  • Bone cement having improved mechanical properties, and process for the preparation thereof
    Patent number: 7160932
    Abstract: Bone cements containing polyacrylates or polymethacrylates and an X-ray contrast medium can be prepared by functionalizing the X-ray contrast medium with (meth)acrylate groups prior to being coating with melamine-formaldehyde resin and subsequent polymerization. The invention resultant bone cement can be used for anchoring prosthesis components in bone, for stiffening bone, as bone screw fixing plug and as implants for anchoring screws.
    Type: Grant

    Date of Patent: January 9, 2007
    Assignee: Biomet Deutschland GmbH
    Inventors: Frank Schilke, Berthold Nies, Brigitte Jeschke, Matthias Koch, Armin Kuebelbeck
  • Use of antiseptic active principles in pmma bone cements
    Publication number: 20060275339
    Abstract: The invention concerns the use of polyhexamethylene biguanide in PMMA bone cements, which preferably do not contain antibiotics. The cements exhibit a concentration of active principle not exceeding 1 wt. % relative to the total weight of the cement, which is a concentration sufficiently high to prevent microbial colonization of the cement surface. The cements do not cause durable alteration of the healing process.

  • Functionalisation of unreactive substrates
    Publication number: 20040185252
    Abstract: The invention describes a process for the production of functionalised unreactive substrates in which the surface of the substrate is firstly coated with a melamine-formaldehyde resin and subsequently reacted with a functionalising reagent.
