Scientists of the Penza State University together with engineers of MedInzh Research and Production Enterprise developed a hip endoprosthesis model made of a carbon alloy.
Unlike its analogues, the material has improved strength characteristics and does not cause rejection in the body, said Mikhail Ksenofontov, senior lecturer of the Department of Traumatology, Orthopedics and Military-Extreme Medicine at the Medical Institute of Penza State University.
The project is part of the "Engineering of the Future" scientific and educational centre created under a national project.
"A hip endoprosthesis model has been developed, and now we are preparing for additional studies to obtain a certificate for its clinical use," the scientist said.
When developing the medical product, the creators used a carbon, borium and silicon alloy, which was not previously used for the production of large joints endoprostheses. "Artificial heart valves and c-spine intervertebral discs endoprostheses were made using this alloy, but the material is not so thick there. Not until now has it been possible to obtain the material in the amount that is sufficient to create monolithic structures of endoprostheses," Ksenofontov added.
Currently, endoprostheses made of metal and polymer materials, as well as more expensive ones made of ceramics, are widely used in medical practice. The carbon alloy developed in Penza makes it possible to increase the strength of the endoprosthesis and at the same time improve its engraftment.
According to the scientific and educational centre's programme, scientists will have obtained the permission for the endoprosthesis clinical use by the end of 2024. During 2021, it is planned to create a test-bed for the project and, subsequently, to conduct studies on the toxicological safety of the material on animals.
