adult height projection calculation formula and bone age in puberty
Target height in cm for a boy =
[(mother's height in cm + 13) + father's height in cm)]/2
157 + 13= 170
170 + 176 = 346
346 / 2 = 173cm
son's projected height is 173cm, assuming his puberty comes at the normal time
The height projection must be adjusted according to when puberty occurs. Early puberty causes a rapid growth spurt that ends prematurely, causing short height in adulthood.
If the boy's growth spurt and puberty happens early, he will be tall in pubescent years but shorter than projected in adulthood, due to early closure of the bone growth plates.
If the boy's growth spurt and puberty happens late, he will be short in pubescent years but taller than projected in adulthood, due to a prolonged growth period before closure of the bone growth plates.
Growth hormone has no further effect on height once the bone growth plates have closed.
timing of onset of puberty is related more to bone age than to chronologic age.
The earliest triggers of puberty usually start by the time the bone age reaches 12 years of age in boys.
Maturity Assessment by skeletal age
Determination method must be stated along with bone age assessment. The methods most commonly used are the Greulich and Pyle Atlas and the Tanner-Whitehouse (TW2) method. In addition, other methods such as the FELS-method are also available. A result by the Greulich and Pyle method is generally about 1 'year' less than that as assessed by the Tanner-Whitehouse technique. The TW2 system has been transformed recently by the original author into a computerized image analysis system using a continuous scale Computer-Assisted Skeletal Age System: CASAS.
