Measure bone age

What is bone age?

Which is too short for all children and adolescents 'hand-wrist' x-rays are taken. This shows us the degree of bone age of the so-called skeletal maturation. Calculated from the date on the calendar age of age. In addition, the effect of hormones and nutrition on the left wrist bone age of the film and understood. Calculated by using the existing atlases of bone age bone age, the child's growth potential than their calendar years, taking into account enables the evaluation of skeletal maturation. Evaluation of bone age, grows up to what size you'll be estimated also helps. Physical development of children born at the same time can be very different from each other. Began to develop, age related changes during adolescence, these differences become more pronounced, the determination of bone age rushes us from here.

Calculate the size of your child

Have an influence in determining the length of the child's mother and father's height. The child has finished growing, the expected length, ie, the target size can be calculated as follows:

For men:

The father's height + (mother's height + 12.5 cm) / 2

For girls:

(The father's height - 12.5 cm) + mother's height / 2

Girls 25 men, 30 cm stretched

Adolescence, the increase in human life, there is the maximum length of the second period.

A new-born child, when he was a length of 74 cm, no. So we think he was born 50 cm, 24 cm length has been increased. Between 1-2 years of age will increase an average of 12 inches height. Then it up to adolescence, children approximately 5-6 inches per year biosynthesized.

Adolescence, girls 20-25, boys 25-30 inches from the biosynthesized. Some of the boys rarely exceed 30 cm height increase.

Rapid increase in size due to the time of puberty in girls increased estrogen, increased testosterone in men.

Estrogen secreted during puberty in girls, a longer length that causes the growth cartilage on the rapidly closing. Therefore, ruled the popular girls between the age is believed to grow in length. But then the girls ruled height increase does not stop, just very slow.

Regular-sized increase in predisposed menses, after the first ruled, but increases around 5-6 inches.
