Abstract
The present invention relates generally to a prosthetic spinal disc for replacing a damaged or degenerated disc between two vertebrae of a spine. The present invention also relates to prosthetic spinal disc designs that have either or both interlocking and magnetic components.
Claims16
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 first flexible connector attaching between the pair of end plate components at a first lateral edge of the prosthetic spinal implant;
- a second flexible connector attaching between the pair of end plate components at a second lateral edge of the prosthetic spinal implant;
- and
- a connector receiving opening entirely set in from a boundary of each lateral edge of a first endplate of the pair of endplates, each of the connector receiving openings comprising,
- a connector slot formed in the exterior surface of the first endplate, and
- a first connector hole and a second connector hole formed in the base of the first endplate, wherein the first connector hole and the second connector hole are separated by a portion of the base.

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 first connector slot formed along and entirely set in from a boundary of a first lateral edge of the second endplate component;
- a second connector slot formed along and entirely set in from a boundary of a second lateral edge of the second endplate component;
- a first flexible connector attaching the first and second endplate components at the first lateral edge of the prosthetic spinal implant, wherein a portion of the first flexible connector loops through a pair of connector holes formed in the first connector slot and the first connector slot encircles the portion of the first flexible connector looping through the first connector slot;
- and
- a second flexible connector attaching the first and second endplate components at the second lateral edge of the prosthetic spinal implant, wherein a portion of the second flexible connector loops through a pair of connector holes formed in the second connector slot and the second connector slot encircles the portion of the second flexible connector looping through the second connector slot.
