In case of multiple complex bone fractures, special metal implants are used - screws and pins that fasten the damaged bone fragments together and ensure their fusion. However, this process is very slow and painful.
Against this background, a real revolutionary breakthrough was the development of a group of scientists from the University of Sydney headed by Halali Zreikat. They created a 3D ceramic implant that holds broken bones together and then turns into natural bone.
The implant has already been successfully tested in the restoration of limb fractures in rabbits. In addition, test results for similar fractures in sheep will be published shortly. In all eight animals, bone regeneration was successful.
Thus, sheep began to walk on their own the very next day after implantation, albeit in combination with a plaster cast to stabilize the process for four weeks. Three months after the operation, scientists recorded a complete recovery in 25% of the animals, and a year later this figure rose to 88%.
As the bones grow, the implant gradually becomes bone itself. As a result, it not only promotes healing, but also forms bone tissue in the places where it was lost as a result of trauma, and where the implant is no longer needed, it dissolves.
