A new material for joint prostheses has been developed in Russia, which has already passed certification and testing. Here are the details.
Scientists from St. Petersburg Polytechnic University (SPbPU) in collaboration with colleagues from the Technological Institute and the Almazov National Medical Research Center are studying thermoplastic polymers designed to create materials suitable for endoprosthetics.
According to the Ministry of Education and Science, the main goal of their work is to develop a safe and biocompatible material that is as close as possible in its characteristics to human bone. This will help solve the problems associated with modern implants, such as the destruction of tissues around titanium products.
Researchers focused on thermoset polymers that can be adapted to the individual needs of patients. The materials are tested in conditions simulating surgical operations: samples are created using 3D printing, then placed in blood plasma and exposed to extreme temperatures.
Senior Researcher Ilya Keresten noted that their method allows for a detailed analysis of the material's properties, including its structure, rheological behavior, and interaction with bone tissue. A key point is the creation of a porous structure that promotes the integration of the implant with the bone.
The next step will be experiments on animals to confirm the effectiveness of new developments. The university emphasized that the new technology can significantly reduce the time and cost of prosthesis production, allowing implants to be made directly on the operating table.
