What is bone age? What does bone age mean?

Bone age and age are not the same thing. Bone age is an indicator of a child's bone development. For example, the age at which the carpal ossification center appears is roughly as follows:

1-year-old capitate, 2-year-old hook-like bone, 3-year-old triangular bone, 4-year-old age-like bone, 5-year-old scaphoid bone, 6-year-old multi-horned bone, 7-year-old small polygonal bone, 8 14-year-old pea bone developing. If the age is greater than bone age, it means that the child is stunted; If the age is less than bone age, the child's growth potential is small, but this is rare. The bone age of the child can be determined by observing the degree of bone calcification in a certain part of the child's body by observing the degree of bone calcification in a certain part of the child's body, and then comparing it with the local standard bone age,

Bone age refers to the age of the bones. Doctors can usually determine the age of the bone based on an X-ray of the left hand. The bone age of a normal person is the same or very similar to the biological age.

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

Bone age is short for skeletal age and is determined with the help of a specific image of the bone in an X-ray camera. X-rays of the wrist of the left hand are usually taken, and the doctor uses the x-rays to determine the bone age by looking at the degree of development of the ossification center at the lower end of the metacarpal phalanx, carpal bone, and radiula of the left hand.

Human growth and development can be used two"Age"i.e., age of life (calendar age) and biological age (bone age).

The changes in human skeletal development are basically similar, and the development process of each bone has continuity and stages. Bones at different stages have different morphological characteristics, so bone age assessment can more accurately reflect the growth and maturity level of an individual. It not only determines the biological age of the child, but also provides an early understanding of the child's growth and development potential and the trend of sexual maturity through bone age

The determination of bone age can also be used to determine the adult height of children, and the determination of bone age is also very helpful in the diagnosis of some pediatric endocrine diseases. Bone age was first used in medical studies to measure the growth and development of children, and then it was widely used to determine the actual age of athletes to determine eligibility. Bone age identification methods are more widely used in the judicial adjudication process and play a very important role.

This is determined with the help of a specific image of the bone in an X-ray camera. When understanding a person's bone age, an X-ray of the wrist of the left hand is usually taken, and the doctor observes the development of the ossification center at the lower end of the metacarpal phalanx, carpal bone and radiula of the left hand to determine the bone age.

Abnormalities in bone age are often an aspect of certain endocrine disorders in pediatrics. Many diseases will affect bone development, or make it advance or make it backward, such as adrenal hyperplasia or tumors, Alreb-ERT syndrome, precocious puberty, hyperthyroidism, ovarian granulosa cell tumor, etc., which will lead to early bone age; Ovarian hypoplasia (Turner syndrome), achondroplasia, hypothyroidism, etc., will lead to a significant backwardness in bone age.
