the closure of the bones, and it is necessary to shoot 2~3 parts of the joints to accurately determine the closure of the bones, and the cost is therefore between 100 and 200 RMB. Whether or not the epiphysis is closed is a common way to determine whether or not you can continue to grow. Theoretically, the epiphyses close after the age of 18. If the epiphyses are not closed, then there is still room for growth; if the epiphyses are closed, there is usually no more bone growth.
