Abstract

BACKGROUND CONTEXT: Sagittal spinopelvic alignment has been associated with patient-reported outcome measures and mechanical complication rates. Recently, it was claimed that linear numerical values of pelvic tilt and lumbar lordosis measurements may be misleading for patients that have different magnitudes of pelvic incidence. The use of "relative" measurements embedded in a weighted scoring of Global Alignment and Proportion (GAP) was proposed.
