Lumbar disc herniation is caused by trauma or chronic strain injury, resulting in lumbar disc fibrous ring rupture caused by low back pain and herniation of the nerve compression of the lower extremities caused by radicular pain. Human lumbar intervertebral discs from the age of 17 years began to degenerate: on the one hand, the annulus fibrosus because of trauma or strain injury microfibers began to relax, fracture, the local become weak; on the other hand, the nucleus pulposus decreased in water content, elastin fibrosis. In young adults, some strong manual laborers, teachers, drivers due to occupational relationship more often. Early manifestation of lumbar pain, manifested as soreness or swelling pain, aggravated by exertion, the patient described as “my back is like broken”, can not force, activities are limited. Usually, when sleeping, the lumbar region is sore and sleepy, and the patient likes to put a cushion on it to make it feel comfortable. At this time, the fibrous ring of the lumbar intervertebral disc has been partially ruptured, and there is aseptic inflammation in the local area, and the lumbar area can not be cooled or exerted, or it will be aggravated immediately. And massage or heating localized physical therapy can significantly relieve pain. At this stage, patients often do the examination to take pictures and do CT, there is no evidence of lumbar disc herniation on imaging, and doctors often diagnose lumbar muscle strain, which is actually the early stage of lumbar disc herniation. This stage of treatment only requires outpatient treatment: two hospitalized formal conservative treatment. After the first or multiple episodes of lumbar pain, the micro-injury of the annulus fibrosus gradually expands, the nucleus pulposus fibrosis loses its elasticity, and the lumbar pain tends to worsen suddenly in the case of heavy lifting or minor sprains, and throbbing pains in the buttocks, the backs of the thighs, and the backs of the calves and the outer side of the calves. Coughing and sneezing can cause low back pain, limited bending, inability to wash your face and brush your teeth, turning over in bed can be painful, and putting on your own pants and shoes can be affected because these actions can cause increased pressure on the lumbar intervertebral discs and pull on the congested and swollen nerves. This indicates a significant rupture and herniation of the annulus fibrosus of the lumbar disc, which presses on the nerves and causes a large area of sterile inflammation in the surrounding area. Symptoms are typical and persistent, and the diagnosis is clear with imaging of a herniated lumbar disc on CT or MRI. At this stage, it is recommended to be hospitalized for formal conservative treatment: 1, lying in hard bed rest. 2, Chinese medicine ion introduction physiotherapy. 2, Chinese medicine ion introduction physiotherapy. 3, electromagnetic field physiotherapy. 4.Orally take 4 capsules of Chinese patent medicine Tongpao capsule 3 times a day. 5.Orally take western medicine celecoxib capsule 1 capsule once a day. 6.Static danshen to improve nerve microcirculation. 7.Sedation of mannitol dehydration to reduce intravertebral pressure. 8.Dexamethasone shock to block inflammation to eliminate edema. Treatment 10 days for a course of treatment, generally 1-2 courses of 90% of patients can get satisfactory results. However, there are still about 10% of patients who still can not relieve the pain, then enter the next step. Three intravertebral closure treatment. In a few patients who strongly prefer conservative treatment and refuse minimally invasive or surgical treatment, intralesional closure may solve some of the problems. The anesthesiologist is asked to give an epidural lumen placement, taking care that the tube should be buried about 10 cm under the skin to avoid premature dislodgement. Then the drugs are injected into the spinal canal through the epidural catheter: 5 ml of 0.75% bupivacaine + 15 ml of saline + 10 mg of dexamethasone + 0.5 mg of methylcobalamin injection totaling about 23 ml are injected slowly over 20-30 minutes. Generally the patient’s pain is relieved after the medication, and he can get out of bed and move freely, and his bowel movements are not affected. In a few patients, sensitivity to anesthetics may result in blocked anesthesia, which can be released in about 4 hours. Continuous use of 5-7 days, remove the catheter, half of the patients pain relief, at least temporarily avoid surgery. Four interventional therapy. For patients with severe pain, poor results of conservative treatment and unwilling to undergo surgery, interventional therapy may solve part of the problem. Including collagenase injection and ozone injection can dissolve part of the nucleus pulposus and relieve the symptoms, radiofrequency, laser and plasma knife can make the protruding lumbar disc crumple or reduce the pressure inside the disc through thermal effect and relieve the symptoms. Collagenase injections take 4-6 weeks or more to relieve symptoms and cause larger adhesions in the spinal canal, and their use is gradually decreasing. These treatments are less damaging and allow patients to get out of bed earlier, but they are not effective in removing the pressure-causing substances. Many cases relapse soon after a short period of relief, resulting in residual low back pain or mild leg pain, which is disappointing to the patients. Five intervertebral foraminoscopy minimally invasive surgical treatment. Fundamentally different from interventional therapy is the use of endoscopy under visualization to directly remove the nucleus pulposus of the intervertebral disc that protrudes into the spinal canal and oppresses the nerves, which has the advantages of safety, minimally invasive, visualization, and quick effect. Local anesthesia is safe as the patient interacts and cooperates with the doctor during the operation. The wound is only 7mm, no need for suture, and a Band-Aid can be applied, which is indeed minimally invasive compared to the 20mm of posterior discoscopy. The patient can see the herniated disc being removed and the nerves being released during the operation, which is a completely visualized operation, which is both safe and reliable. Immediately after the operation, the patient can feel the relief of back and leg pain, and the straight leg raising test is negative, and the patient can go down to the ground after 6 hours and be discharged from the hospital within 3 days. VI Simple nucleus pulposus removal. One of the most done procedures in the last 30 years, which has yielded both better results and explored many problems.
