The Hip: Preservation, Replacement and Revision

Pedicle Screw Implants for Burst Fractures


- Discussion: 
- allow control of Anterior column via a posterior approach; 
- provide 4 point fixation; 
- reduce the number of levels that must be incorporated in the construct; 
- this is a particular adavantage in the lower lumbar spine; 
- screws provide lever arms, which facilitate reduction maneuvers and allow lordosis to be maintained; 
- allows saggital plane correction; 
- because limitations are imposed by pedicle diameter, these systems are best used for L2 to L5 levels
