Height restrictions and development of eight major factors

Growth and development of the two available "age" to indicate that the life of age (calendar age) and biological age (bone age). Bone age is the age referred to as bone, bone in the use of X-ray camera to determine the specific image. Measurement of bone age can understand the skeletal growth and development of the situation. And bone age compared to normal standards, can prompt bone growth and development process has been growing too fast or slow, slow bone age is commonly found in cretinism, Cushing's disease, rickets, chronic malnutrition; found in the bone age advance adrenal hyperplasia or tumor, germ cell And tumors, such as hemophilia. To understand the child's bone age in the case, it is usually taken to the Department of the left wrist X-rays, X-ray observation Zuoshou Zhang phalanx, radius and ulna broken the lower end of the ossification center of development, to determine bone age.
Bone age is the development of the human body to determine the maturity of an important and quantitative indicators of the count, the normal growth of children living with their skeletal age are basically the same age. Bone age may be a reflection of the human body in bone age when completed to a high degree of physical hygiene for up to the end, when the percentage, it can be used to predict bone age children and young adult height. Get online the same time the height and bone age (with X-ray film to judge) can be calculated by the estimated adult height, age, but the small unreliable, as a result of factors, but until puberty is more than credible. As a result, if asked to menstruation can also be a number of long, it was decided at this time of skeletal age. Recently, such as attending a two girls, one 9 months after menarche, bone age is nearly 14 years of age; menarche has another 21 months of their bone age was only 13 years more. Clearly the latter may be room for far longer than the former. In addition, we can also calculate the child's parents is genetic height, bone age and determine a comprehensive estimate of the growth potential of children.
