<p>The distribution of short, fine, rough, surface titanium reinforcing fibers homogeneously throughout acrylic surgical bone cement is accomplished by adding the fibers in the form of bundles (20) of several hundred fibers (30) with the fibers being bonded to each other with an adhesive binder (50) that is soluble in the liquid monomer component of the bone cement. The fiber bundles (20) are either premixed with the powder polymer bead component of the bone cement followed by addition of the liquid monomer or the polymer and liquid are premixed into a viscous liquid and the fiber bundles are gradually added with stirring to the viscous liquid. In either case, as the adhesive binder (50) dissolves in the liquid monomer the individual fibers (30) are freed and the stirring mixes the fibers (30) homogeneously throughout the cement mass.</p> |
