Abstract
A bone cement composition includes, as the principal component, powdered copolymers of methyl methacrylate and methyl acrylate, or monomeric methyl methacrylate, and, in addition, gentamicin hydrochloride and/or gentamicin hydrobromide, or a mixture of gentamicin sulfate with sodium chloride, potassium chloride, sodium bromide and/or potassium bromide. The bone cement composition is used, for example, for cementing implants in place, for the anchoring of endoprostheses of the joints, in the treatment of skull defects, and for carrying out spinal fusions. The composition provides for antibiotic release in higher concentrations to prevent infections.
