Bone age and height, how many years is the biggest difference between bone age and chronological age

Listen to the authorities, which have been studied by scientists.

Male: (father's height + mother's height).

Female: (Mother's height + father's height.)

If the epiphysis is not completely closed, it can still grow.

Not necessarily accurate, afraid that you can't grow tall, you can do more exercise, in addition to genetics, acquired exercise also has a great impact on height.

Not necessarily accurate, I also sideways, saying that I can only 175, but now it is 182, the landlord does not have to worry, drink more milk, eat vegetables, practice more horizontal bars, and make you grow taller! Hehe.

Let's give you a formula for calculating your height first.

Son's adult height (cm) (father's height, mother's height) Error + -3cm, daughter's adult height (cm) (father's height, mother's height) 2 Error + -3cm, according to the above calculation, that is, your height has a chance to be higher than 170, but there are many factors that depend on the day after tomorrow, that is, your personal factors.

For example, physical activity and nutrient intake are very important.

You're still growing a lot of your age, and it's not hard to get to 170 or more.

As for what you said about bone age testing, the accuracy is not necessarily high, and I personally think that it is comparable to those EQ tests that we are usually exposed to, so it is better not to be too gullible about those.

During the first period of growth and development, eating more protein foods is helpful for the growth and development of the body. In addition, exercising more can help your child's bones grow. So,Does growing taller depend on bone age?

Growing taller is mainly the growth and ossification of cartilage, and when the bones are completely ossified, people will basically not grow taller anymore, so I will introduce them to you.

Does growing taller depend on bone age There is no doubt that I believe that all parents want their children to be healthy and healthy, boys are tall and big, and girls are slim. What many parents don't know is that in the stage of a child's growth, his growth and development is not only expressed by the age of the calendar, that is, the biological age, but also a more important term for growth and development, that is, bone age, referred to as bone age.

Experts say that the growth of a child's height is not only based on the biological age of the person, but more importantly depends on the growth of bone age. So what exactly is skeletal age? Bone age, that is, bone age, has long been considered a particularly important indicator to measure the growth of human bones and the maturity of the human body in China and abroad, in short, bone age is a ruler to measure the growth and development of the human body.

What is the relationship between bone age and the height of the child? Experts have also explained this, because the growth of human height is in a certain period of time, and the determination of the child's height is the bone growth area in the human body, that is, the epiphysis, before the epiphysis is not closed, the child's height as long as it is through scientific and reasonable means, can promote its growth space, but if the epiphysis is closed, the child's height will be finalized, and all efforts will be useless. Therefore, measuring a child's bone age to understand their potential for growth and development can also help diagnose some pediatric diseases.

How can children grow taller If you want to promote your child's growth, a nutritious diet is the key, so what can your child eat to grow taller? Let me introduce it to you.

Milk: Milk is nutritious, easy to digest and absorb, inexpensive, easy to eat, is "the closest to perfect food", known as "white blood", is the most ideal natural food, it has the original nutrition is incomparable to any other artificial nutrition.

Carrots: Carrots are a crisp, delicious, and nutritious home-cooked vegetable, known as "little ginseng". Carrots are rich in sugars, fats, volatile oils, carotene, vitamin A, vitamin B1, vitamin B2, anthocyanins, calcium, iron and other nutrients.

Oranges: Citrus fruits are nutritious, excellent in color and flavor, and can be eaten fresh and processed into various processed products based on fruit juice. The production of citrus ranks first among all fruits, and citrus juice accounts for 3 4 percent of the juice, which is widely favored by consumers.

Bone age is not the same thing as age.

Usually when we talk about age, we mean chronological age, also known as chronological age.

Bone age is the abbreviation of bone age, which is a kind of developmental age obtained by comparing the actual degree of bone development (calcification) of children and adolescents with the standard degree of development, which can more accurately reflect the maturity of the body than the actual age. Bone age is an important indicator in terms of growth and development, diagnosis and treatment of developmental disorders, growth period and adult height of children. Bone age is largely a representation of a child's true level of development, and is determined by looking at the degree of bone calcification in a certain part of the child's body and comparing it with a standard bone age film.

