Researchers from the Royal Institute of technology of Sweden have developed a substance that will allow you to create a biocompatible patch in place of damaged bone tissue. And thereby eliminate them without installing a metal pin or plates. The basis they took a polymer resin, which is already used for dental fillings.
The principle of operation of patch for bone identical to how they work with teeth. First, the damaged portion is applied acid ointment to the surface etching and exposure of collagen fibers. Then put a layer of polymer resin, which has micro – particles they adhere to the collagen fibers and create a stable relationship. It remains to illuminate the patch to run the thiol-alkenov reaction hardening substance.
Swedish scientists have developed a special version of the polymer resin, which in addition to strength provides the necessary flexibility of bone substance. It is 55% more effective than ordinary resin, according to the results of experiments on the bones of rats. Now the technology is prepared for clinical trials, and if they are successful, the Bonding company Biomedical AB will create a commercial version of the drug.
The methodology of the enormous prospects associated with what informed the idea of gluing the bones remained the prerogative of fiction. This was not the suitable materials. Now, in theory, could be used to treat arbitrarily complex fracture – it will be about the same as to glue the broken vase. Difficult, risky, but possible.
