The paper presents the possibility of using an innovative hydroxyapatite filament Ca10(PO4)6(OH)2 for printing in 3D printers of bone implants and the possibility of using it during implantation with voice prostheses. The introduction of an additional colloidal silver composite in voice implants will contribute to the reduction of bacterial infections, fungal infections and granulomatous hyperplasia. The creation of a stable external ring of the vocal fistula will remove complications associated with it with enlargement of the fistula and leakiness of voice implants. The ability to print with a hydroxyapatite filament will allow digital pre-surgery modeling of bone implants suited to the needs of surgical procedures.

Biofilm formation represents a significant cause of concern as it has been associated with increased morbidity and mortality, thereby imposing a huge burden on public healthcare system throughout the world. As biofilms are usually resistant to various conventional antimicrobial interventions, they may result in severe and persistent infections, which necessitates the development of novel therapeutic strategies to combat biofilm-based infections. Physicochemical modification of the biomaterials utilized in medical devices to mitigate initial microbial attachment has been proposed as a promising strategy in combating polymicrobial infections, as the adhesion of microorganisms is typically the first step for the formation of biofilms. For instance, superhydrophobic surfaces have been shown to possess substantial anti-biofilm properties attributed to the presence of nanostructures. In this article, we provide an insight into the mechanisms underlying biofilm formation and their composition, as well as the applications of nanomaterials as superhydrophobic nanocoatings for the development of novel anti-biofilm therapies.

Purpose of study: to analyze the modern approaches to classification of large joints periprosthetic infection (PPI) and evaluate the results of revision surgical interventions in patients with deep PPI of the knee. Patients and methods. One hundred fifty three patients, 51 men and 102 women (mean age 57.3±12.4 years), with deep PPI were operated on. Treatment tactics was determined by the term after primary operation. In early PPI (n=31) sanitation interventions with implant preservation and in late PPI (n=122) – two step interventions with long period between the operations (over 4 weeks) were performed. Results. Follow up made up from 2 to 5 years. Sanitation interventions with implant preservation were successful in71% of patients. In group of patients with late PPI satisfactory results were achieved in 89.6% of cases. On the basis of the obtained data the variants of diagnosis and treatment tactics optimization as well as its adaptation to domestic public health system were proposed.
