Delayed bone age

Human growth and development can be represented by two "ages", namely the age of life (calendar age) and biological age (bone age). Bone age is an abbreviation of bone age, which is determined by means of specific images of bones in X-ray photography. To understand the bone age of a person, an X-ray film of the wrist of the left hand of the person is usually taken. The doctor observes the development of the ossification center of the palmar phalanx, carpal bone and the lower end of the radius ulna to determine the bone age. Biological age (bone age)-The difference in life age within ± 1 year is called normal development. The difference between biological age (bone age) and living age> 1 year is called developmental advancement (abbreviation: precocious). Biological age (bone age)-the difference in life age is less than 1 year is called developmental retardation (abbreviation: late maturity).
