Claim:
1. A method for fixing a prosthetic implant to a patient's bone which comprises applying a bone cement formulation to a prosthesis attachment site, said bone cement containing: a. magnetic calcium phosphate nanoparticles present in an amount of 5.0-95 wt. % and having a largest linear dimension of 150 nm to 50 microns; b. polymerizable acrylate monomer present in an amount of 5.0-95 wt. %; c. polyacrylate polymer present in an amount of 0-80 wt. % and having a largest linear dimension from 5.0 to 500 microns; and exposing said bone cement formulation to an alternating magnetic field and generating heat sufficient to promote polymerization of said polymerizable acrylate monomer, wherein said alternating magnetic field is at a frequency of 100 KHz at a field strength of 5 KA/m to 40 KA/m.
