RUS Skeletal Maturity Of Children in urban area in Korea  

Objective

The Tanner-Whitehouse(TW) system is the method of choice for skeletal maturity assessment in both clinical practice and auxological research(Tanner et al. 1983), and it has been used to estimate skeletal maturity in groups of children from all over the world. This study aimed on analyzing the characteristic of the RUS maturity of Korea children by evaluating RUS maturity of Korea children using the TW3 method, compared with Beijing, China & Tokyo, Japan.

Method

Left hand including wrist radiographs of normal children (643 boys and 837 girls) who had visited several local clinics & one University hospital were obtained in 5 cities (Seoul, Busan, Incheon, Suwon, Ilsan). Their RUS maturity was estimated using the TW3 method and 50th percentiles of the RUS scores classified by sex & age were compared with TW3 standards and study results of Beijing and Tokyo.

Result

The RUS maturity of Korea children was similar to the TW3 standard until the age of 12 years in boys and 9 years in girls. The age of full maturity was 16 year-old in boys and 15 year-old in girls.

Fig.1. RUS maturity curves of the Korean boys , and Beijing  and Tokyo  and TW3 Standards. RUS maturity curves of Korean boys  was similar to the TW3 until  age12 years, then had accelerated. The age of full maturity was 16 years, that was faster than 1 year in the TW 3. Full skeletal maturity was reached at the same age, 16 years, advanced when compared with the TW3 Standard.
