Zusammenfassung:To evaluate the reproducibility of the AO/Asif classification for humeral shaft fractures. Consecutive radiographs of the arm in both anteroposterior and lateral view from 60 patients with humeral shaft fractures were analyzed. Six observers who were familiar with the AO/Asif classification (three shoulder and elbow surgery specialists and three general orthopedists) were selected to make the analysis, which was done at three different times. The data were subjected to statistical analysis using the kappa coefficient. The intra and interobserver concordance was statistically significant in all the analyses. All the evaluators showed concordance between the three evaluations that was considered to be statistically significant. However, the highest values were found among the specialists. Avaliar a reprodutibilidade da classificação AO/Asif para as fraturas diafisárias do úmero. Foram analisadas radiografias consecutivas em duas incidências (anteroposterior e perfil do braço) de 60 pacientes com fratura do úmero diafisário. Seis observadores familiarizados com a classificação AO/Asif, três especialistas em cirurgia do ombro e cotovelo e três ortopedistas gerais foram selecionados para análise, a qual se deu em três tempos distintos. Os dados foram submetidos à análise estatística com o coeficiente kappa (κ). A concordância intra e interobservadores foi estatisticamente significante em todas as análises. Todos os avaliadores concordam com as três avaliações consideradas estatisticamente significantes. Porém, os maiores valores são encontrados entre os especialistas.
