A child's current height and bone age can be used to predict adult height. [4] Other uses of bone age measurements include assisting in the diagnosis of medical conditions affecting children, such as constitutional growth delay, precocious puberty, thyroid dysfunction, growth hormone deficiency, and other causes of abnormally short or tall stature.
Charts based on a specific race or ethnicity are not useful because of the growth chart progression can be attributed to socioeconomic factors. [14] WHO launched a revised growth in 2006 chart using children from Ghana, Oman, Norway, Brazil, India and the USA that substantiated the fact that growth is highly dependent on environmental factors.

Over the lifespan of an individual, bone is constantly being reconstructed as specialised cells remove and deposit bone leading to a constant renewal of the bone material. [4] The continuous resorption and deposition leaves gaps in the record of growth and missing bone tissue is a case at any stage of a vertebrate's life cycle; 'complete ...

The Tanner scale (also known as the Tanner stages or sexual maturity rating (SMR)) is a scale of physical development as pre-pubescent children transition into adolescence, and then adulthood. The scale defines physical measurements of development based on external primary and secondary sex characteristics , such as the size of the breasts ...
In 1888 Rollet measured the stature and the lengths of the long bones of 50 male and 50 female French cadavers ranging in age from 24 to 99 years, and presented tables for stature estimation. He determined the average length of the long bones of those who presented the same stature. [6]
Tests of animal bones found nearby suggest that the climate was harsh — comparable to modern-day Siberia. That means humans were having success in an extreme climate some 45,000 years ago.
It is composed of around 270 bones at birth – this total decreases to around 206 bones by adulthood after some bones get fused together. [1] The bone mass in the skeleton makes up about 14% of the total body weight (ca. 10–11 kg for an average person) and reaches maximum mass between the ages of 25 and 30. [2]
