Bone age in children and adolescents is usually determined by examining x-rays of the left wrist and then determining the age of the bones by judging the number of carpal bones in the x-rays. That is, after checking the x-rays and comparing them with pictures of normal bone age, bone age is judged. Based on the bone age and the adolescent growth chart, we will determine whether the height and weight are within the normal range. If it is low or delayed, growth hormone treatment or physical exercise to improve sleep is needed to promote growth and development. Random and unregulated treatments can be counterproductive, so go to a developmental clinic and see a professional doctor for treatment.
