How to tell if a bone is closed, how to tell if a bone is closed

The epiphyseal line is the cartilage line between the epiphysis and the metaphyseal end of the bone, and the epiphyseal line cartilage proliferation, apoptosis, and calcification can promote bone growth. There is no clear indication of epiphyseal line closure, which is more intuitively reflected in the child's slower growth and no obvious growth within 1 year. If you want to close the epiphyseal line, you need to do bone age testing, because the bone age of ordinary people is in boys at the age of age, and girls stop growing after the age of the year, so through the bone age test, the age difference between the age and the age can be roughly judged.

A person's height mainly depends on genetic factors, and reasonable nutrition, exercise, and sleep can effectively promote a person's height. Human growth peaks during adolescence, between the ages of 12 and 14, and gradually slows down after puberty, and gradually stops between the ages of 18 and 20.

It is difficult to judge whether the bone is completely closed, so it is necessary to take an X-ray and have an X-ray examination done in a regular hospital.

1. The bone line is the cartilage between the epiphysis and the metaphysis, which appears as a wide translucent band on X-ray, and the oak gradually becomes shorter with age, and when the cartilage of the epiphysis and metaphysis is completely ossified, a tight slit is formed.

2. At this time, the epiphyseal line is completely closed, and the bone stops growing. To reach your full growth potential, eat plenty of vegetables and high-protein foods, as well as calcium-rich foods and zinc-rich foods. Prevent picky eating, ensure rest time and quality, participate in more physical exercise, and do more jumping and snatching movements.

Is there any way to judge for yourself?

Analysis: It is not possible to accurately determine whether a bone has closed based on physical phenomena and sensations alone.

Human height is determined by the growth and development of bones, bones are divided into diaphysis and epiphysis according to their parts, the cartilage between the epiphysis and the diaphysis is epiphyseal cartilage, epiphyseal cartilage continues to secrete osteoblasts and gradually ossify, bone can continue to grow, and people will grow taller. In adulthood, the epiphyseal cartilage is all ossified, and the backbone and epiphysis are joined together (called epiphyseal closure), and the bone no longer grows, and the person's growth in height stops.

Why does bone age determine growth potential?

Skeletal age, or bone age for short, is the growth cycle of bones, and many people have different biological ages and bone ages.

However, the age of the bones cannot be determined by the naked eye, and the bone age can only be judged by the bone age meter. In general, the wrist is the most ideal, and a large number of long, short and round bones are concentrated here, which reflects the growth and maturation of the bones of the whole body, and the method is simple and the conclusion is accurate.

If the growth cycle of the bone is synchronized with the noisy cluster period of the person's physiological growth cycle, the bone age is normal;

If the bone growth cycle is shorter than the physiological growth cycle, the bone age is older; On the contrary, the bone age is small.

The size of bone age is determined by the degree of bone growth and development of adolescents, and bone age can more accurately reflect the bone growth and height growth potential of people at all ages from birth to full maturity. Bone age is a commonly used clinical test method, which can more accurately reflect the maturity of the body than biological age. It can accurately reflect the child's developmental age and stage of physical development.

Bone age helps to understand a child's height development potential. Suppose there are two 11-year-old girls, both of whom are 145cm in height, and other growth conditions are also the same, but one has the same bone age and biological age; The other has reached the age of 14, which is greater than the biological age, and has menstruation, if the two children are bored and completely rely on natural growth, it can be preliminarily thought that the height of the former child will exceed that of the latter child in the future.

I wish you to grow tall, healthy and happy.

Bone closure refers to a physiological phenomenon in which the epiphysis cartilage at both ends of the long bone merges with the normal bone body. There are usually several small ways to tell if a bone is closed:

1. The degree of depression on both sides of the knee joint: it can be roughly judged by the depression on both sides of the convex bone on the knee joint, if the depression on both sides is larger, it means that it is closed, and if the degree of depression is small, it is not closed;

2. Changes in body shape and height: Teenagers in the period of rapid development are often tall and slender, and the muscles are not developed. When the patient's height gain is slow, muscles are full, and weight is gained, it is considered that the epiphyseal line may be closed.

In addition, if the height has not changed for a long time, it usually means the closure of the epiphysis;

3. Age: Generally, the epiphyseal line is basically closed after the age of 20, but age is not the fundamental basis for judging the closure of the bone line.

