With the accelerated pace of life, more and more people suffer from lumbar disc herniation because of poor living or working habits, and its incidence is currently showing a high-speed upward trend, according to the Ministry of Health statistics, China’s lumbar spondylosis patients have exceeded 200 million people, the lumbar disc herniation patients accounted for 15.2% of the country’s total number of people. Over the years has been a rising trend, and year by year at an alarming rate by the middle-aged and elderly to the expansion of young adults. Often hear people around with lumbar herniation complain of back and leg pain, but are afraid of the trauma of traditional surgery and the many complications, there is no a less traumatic, shorter course of treatment, less risky, faster recovery, low recurrence rate of the method? Intervertebral foramenoscopy technology brings gospel to the majority of patients with lumbar synostosis. Figure 1 Intervertebral foramenoscopy operation What is intervertebral foramenoscopy technology? It is similar to a spinal endoscope, a minimally invasive surgical working channel equipped with a cold light source. It enters the intervertebral foramen from the side or back of the patient’s back and completely removes the protruding or prolapsed nucleus pulposus and hyperplastic bone outside of the intervertebral foramen’s safety triangle and the intervertebral disc fibrous annulus in order to decompress the nerve root and eliminate the pain due to the compression of the nerves. The surgery is accomplished through a minimally invasive spinal surgery system consisting of specially designed channels, intervertebral foraminoscopes, complementary minimally invasive spinal surgical instruments, imaging and image processing systems, and so on. During the surgery, complete removal of the protruding or prolapsed nucleus pulposus can be realized, as well as removal of osteophytes, treatment of spinal stenosis, and repair of broken annulus fibrosus with radiofrequency technology, among other operations. Figure 2 Intraoperative management of the nucleus pulposus (A. protruding nucleus pulposus; B. occlusion of the nucleus pulposus; C. nerve root reduction. The arrow shows the nerve root seen during surgery; the red triangle shows the dislodged nucleus pulposus). What are the advantages of intervertebral foraminoscopy? First, compared with the traditional open nucleus pulposus removal surgery, the surgery is performed under local anesthesia, and the patient can be communicated with at any time during the surgery; second, the surgery is less traumatic: the skin incision is only 7mm, like the size of a soybean grain, with less than 20ml of bleeding, and the wound is only 1 suture; third, compared with the posterior discectomy technique (MED), which has been widely recognized in recent years, MED, although it can be applied to various types of lumbar disc herniation, is not as effective as the other techniques because of its surgical access to the lumbar discs. Thirdly, compared with the widely recognized posterior discoscopy technique (MED) in recent years, although MED can be applied to all kinds of lumbar disc herniation, its minimally invasive nature is limited due to the fact that its surgical access and surgical procedure are the same as that of small-incision open surgery, which requires paraspinal muscle access and implementation of vertebral plate opening and resection of the musculoligamentous and osseous structures, and therefore destroys more tissue. Compared with the intervertebral foraminoscopic technique, it has obvious advantages such as less trauma, less bleeding, easier anesthesia, faster postoperative recovery, and lighter economic burden. Fourth, compared with the existing minimally invasive spinal methods such as nucleus pulposus mechanical excision and decompression, chemical nucleus pulposus dissolution, or indirect decompression techniques such as laser vaporization, the foraminoscopic disc removal is directly targeted at removing the protruding disc fragments and decompressing the nerve roots in the magnified image, and therefore the decompression effect is more direct. Therefore, the decompression effect is more direct and thorough. Therefore, the decompression effect is more direct and thorough. In a real sense, it realizes less trauma, shorter operation time, less risk, faster recovery and lower recurrence rate.

The minimally invasive spine ward of our spine surgery department took the lead in introducing the maxMorespine intervertebral foraminoscope produced by Hoogland spine products GmbH of Germany, and at the same time invited experts from other hospitals to our hospital for academic exchanges and surgical demonstrations for many times. The minimally invasive spine ward has successfully carried out many cases of foramenoscopic surgery, and the patients’ back and leg pain is significantly improved at the end of the surgery, and they can go down to the ground one day after the surgery, and can be discharged from the hospital in 2-3 days, which is well received by the patients and their families. With the wide application of this technology, it will make our hospital’s technology for treating spinal degenerative diseases and other spinal disorders more advanced and mature; at the same time, this technology will also become an important means of lumbar disc herniation treatment, which provides patients with more diversified options.
