Aim: The aim of this study was to determine the correlation between the skeletal maturation stages of a hand-wrist method and a cervical vertebrae method in a Peruvian population. Materials and Methods: A descriptive, analytical, retro-prospective, and cross-sectional study was performed. A total of 584 radiographs were analyzed, 292 lateral and 292 hand-wrist radiographs of 7-18-year-old patients from Lima, Peru. Bone maturation was assessed using Fishman's hand-wrist method and Hassel and Farman's cervical vertebral method. To determine the correlation between both methods, Kendall's tau-b, Kendall's tau-c, gamma, and Spearman's rho coefficients were performed. Significance level was set at 5%. Results: Strong and positive correlations were found among the stages studied by both methods; coefficients of 0.751, 0.746, 0.874, and 0.860 for Kendall's tau-b, Kendall's tau-c, gamma, and Spearman's rho, respectively, were found. At the same order, the coefficients for females were 0.761, 0.751, 0.884, and 0.865, while for males were 0.715, 0.687, 0.850, and 0.817. Conclusion: Strong correlation between the skeletal maturity stages by Fishman's hand-wrist method and Hassel and Farman's cervical vertebrae method in the sample studied was found. The correlation was slightly upper in women than men.
