The spacer supports are disposed between the vertebra-attachment portions, and the lower spacer support is disposed between the bottom vertebra-attachment portion and the upper spacer support. The disc further includes a first elastic spacer positioned between the spacer supports for compressively resisting tensile loading of the disc; and a second spacer disposed between the bottom vertebra-attachment portion and the lower spacer support or between the top vertebra-attachment portion and the upper spacer support for compressively resisting compressive loading of the disc.
