Abstract
A number of spinal stabilization devices are disclosed for aligning and fixing vertebrae during surgery, e.g. to facilitate accurate placement of pedicle screws. One stabilization device includes a pair of spiked rails biased to clamp shut and thereby passively engage a number of vertebrae. Another stabilization device includes a tie-rod that connects two or more fiducial markers, each of which is connected to a vertebra, to stabilize the vertebrae including and between each vertebra to which the markers are attached.
