In Novosibirsk State Technical University scientists have discovered a new way to produce high-strength ceramics and developed a technology for the production of the first ceramic screws for the spine in Russia. In comparison with metal, they do not require replacement, and the patient will not need a re-operation.
In early April 2018, scientists of the Faculty of Mechanics and Technology were awarded silver medals at the Moscow International Salon of Inventions and Innovative Technologies "Archimedes-2018". Employees of the flagship university of Siberia managed to find a method for obtaining a dense ceramic material and to develop a technology for the production of screws for operations on the spinal column. Earlier in Russia, medical products made of high-strength ceramics were not produced.
The product is applicable in traumatology and orthopedics and can be used during surgical operations. The cost of the screws made of a new material is several times less than Western analogues. And yet one of the main features of the development is not the price, but the new material. Scientists of NSTU were able to increase the strength of the screw due to the addition of complex compounds (aluminum oxide with aluminomagnesium spinel). When screwed into the bone during surgeries, the new product remains intact, while the product from ordinary ceramics crumbles. The new material increases the resistance of the product to destruction.
Unlike the current metal screws, ceramics do not cause allergies and inflammations. Over time, metal medical products wear out, so their service life does not exceed more than 10 years. The development of oxide ceramics does not require replacement, so that the patient will be spared from repeated surgical interventions on the spine.
Medicine is not the only area of oxide ceramics to be used in. Scientists note that the material can also be used in metallurgy, radio engineering, power engineering, heating engineering and as a basis for creating other new materials.
