Question: what does a bone age x ray tell

title: Bone age
text: Bone age is the degree of maturation of a child 's bones . As a person grows from fetal life through childhood , puberty , and finishes growth as a young adult , the bones of the skeleton change in size and shape . These changes can be seen by x-ray . The `` bone age '' of a child is the average age at which children reach this stage of bone maturation . A child 's current height and bone age can be used to predict adult height . For most people , their bone age is the same as their biological age but for some individuals , their bone age is a couple years older or younger . Those with advanced bone ages typically hit a growth spurt early on but stop growing early sooner while those with delayed bone ages hit their growth spurt later than normal . Kids who are below average height do not necessarily have a delayed bone age ; in fact their bone age could actually be advanced which if left untreated , will stunt their growth .
