Taking an epiphyseal DR is usually sufficient and costs around $100~300. Epiphyseal DR filming is an examination method to observe the healing of the epiphysis. Commonly used parts are wrist joint and knee joint. The wider the epiphyseal gap, the greater the growth potential of the bone and the greater the increase in height. The smaller the epiphyseal gap, the smaller the growth potential of the bone. Once the epiphysis completely heals and becomes a white line, it means that the bone stops growing completely and the height no longer increases. In order to grow taller, you need to strengthen the nutrition before the epiphysis completely closed, appropriate physical exercise and ensure sufficient sleep, can promote growth and increase height.
