Abstract

An artificial intervertebral disc for implantation in the disc space after the removal of a diseased or damaged cervical intervertebral is described and comprises upper and lower disc portions having a plurality of springs positioned therebetween to yieldably urge the disc portions away from each other. A plurality of spikes extend upwardly from the upper disc portion for engagement with the vertebra thereabove. A plurality of spikes extend downwardly from the lower end of the lower disc portion for engagement with the vertebra therebelow.
