Abstract: The invention relates to a method for coating of a medical implant that can be used to apply a calcium salt to the surface of a medical implant easily and without expensive coating equipment and little expenditure of time. Accordingly, a method is provided that includes (I) providing a medical implant that includes at least one surface to be coated; (ii) providing a body that includes at least one calcium salt with a Mohs hardness of no more than 5.5 on at least one of its surfaces; and (iii) rubbing said body having the calcium salt-containing surface onto the at least one medical implant surface to be coated in order to coat said surface of the medical implant with the at least one calcium salt.

Abstract: An initiator system for self-curing plastic material comprises a) at least one salt of a dialklylbarbituric acid and/or an alkylcycloalkylbarbituric acid and/or alkylarylbarbituric acid and/or a cycloalkylarylbarbituric acid that is insoluble in methacrylate monomers; b) at least one heavy metal salt that is insoluble in methacrylate monomers; c) at least one halogenide ion donor that is insoluble in methacrylate monomers; and d) at least one acid that is soluble in methacrylate monomers. The initiator system can be used for the preparation of paste/paste, paste/powder, paste/liquid, powder/liquid, and liquid/liquid combinations for the production of medical plastic material and dental materials. Additionally, a bone cement composition containing the initiator system is described.

Abstract: A surgical suture material with an antimicrobial surface is described, the surface exhibiting a coating containing a) at least one fatty acid, b) octenidine dichloride and/or dequalinium chloride and c) optionally oligomeric lactic acid esters. In addition, a process for coating surgical suture material is described which is characterized by the fact that the thread material is wetted with a homogeneous methanolic solution of octenidine dichloride and/or dequalinium chloride and subsequently the methanol is evaporated, a coating forming on the thread surface.

Abstract: What is described is a PMMA bone cement, containing at least one homopolymer or one copolymer having a glass transition temperature of more than 45° C., and at least one biocompatible elastomer that has a glass transition temperature of less than 37° C. and is soluble or insoluble in alkylmethacrylates and/or alkyldimethacrylates and/or alkyltrimethacrylates and/or alkyltetramethacrylates and has a residual monomer content of less than 5 percent. The PMMA bone cement is preferably used as self-curing plastic material for the fixation of primary total articular endoprostheses and revision total articular endoprostheses. Moreover, the PMMA bone cement can be used as self-curing filling material for vertebroplasty, kyphoplasty or femoral neck augmentation as well as for the production of temporary place-holders for two-stage revisions of total articular endoprostheses.
