The standard height of an 11-week-old boy is 145.3 cm. If the height of an 11-week-old boy is between 140.8 and 149.9 cm, it is considered approximately normal. If the height of an 11-week-old boy is below 132.9 cm, he is considered to be short. 11-week-old boys are about to enter puberty, so if their height does not reach the standard value, they need to take their children to the hospital for a bone age test, which is an orthopantomogram of the left wrist joint and can truly measure whether a child’s height is normal or short. If the child’s height is indeed short or slightly short after the bone age test, parents need to actively intervene and treat the child under the guidance of a doctor. Once a child reaches puberty, there will be a rapid increase in height, followed by a downward curve in height, leaving little room for growth. If the child is still short at a later stage, there is little point in treating it and the effect is not good, so early detection requires active intervention and treatment.
