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.
