Abstract
A modular orthopaedic implant system has first, second and third implant components. Two of the components have bores and the third component has a post. The third component can be assembled with either the first or second components with the post received in the respective bore of the other component. When assembled, the length of the post received within the bore of one of the components is greater than the length of the post received within the bore of the other component. The fatigue strength of the assembly with a greater length of the post received within the bore is greater, and this assembly can be used where such greater fatigue strength is needed and the other assembly can be used where a lesser fatigue strength is needed. Since the third component that is used in both assemblies may be the same, inventory may be reduced.
