ABSTRACT:
The subject invention provides a modular six-degrees-of-freedom spatial mechanism for spinal disc prosthesis, with three rotational and three translational degrees-of-freedom within the entire workspace of a Functional Spinal Unit (FSU). The prosthetic disc mechanism attaches to upper and lower plates anchored between vertebrae of an FSU. Scaling, conjoined with motion limit stops, allows the device to realize almost any nominal spinal articulation, from the cervical to lumbar regions.
