ABSTRACT Objective: To compare the measurement of the Cobb angle in printed radiographs and digitalized radiographs displayed with the "PixViewer" tool. Methods: Pre-operative radiographs of 23 patients were performed in printed films and using the software "PixViewer". The same evaluator, a spine surgeon, chose the proximal and distal end vertebrae at the limit of the main curve in printed radiographs without identifying patients, and measured the Cobb angle based on these parameters. The same parameters and measurements were performed in digitalized radiographs. The measurements were compared, as well as the choice of end vertebrae. Results: The average change in the Cobb angle between the methods was 1.48±1.73°. The intraclass correlation coefficient (ICC) was 0.99, demonstrating excellent reproducibility. Conclusion: The Cobb method can be used to evaluate scoliosis through the "PixViewer" tool with the same reliability of the classic method on printed radiographs.
