To determine if the epiphysis has closed, the patient can have a wrist radiograph taken to see if the epiphysis has closed. If the epiphysis has not closed, it usually means that there is still room for the human body to grow, and the long bones can still grow again, but if the epiphysis has already closed, it means that there is no more room for the human body to grow. In addition to observing whether the epiphysis is closed to know whether the human body can still grow taller, the most accurate thing is to observe the age of the bones, to know whether the age of the bones and the age of the human body are in line with each other, and whether there is any advancement or delay. According to the bone age, we can know the real biological age, and we can also know whether we need to intervene or not. For example, some people have an early start of the gonadal axis and have an early bone age, which will affect their lifelong height, and they can be adjusted to the gonadal axis under the guidance of a doctor and treated with growth hormone supplementation if necessary.
