Cotrel Dubousset

The Cotrel Dubouset allows for distraction, compression, and derotation of the scoliotic deformity. In the initial study of patients with Idiopathic Scoliosis treated with the Cotrel Dubousset system, significant reduction of their curvature was achieved. Cotrel-Dubousset instrumentation uses hooks and rods in a cross-linked pattern to realign the spine and redistribute the biomechanical stress.

The main advantage of Cotrel-Dubousset instrumentation is that, because of the extensive cross-linking, the patient may have to wear a cast or brace after surgery. The disadvantage is the complexity of the operation and the number of hooks and cross-links that may fail.
