What does it mean if bone age is delayed?

Constitutional growth delay They usually have a delayed “bone age,” meaning their bones mature at a slower rate than their age. They also tend to reach puberty later than their peers. This leads to a below average height in early teenage years, but they tend to catch up with their peers in adulthood.

Are bone age tests accurate?

Since boys have achieved 99\% of their adult height when the bone age reaches 16.5 years and girls have 99\% of their adult height when the bone age reaches 14.5 years, we can determine how many years of growth a child has yet to experience from the bone age study.

Why is my bone age older than me?

Bone age may be affected by several factors, including gender, nutrition, as well as metabolic, genetic, and social factors and either acute or chronic diseases, including endocrine dysfunction (3–9).

What does bone age indicate?

The bone age study can help evaluate how fast or slowly a child’s skeleton is maturing, which can help doctors diagnose conditions that delay or accelerate physical growth and development.

How can you treat delayed puberty?

If the delayed puberty is inherited, no treatment is usually needed. In some cases, treatment may be done with hormone therapy. This helps to cause secondary sexual characteristics to occur. In other cases, surgery may be done to correct a physical problem.

Can delaying puberty increase height?

Experiments of nature and clinical observations have provided indications that postponing puberty may increase final height in short children.

Which of the following is most useful for bone age evaluation?

Radiography of the hand & wrist is the commonest modality used to calculate bone age. Automated methods for evaluation of hand and wrist radiographs are also being developed which reduce inter rater variability compared to manual methods.

How does age affect bone growth?

People lose bone mass or density as they age, especially women after menopause. The bones lose calcium and other minerals. Between each bone is a gel-like cushion (called a disk). With aging, the middle of the body (trunk) becomes shorter as the disks gradually lose fluid and become thinner.

Is bone age delay in growth hormone deficiency?

GH and IGF-1 are traditionally considered potent stimulators of bone growth. In children with GH deficiency (GHD), bone age (BA) is significantly delayed compared to chronological age (CA). After GH treatment, increased serum IGF-1 or GH levels stimulate growth plate development and result in BA progression.

When should I be worried about delayed puberty?

There’s not usually any need to worry if puberty does not start around the average age, but it’s a good idea to speak to your GP for advice if it starts before 8 or has not started by around 14. In some cases, early puberty or delayed puberty could be a sign of an underlying condition that may need to be treated.

What is a delayed bone age in a child?

Delayed bone age A delayed bone age means that the bones think they are younger than the child actually is. This can mean catch up growth after peers have stopped growing. A delayed bone age can happen for many reasons, but a common one is due to late puberty and can run in families.

What is the bone age of a 10 year old?

His bone age at the time (red dot) is 8 years 6 months, which is at the 25th percentile for height. A year later he is off the height chart, taller than over 97\% of boys his age, but the bone age is 10 years 9 months, again at the 25th percentile.

What is the average age of bone growth spurt in males?

The growth spurt of boys occurs on average at 14.2 years of bone age. Girls on the other hand have menarche at bone age 13.2 years, on average. The following illustraions show a series of images from the first Zurich Longitudinal Study (courtesy of Zurich Univ) show annual X-rays of the same bone.

What does advanced bone age mean for height?

An advanced bone age needs further evaluation to identify the cause. If the bone age equals the actual age, you can estimate the final height to be about the same percentage as the current height. We often repeat bone ages to see if they are changing at a different rate than the child grows.
