Scientists at Samara State Medical University, affiliated with the Russian Ministry of Health, have developed innovative surgical screws designed to stabilise complex bone fractures. The new screws are fully absorbable within the body, eliminating the need for a second operation to remove them.
Professor Larisa Volevoi, Director of the University’s Research Institute of Biotechnology, explained that unlike conventional titanium screws — which typically require a follow-up surgery once the bone has healed — the newly developed screws gradually dissolve and are replaced by the patient’s own bone tissue.
She noted that the innovation removes the risks associated with secondary surgery, shortens recovery time, and reduces the burden on healthcare systems — an especially important advantage in the treatment of complicated injuries.
The screws are intended for use in osteosynthesis procedures, surgical operations that stabilise and reconnect fractured bone fragments. They are expected to be applied across trauma surgery, orthopaedics, and maxillofacial surgery.
Natalia Maksimenko, Deputy Director of the Research Institute of Biotechnology, stated that the screws meet strict safety standards. She explained that careful monitoring of the raw materials, combined with multi-stage processing to eliminate potential antigens, followed by final sterilisation using radiation, ensures their safe medical use.
According to the university’s press office, plans are underway to expand production of the new screws in 2026. Serial manufacturing is expected to begin that year, with widespread adoption in leading trauma centres anticipated by 2027.
