The characteristics of spinopelvic sagittal alignment in patients with lumbar disc degenerative diseases

摘要

PurposeA comparative study of the spinopelvic sagittal alignment in patients with lumbar disc degeneration or herniation (LDD/LDH) in normal population was designed to analyse the role of sagittal anatomical parameter (pelvic incidence, PI) and positional parameters in the pathogenesis and development of the disease. Several comparative studies of these patients with asymptomatic controls have been done. However, in previous studies without lumbar MRI, a certain number of asymptomatic LDD patients should have been included in the control group and then impacted on the results.
