To check whether the epiphysis is closed, you can either consult a pediatrician or an orthopedic surgeon. Generally, an X-ray of the wrist joint can be taken to clarify whether epiphyseal closure has occurred. If the x-ray shows that the epiphysis and epiphysis have fused as one and the posterior line has disappeared, this is evidence that the epiphysis has closed. A closed epiphysis means that the bones have lost their potential for growth and widening, which means that they can no longer grow taller. If the epiphysis and epiphysis still have translucent lines, it means that the epiphysis has not yet closed. In this case, the bones still have the potential to grow, and it is important to promote growth through active sports, adequate sleep and a reasonable and balanced diet.
