Cotrel-Dubousset



- See: Multisegmented Hook Instrumentation

- Discussion:
    - are excellent for the treatment of thoracic or thoracolumbar frx;
    - these rods can be used with hooks and/or screws;
    - if hooks are used, do not place them adjacent to any area of canal comprimise;
    - because rods are very flexible, this system may not be sufficiently rigid to maintain sagittal plane correction in larger individuals;
    - because the rods can be used with screws, they are excellent, esp when trying to instrument as short an area as possible;

- Sciolosis:
    - w/ a mobile lumbar or thoracolumbar curve, CD instrumentation can provide permanent derotation and restoration of lumbar lordosis 
          and thoracic kyphosis;
          - in other words there is improved saggital plane correction;
    - indications:
          - single thoracic curve (method of choice);
          - especially indicated if thoracic spine is hypokyphotic;
          - in the study by Lenke et al 1998, on average preoperative Cobb angles were 53 deg and postoperatively, the average Cobb 
                angle was down to 28 deg;
          - indicated for treatment of double curves and lumbar curves because it may  restore & preserve the sagittal contour;
    - post op:
          - no bracing is needed for adolescents;
          - bracing is indicated in adults w/ thoracolumbar, lumbar, or double curve
