The hydrostatic extrusion of polyethylene filled with hydroxyapatite has been studied. It is shown that the extrusion behavior is qualitatively similar to that of unfilled polymer. Extruded products with flexural moduli of at least 10 GPa and flexural strengths of 90 MPa have been produced, which can be considered as candidates for load-bearing bone substitute materials. © 1997 John Wiley & Sons, Ltd.
