Purpose : The determination of skeletal age is important for the analysis of growth and growth disorders in children. The aim of this study is to investigate the difference of bone age comparing Greulich-Pyle (GP) and Tanner Whitehouse (TW3) methods. We also evaluated the reproducibility of results of each method by different observers (interobserver variation) and by same observer (intraobserver variation). Methods : Bone ages were assessed from left hand-wrist radiographs of 200 children (108 males and 92 females) aged 7 to 15 years by GP and TW3 methods. To evaluate the reproducibility of each method, 102 radiographs were assessed independently by three observers and 100 radiographs were reassessed by one same observer using both methods. Results : The average bone age by GP and TW3 were 10.65±2.24 years and 10.48±2.18 years, respectively (P<0.01). There is significant correlation between GP and TW3 methods (R2=0.94, P<0.01). The interobserver variation of GP and TW3 was not different significantly (0.51±0.44 years by GP vs 0.54±0.42 years by TW3). The intraobserver variation also was not different significantly (0.48±0.44 years by GP vs 0.45±0.37 years by TW3). Conclusion : Our data indicate that bone age by TW3 method was slightly younger than that by GP method but similar, and the reproducibility of both methods were not different. Therefore, both GP and TW3 methods are useful for estimation of bone age in Korea children.
