Effect of Nucleotomy and Hydrogel Implant on Disc Mechanics

My research is to quantify the mechanical effects of removing the nucleus pulposus and of treating the disc with a hydrogel  implant. In one test, the samples undergo 10,000 cycles of compressive loading followed by hydrated recovery. In another, samples are incrementally loaded and then scanned using MRI to evaluate internal disc strains.
