The most intuitive and simple way to determine epiphyseal closure is to go to the hospital for an X-ray examination. Of course, slower height growth and disappearance of growing pains may be signs of epiphyseal closure, which can indirectly suggest epiphyseal closure: 1. slower height growth: when a child’s height growth slows down significantly, or even no growth in the past two years, epiphyseal closure can be considered; 2. disappearance of growing pains: some children often have lower limb growing pains, or drowsiness, large appetite, etc. during the high speed of height development. When these manifestations gradually disappear, it may suggest that the epiphysis will be closed; 3. Changes in body size: children in the peak growth period usually have underdeveloped muscles and a tall body shape, if the child’s height growth is slow, the muscles are gradually full and strong, and the weight increase is obvious, it may suggest that the epiphysis is closed. In addition, attention should be paid to the age of the child. Although age is not a necessary factor in determining epiphyseal closure, once the child reaches the age of 20, the epiphysis is basically completely closed and no further changes in height will occur. Parents and children should be aware that to determine whether the epiphysis is closed, it is advisable to go to the hospital for an X-ray examination, which is done through an orthogonal X-ray of the left wrist.
