First-ever a knee joint operation with use of technologies Additive technologies bone fabric was carried out by
As were declared by doctors, operation took place successfully. The man in the first day after operation could execute independently the main movements by a "new" knee, and, as expected, in four-five days will be already written out.
the First hospital of Medical university of the province Province of Anhui performs more than 400 operations on replacement of knee joints annually. However, as physicians note, is frequent because of postoperative infections and other complications in bone fabric surrounding joints there were various defects. For this reason production of the individual, tantalic implants designed by means of computer design playing a role of a peculiar buffer between an artificial joint and living tissues, allowed to solve this problem. Tantalum is traditionally used in stomatology and production of surgical implants and practically is not torn away by a living tissue of an organism.
the Technology Additive technologies appeared in 1983 thanks to opening of the American inventor Charles Khall. In 1999 it was for the first time applied in medical practice by group of scientists and doctors of Institute of regenerative medicine of university Ueyk Forrest (United States of America) which implanted to the patient the body which has been grown up in laboratory on the basis of cells of the patient. Operation became precedent of creation of the exact copy of body of the patient - a bladder - by means of a computer tomography and 3D - the printer.
In March, 2015 the Chinese company Xi’an Particle Cloud Materials Technology Co. Ltd. announced successful tests for animals of the organic bone implants made on 3D - the printer. Samples of the printed fabric showed high level of growth of new cages and were for the first time approved on rabbits, transfers information agency "ITAR-TASS" .
