Clinically, we often encounter some patients complaining of low back pain, occasionally radiating to the buttocks and legs, but it is not clear to which specific piece, especially when the imaging (lumbar spine CT and MRI) and no obvious signs of lumbar disc herniation compressing the nerve, then we should consider “discogenic pain”. The clinical characteristics of discogenic lumbar pain: 1. Sedentary inability is a common complaint, and the pain increases when sitting and leaning forward, especially when sitting in a leaning forward position. 2. The site of pain is generally confined to the midline region of the lower back and often radiates to the buttocks and both lower limbs. The lumbar 3-4 interval often radiates to the front of the calf, but not to the back of the lower limbs; the lumbar 4-5 is mostly limited to the front of the thigh, which may or may not be accompanied by pain in the back of the thigh or calf; the lumbar 5 sacral 1 is often located behind the large and small legs. The pain in the hip, hip, groin area or lower extremity may come from the posterior fibrous annulus lesion of the intervertebral disc without involving the nerve roots; 3. The duration of pain. It is persistent, resting pain, but it is more aggravated after physical activity, but it is often not relieved immediately when resting in a recumbent position; 4. Nature of pain. It lacks specificity and is self-induced distension. The reactive pain in the lower extremities is different from the radiating pain of lumbar disc herniation, and there are no positive features of nerve root damage on physical examination. 5. There is deep pressure pain at the spinous process on physical examination, and paraspinal pressure pain is not obvious. Diagnosis: Discography is currently the only method that can confirm the diagnosis and guide the next step of treatment. If the patient has pain similar to the usual site, nature, and degree of the attack, it is called “consistent pain” (concordant pain). The patient should be taken to the discography suite (CT discography) within 2 hours of the injection, otherwise the contrast may have disappeared. There is a low signal change on the MRI T2 image. Treatment of discogenic low back pain includes conservative and surgical treatment. Conservative treatment includes bed rest, traction, massage, lumbar compression, and medication. Half of the cases have been reported in the literature to have gradual symptom relief after 5 years. If symptoms are recurrent, persist for more than 1 year, discography is positive, and conservative treatment is ineffective, removal of disc implant fusion can be considered to stabilize the spine.
