Low back pain and lower limb pain are typical manifestations of lumbar disc herniation, and suffering from this disease even more seriously affects the quality of work and life. Due to the risk of surgical treatment, most patients will take conservative treatment. This is the case of Mr. Li, who is more than 50 years old and has been suffering from lumbar disc herniation for many years, has been conservative treatment, but the effect is very bad, and the condition is getting worse. Walking with the help of tools, not to mention the farthest can only walk a 20-meter look. Most of the time, he was bedridden and needed to be taken care of by his family. In early November 2014, because the pain was unbearable, Mr. Li came to the orthopedic surgery department of the Third Affiliated Hospital of Xinxiang Medical College. Based on Mr. Li’s symptoms, he was advised to undergo minimally invasive intervertebral foraminoscopic surgery. At first, Mr. Li was worried, but after hearing that it was minimally invasive and would not affect the stability of the lumbar spine, he gladly accepted. “The intervertebral foraminoscopy system is mainly for herniated prolapsed and free lumbar disc herniation, and also addresses lumbar spinal stenosis and nerve root canal stenosis.” The principle of intervertebral foraminoscopy is to use the physiological or enlarged physiological spinal foramen to remove the diseased nucleus pulposus tissue through the intervertebral space or intervertebral foramen to achieve full decompression of the nerve roots and unaffected spinal stability. After the preoperative preparation, Mr. Li’s surgery was performed under local anesthesia, with only a 7.5 mm orifice in the skin, followed by a transvertebral foraminal approach under the influence of a CB machine to remove the herniated or prolapsed nucleus pulposus or other tissue compressing the nerve under direct endoscopic vision. The surgery went well, and a few hours after the operation, Mr. Li was able to get out of bed and walk slowly, step by step, along the handrails of the ward corridor, and had walked several times. The lumbar spine stability was not affected because the foraminoscope does not destroy the osteoarticular ligament structure. The procedure also does not require pulling the nerve and dural sac, and there is no obvious interference with the nerve tissue in the spinal canal, which does not lead to obvious bleeding and adhesions in the spinal canal. The surgery is less traumatic and the postoperative bed rest time is short. Recently, the hospital has performed eight such procedures in a row, and the patients were able to get out of bed soon after surgery. This type of intervertebral foraminoscopy for lumbar disc herniation was pioneered by the Third Affiliated Hospital in the city and achieved very good treatment results.
