Background: The interfacial mechanics at the bone-cement or implant-cement interfaces is a critical issue for implant fixation and the filling of tissue defects created by disease. Electro spanning is a process by which fibers with sub-micron diameters can be obtained from an electrostatically driven jet of polymer solution. These fibers have a high surface area to volume ratio, which have numerous engineering applications. The present study is based on the hypothesis that the differences of the surface properties at bone/ cement interface due to incorporation of micro and sub-micron diameters fiber may have significant influence on the quality of bone/cement union.
