Abstract
A medical implant includes a body and a porous structure attached to the body. A boss integral with the body extends outwardly from a surface of the body. The porous structure has a surface that cooperates with the boss of the body to prevent pullout of the body from the porous structure. In fabricating the medical implant, the body and the porous structure are formed separately and subsequently secured together.
Claims11
A method of fabricating an implant comprising the steps of:
- forming a body having a first surface with a boss extending outwardly therefrom, the boss being integral with the body;
- forming a porous structure;
- and
- securing the porous structure with the boss of the formed body,
- wherein the securing step comprises placing a first surface of the porous structure against a first surface of the body such that the boss extends through a hole of the porous structure wherein a first portion of the boss is within the hole and a second portion of the boss extends over a second surface of the porous structure remote from the first surface.
