There are many methods of conservative treatment for lumbar disc herniation, and ozone treatment for lumbar disc herniation is a better treatment method. The principle of ozone treatment for herniated lumbar disc is that, firstly, it can destroy the proteoglycans in the nucleus pulposus of the lumbar disc, so as to make the nucleus pulposus dehydrated and atrophied and release the pressure of the nucleus pulposus of the lumbar disc on the nerves, and then the clinical symptoms will be relieved or even disappear. Secondly, ozone can also reduce the secretion of proteoglycans in the nucleus pulposus of the lumbar disc, thus making the herniated nucleus pulposus retracted, and then the herniated lumbar disc can be treated. Ozone treatment for herniated lumbar discs generally has better results in clinical practice, and is a minimally invasive, conservative treatment that works well for younger patients with milder symptoms, leaving a better chance for reoperation. Therefore, the effect of ozone treatment for herniated lumbar discs is remarkable, and many patients can be cured.
