What are the differences between lumbar disc herniation treated with intervertebral foraminoscopy technology and traditional minimally invasive techniques such as nucleolysis, ablation, percutaneous myelotomy and aspiration and intervertebral discoscopy technology (from the analysis of treatment mechanism and effect)? 1. Traditional minimally invasive techniques are: (1) Chemical lysis: papaya rennin, collagenase myelolysis, ozone ablation. (2) Physical ablation: laser vaporization, low-temperature plasma, radiofrequency ablation, etc. (3) Percutaneous excision and aspiration: the puncture needle is located within the intervertebral disc to operate. All of them are radiologically positioned and operated within the intervertebral disc, so that the nerve structures cannot be seen, which belongs to indirect decompression within the disc, hoping to achieve decompression by herniating the disc invagination, which is unlikely, and at the same time cannot loosen the nerve root adhesions, and the indications are inclusive disc herniation and discogenic lumbago. However, for a long time, the indications have been expanded and applied to the treatment of non-inclusive disc herniation and spinal stenosis, failing to achieve the purpose and effect of decompression, leading to the belief that minimally invasive treatment of lumbar disc herniation is ineffective. 2, discoscopy technology and intervertebral foramoscopy technology: intervertebral foramoscopy technology is a technology for herniated nucleus pulposus removal and nerve decompression via percutaneous endoscopic access to the spinal canal under local anesthesia, which allows the R-causing material and the compressed dural sac and nerve roots to be seen under direct vision for complete decompression and to achieve the effect of open surgery. The surgical approach avoids damage to the paravertebral muscles while not destroying the stable structure of the spine. It is a minimally invasive treatment technique suitable for all types of disc herniation, allowing for both intradiscal and intradiscal management. The procedure is performed under local anesthesia and can be tolerated by elderly and elderly patients with multiple underlying diseases.
