METHOD FOR MAKING A METAL-BACKED ACETABULAR IMPLANT
First Claim
Patent Images
1. An acetabular implant comprising:
- a shell having an outer shell surface and an inner shell surface, the outer shell surface configured to contact bone;
an integument having an outer integument surface and an inner integument surface, the outer integument surface configured to couple to the inner shell surface; and
a plastic bearing having an outer bearing surface and an inner bearing surface, the inner bearing surface defining a socket, the inner integument surface configured to form a friction-fit with the outer bearing surface.

23. A method of forming a metal-backed acetabular implant, comprising the steps of:
-
providing a plastic bearing having an outer bearing surface and an inner bearing surface defining a socket; providing an integument having an outer integument surface and an inner integument surface; forming a sub-assembly by friction-fitting the outer bearing surface to the inner integument surface; providing a shell; and forming an implant by coupling the shell and the sub-assembly. - View Dependent Claims (24, 25, 26, 27, 28)
