This kind of surgery is currently the most effective and most expensive minimally invasive height-increasing surgery. But it will take at least a year to recover. This surgery was originally performed as a corrective surgery for patients with rugged limbs. With the advancement of the times, this technology is used to increase the height of the human body. The principle of this kind of surgery to make people taller is: a person's height is determined by the length of the bones, and the length of the bones is determined by the continuous reproduction and growth of cartilage cells in the epiphyseal plate. When a person reaches the age of 17 to 20, the epiphyseal plate usually becomes thinner. It will no longer grow and develop. According to the biological principle of limb tissue regeneration under certain stress stimulation, osteotomy is used to reopen the closed bone growth line in the calf or thigh, and a limb extender with stretching effect is installed outside the body. According to each Personal tissue regeneration capabilities and characteristics, slowly lengthening the limb at a rate of 0.5 to 1 millimeter per day. Through active functional exercise, beneficial stress stimulation is produced on the osteotomy end, causing bone cells and other tissue cells of the limb to continue to divide and proliferate, thereby increasing the number and length of limb bones, skin, nerves, muscles and other tissues. This achieves the goal of minimally invasive heightening.
