OBJECTIVES: To determine the reliability of the Grewlych-Pyele method in the estimation of bone age in children. METHODS: The design was observational, analytical of repeated measures, diagnostic tests, at the Hospital IV Lazarte - Trujillo, 30 left hand X-rays of children were evaluated, using the Greulych Pyle method, by 3 trained and blinded physicians at two times separated by 1 week, to determine the reliability of the method by inter- and intra-observer variability. RESULTS: The mean chronological age was 10.3 ± 3.11, with 19 (63.3%) being males. The mean bone age in the medical1-medical2-medical3 pair was 10.46 ± 4.09, 10.73 ± 4.62, 10.28 ± 4.02, in the first observation and 10.65 ± 4.13, 12.22 ± 4.43, 10.76 ± 4.17 in the second observation; differences -0.18, -1.48 and -0.48 intraobserver; all less than 10%; although the anova is significant p=0.000; The correlation of the findings is significant with a Pearson of 0.974, 0.854 and 0.979 respectively p=0.000 in the 3 cases. The Cronbach's alpha of the Greulich-Pyle method is of the differences in the means between subjects are always less than 10% intersubject Anova with p=0.000. The Cronbach's alpha coefficient is highly reliable =0.984 and the intraclass correlation is 0.909. Agreement levels are 60%- 50%; 73.3-70%; 46.6%-53.3% between Med1-Med2 (O1-O2), between Med1- Med3(O1-O3) and between Med2-Med3(O2-O3) respectively. The Kappa coefficient of agreement between observers for pathological bone age is 0.437 with p=0.013. CONCLUSIONS: The method Grewlych-Pyle has high fiability to estimate bone age in children
