ABSTRACT:
An artificial lumbar disc made of three components which are inserted individually. Two bean shaped implants are a mirror image of each other and are designed to be inserted on each side of the disc cavity. The third component is designed to fill the disc cavity remaining after the first two components have been inserted. The unique design focuses on restoring the natural function of the disc, reestablishing a preferred disc space, and providing ease of insertion through both a posterior and anterior approach. Moreover, the potential of prosthesis failure is fully addressed and feasible solutions to such an occurrence are proposed.
