Claims21
-20. (canceled)
A prosthetic spinal implant configured to articulate in at least two planes, comprising:
- a pair of endplate components operably connected to form an articulating joint, wherein each endplate component comprises a base and an exterior surface adapted to engage with bone.
A prosthetic spinal implant, comprising:
- a first endplate component and a second endplate component that are operably connected to form an articulating joint, wherein each endplate component comprises a base and an exterior surface adapted to engage with bone;
- a connector slot formed along each lateral edge of the second endplate component;
- and
- a pair of flexible connectors with a first flexible connector attaching between the first and second endplate components at a first lateral edge of the prosthetic spinal implant and a second flexible connector attaching between the first and second endplate components at a second lateral edge of the prosthetic spinal implant, wherein a portion of the first flexible connector loops through the connector slot at a first lateral edge of the second endplate component and a portion of the second flexible connector loops through the connector slot at a second lateral edge of the second endplate component.
