A method for providing an InVivo model of disc degeneration. The method
includes percutaneously inserting a needle into a non-human surrogate
disc, generally the disc of a rabbit, so that the needle ruptures the
annulus of the disc. Fluoroscopy X-ray images can be used to visualize
the placement of the needle to the proper location. By using the proper
surrogate, rupture of the annulus of the disc will have a quick
degenerative effect on the disc, which can be visualized using MRI or
other suitable imaging devices. By studying the etiologies associated
with disc degeneration of the surrogate, treatments can then be devised
to attempt to reduce the rate of degeneration, reverse degeneration, or
other disc treatment procedures.
