The following measures are needed to intervene in the case of small bone age in children. First, children should be given growth hormone, because some children’s bone age is small due to the lack of growth hormone in their bodies. Secondly, thyroxine tablets should be given to children in time. Some children’s small bone age is caused by congenital hypothyroidism, which can lead to small bone age and delayed growth and development. When thyroxine tablets are given to children, the bone age will slowly catch up to the level of normal children.
