There are many minimally invasive spine techniques in clinical practice, which roughly boil down to minimally invasive ablation of intervertebral discs, spinal endoscopic techniques, and percutaneous internal fixation techniques. With the promotion of minimally invasive techniques in clinical practice, the concept of minimally invasive technology is currently confusing in China, as people think that a small incision is minimally invasive. In fact, minimally invasive spine is completely different from the traditional understanding of minimally invasive laparoscopy. The two vertebral joints and intervertebral discs of the spine are called a functional unit of the spine, and the loss of spinal stability and disc function cannot be called minimally invasive in the true sense of the word. Therefore, the loss of spinal motor function by percutaneous internal fixation, which is promoted clinically, cannot be called minimally invasive; posterior discoscopy and nucleus pulposus removal under dilated access are not minimally invasive in the true sense. Therefore, only spinal endoscopic techniques can be used to decompress the nerve and remove the nucleus pulposus through the intervertebral foramen of the spine without destabilizing the spine and without losing the motor function of the segment. At present, when we encounter some young patients with herniated discs, doctors will promote the use of minimally invasive decompression fusion and percutaneous internal fixation techniques, which are superficially less invasive and recover quickly after surgery, but the postoperative loss of motor function of the segment, lumbar spine activities and increase the risk of degeneration of adjacent segments, and even more so for patients around 20 years old, the technology will be used, and later the patient will have to experience labor, sports and other daily life, which will more or less bring functional limitations. It will bring some functional limitation.
