ABSTRACT:
The present invention is directed to polymethylmethacrylate bone cement that is premixed and frozen so as to arrest the polymerization reaction at a suitable point. The frozen bone cement is treated by electromagnetic radiation to insure sterility. In use, the bone cement is warmed until it reaches a temperature and consistency suitable for use. The bone cement may be prepackaged in a syringe, or may be molded for use in connection with a particular prosthesis, or may be packaged unitarily with a prosthesis.
