A multiple-state geometry artificial disc assembly attached to vertebrae includes a compliant load bearing spacer element having an upper curved portion and a lower curved portion, a first plate coupled on the upper curved portion of the compliant load bearing spacer element and a second plate coupled on the lower curved portion of the compliant load bearing spacer element. The first plate and the second plate preferably are of a flexible material. The first plate and the second plate transitions from a convex configuration to a concave configuration in-situ in a vertebral disc space. The upper curved portion and the lower curved portion of the compliant load bearing spacer element may include a plurality of openings. The compliant load bearing spacer element may further include a middle cylindrical portion dimensioned and configured to match a gap between the first plate and the second plate.
