An artificial intervertebral disc with shock absorption includes upper and lower plates disposed about a shock absorbing movable core. The upper and lower plates have an outer surface which engages a vertebrae and an inner bearing surface. The shock absorbing core includes a unitary member of a rigid material having at least one lateral cut between upper and lower surfaces of the core to allow the upper and lower surfaces to move resiliently toward and away from each other. This allows the core to absorb forces applied to it by the vertebrae.
