Abstract
Disclosed are apparatus, systems and methods for crosslinked, oxidatively stable, spinal implants. More specifically, the invention provides spinal implants, systems and methods of forming spinal implants from a polymer blend stabilized with Vitamin E to improve performance, wear and/or fatigue resistance.
Claims20
A spinal implant assembly comprising:
- a superior component, the superior component comprises an upper base and an upper articulation component, the superior articulation component comprises a polymer material and a stabilizing component, the superior articulation component further comprises a concave surface;
- and
- an inferior component, the inferior component comprises a base, an inferior articulation component, and a bridge, the inferior articulation component comprises a convex surface, the bridge extends from the base towards the posterior direction,
- wherein the concave surface of the superior articulation component of the superior component contacts the convex surface of the inferior articulation component of the inferior component to create an articulation joint.

A method of forming a stabilized spinal implant comprising:
- creating an antioxidant stabilized polymer (ASP);
- completing a first processing of the ASP to create a preformed implant;
- completing a first cross-linking of the preformed implant using a selected first technique with a first dose and a first controlled environment;
- completing a second processing of the preformed implant to create a final implant;
- packaging the final implant in a packaging container within a packaging controlled environment;
- and
- completing a second cross-linking and sterilization of the final implant with a selected second technique with a second dose and a second controlled environment.
