Intervertebral foraminoscopy technology originated in Germany and the United States more than a decade ago and is now fully mature. Many domestic places such as Chongqing, Chengdu, Beijing and Zhejiang have been rapidly developed and generally achieved good clinical results. Since it is completely different from open internal fixation surgery and from the previous minimally invasive disc puncture surgery (non-direct nerve root decompression), it is a completely subversive technique in spine surgery and is the trend in the development of spine surgery technology. As laparoscopy is to general surgery, foraminoscopic surgery will also revolutionize spine surgery, especially lumbar disc surgery. However, it is difficult for older spine surgeons to relearn the technique because of the huge differences from general open surgery and also because of habit, so it is not successfully carried out in most tertiary hospitals. I was exposed to the change in technology 6 years ago, and I deeply understand and accept the intervertebral foraminoscopy technique. Endoscopic vision is clear and does not damage the nerves; endoscopic radiofrequency hemostasis and continuous saline irrigation ensure a clear surgical field and also basically avoid the risk of infection; 5. The rate of excellent surgical results is not lower than that of open surgery. Of course, in patients with severe foraminal stenosis, slippage, and high iliac bone, as well as in patients with severe bony stenosis, the puncture may not be successful and cannot be performed, but even so, there is no damage to the patient. There is also a risk that the canal will crush the exit root of the previous segment. And of course there is a recurrence rate.
