A few days ago, a parent came to the outpatient clinic to ask whether it is possible to break the bone to increase the height of the child because the child is short. We would like to remind parents that if your child is short, do not break the bone to increase the height. Broken bone heightening surgery, also known as bone lengthening surgery, is mainly for patients with limb deformities done by the corrective surgery, mainly applicable to the sequelae of polio, natural or due to accidents such as car accidents caused by the length of the two legs of patients. Broken bones to increase the height of the leg is to use external forces, the leg “broken”, and then external forces to stretch, in order to achieve the purpose of “taller”, which need to adapt to this external force not only the bone, but also the nerves, blood vessels, muscular tissues and so on. Dangerous. The risk of breaking bones to increase height is very great: Risk 1: may damage the blood vessels, muscles and nerve tissues of the leg; may cause perforation and infection, and even cause osteomyelitis, resulting in disability. Risk two: the limb lengthening speed if too fast, will make the leg nerve, blood vessel damage, leading to leg nerve paralysis and blood vessel blood supply obstacle, this will cause lower limb necrosis, leading to amputation or paralysis. Risk 3: 3% to 5% of the general population are patients with osteogenesis imperfecta and aplastic anemia, once the medical examination before surgery is omitted, the consequences will be unimaginable. Risk 4: Due to the increased pressure on the knee joint caused by surgical augmentation, the lack of scientific knee exercises will result in stiffness of the knee joint and even disability. The Ministry of Health issued a strict management of “limb lengthening” notice, requiring limb lengthening must be carried out in qualified medical institutions, the notice also stipulates that limb lengthening must be carried out to strictly grasp the clinical indications for the application of limb lengthening, and the development of specific measures to safeguard medical safety. The technical indications for congenital malformations, trauma, tumors, infections and other causes of bone defects or limb unequal length, as well as limb deformities caused by disease. The use of limb lengthening is strictly prohibited if the above indications are not present.
