TOMSK, Sep 8 – RIA Tomsk. Scientists of the TSU Faculty of Physics and Engineering (FPE TSU) and Institute of Strength Physics and Materials Science (ISPMS SB RAS) studied the behavior of the "bone-endoprosthesis" system in the hip joint; this allow to personalize the process of creating prostheses, improve the quality and reduce costs, the university's press service said.

According to the press service, scientists of the FPE TSU and ISPMS SB RAS studied the "behavior" of prostheses made from the cobalt-chromium alloy used in Russia. So, they considered how the thickness of the coating of the prosthesis, the method of its application, roughness and other parameters affect the characteristics and wear of the product, explains the press service.

The study of scientists, in which they outlined how the "bone-endoprosthesis" system behaves in the hip joint at low physiological loads (walking, squatting, turning), is part of a project to develop a program for modeling individual prostheses.

"The data obtained is important for the creation of individual prostheses for a specific person and the development of personalized medicine in Russia. As a result, it will be possible to build a computer model, take specific patient parameters – weight, bone density, and others – and create an almost ideal prosthesis", – the professor of the FPE TSU Alexey Smolin participated in the study is quoted.

According to scientists, the creation of high-quality prostheses will help reduce the number of repeated operations to replace the product and reduce the cost of their production.

"The need for the design and manufacture of individual and high-quality prostheses is growing every year, for example, in Russia, from 2008 to 2013, the number of surgeries increased 2.5 times. At the same time, the share of the cost of an endoprosthesis is 55% of the total cost of surgery and rehabilitation, and the share of imported products on the Russian market is about 95%", – researcher of TSU and ISPMS Galina Eremina is quoted.
