Long-term Outcome After Posterolateral, Anterior, and Circumferential Fusion for High-Grade Isthmic Spondylolisthesis in Children and Adolescents

Abstract

The clinical outcome was best in the CF group as measured by ODI. Degenerative changes were most commonly found at the level of the slip and above the fusion level. The prevalence of disc prolapses was low. Spinal fusion for isthmic spondylolysis is not associated with central canal stenosis above the fusion. Radiologic nerve root stenosis was common but asymptomatic. Mild muscle atrophy was common.
