A visco-elastic motion-limiting artificial intervertebral disc prosthesis
is provided that mimics the physiologic function of a normal spinal disc.
The disc comprises upper and lower endplates having therewithin channels
or openings for optionally receiving one or more motion-limiting members
fitted on each end with an enlarged portion. One or more compression
stops is provided between the upper and lower endplates. Additionally, an
elastomeric cushion is disposed between the endplates and surrounds the
motion-limiting members. Also, force transducers and microelectronics can
be utilized to provide data to the surgeon or the patient regarding the
load state of the disc.
