Ultra-minimally invasive treatment of lumbar intervertebral disc herniation Intervertebral foramenoscopy is an advanced minimally invasive spinal technology, and the Orthopedic Spine Ward of the East Hospital of the Municipal Hospital of Qingdao is the first one to carry out the lumbar intervertebral disc nucelus medullaris removing surgery under intervertebral foramenoscopy in Qingdao Orthopedic Surgery Field. The protruding disc can be clearly observed through the display and accurately removed. Meanwhile, the patient can communicate with the patient at any time to observe the patient’s response, and can go down to the ground immediately after the operation is completed, and can be discharged from the hospital in 3-5 days. Intervertebral foramenoscopy technology is mainly applicable to simple disc herniation, bulging or disc prolapse with serious neurogenic symptoms, and can also achieve better results for patients with intervertebral foraminal stenosis and mild spinal stenosis, and can also be used for the treatment of lumbar spine degenerative diseases that are not suitable for open surgery in the elderly. The treatment method has low risk, good efficacy and fast recovery, which truly embodies the concept of safer, more effective, more convenient, and the best surgical efficacy with minimal invasion and physiological interference. Lumbar disc herniation is due to the clinical symptoms of lumbar disc degeneration, rupture of the annulus fibrosus, herniated nucleus pulposus or prolapse of the nucleus pulposus compressing the nerve root or cauda equina. It is a common orthopaedic disease and the main cause of lumbar and leg pains, and it often brings a lot of pains to the patient’s life and work, and the serious cases even lose the ability to work. The main symptoms are: 1, lumbago is the first symptom of most patients, the incidence rate is about 91%. Due to the outer layer of the fibrous ring and the posterior longitudinal ligament is stimulated by the nucleus pulposus, through the sinus nerve and produce lower lumbar pain, sometimes accompanied by hip pain. 2, lower extremity radiating pain Typical sciatica is radiating pain from the lower lumbar region to the buttocks, the back of the thighs, the lateral calf until the foot, and the pain will be aggravated by sneezing and coughing and other cases of increased abdominal pressure. The radiating pain is mostly on one side of the limb, and only very rarely does the central or paracentral herniated nucleus pulposus show symptoms in both lower limbs. Some of them may be accompanied by numbness and burning sensation in the limbs. 3, cauda equina symptoms to the posterior protruding nucleus pulposus or prolapsed, free disc tissue compression of the cauda equina, its main manifestations for bowel obstruction, perineum and perianal sensory abnormalities. Limitation of lumbar activities The forward and backward flexion and extension activities of lumbar spine are closely related to the degree of disc herniation. If the annulus fibrosus is not completely ruptured, the lumbar spine takes the forward flexion position and the backward extension is limited. 5.Scoliosis Part of the patients will have lumbar spine bending to the left or right side, and touching the spinous process in the middle position on the back can find the spinous process is skewed. 6, claudication Mostly intermittent, that is, walking a distance away from the lower limb pain, weakness, bending or squatting to rest after the symptoms can be alleviated, still can continue to walk. Intervertebral foramenoscopy technology and advantages 1, high safety: local anesthesia, intraoperative interaction with the patient, does not injure the nerves and blood vessels, basically no bleeding, clear surgical field of vision, and effectively avoid the risk of mishandling. 2.Ultra-minimally invasive: the skin incision is only about 6mm, with minimal bleeding, short operation time, and almost no scar after operation, which is in line with the aesthetic point of view. 3.Precise: Lateral approach avoids the interference of posterior surgery on the spinal canal and nerves, does not bite off the vertebral plate, does not destroy the paravertebral muscles and ligaments, and has almost no effect on the stability of the spine. 4.Visualized operation: the protruding nucleus pulposus and nerve roots, dural sac and proliferated bone tissues can be clearly seen under direct endoscopic vision. 5.Fast recovery: the operation time is short, you can go down to the ground after the operation, the hospitalization time is about 3-5 days, and the average 3-6 weeks to resume normal work and physical exercise. 6, wide range of indications: can remove most types of disc herniation and prolapse, can deal with intervertebral foraminal stenosis and part of the spinal canal stenosis. 7.High satisfaction with the treatment effect: pain and other symptoms are relieved immediately after the operation, urination and defecation can be taken care of by oneself, and nursing is simple. The internationalized concept guides the rehabilitation and early return to normal life and work after the operation.
