Lumbar disc herniation is one of the main diseases causing low back pain and lower limb pain and numbness, the incidence of which has been increasing in recent years, seriously affecting people’s quality of life. Its pathogenesis is based on chronic strain and disc degeneration, mostly occurring in L4-5, L5-S1 and L3-4, manifesting as lumbar and hip pain with lower limb radiating pain. Minimally invasive interventional methods are used, i.e. puncture of the intervertebral disc or herniation under C-arm guidance and combined treatment of lumbar disc herniation with ozone nucleus pulposus chemical lysis + radiofrequency thermocoagulation or PlDD. 1.Translumbar safety triangle puncture of the intervertebral disc or puncture of the herniated material via the medial margin of the small joint in the posterior approach, and injection of ozone and/or radiofrequency thermocoagulation for the treatment of disc herniation. 2.Translumbar safety triangle puncture of the intervertebral disc or posterior small joint medial margin puncture of the herniated object, injection of ozone and/or PLDD for the treatment of herniated disc. Treatment mechanism: 1.Ozone: with strong oxidizing effect, it can eliminate pain by dissolving proteoglycans in the nucleus pulposus, reducing disc pressure and eliminating immune inflammatory response in the nerve root or spinal canal. 2.Radiofrequency thermal coagulation: coagulation of nucleus pulposus material reduces disc pressure and shrinks the protrusion; by heating and destroying the sinus vertebral nerve in the annulus fibrosus, thus eliminating pain. 3, PLDD is a new generation of percutaneous laser disc decompression, which uses a light guide fiber smaller than a needle to introduce laser light into the intervertebral disc to vaporize the nucleus pulposus and disappear, thus removing the compression of the nerve and achieving the purpose of treatment. Advantages: 1. Minimally invasive: fine needle puncture, no incision, no destruction of normal bony structures; 2. High safety: puncture under image guidance, and precise positioning by imaging and electrophysiological testing; ozone and radiofrequency have almost no adverse effects on normal tissues of the body after precise positioning. 3, good results: postoperative excellent rate of more than 80-90%; 4, very few complications: rare complications such as bleeding, infection and nerve damage; 5, small medical expenses: short hospitalization time, rapid postoperative recovery, low cost. Precautions: 1, informed consent before surgery, the patient is willing to accept this treatment method. 2.Perfect all examinations before surgery, and control diabetes, hypertension and coronary heart disease in an appropriate state. 3.Local residual pain may exist after surgery, which needs to be treated symptomatically. 4.Wear a waist brace for three months after surgery and avoid strenuous activities of the waist. 5.Avoid lifting and carrying heavy objects after surgery. 6.According to the specific situation, it is feasible to exercise the lumbar back muscle. 7.Regular follow-up and follow up on discomfort.
