Unique implants can replace damaged human bones

Experts from Russia's National University of research and Technology (NUST misis) have developed implants with UHMWPE as the main material for the first time in the world, which can be used to replace damaged human bones locally The experiment has been successful This research result has been published in the American Journal of materials science and engineering recently Local replacement of bone damaged by tumor disease, trauma or surgery is still an important medical challenge Russian experts have proposed to use UHMWPE as the main material for implants This time, researchers from nust misis have developed a multi-layer structure material implant similar to porous cancellous bone "The structure of this material is divided into two layers and closely connected with each other," said feodore shenatov, project director and researcher in the field of composite materials at the research center of nust misis In order to guarantee the mechanical firmness, the first layer of structure simulates the bone cortex The receptor cells will be located in some holes of the same size in the inner structure, so that the joint process between the implant and the surrounding tissues in the human body will be accelerated, and the implant will be more stable in the body " According to the experimental results, there was no rejection in all the experimental animals implanted with this material.
