Children 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.Īt birth, only the metaphyses of the " long bones" are present. Those with advanced bone ages typically hit a growth spurt early on but stop growing sooner, while those with delayed bone ages hit their growth spurt later than normal. For most people, their bone age is the same as their biological age but for some individuals, their bone age is a couple of years older or younger. ![]() A child's current height and bone age can be used to predict adult height.
