Zusammenfassung:ABSTRACT Objectives: Evaluate the reliability and reproducibility of the kyphosis measurement in thoracolumbar spine traumatic fractures by different assessment methods in different types of fractures. Methods: Fifteen fractures of the thoracolumbar spine, previously classified into types A, B, and C according to Magerl’s classification, were evaluated. The value of kyphosis was measured using five different methods: (1) Cobb angle; (2) Gardner’s method; (3) back wall method; (4) angle of adjacent endplates; and (5) wedge angle. The measurements were performed by five independent observers and repeated five times with a minimum interval of two weeks between each evaluation. Results: Intraobserver reliability was excellent among the five observers, evidencing good reproducibility of the methods. The five methods used also showed great intraobserver reliability in the global analysis, with methods one and four being more consistent. Conclusion: Although there is no universal agreement on measuring kyphosis in thoracolumbar fractures, our study concluded that method 1 (Cobb angle) and method 4 (adjacent endplate angle) presented the best interobserver reliabilities. Furthermore, the use of digitized radiographs and a simple computer program allowed the performance of highly reliable and reproducible measurements by all methods, given the high intraobserver reliability.

Resumo: Objetivos: Avaliar a confiabilidade e reprodutibilidade da mensuração da cifose nas fraturas traumáticas da coluna toracolombar por diferentes métodos de avaliação nos diferentes tipos de fraturas. Métodos: Foram avaliadas 15 fraturas na coluna toracolombar previamente classificadas em tipo A, B e C de acordo com a classificação de Magerl. Em cada caso, foi medido o valor da cifose através de cinco diferentes métodos: (1) ângulo de Cobb; (2) método de Gardner; (3) método das paredes posteriores; (4) ângulo das placas terminais adjacentes; e (5) ângulo de cunha. As mensurações foram realizadas por cinco avaliadores independentes e repetidas cinco vezes com intervalo mínimo de duas semanas entre cada avaliação. Resultados: A confiabilidade intraobservador mostrou-se excelente entre os cinco avaliadores, evidenciando boa reprodutibilidade dos métodos. Os cinco métodos utilizados também apresentaram grande confiabilidade intraobservador na análise global, sendo mais consistentes o método 1 e o método 4. Conclusão: Apesar de não haver concordância uni
