It is not possible to measure bone age at home by yourself. To measure bone age, you need to go to a regular hospital to take an X-ray to observe the development of the bones, and then clarify the bone age. Bone age refers to the age of the bones, which can be measured clinically to observe the growth and development of children and adolescents. If there is a mismatch between the measured bone age and the normal bone age, there may be growth retardation or early growth. In clinical practice, common methods of bone age determination include orthopantomogram of the wrist joint, orthopantomogram or lateral X-ray of the pelvis, and orthopantomogram of the knee joint. Bone age is determined comprehensively by observing the state of bone growth, formation of ossification centers, and epiphyseal closure. To sum up, it is impossible to measure bone age at home, you need to go to a regular hospital for examination, and judge the bone age under the evaluation of a professional doctor.
