Scientists of NSTU have created heavy-duty ceramic screws for the spine

Scientists of the Novosibirsk State Technical University (NSTU) have opened a new way of obtaining high-strength oxide ceramics and developed a technology for the production of the first ceramic screws for the spine in Russia, RIA Novosti reported citing the press service of the university.

"Employees of the basic 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. Unlike metal, they do not require replacement, and the patient will not need a repeat operation", – the report says.

The university explained that specialists 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 operations, the new product is preserved intact, whereas the product made from conventional ceramics may crumble.

"In contrast to the currently used metal screws, ceramics do not cause allergies and inflammations. Over time, metal medical products wear out, so their service life does not exceed 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", – noted in the NSTU.

The press service said that the cost of products from the new material is several times less than Western counterparts. Developments for the production of ceramics and the production of new generation screws are patented. A trial batch of new screws has already been manufactured at JSC "NEVZ-Ceramix".

The university added that the field of application of oxide ceramics is not limited to medicine. The material can also be used in metallurgy, radio engineering, power engineering, heating engineering and as a basis for creating other new materials.
