ABSTRACT Objective: To analyze the anatomic influence of the ribs related to the severity of thoracic spine burst fractures. Methods: A retrospective review of 28 patients with thoracic spine burst fractures hospitalized by the Spine Group of the Hospital Ortopédico de Passo Fundo between January 2002 and December 2016 was conducted. The kyphosis, vertebral collapse, and narrowing of the vertebral canal measurements were compared between patients who had fractures at the true and false rib levels (T1 to T10) and those with fractures at the floating rib levels (T11 to T12). Results: The kyphosis, vertebral collapse, and narrowing of the vertebral canal values, measured only for vertebrae pertaining to the rib cage, were low. In addition, there were no statistically significant differences between the measurements of the group of patients with fractures at the level of the true and false ribs (T1 to T10) and the group of patients whose fractures were at the level of the floating ribs (T11 and T12). Conclusion: The differences between the traumatic structural changes in the vertebrae with true and false ribs (T1 to T10) and the vertebrae with floating ribs (T11 and T12) were not significant in the present study. Level of Evidence II; Retrospective study. RESUMEN Objetivo: Analizar la influencia anatómica de las costillas con respecto a la gravedad de las fracturas de la columna torácica por estallido. Métodos: Se realizó una revisión retrospectiva de 28 pacientes con fractura de columna torácica por estallido, ingresados en el período comprendido entre enero de 2002 y diciembre de 2016 por el Grupo de Columna del Hospital Ortopédico de Passo Fundo. Se compararon las medidas de cifosis, colapso vertebral y estrechamiento del conducto vertebral entre los pacientes que presentaban fracturas a nivel de las costillas verdaderas o falsas (T1 a T10) y aquellos con fracturas a nivel de las costillas flotantes (T11 a T12). Resultados: Los valores de cifosis, colapso vertebral y estrechamiento del conducto vertebral, medidos solamente en las vértebras pertenecientes a la caja torácica, se mostraron bajos. Además, las mediciones no presentaron diferencias estadísticamente significativas al comparar los grupos de pacientes que presentaban fracturas a nivel de las costillas verdaderas o falsas (T1 a T10) con aquellos cuyas fracturas estaban a nivel de las costillas flotantes (T11 a T12). Conclusiones: Las diferencias entre los cambios estructurales traumáticos en las vért
