Claims17
A prosthetic spinal implant apparatus configured to articulate in at least two planes, comprising:
- a first endplate and a second endplate forming an articulating joint, wherein each endplate has a base with an exterior surface adapted to engage with bone;
- an articulating element attached to an interior surface of the second endplate;
- and
- one or more connector rods extending entirely through the articulating element to connect the first endplate to the second endplate, wherein each of the endplates is formed with apertures configured to receive the connector rods and the connector rods extend through the articulating element from a first lateral side of the prosthetic spinal implant to a second lateral side of the prosthetic spinal implant to connect the first endplate to the second endplate and each of the endplates to the articulating element.

A prosthetic spinal implant apparatus configured to articulate in at least two planes, comprising:
- a first endplate and a second endplate forming an articulating joint, wherein each endplate has a base with an exterior surface adapted to engage with bone;
- an articulating element attached to an interior surface of the second endplate;
- an articulation surface configured on each of an interior surface of the first endplate and an exterior surface the articulating element, wherein the articulation surface of the first endplate is configured to articulate against the articulation surface of the articulating element and the articulation surface of the articulating element is flat;
- and
- one or more connector rods extending through the articulating element to connect the first endplate to the second endplate.

A prosthetic spinal implant apparatus configured to articulate in at least two planes, comprising:
- a first endplate and a second endplate forming an articulating joint, wherein each endplate has a base with an exterior surface adapted to engage with bone;
- an articulating element positioned between the first endplate and the second endplate;
- and
- one or more flexible connector rods extending through the articulating element to connect the first endplate to the second endplate, wherein the connector rods extend through the articulating element from a first lateral side of the prosthetic spinal implant to a second lateral side of the prosthetic spinal implant thereby connecting the first endplate to the second endplate and holding the articulating element in place between the endplates.
