Discogenic lower back pain is an extremely common and clinically prevalent condition, which is chronic lower back pain caused by intravertebral disc disorders (IDD) such as degeneration, internal fissure of the annulus fibrosus, and discitis that stimulate pain receptors within the disc without radicular symptoms, without radiographic evidence of nerve root compression or excessive displacement of vertebral segments, and can be described as chemically mediated discogenic pain. The current diagnostic criteria for discogenic low back pain are as follows: 1. Recurrent episodes of lower back pain, such as soreness and swelling pain between the L4-L5-S1 spinous process, posterior iliac, posterior gluteal, inguinal, anterior femoral, posterior femoral and greater trochanter, aggravated by activity, especially after increased vertical spinal stress, unable to be in a sitting or standing position for long periods of time, lasting for more than 6 months, not accompanied by radiating pain in the lower extremities and intermittent claudication, without nerve root 2. X-ray examination did not reveal the presence of lumbar isthmic fracture, lumbar spine slippage and lumbar instability; 3. CT scan showed no lumbar disc herniation, lumbar spinal stenosis and other abnormalities; 4. MRI examination showed that the nucleus pulposus of the diseased disc showed low signal change in T2-weighted image; 5. lumbar discography showed rupture of the fibrous annulus, and the contrast agent had the nucleus pulposus at leakage to the outer 1/3 of the fibrous ring or the epidural space, which may induce replication of the same lower back pain as in the past.
