Discogenic lower back pain refers to lower back pain that occurs when pain receptors within the disc receive painful stimulus signals. At present, it is thought to be caused by abnormalities in the internal structure and metabolic function of the intervertebral disc, such as disc degeneration (including disorders of the nucleus pulposus, rupture of the annulus fibrosus and cartilage endplate damage) or the release of certain factors (inflammatory mediators), which stimulate pain receptors within the annulus fibrosus. The concept of “intradiscal rupture” was introduced by Crock in 1986. The clinical manifestations are: pain in the interspinous, posterior iliac, posterior gluteal and both sacrospinous regions of the lumbar region, but also in the anterior inguinal region, anterior thigh and posterior lateral region. Generally the pain does not exceed the knee joint, but some patients occasionally have pain that exceeds the knee joint and cannot sit or stand for long periods of time. Physical examination: few objective signs, generally limited lumbar flexion and extension, rotation and other activities, but no obvious signs of nerve damage, straight leg raise test, femoral nerve pull test mostly negative. Diagnosis: 1, persistent or intermittent episodes of chronic lower back pain for more than 6 months. 2. Clinically, low back pain is predominant and may be accompanied by leg pain. No signs of sensory, motor and reflex impairment on physical examination. 3.X-ray and CT: There may be no typical positive findings or non-specific manifestations such as narrowing of the vertebral space and degenerative changes of the vertebral body. 4, MRI T2-weighted images of typical single-segment low-signal changes (black disc) or high-signal areas (HIZ) or Modic changes in the posterior part of the annulus fibrosus. 5. Positive discography pain provocation test Among them, discography pain provocation test is considered the gold standard for the diagnosis of discogenic low back pain. Treatment: 1. Non-surgical treatment: Most patients can relieve symptoms through general symptomatic treatment. Treatment methods include labor and rest, bed rest, traction, massage, physical therapy, non-steroidal anti-inflammatory painkillers and other treatments. 2.Minimally invasive treatment: percutaneous laser vaporization disc decompression (PLDD) technology, intravertebral disc endofibrothermal angioplasty (IDET), ozone myelolysis, discoscopic nucleus pulposus removal (MED), percutaneous discectomy, etc. 3.Surgical treatment: for recurrent symptoms, lasting more than 6 months; invalidated by regular conservative treatment for more than 4 months; positive discography can be treated surgically. The main surgical methods are lumbar fusion (PLIF, PLF, ALIF, TLIF), interspinous non-fusion fixation techniques (wallis, coflex), artificial nucleus pulposus replacement, artificial disc replacement, etc.
