No matter what kind of surgery, the procedure is nerve-wracking and mysterious to the patient. Even if the doctor will explain in detail how the surgery is done and what the risks are, the patient still does not understand, and most of the mind is wondering whether the surgery is risky or not. Today, Dr. Yu Zhengrong of the Department of Orthopaedics at Peking University First Hospital will give the majority of patients to reveal the secret of the intervertebral foramenoscopy surgery is how to do? Intervertebral foramenoscopy is a diameter of less than 7mm hard hollow tube, surgery to use a variety of grasping forceps, radiofrequency cutter head, mirror grinding drills, etc., can be used through this tube to the body; hard tube child head has two small bulbs and cameras, to do the operation of the various corners of the light a clear, and displayed on the computer screen. Before the operation, the doctor will be based on a variety of test results, to determine where to “start” the most appropriate, usually in the side or back of the waist. The entire procedure is performed under fluoroscopy, which allows the surgeon to clearly see the location of the lesion (pictured). Typically, the surgeon makes a small hole in the side of the back and delivers the laminoscope to the location of the lumbar lesion. Then the surgical instruments to be used are threaded through this thin tube. These instruments include the nucleus pulposus forceps and radiofrequency electrodes. Nucleus pulposus forceps remove herniated discs, etc., so that the area where the nerves pass through is spacious and not pinched, and the symptoms of pain and numbness disappear; radiofrequency electrodes perform disc molding, hemostasis, etc., so that the operative field becomes clearer and the risk of recurrence is reduced. Intervertebral foramenoscopy surgery is not as bloody and scary as imagined. Compared with traditional open surgery, intervertebral foramenoscopy surgery is safer, the wound is only 6~8 millimeters, and there is only one suture after the surgery, which is less traumatizing and not easy to be infected, so there is no need for fluids after the surgery. Since the surgery is not under general anesthesia, patients can eat and drink immediately after the surgery, and can go down to the ground in two hours, and can be discharged from the hospital the next day if there are no special circumstances. Since there are no nerves in the intervertebral discs, only the small wound at the puncture site has a slight pain after the operation. Currently, the main lumbar spine diseases that can be treated by intervertebral foraminoscopic surgery are: lumbar disc herniation, intervertebral discogenic low back pain, disc herniation combined with lateral saphenous fossa stenosis, or intervertebral foraminal stenosis. However, patients with central spinal stenosis, which is often accompanied by thickening of the vertebral plates, joint hyperplasia and ligamentous thickening, are not suitable for laminectomy.
