Abstract
A spinal fixation device including two plates and a coupling element for coupling the plates in a fixed manner about adjacent spinous processes of the spine. Each plate is preferably equipped with integral spikes on the inwardly facing surfaces for pressing into the spinal processes and thereby augmenting the purchase between the plates and the spinous processes. Each plate contains a central aperture through which the coupling element passes in order to couple the plates together.
