Low back pain is pain or discomfort in the lumbosacral region below the 12th rib and may be accompanied by painful discomfort in the lower extremities. The global prevalence of low back pain is 9.17% and is age and gender dependent, with a sharp increase in prevalence between the ages of 30-60 years and a higher prevalence in women than in men. Of particular concern is the fact that the prevalence is higher in economically high-income areas than in poorer areas. Thus, low back pain is a serious public health problem in modern society. Discogenic low back pain is low back pain caused by self-inflicted lesions of the lumbar intervertebral disc and is characterized pathologically by the growth of vascularized granulation tissue and painful nerve fibers along the radiolucent fissures of the intervertebral disc fibrous ring. Discogenic pain accounts for 39% of low back pain, and lumbar disc herniation accounts for 30% of low back pain, so lumbar disc pathology is the most important cause of low back pain, and the majority of low back pain problems arise from the intervertebral disc. The Disc-FX system, which uses a smaller channel (3 mm in diameter) than the working channel (7-8 mm in diameter) of an intervertebral foraminoscope, integrates three technical operations – nucleus pulposus removal, radiofrequency ablation and fibrous annuloplasty – in a single operation, and is highly effective in the study of the pathogenesis of lumbar pain and new treatment technologies. The advantage of this technique is that it achieves multiple objectives in one operation, is done under local anesthesia, can greatly reduce the operation time and cost, and has the same excellent results as discoscopy and conventional open surgery, but with minimal trauma and is much safer and easier.
