Abstract
A synovial prosthetic member includes a body having an articulating surface and an anchor surface, the articulating surface being configured for articulation with another articulating surface of a synovial joint, the anchor surface being configured for cementing to bone, the body being composed of ultrahigh molecular weight polyethylene (UHMWPE), the anchor surface having been subjected to treatment by either ion implantation, ion beam assisted deposition, or sputter deposition.
Claims19
A synovial prosthetic member which includes a bone-engaging surface having enhanced adhesion characteristics for cement comprising:
- a body having an articulating surface and bone-engaging surface;
- said articulating surface being configured for articulation with another articulating surface of a synovial joint;
- said anchor surface being configured for cementing to bone;
- and
- said anchor surface being characterized by subjection to treatment by a member of the class consisting of ion implantation, ion beam assisted deposition, and sputter deposition, such that said treated, bone-engaging surface of said prosthetic implant has enhanced adhesion characteristics for cement.
