TV foraminoscopy is currently the most advanced minimally invasive treatment for herniated discs. Our center has successfully relieved the pain of many patients with lumbar disc herniation by applying the internationally advanced minimally invasive spine technology – technology TV under foraminoscopy. Minimally invasive intervertebral foraminoscopy technique: The purpose of minimally invasive intervertebral foraminoscopy technique is to relieve the pressure on the nerve roots and eliminate the pain caused by nerve compression by completely removing the herniated or prolapsed nucleus pulposus and hyperplastic bone outside of the intervertebral foramen safety triangle and intervertebral disc fibrous ring. The procedure is performed through a minimally invasive spine surgery system with a specially designed intervertebral foramoscope and the appropriate supporting minimally invasive spine surgical instruments, imaging and image processing systems. The procedure is performed under local anesthesia with a tiny skin incision while the patient is awake, and the herniated degenerated nucleus pulposus is removed under the foramoscope with minimal trauma, without destroying the paravertebral muscles and ligaments and without affecting the stability of the spine. While completely removing the herniated or prolapsed nucleus pulposus, it also removes osteophytes, treats spinal stenosis, and can repair the broken annulus fibrosus using radiofrequency technology. Because the foraminoscopic spine technique is performed outside of the annulus fibrosus, the integrity of the annulus fibrosus can be maintained to the greatest extent and the stability of the spine can be preserved, giving the best results of any procedure of its kind. The advantages of the minimally invasive foraminoscopic spine technique: The minimally invasive foraminoscopic spine technique is a well-established and proven technique that was developed by renowned German spine surgeon Tom Huland and others who have performed more than 1,000 procedures. It was introduced to the world by the famous German spine surgeon Tom Huland and others after performing over a thousand successful procedures. It has some major advantages: the patient requires only local anesthesia, not general anesthesia. The surgery is performed while the patient is fully awake. The patient’s reaction can be detected at any time during the surgery. The surgical site is reached through a very small percutaneous incision, minimizing the risk of infection during and after surgery. Unlike microsurgical techniques, the foraminal approach does not require partial removal of the intervertebral ligaments (ligamentum flavum), conus or intervertebral joints (conus laminectomy) in order to locate and remove the herniated or prolapsed nucleus pulposus. It also does not require severance of the trunk muscles, increasing postoperative stability and reducing wound healing pain. Less bone tissue is injured, reducing blood leakage and scar formation in the nerve root area. Quick recovery after surgery allows patients to return to work and ensure a high quality of life as soon as possible. The unique design of the cannula and surgical instruments allows for the discovery and protection of the nerve roots, protection of the epidural and perineural venous system, prevention of venous stasis and chronic neuroedema. In addition, it can reduce perineural and epidural scar formation. It does not damage the good dural and nerve ligament structures and reduces the occurrence of nerve root tethering. The use of a working trocar can reduce paravertebral muscle injury and loss of innervation. In contrast, stripping and pulling of the paravertebral muscles during open surgery often damages the paravertebral muscles and denervates the muscles. In addition, postoperative segmental instability and slippage can be prevented. In accommodative disc herniation, intra-vertebral disc surgery decompression surgery protects the integrity of the posterior annulus fibrosus and posterior longitudinal ligament, thereby reducing the chance of recurrence of postoperative disc herniation. Published international literature has reported success rates of more than 90% at 1 and 2 years postoperative follow-up, with early recurrence rates of less than 5%. In patients with recurrence, the success rate exceeds 84%. Minimally invasive intervertebral foraminoscopic spine technique represents a new concept of minimally invasive surgery. It can perform herniated discs, foraminoplasty and annulus fibrosus repair in all segments from the cervical spine to lumbar 5 and sacral 1. The satisfactory outcome of the surgery can reach 75-90%. Because of its many advantages, the international field of spine surgery has now recognized that foraminotomy will become as dominant in the field as the well-developed arthroscope. Indications for minimally invasive foraminoscopic spine surgery 1. persistent or recurrent radicular pain. 2. Root pain heavier than lumbar pain. If the symptoms of lumbar pain are greater than the leg pain of patients with moderate or less bulging can first do cryoplasty of the nucleus pulposus. 3.Invalidated by strict conservative treatment. Including the use of steroidal or non-steroidal anti-inflammatory painkillers, physical therapy, homework or condition training procedures, conservative treatment is recommended for at least 4-6 weeks, but if there is a progressive worsening of neurological symptoms, immediate surgery is required. 4. No history of substance abuse or psychological disorders. 5, Positive straight leg raise test and difficulty bending. 6, In order to precisely determine the location and nature of the herniated or prolapsed nucleus pulposus, as well as intervertebral foraminal osteophytes, a thorough imaging examination should be performed before surgery, especially CT and MRI are important to precisely determine the size, location and nature of the nucleus pulposus. 7. Evidence of neurological injury or positive electromyography.
