Polyethylene-based bone implant created in Russia

The implant, developed by a team of MISIS engineers, has a two-layer construction made of ultra-high molecular weight polyethylene. The outer layer is an imitation of the cortical bone, and everything inside is filled with pores of a certain size.

The function of the outer coating is to provide the strength of the implant. The porous internal structure is a kind of "incubator" where the recipient's cells can "settle" and "multiply". By filling the pores, they will securely fix the implant and accelerate the fusion of artificial tissues with living ones.

Ultra-high molecular weight polyethylene proved to be an ideal material for the formation of multilayer scaffolds that mimic the porous, spongy structure of bone tissue that meets the highest requirements.

Laboratory tests on animals have been successfully completed: prototypes of implants have successfully taken root.

Bone fractures are one of the most common types of injuries in Russia, as evidenced by the number of operations to restore their integrity - over 70, 000 per year. In some cases, bones are restored without the intervention of surgeons, but the body's capabilities are not unlimited, especially in complex fractures.
