Abstract
The present invention relates to a spinal fixation system. The system comprises a screw for pivotally attaching a bolt to a vertebrae to be treated. A pivot block is threaded onto the bolt to move the pivot block up and down the bolt. A rod is secured at each of its ends to vertebrae on either side of the vertebrae to be treated and a clamp block is attached to the rod and the pivot block to thereby allow the pivot block to push, pull or rotate the vertebrae to be treated.