The above method is a self-test method for bone closure, which is generally not the final result, and it is recommended to go to a regular hospital for X-ray examination. Through X-rays, the epiphyseal line of the long bone can be intuitively seen, and finally the doctor will give the correct judgment. In daily life, especially in the development period, teenagers can do more sports activities such as high jump, rope skipping or basketball, etc., to ensure that the intake of nutrients is balanced and sufficient, and pay attention to rest on time, which can promote the growth and development of the body.

01 Small ways to judge bone closure: 1. You can see if there are protruding bones above the child's kneecaps, and then look at both sides, if the concave places on both sides are deeper, then the child's bones may be closed. 2. Another very accurate way to determine whether a child's bones are closed is the child's sexual development.

However, the most accurate way is to go to the hospital for a local radiographic examination, and you can accurately determine whether the bone is closed.

Bone closure is a phenomenon that must be experienced in the process of human growth and development, which refers to a phenomenon in which the epiphyseal cartilage at both ends of the human skeleton is fused with the normal bone body. Once the epiphyseal cartilage of the human limb is closed, the limb muscles may gradually become thicker, stronger and stronger, mainly because when the epiphyseal cartilage is not closed, the longitudinal length of the limb will continue to grow and develop, and the muscles around the limb will continue to grow, and its shape will change with the change of limb length.

A small way to determine bone closure.

1. You can see if there are protruding bones above the child's kneecaps, and then look at the two sides If the recesses on both sides are deeper, then the child's bones may be closed. Of course, this method is more earthy, and it is definitely not as accurate as the ** shooting, so in order not to delay the opportunity for the child to grow taller, it is the most important thing to go to the hospital to check whether the bones are closed.

2. It is recommended that parents do bone age for their children every 3-5 years, if the gap is large, then intervention is needed. 0 2-year-old children are in the stage of rapid bone development, and can grow about 25cm in the first year and about 10cm in the second year. Another very accurate way to determine whether a child's bones are closed is the child's sexual development.

For children, precocious puberty is the enlargement of the Adam's apple before the age of nine, and the premature development of the girl's breasts is the characteristic of precocious puberty. Precocious puberty is the key to the closure of children's bones, and with the prosperity of the country, people's living standards have gradually improved, resulting in overnutrition in children, or other reasons, including radiation around us, are the key to precocious puberty in children.

Physical diagnosis – x-rays - to see if the epiphyseal line is closed. If you are over 12 years old, to see if the epiphyseal line is closed, generally speaking, the method of taking the film is to take a positive image of the shoulder, elbow, hand, wrist, hip, ankle and foot.

Of course, sometimes wrist imaging is all the answer.

A few yuan to dozens of yuan for a film, and a few hundred yuan for all the films.

If you are over 22 years old and the epiphyseal line on your wrist has been closed, you will generally not be able to grow taller. If you want to increase your height, you will rely on exercise and nutrition, or you will need surgery.

The epiphyseal line is a layer of cartilage, which is different from the kind of cartilage that does not ossify for life, it is the cartilage used for growth, and one day it will continue to ossify, so that our long bones continue to grow. When the epiphyseal line is closed, it will not grow taller (only consider the long bones), because the long bones will no longer grow, and the legs and arms will no longer be longer.

Epiphyseal line, cross-sectional image of the epiphyseal plate. Between the epiphysis of the long diaphysis and the epiphysis is a disc-like cartilage structure called the epiphyseal plate.

The epiphyseal plate itself is a layer of cartilage. It is a type of cartilage, which is different from the general cartilage that does not ossify for life (such as the cartilage on the ears and nose), but gradually ossifies as it grows.

When the epiphyseal line grows taller, although the epiphyseal plate is gradually ossifying, it is not less (thin) itself, so as to ensure the growth of our long bones, when puberty begins to develop for a period of time, with the secretion of sex hormones, it can be understood that the epiphysis has no ability to continue to grow after gradually ossifying, and after all ossification, there is no longer room and raw materials for growth.

I'll show you the contrast.

Another: The so-called "closed" is an incorrect, folk saying.

The correct description is "loss of epiphyseal cartilage" and "epiphyseal line formation".

This is because, during the growth period, there are cartilage at both ends of the long bones that can transmit X-rays, and the X-rays show a slit "black". When the epiphyseal cartilage gradually ossified, the "suture" that was originally seen on the ** was gone (mistakenly thought that the bone suture was closed), and was replaced by a white line (epiphyseal line formation).

The white line in relative position on your **.

It's the epiphyseal line.
