Method of sterilizing an orthopaedic implant
A pre-assembled orthopaedic implant adapted for improved gas sterilization. The implant includes a first component adapted for assembly with a second component such that a mating surface of the first component is in close proximity with a mating surface of the second component. At least one gas conduit associated with the mating surface of the first component facilitates a sterilizing gas to penetrate into and dissipate from the interface defined by the mating surfaces.
1. A method of sterilizing an orthopaedic implant comprising the steps of: a. providing a first orthopaedic component, the first orthopaedic component having a first orthopaedic component mating surface; b. providing a second orthopaedic component, the second orthopaedic component having a second orthopaedic component mating surface; c. associating at least one gas conduit with at least one of the first orthopaedic component mating surface and the second orthopaedic component mating surface; d. assembling the second orthopaedic component to the first orthopaedic component such that the first component mating surface confronts the second component mating surface to define a mating surface interface; e. subjecting the assembly to a gas sterilization process such that the at least one gas conduit facilitates a sterilization gas to substantially penetrate the mating surface interface; f. providing a stem; g. assembling a femoral head to the stem; and h. assembling the femoral head to the first orthopaedic component or the second orthopaedic component.
2. The method of sterilizing an orthopaedic implant of claim 1 , wherein the step of subjecting the assembly to a gas sterilization process comprises subjecting the assembly to an ethylene oxide gas sterilization process.
3. The method of sterilizing an orthopaedic implant of claim 1 , wherein the step of subjecting the assembly to a gas sterilization process comprises subjecting the assembly to a vaporized hydrogen peroxide gas sterilization process.
4. The method of sterilizing an orthopaedic implant of claim 1 , wherein the at least one gas conduit is associated with the first orthopaedic component mating surface.
5. The method of sterilizing an orthopaedic implant of claim 1 , wherein the at least one gas conduit is associated with the second orthopaedic component mating surface.
6. The method of sterilizing an orthopaedic implant of claim 1 , wherein the at least one gas conduit is associated with both the first orthopaedic component mating surface and the second orthopaedic component mating surface.
7. The method of sterilizing an orthopaedic implant of claim 1 , wherein the step of assembling the second orthopaedic component to the first orthopaedic component comprises press fitting the second orthopaedic component into the first orthopaedic component.
8. The method of sterilizing an orthopaedic implant of claim 1 , further comprising the step of assembling a retaining ring to the first orthopaedic component or the second orthopaedic component.
9. A method of sterilizing an orthopaedic implant comprising the steps of: a. providing a liner, the liner having a liner mating surface and at least one gas conduit; b. providing a shell, the shell having a shell mating surface; c. assembling the liner to the shell such that the liner mating surface confronts the shell mating surface to define a mating surface interface; d. subjecting the assembled shell and liner to a gas sterilization process such that the at least one gas conduit facilitates a sterilization gas to substantially penetrate the mating surface interface; and e. assembling a femoral head to the liner.
10. The method of sterilizing an orthopaedic implant of claim 9 , wherein the step of subjecting the assembly to a gas sterilization process comprises subjecting the assembly to an ethylene oxide gas sterilization process.
11. The method of sterilizing an orthopaedic implant of claim 9 , wherein the step of subjecting the assembly to a gas sterilization process comprises subjecting the assembly to a vaporized hydrogen peroxide gas sterilization process.

13. The method of sterilizing an orthopaedic implant of claim 9 , further comprising the steps of: a. providing a stem; and b. assembling the femoral head to the stem; and c. assembling the femoral head to the liner.
14. The method of sterilizing an orthopaedic implant of claim 9 , further comprising the step of securing the femoral head.
15. A method of sterilizing an orthopaedic implant comprising the steps of: a. providing a liner, the liner having a liner mating surface and at least one gas conduit; b. providing a shell, the shell having a shell mating surface; c. assembling the liner to the shell such that the liner mating surface confronts the shell mating surface to define a mating surface interface; d. subjecting the assembled shell and liner to a as sterilization process such that the at least one gas conduit facilitates a sterilization gas to substantially penetrate the mating surface interface, and e. assembling a retaining ring to the shell.
16. The method of sterilizing an orthopaedic implant of claim 15 , wherein the step of subjecting the assembly to a gas sterilization process comprises subjecting the assembly to an ethylene oxide gas sterilization process.
