Assessment of bone age in prepubertal healthy Korean children: comparison among the Korean standard bone age chart, Greulich-Pyle method, and Tanner-Whitehouse method.

Kim JR, Lee YS, Yu J - Korean J Radiol (2015)

Bottom Line: The three methods were compared using one-way analysis of variance.Significant correlations were found between chronological age and bone age estimated by all three methods in whole group and in each gender (R(2) ranged from 0.87 to 0.9, p < 0.01).The KS, GP, and TW3 methods show good reliability in the evaluation of bone age of prepubertal healthy Korean children without significant difference between them.

ABSTRACT

Objective: To compare the reliability of the Greulich-Pyle (GP) method, Tanner-Whitehouse 3 (TW3) method and Korean standard bone age chart (KS) in the evaluation of bone age of prepubertal healthy Korean children.

Materials and methods: Left hand-wrist radiographs of 212 prepubertal healthy Korean children aged 7 to 12 years, obtained for the evaluation of the traumatic injury in emergency department, were analyzed by two observers. Bone age was estimated using the GP method, TW3 method and KS, and was calculated in months. The correlation between bone age measured by each method and chronological age of each child was analyzed using Pearson correlation coefficient, scatterplot. The three methods were compared using one-way analysis of variance.

Results: Significant correlations were found between chronological age and bone age estimated by all three methods in whole group and in each gender (R(2) ranged from 0.87 to 0.9, p < 0.01). Although bone age estimated by KS was slightly closer to chronological age than those estimated by the GP and TW3 methods, the difference between three methods was not statistically significant (p > 0.01).

Conclusion: The KS, GP, and TW3 methods show good reliability in the evaluation of bone age of prepubertal healthy Korean children without significant difference between them. Any are useful for evaluation of bone age in prepubertal healthy Korean children.

Figure 1: Correlation between chronological age and bone age measured with Greulich-Pyle (GP) method in whole group and in each gender.

Mentions: The correlations between chronological age and bone age estimated by each method are shown in Figures 1, 2, and 3. There were significant correlations between chronological age and bone age estimated by the three methods in the whole group and each gender (R2 ranged from 0.87 to 0.9, p < 0.01). Table 3 summarizes correlation coefficients between chronological age and bone age measured with each method. In the whole group and the group of girls, correlation coefficient between chronological age and bone age estimated by KS (R2 = 0.89 in the whole group and the group of girls) was slightly higher than others (GP and TW3, R2 = 0.88 in the whole group and 0.87 in the group of girls). In the group of boys, the correlation coefficient between chronological age and bone age estimated by KS and GP (R2 = 0.9) were slightly higher than TW3 (R2 = 0.88). But, according to the result of one-way ANOVA (Table 4), the difference between three methods was not statistically significant in the whole group (p = 0.9) and in each gender (p = 0.34 in boys and 0.29 in girls).
