To address the issue of facet pain, a potential limiting factor with use of the anterior disc alone, 360 dynamic systems are being considered. The advent of facet replacement technology provides an opportunity to asses the combination of anterior disc with artificial facets to address facet pain. The purpose of this study was to explore the impact such a combination has on the tissues and function of the lumbar spine and each other. To this end a validated finite element (FE) model of the lumbar spine was used to evaluate the biomechanics of an anterior disc arthroplasty with a facet arthroplasty system.
