Objective: The aim of this study was to determine the intra and interobserver concordance rates of the Waldenström, Catterall and Herring classifications for Legg-Calvé-Perthes disease.
Methods: One hundred radiographs of the pelvis in anteroposterior and Lauenstein views, from patients with this disease, were selected. The radiographs were classified by four physicians with different levels of experience who had previously been given guidance regarding the classifications used, in order to minimize any bias of interpretation.
