Abstract
An implant stem 10 and distal centralizer 20. Implant stem 10 has a plurality of longitudinal channels 14 formed around its periphery adjacent its distal end 12. Channels 14 converge radially toward the apex of the stem distal end 12. Channels extend only partially into the body of implant stem 10 to provide sufficient material to maintain the structural integrity of the distal end of the implant. Centralizer 20 includes a plurality of radially extending blades 22. The proximal end of each blade 22 is shaped to extend upwardly for securely mating with implant stem 10. The complimentary cruciate configuration of channels 14 and blades 22 allows centralizer 20 to be securely attached to implant stem 10.
