1.Diagnosis of discogenic low back pain: The current diagnostic criteria for discogenic low back pain are: ① pain in the lumbar region, buttocks and thighs is not consistent with nerve root localization, lasts > 6 months, and is ineffective after > 4 months of regular non-surgical treatment; ② imaging data shows no obvious nerve root compression, no segmental instability and other definite lumbar spine diseases that cause low back pain; ③ magnetic resonance imaging shows significant disc (3) Evidence of disc degeneration on magnetic resonance imaging, such as black disc and high signal area at the posterior edge of the fibrous ring; (4) Discography showed degeneration of disc structure, pain replication effect, and one negative control disc. 2, clinical manifestations: the clinical manifestation of discogenic low back pain is low back pain, most have a history of trauma, often in the weeks or months after the injury, recurrent, gradually increasing pain in the lower back median deep in the pain, pain often does not reduce due to rest, can be accompanied by leg pain, this leg pain does not have a more clear area like radicular pain, rarely accompanied by skin numbness and other sensory abnormalities. Signs: patients can see lumbar muscle tension, lumbar pain is often caused when the lumbar spine moves; there is usually no pressure pain in the lumbar spine or paraspinal muscles; nerve root tension test is negative; sensation, movement and reflexes are generally not abnormal. Treatment of discogenic low back pain: The treatment of discogenic low back pain is divided into non-surgical treatment and surgical treatment. Non-surgical treatment is no different from other causes of low back pain, mainly bed rest, traction, massage, lumbar, physiotherapy, local topical drugs, etc. The following are several surgical treatments: 1. Minimally invasive surgery: minimally invasive technology is used to decompress or denervate the responsible intervertebral disc, mainly for patients whose disc degeneration is not too serious and whose integrity of the fibrous ring has not been completely destroyed. In recent years, minimally invasive techniques for the treatment of discogenic low back pain have developed considerably, such as thermal therapy, radiofrequency, laser, etc., which have been widely used at home and abroad. Radiofrequency ablation myeloplasty: Intradiscal radiofrequency ablation is a new technology developed in recent years. The principle is to destroy the structure of the nucleus pulposus through low-temperature radiofrequency ablation electrodes, so that the molecular chain of the nucleus pulposus breaks down and vaporizes, and the disc is “decapacitated”, while the disc is denervated and the transmission of nociceptive impulses to the disc is reduced. Radiofrequency ablation myeloplasty is a minimally invasive treatment technique between non-surgical therapy and open surgery, with an efficiency of 81-92%. 2.Open surgical treatment: intervertebral fusion internal fixation: It is the gold standard for the treatment of discogenic low back pain and the most commonly used method. Removal of the diseased disc and intervertebral fusion can completely remove the inflammatory factors in the disc, remove the pain caused by chemical mechanisms, and at the same time strengthen the stability of the degenerated disc of the lumbar spine and eliminate the pain caused by mechanical mechanisms. There are three main types of interbody fusion: posterior interbody fusion, anterior interbody fusion, and combined anterior and posterior fusion, with fusion rates ranging from 56% to 100%. Although the fusion fails in some cases, internal fusion is still one of the ideal methods for treating discogenic low back pain, and in cases where the fusion fails, most of the low back pain symptoms disappear or are reduced, probably due to the removal of inflammatory factors and elimination of chemical mechanisms. In addition, there are dynamic fixation, disc replacement, and molecular disc therapy, among others. All have not been widely performed because of their respective advantages and disadvantages.
