Association Between Facet Joint Orientation and Degenerative Spondylolisthesis: A Radiological Study of Double-Level Versus Single-Level Degenerative Spondylolisthesis.

ABSTRACT:

Objective

To evaluate the correlation between lumbar degenerative spondylolisthesis (LDS) and facet joint orientation, and to examine the factors influencing facet joint orientation in patients with double-level LDS (dLDS).

Methods

A total of 40 patients with L3-5 dLDS (mean age, 64.1 years) and 106 patients with L4-5 single-level LDS (sLDS; mean age, 63.5 years) were included. Besides, 100 age-matched healthy participants were recruited as the control group. Facet joint angles at each level from L2-3 to L5-S1 were measured on axial computed tomogrpahy images. Slippage and spinopelvic sagittal parameters were measured using lateral full-spine x-rays.

Results

Both dLDS and sLDS groups had significantly larger facet joint angles from L2-3 to L5-S1 than those in the cont
