AbstractA prosthetic implant for insertion into a cement filled intramedullary canal including a plurality of spacers formed from PMMA. The spacers include a body having a frontal portion and a trailing portion. The body of the spacers narrowing with distance from said frontal portion toward said trailing portion. The narrowing body of the spacers interrupting the flow of cement along the implant body as the body is inserted into a cement filled intramedullary canal. The narrowing trailing portion of the spacers cause the cement flow to smoothly re-attach to the implant body without creating substantial disturbances or vortexes in the cement.
