Abstract
A method of adhering bone to the surface of a rigid substrate such as a metal or resin prosthesis using an improved surgical bone cement. The bone cement has mechanical properties more nearly matched to those of animal bone and thermal curing characteristics which result in less traumatization of body tissues and comprises a dispersion of short high modulus graphite fibers within a bonder composition including polymer dissolved in reactive monomer such as polymethylmethacrylate dissolved in methylmethacrylate monomer.
Claims7
A method of adhering bone to the surface of a rigid substrate comprising the steps of:
- applying to the bone and surface a surgical bone cement composition comprising a dispersion of 2 to 12% by weight of high modulus graphite fibers having a diameter from 1 to 50 microns and a length from 0.1 mm to 15 mm within a biocompatible polymer dissolved in a biocompatible reactive monomer;
- and
- curing the cement to form an adherent flexural bond.
