A method for producing a polymethylmethacrylate bone cement, bone cement kit for use in such a method, and a bone cement producible by such a method

摘要

The invention relates to a polymethyl methacrylate bone cement. The method includes the steps of providing a cement powder containing at least one particulate polymethyl methacrylate or polymethylmethacrylate copolymer of the sieve fraction less than 100 microns, an initiator, and at least one methylmethacrylate insoluble, particulate or fibrous additive, the additive having an absorbency greater than or equal to 0, 6 g of methyl methacrylate per gram of additive at room temperature, further to provide a monomer solution containing at least one methyl methacrylate and an activator, and contacting the cement powder and the monomer solution, wherein the mixing is carried out without application of shear forces. The invention also relates to a bone cement kit for use in such a method and to a bone cement producible by such a method. for producing a polymethyl methacrylate bone cement with
