Sacral therapy is a treatment method that uses large doses of medication dripped or injected into the lumen of the sacral canal. It is also called sacral shock therapy, which is called “liquid knife therapy” abroad. In recent years, the clinical treatment of high lumbar disc herniation has achieved satisfactory results. It uses the anatomical characteristics of the sacral canal, injects large doses of liquid, diffuses its pressure to the head, and has the functions of water impact, liquid stripping and suspension reset, forcing the herniated disc to reset. The drugs in the group formula also have the functions of anti-inflammatory, anti-swelling, pain relief, nerve nutrition and repair of tissue trauma. Because the pain-causing substances exuded by the necrotic nucleus pulposus of a herniated lumbar disc are the most common cause of stimulating the nerve roots to induce lumbar and leg pain, it is easier for the drugs to reach the lesion area by injecting them from the sacral canal nearest to the skin, and then using the drugs that can reduce the necrotic exudation of the nucleus pulposus, the effect of eliminating the inflammation and edema of the nerve roots can be achieved, thus quickly relieving the symptoms of sciatica, in addition, sacral therapy is also one of the methods to help diagnose the lesions in the spinal canal . From the epidural imaging shows that only impact injection can effectively make the drugs reach the lesion site of the lumbar spinal canal. Sacral canal impact therapy adopts several kinds of drugs and injects them into the cavity of the sacral canal in organic combination, so as to fight inflammation, reduce swelling, relieve pain, loosen adhesions, reset tissues, decompress nerves, improve cell metabolism and nourish nerve tissues, and promote nerve repair and regeneration, so as to achieve the purpose of treating diseases. The main indications of this therapy include: lumbar disc herniation, lumbar spine osteophytes, spinal stenosis, lumbar myofascial syndrome, lumbar myofascial strain, sciatica, pear-shaped muscle syndrome, lumbar, sacral and caudal pain and lower limb pain and discomfort, etc. It is especially effective for lumbar disc degenerative lesions, which may save more patients with lumbar disc herniation from surgery, and provide more patients with lumbar disc herniation who are unwilling to undergo surgery, or who cannot undergo surgery for various reasons. It opens up an ideal treatment method for patients with lumbar disc lesions who are unwilling to undergo surgery or cannot be treated surgically for various reasons. Mechanism of action: 1. Impact principle: i.e. inputting a certain dose of medicinal solution via the epidural to directly impact on the nerve root to slow down the nerve compression and get rid of the pain. 2, the principle of suspension and reset: that is, the drug input into the body in the spinal canal to form pressure. The nerve fibers that are adhered to the pressure are separated, so that the herniated intervertebral disc is infiltrated and suspended, thus returning to its original position and elasticity. 3, the principle of nutritional repair: the medicinal solution contains a variety of nutritional nerve cell components, which can promote blood circulation, thereby restoring the conduction function of nerves and nerve endings. Superiority: The therapy is safe and reliable, not hospitalized, Sui diagnosis and treatment, no obvious toxic side effects, 5-10 days treatment once, the drug solution absorption ability is extremely strong, is 10 times the subcutaneous absorption, therefore, it is more direct than oral, intramuscular, intravenous drug administration, more effective, is the current advanced treatment methods.
