Abstract
The invention is directed to a method of attaching spikes (34) to an orthopaedic implant such as an acetabular cup (22). The acetabular cup (22) is formed with at least one tapered hole (28) therein which extends from an outside diameter (30) to an inside diameter (32) of the cup. At least one spike (34) having a tapered end (38) is pressed into a corresponding tapered hole (28) of the cup (22), whereby an interference fit is created between the tapered end (38) and the tapered hole (28). The spike (34) is metallurgically bonded to the cup (22), such as by electron beam welding and heat treating. The inside diameter (32) of cup (22) is then finished.
