Abstract

A spinal implant for insertion between adjacent vertebrae to function as a disc prosthesis. The prosthesis is formed from two plates fastened to adjacent vertebrae facing each other. The facing sides of the plates have a donut shaped cushioning coupler to replicate the displaced disc material. Stabilizing links are positioned along the edge of the plates to prevent over compression of the shaped cushioning coupler in a bending moment. Adjustable mounting brackets are used to secure the implant to the spine.

Claims (10)

1. A spinal implant comprising: an upper endplate having an upper surface with a mounting receptacle formed in said upper surface positioned longitudinally and another mounting receptacle formed perpendicular thereto intersecting the upper mounting receptacle, said upper endplate having a upper mounting bracket formed from a first elongated planar body with at least one sharp protuberance disposed on the planar body, the planar body having a first end for sliding into one of the upper endplate mounting receptacles and at least one aperture for receipt of a set screw to secure said upper mounting bracket in a fixed position within said mounting receptacle, and said upper endplate having an inwardly facing surface with multiple recesses, a lower endplate forming a mirror image of said upper endplate defined by a lower surface having one mounting receptacle positioned longitudinally and a second mounting receptacle formed perpendicular thereto intersecting the lower mounting receptacle, said lower endplate having a lower mounting bracket formed from a second elongated planar body with at least one sharp protuberance disposed on the second elongated planar body, the second elongated planar body having a first end for sliding into one of the lower endplate mounting receptacles with at least one aperture for receipt of a set screw for securing the lower mounting bracket in a fixed position within said mounting receptacle, and said lower endplate having an inwardly facing surface with multiple recesses, stabilizing linkers constructed of a resilient material with a fibrous laminate skeleton having a first end positioned within the upper endplate recess detachably secured thereto by a first plurality of pins extending through the skeleton and a lower end positioned within the lower endplate recess detachably secured thereto by a second plurality of pins extending through the skeleton; and a cushioning coupler positioned within a space defined by the stabilizing linkers and said inwardly facing surfaces; wherein said spinal implant is configured to be placed within an intervertebral space and configured to be secured thereto.

2. The spinal implant of claim 1 , wherein the upper and lower endplates comprise a planar surface having recesses which form said mounting receptacles and rounded or curved edges along a perimeter of each of said endplate.

3. The spinal implant of claim 1 , wherein the inward facing surface has a shaped body, the shaped body comprising a convex dome, a concave dome, a shaped protuberance, or a recess.

4. The spinal implant of claim 3 , wherein the pins are inserted into one or more holes, tunneled horizontally through each plate through to the slot, and aligned with a pin receiving aperture in the stabilizing linkers.

5. The spinal implant of claim 1 , wherein the stabilizing linkers are block shaped having: planar, curved, concave or a convex surface.

6. The spinal implant of claim 1 , wherein the cushioning coupler is removable, and is shaped and dimensioned for disposition between the upper and lower endplates, within the confines of the stabilizing linkers disposed along a periphery of the upper and lower endplates, said pin extending through the skeleton of said linkers and extending into the endplate.

7. The spinal implant of claim 6 , wherein the cushioning coupler comprises a doughnut or toroid shape, square shape, spherical shape, oval or elliptical shape.

8. The spinal implant of claim 6 , wherein the cushioning coupler is toroid shape.

9. The spinal implant of claim 6 , wherein the cushioning coupler is fillable with volumetric fluids selected from the group of: saline, gels, latex, polymers, polyethylenes, silicones, polyurethanes, collagen, or hydrogels.

10. The spinal implant of claim 6 , wherein the cushioning coupler is a compressible elastic body.
