"There are several methods to measure the pelvic obliquity angle, with the Maloney and Osebold method considered the most reliable 4."
"On a PA spine x-ray, a line is drawn across the superior iliac crest, and a second line is drawn perpendicularly. A third line is drawn connecting the centre of T1 to the centre of S1, and pelvic obliquity is measured as the angle between the second and third lines 4."
"On a PA spine x-ray, a line is drawn across the superior iliac crest, and a second line is drawn parallel to the lower end of the x-ray. Pelvic obliquity is measured as the angle between the first and second lines 4,6."
"Pelvic obliquity is a potential source of measurement error on cross-sectional imaging, especially for measurements conducted on axial images if not considered and appropriately corrected by reformatting true axial planes 3."

"On erect x-rays, pelvic obliquity manifests as a lateral tilt of the pelvis 7. Pelvic obliquity has been commonly measured as an angle, although some methods measure pelvic obliquity as a distance; there is no gold standard for measuring pelvic obliquity 5,8."