There are many bone parts used to determine bone age, such as shoulders, elbows, ankles, wrists, pelvis, etc., but wrists are the most commonly used. Because there are 27 bone development markers in the wrist for observation and analysis, and there are bones of various shapes such as long bones, short bones, irregular bones, and round bones, which can better reflect the maturity of the bones of the whole body.

In addition, the filming method is simple and easy to be accepted by children. Therefore, the wrist (usually the left hand) is the most commonly used part of the photograph.

CHN Law. X-ray of the wrist bone: the five fingers of the left hand are separated, the palm of the hand is pressed downward against the X-ray box, the hand is straight and the forearm is straight, and the X-ray lens is aimed at the third metacarpal bone, about 90 cm from the back of the hand. In addition to the whole hand and carpal bones, the x-ray should also include 3-4 cm at the distal end of the radius (the CHN law stipulates that the left hand is patted, and the United States has studied the bone age of 450 people on the left and right hands, of which only 13 people have inconsistent bone ages, accounting for.

Assessment: A total of 14 bones were assessed by the CHN method. Namely:

Radius, 1,3,5 metacarpals, 1,3,5 proximal phalanges, 3,5 middle phalanxes, 1,3,5 distal phalanxes, capitates, hooks. Among them, the radius is divided into 10 grades, the capitate is divided into 7 grades, and the remaining 12 bones are divided into 8 grades. Each bone has a different score for different grades, and the bone age can be assessed by adding the scores of the 14 bones and looking up the table again.

Now, using the computerized assessment software, the computer will automatically determine the bone age by simply entering the grade of each bone. After systematic training and repeated practice, the error of evaluating the film by the CHN method is not large.

Introduction to the process of bone development: (take the radius as an example).

In newborns, the epiphysis part is still cartilage, and later with age, ossification centers begin to appear, and the ossification centers gradually grow, develop to different stages, and take on different shapes, and finally, the epiphyseal part is completely ossified and fused with the backbone. When assessing bone age, the ossification center develops into different shapes as the basis for classifying bone development.

Before ossification, the part of the epiphysis seen on x-rays is transparent.

Bone age is short for bone age, and it is the most useful indicator of the maturity of the human body. It largely represents the level of individual biological development, reflecting the growth potential consumed by height gains.

By the time a person reaches adulthood, skeletal development is complete and the height is no longer increasing, indicating that the growth potential of the height has been exhausted.

Advancing or lagging in bone age relative to chronological age can determine the type of growth a child hasTo adult height, menarche, body type of girland so on.

Therefore, bone age detection and assessment has a wide range of uses in clinical medicine, and many affect children's growthDiagnosis, differential diagnosis and efficacy observation of developmental diseasesBone age should be routinely checked for children who are stunted or growing too fast.

Bone age is determined based on the specific image of the bone in the X-ray camera. The left hand is usually used as the shooting area. Under normal circumstances, the bone age is basically consistent with the actual age, and the difference is not more than 1 year.

Bone age greater than 1 year but not more than 2 years old is considered early;

Bone age is less than 1 year old but not more than 2 years old;

If the bone age is more than 2 years behind the age, the bone age is considered abnormally backward;

If the bone age is more than 2 years earlier, the bone age is considered to be abnormally advanced.

In general, the difference between bone age and age of medium-sized children is usually less than 1 year; In taller children, bone age is often more than 1 year of age; In children with short stature, bone age often lags behind age by more than 1 year.

If the bone age and height are both at the lower end of the standard, that is, the bone age is backward and the child is short, the child is considered to be late development, but can grow into a normal height in the future.

Children with a backward bone age and medium or high height may be tall in the future;

Those who have an early bone age and are short are likely to become short in the future;

Children whose bone age and height are both at the high threshold are early developments, and their growth potential is not great, and they may not eventually grow into tall people.

Therefore, it is advisable to have bone age checked for children around puberty, especially those with a tendency to develop early.

However, it is important to emphasize that not every child needs to have bone age checked, especially for children under 6 years of age, and bone age should only be checked if the child is significantly stunted or growing too fast.
