- See: Multisegmented Hook Instrumentation
- 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;
- 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;
- 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
