It is a painless procedure that exposes the individual to a very small amount of radiation. Afterwards, the image is compared to standard images from a bone development atlas, where the references were made on large studies of kids.
Bone age is measured in years. The growth of bones is possible thanks to a particular area within two ends of long bones - the growth plate. This is a hyaline cartilage plate, which consists of actively growing cells. These plates can be found in children's bones, and, in adolescents, they turn into an epiphysial line the residue of growth plate.
This replacement is called epiphysial closure or growth plate fusion. The fusions complete in age for girls and for boys.
Growth plates are easy to identify on an X-ray because they are softer and contain less minerals than standard bone. That makes them appear darker than the rest of the skeleton on the X-ray image. They look different at each age - thanks to that, a doctor can determine the bone maturity by simply reviewing its appearance. Then, the image is compared with the closest matching image from an atlas.
Observing a difference between a child's bone age and their chronological age may point to a growth problem, but it is not the rule. Some kids with perfect health can have a disparity in skeletal and chronological age. The control of bone age is done to assess the tempo of the maturing process of a child's skeleton.
This allows doctors to diagnose conditions that delay or accelerate physical growth. Using the skeletal age, physicians may predict:. The study is also used to monitor the treatment process of kids with growth deficiencies. There are plenty of factors that may affect growth:. Gilsanz, O. Ratib by Springer. Standardized growth charts are an essential tool used by doctors to determine whether a child is growing as expected.
They are based on regular measurements of a child's height, weight, head size, and BMI. You can check them here. They are also helpful for judging the onset of puberty in an older child.
Growth process differs between girls and boys. Female growth is fast in childhood, and when they reach puberty, it speeds up rapidly. They achieve adult height usually at the age of , or a couple of years after menstruation occurs the first time.
Following the growth charts from CDC, the average height of adult woman at age 20 is in cm. In the table below, you can find a few other numbers for different ages. Boys come into puberty later than girls. They start entering it at the age of , so the biggest growth happens around 2 years later than for girls. The rate of height growth for most boys slows down around 16 years old, but their body mass mainly muscles continue to develop. According to CBC, the average male height around 20 years old is Check below for the median height of boys during childhood and teenage years.
Many people are not satisfied with their height. That is the reason why they keep asking questions like how to get taller? Is it possible to increase height? How can I grow taller as an adult? Firstly, we should consider a general question - is it possible to increase the height after puberty at all? The conclusion is that after the closure of growth plates, it is not possible to increase bones length.
It means that a human cannot grow taller. However, we can observe slight daily variations in height for most adults. The cause of these changes lies in spinal disc compression through the day. Daily activities impact the disc cartilage, which results in their height reduction.
Note that we are tallest just after night and shortest at the end of a long and active day. The first calculator above is mainly based on this method. Note that it is most applicable to Caucasian children between the ages of 4 and 9 who are free from any growth-related condition or disease.
These growth charts consist of percentile curves illustrating the distribution of specific body measurements of children in the United States. In total, there are 16 charts that contain data that can be used to compare the growth of a child over time. Measurements such as height, weight, and head circumference of a child can be compared to the expected values based on data from these growth charts of children of the same age and sex.
In general, children maintain a fairly constant growth curve, which is why these charts can be used to predict the adult height of a child to a certain extent. There are also some very simple, but less accurate, methods available. One of them is adding 2. The second calculator above is based on this method.
Another simple method is to double the height achieved by the child by age 2 for a boy, or age 18 months for a girl. As mentioned above, very tall parents are more likely to have a taller child, while very short parents are more likely to have a shorter child, with the child being more likely than their parents to be closer to average height.
After the growth spurt during puberty, which differs slightly for girls and boys, neither will typically grow much more, and girls typically stop growing by 15, while boys stop at around 18 years of age.
