1. What is intervertebral foraminoscopy? Simply put, intervertebral foraminoscopy is an endoscopic technique using water as the medium, and similar techniques such as arthroscopy. By making a 7 mm incision on the surface of the body, a 7.1 mm diameter channel is placed on the surface of the herniated disc, and the herniated disc is removed by grasping the forceps, freeing the compressed nerve roots and relieving the symptoms of back and leg pain. 2.Which is better, “minimally invasive” intervertebral foraminoscopic surgery or “nail-biting” surgery? A herniated disc is a slowly developing and gradually aggravating process, generally when the degree of herniation is heavy and requires surgery, at this time our discs are divided into discs that have degenerated and herniated, discs that are degenerating and discs that are relatively normal. The so-called “minimally invasive” foraminoscopic surgery is to remove only the herniated disc and part of the degenerating disc, while preserving the relatively normal disc. After all the discs are removed, the vertebral body loses its connection structure and needs to be fixed with metal nails. Therefore, it is impossible to say which of the two surgeries is better, but they are both standard surgical methods for treating lumbar disc herniation. 3. Does “minimally invasive” foraminoscopy mean that it is not clean and prone to recurrence? As mentioned above, foraminoscopic surgery only removes the disc that has degenerated and protruded, about 5% of the disc is removed and 95% of the relatively normal disc is retained, without destroying the stability of the remember, so there is no need for nailing, but part of the 95% normal disc will continue to degenerate, so there is a “recurrence”. This said, in fact, should not be called “recurrence”, but “new” protrusion, the proportion of about 5% in 5 years. 4. I heard that intervertebral foraminal surgery is particularly painful? No. Any surgery is performed to ensure safety and to pursue efficacy, because there are nerve roots in the intervertebral foramen, so we use local anesthesia to avoid damaging the nerve roots, because of this, the patient is completely awake during the surgery, and some patients have intraoperative pain due to poor pain tolerance. 5.How should I exercise after laminectomy? Generally, we require 6 hours after surgery to move on the ground, and wear a peri-waist for two weeks after surgery, and the specific actions are described in the missionary manual. 6.Can I do it again if I have a recurrence after laminectomy? Yes, the biggest advantage of intervertebral foraminoscopy is that there is very little surgical scar and the herniated nucleus pulposus can continue to be removed along the original surgical channel. Moreover, since the approach of foraminotomy is completely different from that of open surgery, it does not affect the open surgery even if it is done later. 7.Why does my leg still hurt after laminectomy? This is not a relapse, but a recovery process of the nerve roots themselves, which will disappear slowly in about 1-2 months.
