Bone Age Inspection
The key to growth in stature lies in the growing condition of bones and whether the growth plate, also known as epiphyseal plate, is closed. Epiphyseal closure indicates that the bones stop growing and human body stops gaining height. So far, bone age study is the most common method used to compare ages and evaluate bone maturity.

Bone age study is to take X-ray films of left palm and wrist, and then calculate current bone age according to the state of bone, growth, and epiphyseal closure show on the films to predict body height upon adulthood and diagnose endocrine disease. Evaluation methods are different between male and female.
