The diagnosis of discogenic low back pain (with or without lower extremity pain) should be considered if CT or magnetic resonance imaging (MRI) reveals only mild disc herniation or no definite disc herniation or spinal stenosis, i.e., the clinical manifestations are not compatible with the examination. The lack of specific investigations and imaging manifestations makes its correct diagnosis very difficult. Discography is the most definitive test for the diagnosis of discogenic lower back pain. Minimally invasive plasma disc nucleoplasty can be performed at the same time as the angiogram for therapeutic purposes. The treatment principle of low-temperature plasma disc myeloplasty: under local anesthesia, a puncture needle (as thick as a syringe needle) is inserted into the intervertebral disc to vaporize and crumple the nucleus pulposus, which immediately reduces the pressure in the disc and effectively relieves the compression of the herniated disc on the nerve roots and spinal cord to eliminate and relieve clinical symptoms. At the same time, plasma cryogenic effect can also significantly improve the internal chemical environment caused by disc degeneration, inducing the synthesis of repair factors, which is conducive to local repair. Applicable groups: ① positive discography; ② disc height > 75%; ③ disc herniation, provided that the annulus fibrosus is intact (many patients who need discoscopic surgery or major open surgery but are not suitable for interventional treatment are commonly treated blindly with poor results, so the suitability needs to be strictly judged before surgery); ④ many types of cervical spondylosis, especially sympathetic cervical spondylosis.
