An Experimental Model of Adult-Onset Slip Progression in Isthmic Spondylolisthesis

Abstract

Spondylolisthesis is defined as a slippage of a vertebral body on the one below. Isthmic spondylolisthesis, caused by stress fracture or a developmental anomaly at the pars interarticularis, is the most common type of lumbar spondylolisthesis with a 6% incidence in adults. Isthmic lumbar spondylolisthesis is a frequent cause of disabling low-back and leg pain. The goal of this study is to improve the quality of treatment of these patients.
