One of the most promising methods for biomedical coating formation is based on the use of vacuum arc plasma sources that allow pure metals to be obtained and plasma-chemical synthesis of complex compounds to be carried out. In this work, the results of synthesis of titanium nitride and titanium carbide on metal substrates using specially developed equipment are presented.

Creation of nanosize coatings from two-dimensionally ordered linear chain carbon (TDOLCC) on the surfaces of biological heart valve prostheses had no significant influence on the adhesion of clinical strains of microorganisms. However, studies of the viability of test cultures on modified biotissue surfaces showed that adherent staphylococcal cultures did not retain viability, with the exception of Staphylococcus saprophyticus. Viability results for Gram-negative cultures varied: from the absence of growth in the case of Klebsiella pneumoniae on biotissues with TDOLCC to continuous growth of strains of Pseudomonas aeruginosa and Acetinobacter baumannii on the same surfaces. Doping of TDOLCC coatings with nitrogen prevented test culture adhesion and colonization (except for Candida albicans) after artificial inoculation of modified bioprostheses with clinical strains of microorganism

The interest in the relatively new and promising direction of employing osteointegration continues to increase worldwide. This article describes an original intraosseous femoral fixation system and demonstrates approaches to and the design characteristics of such systems.
