Ozone is often encountered in life. For example, exposed quilts and photocopier rooms have a slight ozone odor. As early as 1920, Italian professor Marco-Leonardi has started to use ozone ablation technology for clinical treatment, and later the technology gradually spread to Germany, France and the United States. In Germany and France, ozone water is mostly used to keep the oral cavity sterile for dental surgery, ozone is used in combination with radiation therapy for cancer treatment, and ozone is injected to treat varicose veins and intervertebral disc disease. In China, ozone therapy has been maturely applied to clinical treatment to achieve painless treatment of lumbar disc herniation and other bone and joint diseases. Intradiscal ozone injection is the most advanced minimally invasive treatment technology for disc herniation in recent years. It was first pioneered by Italian physicians and is now commonly used in some European countries such as Italy, Germany and France, and has been recognized as the most effective means of eliminating the need for surgery to treat lumbar herniation. The principle of intra-lumbar O3 injection is that high concentrations of O3 have a strong oxidizing power as well as anti-inflammatory and analgesic effects. When injected into the nucleus pulposus of the degenerated herniated disc, it can instantly oxidize the proteoglycans in the nucleus pulposus and destroy the nucleus pulposus cells, so that the function of proteoglycans is lost, the cellular production of proteoglycans is reduced, and the osmotic pressure of the nucleus pulposus cannot be maintained, resulting in water loss and atrophy, thus reducing the pressure in the disc and eliminating the symptoms, while ozone can also eliminate inflammatory mediators and kill bacteria. The joint action to achieve the purpose of treatment. What are the advantages of ozone ablation for lumbar disc herniation? The main advantages of ozone injection for the treatment of lumbar herniation: 1. High safety factor, fine needle puncture under local anesthesia, mainly on the nucleus pulposus, no effect on other tissues; 2. Minimally invasive treatment is less risky and more effective than conservative treatment, while eliminating the pain of incision; 3. Precise positioning. The positioning is accurate and deviation-free under CT or C-arm guidance; 4. The disadvantage of this procedure is that there is a certain recurrence rate. 5.No obvious postoperative complications. A few patients have transient limb weakness, and the symptoms disappear the next day. Ozone itself has a disinfecting effect, and the chance of infection is greatly reduced. 6.It can both atrophy the herniated medullary vertebrae and eliminate the aseptic inflammation of nerve roots. Precautions: Indications are discogenic low back pain, or with mild sciatica. It is less effective for those with bony spinal stenosis, disc prolapse or calcification. It is best to stay in bed for 3 days after surgery, and the patient is advised not to be sedentary or lift heavy objects in the future.
