PONZONE, Agustina et al. Comparison between the Pediatric AO Classification  and the Dias-Tachdjian Classification in pediatric ankle fractures. Rev. Asoc. Argent. Ortop. Traumatol. [online]. 2013, vol.78, n.1. ISSN 1852-7434.

Background: The purpose of this study was to analyze the degree of reliability of the two most widely used classification systems for pediatric ankle fractures. Methods: We studied 53 patients (34 boys and 19 girls) with ankle fractures. Two classifications were used. A detailed study was carried out calculating the Cohen's kappa index to measure intraobserver reliability and the kappa value was deduced using the Fleiss method to determine interobserver agreement. Results: The intraobserver and interobserver agreement was not significantly different between the different groups of assessors. Conclusions: In the pediatric age, different types of fractures and different mechanisms within an isolated fracture can be found. We found that many of these fracture pat-terns do not fit in any of the two classifications, which are unproductive to guide treatment selection.
