Hybrid intervertebral disc system
First Claim
1. A vertebral implant for interposition between two vertebral endplates comprising:
- a first endplate assembly for engaging a first vertebral endplate;
a second endplate assembly for engaging a second vertebral endplate; and
a first flexible core component interposed between the first and second endplate assemblies, the first flexible core component comprising a first end portion and a second end portion, wherein the first end portion is coupled to the first endplate assembly to limit translation of the first end portion with respect to the first endplate assembly and wherein the second end portion is pivotable with respect to the second endplate assembly.

Abstract
A vertebral implant for interposition between two vertebral endplates comprises a first endplate assembly for engaging a first vertebral endplate, a second endplate assembly for engaging a second vertebral endplate, and a first flexible core component interposed between the first and second endplate assemblies. The first flexible core component comprises first and second end portions. The first end portion is coupled to the first endplate assembly to prevent translation of the first end portion with respect to the first endplate assembly, and the second end portion is pivotable with respect to the second endplate assembly.

52. A method for installing an intervertebral prosthesis between a first vertebral endplate and a second vertebral endplate, the method comprising:
- attaching a core component to a first endplate assembly, the core component comprising a hardened articulating surface and a flexible portion;
providing a second endplate assembly comprising a smooth inner surface;
positioning the hardened articulating surface-of the core component proximate to the smooth inner surface of the second endplate assembly;
engaging the first endplate assembly with the first vertebral endplate; and
engaging the second endplate assembly with the second vertebral endplate, wherein the core component engages a groove in the first endplate assembly and wherein the first endplate assembly is rotatable with respect to the second endplate assembly.
- attaching a core component to a first endplate assembly, the core component comprising a hardened articulating surface and a flexible portion;
-
53. A vertebral implant for interposition between two vertebral endplates comprising:
-
a first endplate assembly for engaging a first vertebral endplate;
a second endplate assembly for engaging a second vertebral endplate; and
a first flexible core component interposed between the first and second endplate assemblies, the first flexible core component comprising an outer surface, wherein the outer surface comprises an articulating surface, the articulating surface covering less than the entire outer surface, and wherein the first endplate assembly comprises a coupling mechanism shaped to match a contour of the first flexible core component. - View Dependent Claims (54, 55, 56, 57)

58. A vertebral implant for interposition between two vertebral endplates, the vertebral implant comprising:
-
a first endplate assembly comprising a first vertebral endplate contact surface and a first interior surface;
a second endplate assembly comprising a second vertebral endplate contact surface and a second interior surface;
a flexible core component interposed between the first and second interior surfaces, the flexible core component comprising a first end portion and a second end portion, wherein the first end portion comprises a coupling mechanism for coupling to the first interior surface to prevent translation of the first end portion with respect to the first endplate assembly, and wherein the second end portion is pivotable with respect to the second endplate assembly. - View Dependent Claims (59, 60, 61)
