The artificial intervertebral disc is preferablydesigned to restore disc height and natural disc curvature, allow for anatural range of motion, absorb shock and provide resistance to motion andaxial compression. Furthermore, the intervertebral disc may be used in thecervical, the thoracic, or the lumbar regions of the spine. The artificialintervertebral disc may include either singularly or in combination: aninterior including at least one spring member preferably incorporating aarcuate surface member, a flexible core, the flexible core preferably being aslotted core, a ring spring, a winged leaf spring, or a leaf spring, or.
