Jewelry work of Japanese orthopedists
Ilya Ulyanov, "Kompyulenta"Japanese doctors are conducting clinical trials of a new bone restoration technology. Computer technology allowed them to achieve maximum accuracy in recreating damaged parts of the skeleton, and the special material of the implants promotes regeneration.
If the experiment is successful, doctors will be able to prepare perfect implants in a matter of hours in case of an emergency. Until now, orthopedists have used ceramic implants to repair damaged bone or resorted to transplanting natural tissue. Japanese scientists have used calcium phosphate (the main "building material" of the human skeleton) and a hardener consisting of 80% distilled water for the manufacture of artificial bones. The device developed by Tokyo-based firm Next 21, like a printer, recreates a bone with millimeter accuracy.
New implants created on the basis of computed tomography data are called CT Bone. Exact copying of complex bone shapes, according to experts, is of particular importance when recreating parts of the facial skeleton. According to Professor Tsuyoshi Tokato of the University of Tokyo, the implant can gradually be replaced with natural tissue, which was previously impossible.
Clinical trials will last approximately two years, seventy patients from ten medical institutions in Japan will take part in the experiment. The creators of the new technology plan to begin its practical application in three to four years.
