Abstract: The doughy bone cement mixture is formed by mixing a powder-form polymer, such as polymethylmethacrylate, with a polymerizing liquid monomer, such as a liquid monomeric methylmethacrylate, to form a water-insoluble composition and admixing this composition with a biologically-compatible high-viscosity aqueous gel to form a dispersion of the composition with the gel. The gel is soluble in water as well as in body fluids so as to dissolve out after implanting of an implant or joint end in a bone. This allows the remaining component of the cement to become porous and, thus, allows for tissue invasion over a course of time to further anchor the implant or joint end. The gel may consist of partially neutralized, carboxymethyl cellulose dissolved in water.
