Concordance of SMI and CVMS bone maturation indices in pubertal growth stages – cross-sectional study

In order to verify the concordance of the bone development indices (SMI) estimated on the hand and fist radiograph by the method of Fishman (1982) and the indices of development of the cervical vertebrae (CVMS), estimated on the profile teleradiography by the method of Baccetti (2002), was conducted a cross-sectional study on a group of 150 subjects (89 girls and 61 boys), aged 8-18 years. Based on the existing data in the literature and taking into account the average ages at which the SMI and CVMS stages were reached in the research group, a hypothesis of correspondence between SMI and CVMS stages in the pubertal stages was issued and this hypothesis was statistically verified using the coefficient Cohen k. The obtained results (k = 0.82 for the girls 'group and k = 0.67 for the boys' group) confirm the concordance of the SMI and CVMS indices within the researched group and validate the correspondence hypothesis issued.
