Abstract: The present invention relates to a cement which may be used for the fixation of osseous prostheses. This cement is obtained by hardening of a mixture comprising:(a) at least one epoxide resin having a high reactivity and a very low toxicity, consisting of a diepoxide of a glycidyl ether of bisphenol A;(b) a reactive, non-toxic suppling resin, consisting preferably of hydroxyl-terminated polybutadiene;(c) a mineral filler in powder form;(d) a hardener capable of reacting with said epoxide resin to effect hardening thereof, and(e) a hardening accelerator.The invention is more particularly applicable to the fixation of hip prostheses.
