Fluid flow around model femoral components of differing surface finishes: in vitro investigations.

Abstract:

We studied fluid flow at the stem-cement interface of bonded and debonded, polished and rough model femoral components. In a first series of experiments, fluid flow along the interface between bone cement and well-fixed model femoral components, differing in surface finish, and in shape, was measured. Fluid migration along the bone-cement interface of rough stems (Ra 3 microm) was greater than that on polished stems (p < 0.001). This was true of cylindrical and conical tapered stems. On st...
