Intervertebral foraminoscopy treatment of lumbar disc herniation: visualization, minimally invasive, fast postoperative results, is a new technology that major hospitals are competing to carry out in recent years. First, the adaptable population of intervertebral foraminoscopy technology in minimally invasive spinal surgery Patients with herniated discs who choose to undergo minimally invasive surgery must show signs and symptoms of nerve root compression and must meet the following conditions: 1. persistent or recurrent radicular pain; 2. radicular pain heavier than lumbago. Patients with less than moderate bulging who have more symptoms of low back pain than leg pain may first undergo low-temperature plasma myeloplasty; 3. Ineffective after strict conservative treatment. This includes the use of steroidal or nonsteroidal anti-inflammatory pain medications, physical therapy, homework, or conditioning procedures. Conservative treatment is recommended for at least 4-6 weeks, but if progressive exacerbation of neurologic symptoms occurs, then immediate surgery is required; 4. There is no history of substance abuse or psychiatric disorders; 5. Positive straight-leg raising test and difficulty in bending over; 6. In order to accurately determine the location and nature of the protruding or prolapsing nucleus pulposus, as well as the intervertebral foraminal osteophytes The operation should be preceded by a thorough imaging examination, especially CT and MRI are important means to accurately determine the size, location and nature of the nucleus pulposus. The basic principle of the operation is to remove the pressure on the nerve root and eliminate the pain caused by nerve compression by completely removing the protruding or prolapsed nucleus pulposus and hyperplasia outside the fibrous annulus of the intervertebral disc in the safe triangle of the intervertebral foramen. The procedure is performed through a minimally invasive spinal surgery system consisting of an intervertebral foraminoscope, corresponding surgical instruments, an imaging system, and a dual-frequency radiofrequency machine. While completely removing the protruding or prolapsed nucleus pulposus, it also removes osteophytes, treats spinal stenosis, and can use radiofrequency technology to repair broken rings. Third, the surgical steps can be specifically divided into nine parts 1, preoperative preparation need lumbar MRI to understand the morphology of the protrusion, lumbar DR to understand the intervertebral foramina and the height of the iliac spine; 2, marking the site of the needle General paracentesis distance of between 11-14 cm, and marked; 3, local anesthesia; 4, puncture and placement of the guidewire until the intervertebral disc; 5, intervertebral discography Using methylene blue and iodine seahydrol mixed ratio of 1:4 Inject 1-2 ml to dye the nucleus pulposus into blue color, which is easy to observe the morphology of the disc protrusion and remove it; 6, expand the intervertebral foramen step by step by grinding drill; 7, place the working trocars and intervertebral foramenoscope; 8, remove the stained protruding nucleus pulposus tissues and explore; 9, apply bipolar radiofrequency to eliminate the annulus fibrosus. Fourth, the choice of surgical access 1, simple disc herniation and part of the prolapse type cases, preferred posterior lateral safe triangle approach; 2, distal lateral level approach is suitable for the central huge type of herniation; 3, posterior or interlaminar approach is suitable for patients with free or calcified type. Fifth, the intervertebral foramenoscopy technology and orthopedic other treatment methods comparison It is understood that the technology through the special lateral intervertebral foramen access route, in the endoscopic surveillance to remove the herniated disc tissue, less traumatic than the usual posterior surgery. Typical laminectomies inevitably cause extensive damage to structures that play an important role in spinal stabilization in order to approach the target point, which usually requires immediate spinal fusion. In contrast, the laminectomy technique progressively enlarges the intervertebral foramina with a patented reamer and appropriate medical instrumentation, completely removing any protruding or detached fragments as well as the degenerated, inflamed nucleus pulposus. It also allows for continuous irrigation and anti-inflammation of the lesion, the use of radiofrequency electrodes to repair the fibrous ring, ablation of nerve sensitizing tissue, and blocking of the circumferential nerve branches to relieve the patient’s soft tissue pain.
