Development of customized bone-repair granules with antibacterial properties

Follow-up — Al-Wasat Iraqi newspaper 

Scientists at the National University of Science and Technology in Russia have developed customized granules for bone repair that possess antibacterial properties.

The innovative granules are based on hydroxyapatite, a compound similar in composition to the mineral component of bone tissue; strontium and silver ions were added to their composition, giving them properties that aid integration with bone tissue as well as an antibacterial effect.

"This innovation was designed to fill large bone defects that can occur as a result of severe fractures, disease and surgical operations. The composition of the granules and their manufacturing technique allow control over their porosity, mechanical strength and the rate of their gradual dissolution in the body, a process that takes at least three weeks under laboratory conditions."

They noted that "this technique could in the future become a basis for producing orthopedic materials locally with controllable properties."
