Twenty-six patients who underwent Wisconsin instrumentation and 36 patients who underwent Cotrel-Dubousset instrumentation (CDI) for idiopathic scoliosis were studied. Inclusion in the study required at least 24-month follow-up. Variables compared included operating time, blood loss, frontal plane correction, axial and sagittal plane changes, effects on compensation, and complications. In general, operating time, blood loss, and instrumentation problems were greater with CDI. Thoracic curve correction in King II curves was better with CDI. There was no advantage to either system with respect to sagittal plane alignment or rotation. When all factors were considered, a significant advantage to use of CDI could not be demonstrated.
