A retrospective analysis of data collected prospectively in an adult spine deformity multicenter database. ⋯ Roussouly four-type sagittal shape classification could be applied to AS patients. AS modified the theoretical type in one of every three patients. No particular association was found between the sagittal types and specific coronal deformities. Sagittal shape recognition in patients with AS will help restore the appropriate theoretical shape through surgery, which can eventually lead to better surgical outcomesLevel of Evidence: 2.
