Percutaneous intervertebral foraminoscopic nucleus pulposus removal and nerve root release

  Under the leadership of Director Wang Hongchen, the Minimally Invasive Spine Working Group of our orthopedic department successfully carried out 100 cases of minimally invasive percutaneous foraminoscopic nucleus pulposus removal and nerve root release for lumbar disc herniation with lumbar spinal stenosis. The patient was able to get up independently from the operating table and walk on the floor immediately after the operation, and her back and leg pain and numbness were almost completely relieved, and she was quite satisfied with the efficacy of the operation.  Percutaneous intervertebral foraminoscopic nucleus pulposus removal and nerve root release is called “the most minimally invasive and gentle treatment for lumbar disc herniation” in the medical field.  This technology can treat all types of lumbar disc herniation, from inclusive lumbar disc herniation to huge nucleus pulposus free in the spinal canal and most of the lumbar spinal stenosis (sagittal diameter of spinal canal >11mm). Compared with traditional surgery, foraminoscopic surgery has many advantages, such as the skin incision is only 5-7 mm, bleeding is minimal; local anesthesia, intraoperative interaction with the patient, not easy to injure the nerve; posterior lateral approach, avoiding the posterior surgery on the dural sac and nerve root harassment; foraminoscopic surgery can be the patient down to the ground, recovery is fast; long-term recurrence rate and infection rate is low.  Lumbar disc herniation, commonly known as lumbar leg pain, is a common and frequent disease in orthopedics. Degeneration, trauma and other factors can lead to lumbar disc herniation, lumbar spinal stenosis, compression of nerve roots, causing low back pain, lower limb radioactive pain and numbness, intermittent claudication, etc. According to statistics, there are about 200 million patients with lumbar disc herniation in China, with an incidence rate of 15.2%. In the past, the treatment of lumbar disc herniation was usually performed by traditional open surgery, with a median approach to the lumbar back and laminectomy and nucleus pulposus removal after stripping the paravertebral muscles. This procedure is more invasive and can destabilize the spine. Later, the procedure was developed into discoscopic nucleus pulposus removal, but it still requires partial removal of the vertebral plate, which also destabilizes the intervertebral space. In recent years, the United States and Germany have pioneered percutaneous intervertebral foraminoscopic surgery, which is performed through an enlarged intervertebral foramen pathway and operated under direct endoscopic vision, so that the anatomical structure levels of the herniated nucleus pulposus, fibrous ring, nerve roots, dural sac and hyperplastic bone tissue, posterior longitudinal ligament, and ligamentum flavum are clearly presented on the screen with greater safety. The special bendable bipolar radiofrequency electrodes provide good hemostasis and ablation of adhesions for a clearer view during surgery; they can also be used to perform annuloplasty and destroy pain-causing peripheral nerves on the intervertebral disc. This technique does not bite off the vertebral plate, does not destroy the paravertebral muscles and ligaments, has no effect on the stability of the spine, and does not require internal fixation with bone graft fusion.  In addition to percutaneous intervertebral foraminoscopy, our orthopedic department also performs minimally invasive treatment of simple inclusive and subligamentous lumbar disc herniation and mild to moderate cervical spondylosis with low-temperature plasma radiofrequency ablation.
