Lumbar disc herniation is a common disease in orthopedics, and it is the most common cause of back and leg pain. Director Wang Yansong adopts individualized treatment plan for the type and severity of lumbar disc herniation, adheres to the humanistic care concept of being able to be simple but not complicated, non-invasive but not minimally invasive, and minimally invasive but not open, and scientifically summarizes the use of ladder synthesis and tailor-made treatment for various types of lumbar disc herniation. Minimally invasive intervertebral foramoscopy technology is currently the most advanced and minimally invasive surgery recognized in the field of international spine surgery for the treatment of herniated discs. All operations are visualized, avoiding nerves, with high safety and satisfactory results. Because of the expensive equipment and high technical requirements, few hospitals in the province are currently performing this technique. During the operation, the intervertebral foramen is precisely located under the guidance of the C-arm, and the herniated nucleus pulposus is removed under image surveillance by entering the spinal canal through an incision of about 7 mm on the skin surface. During the operation, communication with the patient was maintained, so that the stimulation of the nerve could be detected at the first time, and the safety factor of the operation was extremely high. The protruding nucleus pulposus was removed during the operation, and the patient felt that the pain in the lower limbs disappeared at that time, and the straight leg raising test was negative immediately on the operation table. After the operation, the patient can walk on the ground properly and the hospital stay is greatly shortened. The selection criteria for intervertebral foraminotomy or endoscopic microdiscectomy are similar to those for laminectomy and disc removal. Patients with herniated discs selected for minimally invasive surgery must exhibit signs and symptoms of nerve root compression and must meet the following conditions: 1. Patients with lumbar disc herniation with first onset, severe pain in the lower extremities, difficulty walking, difficulty sleeping at night, and unsatisfactory results after conservative treatment. Or persistent or recurrent radicular pain; 2. Invalidated by strict conservative treatment. This includes the use of steroidal or non-steroidal anti-inflammatory pain medications, physical therapy, and occupational or conditioned training procedures, and conservative treatment is recommended for at least 4-6 weeks, but immediate surgery is required if there is a progressive worsening of neurological symptoms; 3. No history of substance abuse or psychological disorders; 4. Positive straight leg raise test and difficulty bending; 5. In order to precisely determine the location and nature of the herniated or prolapsed nucleus pulposus and the intervertebral foraminal osteophytes situation, a thorough imaging examination, especially CT and MRI, should be performed before surgery to accurately determine the size, location and nature of the nucleus pulposus. Advantages of intervertebral foraminal therapy 1. The target area is reached through a lateral-posterior approach, avoiding interference with the spinal canal and nerves from traditional surgery and having almost no effect on spinal stability; 2. The nerve root is the direct target, rather than a target point, and all tissue structures that interfere with the nerve root and dural sac are removed and treated, expanding their space of movement along the nerve root path; 3. It can deal with almost all types of disc herniation and can treat bony lesions such as foraminal stenosis, disc and posterior longitudinal ligament calcification that were difficult to deal with in the past. Endoscopically, special electrodes are used and fibrous annuloplasty and annular nerve branch block are feasible to treat discogenic low back pain; 4. Less complications. The possibility of posterior surgery damaging the cauda equina is avoided, and the incidence of postoperative pain is significantly reduced; 5. High safety. Local anesthesia surgery, intraoperative interaction with the patient, no injury to nerves and blood vessels, basically no bleeding, clear surgical field of view, significantly reducing the risk of misoperation. It is especially suitable for elderly patients who cannot receive major surgery due to underlying diseases; 6. Fast recovery. After surgery, you can go down to the ground and resume normal work in 2-3 weeks on average, and resume general sports activities in 6 weeks; 7, high satisfaction. Immediately after the operation, the discomfort is relieved and the individual lives on his own, and the care is simple. The skin incision is only 6-8mm, with fast healing and low risk.
