RosUniMeda scientists have invented bioresorbable fixation systems for maxillofacial surgery

In April 2024, the Russian University of Medicine of the Ministry of Health of Russia received a patent for invention No. 2817502 "Fixator for osteosynthesis". The uniqueness of the patent lies in the fact that for the first time in the world, a screw design has been developed that is specifically designed for new generation surgical operations: screws for maxillofacial surgery will be made of a biodegradable magnesium-based alloy. This means that soon surgeons will not need to perform a repeat operation to remove the metal structure after the completion of the process of osteosynthesis (formation of bone tissue), the fixing screw will gradually "dissolve" inside the bone, and the rate of "resorption" will practically correspond to the rate of growth of the bone tissue itself.
The innovative development was carried out by the staff of the laboratory of medical bioresorption and bioresistance under the guidance of Professor Rosunimed Drobyshev A.Yu. in fruitful cooperation with colleagues from the laboratory "Hybrid Nanostructured Materials" of NUST MISIS. The project is being implemented within the framework of the megagrant of the Ministry of Science and Higher Education, which has been received and successfully implemented by our university since 2022. A leading world-class scientist, Professor of Seoul University, Mr. Shin Kwang Song, is participating in the project. The Russian University of Medicine of the Ministry of Health of Russia has submitted to Rospatent the necessary documents to obtain a patent for another type of bioresorbable products – plates. Together with screws and a special tool that is currently being developed by our scientists, they will make up a fixation system for maxillofacial surgery. And the research team plans to develop a wide range of bioresorbable magnesium products for orthopedics, neurosurgery, veterinary medicine, etc.
