Mid- to Long-Term Outcomes in Adolescent Idiopathic Scoliosis After Instrumented Posterior Spinal Fusion

This study confirms the negative effect of Harrington rods on sagittal alignment. We further found that the degree of correction in the coronal and sagittal planes was higher after Cotrel-Dubousset instrumentation than all-pedicle screw fixation. All-pedicle screw constructs offered the lower risk of mid- to long-term complications and revision surgery.
