Is the Cotrel-Dubousset Really Universal in the Surgical Treatment of Idiopathic Scoliosis?

We reviewed the results of 22 cases of Cotrel-Dubousset (C-D) instrumentation, 16 cases of anterior approach, and 200 cases of posterior approach by Harrington instrumentation and modifications of Harrington procedure. Posterior spinal fusion and instrumentation by C-D gives better correction and stabilization in thoracic and balanced double major curves. We no longer use the Harrington procedure and its modification. In lumbar and short thoracolumbar curves, VDS is still preferred. In some double major curves combined procedures, VDS and C-D are used to obtain more correction with a shorter fusion area.
