摘要
A bone cement comprising an acrylic polymeric component and an inorganic component comprising a bioactive glass or glass-ceramic, comprising at least one metal oxide having an anti-bacterial activity, wherein said glass or glass-ceramic component is adapted to release ions of said metal in contact with physiological fluids. The bone cement performs a sustained antibacterial action, also promoting binding with the tissues with which it is contacted, and it is advantageously employed in the fixation of orthopaedic prostheses, in the production of temporary prostheses and in spinal surgery.
