Analysis of Sagittal Balance of Ankylosing Spondylitis Using Spinopelvic Parameters

Abstract

AS patients and normal controls were found to be significantly different in terms of sagittal spinopelvic parameters. Significant relationships were found between sagittal spinopelvic parameters in AS patients. Pelvic tilt was a significant parameter in determination of sagittal balance in AS patient. Furthermore, VAS scores were significantly related to sagittal spinal parameters which were closely related with pelvic orientation in AS patients.
