Abstract: A 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.

Abstract translation: 一种用于插入包括多个由PMMA形成的间隔物的填充髓内髓质细管的假体植入物。 间隔件包括具有前部和后部的主体。 间隔物的主体随着从所述前部向所述后部的距离变窄。 当身体插入到水泥填充的髓内管中时，间隔物的狭窄体中断了植入体的水泥流动。 间隔物的较窄的后部使得水泥流平滑地重新附着到植入体上，而不会在水泥中产生实质的干扰或涡流。
