Introduction
Height growth assessment generally requires evaluating both R bone age and C bone age. According to the TW3 bone age evaluation method, bone age is divided into R bone age and C bone age: R bone age refers to the skeletal age of the metacarpal and phalangeal bones, while C bone age refers to that of the carpal bones. The development of these two regions is influenced separately by sex hormones and growth hormone; therefore, in assessing bone age, both R bone age and C bone age should be considered.
Height growth potential generally depends on both the R bone age and the C bone age.
In the TW3 bone age assessment method, bone age is divided into R bone age and C bone age. R bone age refers to the skeletal maturity of the metacarpals and phalanges (hand and finger bones), while C bone age refers to the carpal bones (wrist bones). The development of these two areas is influenced separately by sex hormones and growth hormones. Therefore, a comprehensive evaluation of both R and C bone ages is necessary to determine whether a child still has potential for further height growth. Normally, bone age does not differ from chronological age by more than one year, so a child's actual age can also serve as a reference for assessing bone age. If a child shows obvious developmental abnormalities, it is recommended to visit a reputable hospital for evaluations including bone age, endocrine function, and overall physical examination, to identify the underlying cause and receive targeted treatment.
During a child’s growth and development period, it is advisable to regularly monitor their development, ensure adequate nutritional intake, and encourage regular physical exercise to promote height growth. Early detection and early intervention are essential to prevent premature closure of the growth plates, which would limit further height increase.
