Imaging analysis of adjacent segment disease combined with retrolisthesis after posterior lumbar interbody fusion: a preliminary cross-sectional comparative study.

ABSTRACT:

Background

Adjacent segment disease (ASD) combined with retrolisthesis of the adjacent vertebrae is a common radiological phenomenon. However, its characteristics remain unclarified. This study aimed to investigate the epidemiology of ASD with retrolisthesis, preliminarily analyze its radiological features, and identify its risk factors.

Methods

The diagnostic criteria for symptomatic ASD were defined as the recurrence of radiating lower limb pain after the initial surgery and radiological evidence of degeneration at the adjacent fused segment indicating revision surgery. Retrolisthesis in ASD was defined as a ≥3 mm posterior slip of the superior vertebra of the affected segment on a lateral X-ray, no-slip status as the absence of anterior or posterior slippage of the superi
