In the 1950s, Russian orthopedic surgeon Dr. G.A. Ilyzarov (llizarov) discovered through long-term experiments and clinical trials that the human skeleton, just like connective and epithelial tissues in the human body, has a great deal of regeneration and plasticity, and that as long as a doctor grasps the laws of its development and growth, and utilizes a certain number of medical means, he can, to a certain degree, make the skeleton grow or shorten according to the doctor's wishes, thus making it possible to "recover" fingers, toes, etc. lost due to trauma. The doctor can make the bones grow or shorten according to the doctor's wishes by using certain medical means, so that the fingers and toes lost due to trauma can be "regained". The doctor also corrects and repairs certain congenital defects and acquired deformities in the human body. He spent more than ten years on the in-depth study of techniques and theories, and finally formed the tension-stress law of pulling tissue regeneration. The technique was widely used in the 1950s and cured a large number of patients with serious bone diseases caused by World War II. As a result, Prof. ilizarov was awarded the title of National Hero, received the Order of Lenin, the highest award of the Russian state, four times, and was regarded as a national hero by the Russians, receiving great honor and renown in the world of medicine. The Russian ilizarov Medical Center is affiliated with the Russian National Academy of Sciences, and its orthopedic surgical techniques and the doctrine of distraction osteogenesis have been hailed by the international orthopedic community as a new milestone in the history of orthopedic development. This famous technique was also named llizarov technique after Mr. llizarov. To date, the llizarov technique remains the most advanced orthopedic technique in the world.
