First, drugs 1, the role of drugs; anti-inflammatory, pain relief, blood circulation, nutrient nerve, nerve repair. 2, the side effects of drugs; medicine is three times poisonous, any drug with a good medicine, used is poisonous. 3, the toxicity of drugs; (1) long-term, small dose use. (2) short-term, large-dose use. Tong’s non-invasive intervention has been carried out for more than 20 years, during which we have made many adjustments to the varieties of drugs in a timely manner according to the patient’s therapeutic effect and clinical response, and at present, the drugs we have chosen to use have fewer side-effects and better therapeutic effect, except for Salvia divinorum, which are all imported from Japan. For the principle of side effects of drugs, and according to the mechanism of lumbar synostosis treatment, that is, not short-term, large doses of drugs; not long-term, small doses of drugs. We inject a small dose of drugs, and let the last period of drug absorption, excretion, and then do the next time, so that the drug does not accumulate in the body, that is, to reduce the side effects of the drug, but also give full play to the role of drugs. Second, the risks and complications of children’s non-invasive interventional therapy due to the high-precision end of the CT scan, guided by the lumbar intervertebral discs, sciatic nerves, blood vessels, soft tissues, intervertebral foramina, small joints of the vertebral body and other tissues displayed clearly, coupled with more than 20 years of experience in interventional therapy operations, making children’s non-invasive interventional therapy risk reduced to zero.
