Abstract

BACKGROUND: Spondylolisthesis is a common cause of lower back pain, often accompanied by spinal stenosis, disc degeneration, and altered biomechanics. Reduction is achieved anteriorly through anterior lumbar interbody fusion (ALIF) or posteriorly through pedicle screws/rods. ALIF allows for favorable biomechanics for fusion but has limited reduction capability in high-grade slips. Anterior reducti…
