In conventional lumbar disc herniation, the nucleus pulposus compresses the lumbar nerve and shows signs and symptoms of paralysis of the cauda equina nerve branch, which can involve 1 segment, 2 segments or even 3 segments, and less frequently, segments; there is also lateral and bilateral nerve root compression, and the signs and symptoms of its nerve compression are more numerous and widespread Modern imaging can show single-segment and multi-segment onset. However, it is common for only 1 or 2 segments to have signs and symptoms of true nerve compression. The imaging of the lumbar spine, whether X-ray or CT, MRI, the posterior sequence of the vertebral body is still good, the small joint alignment is normal, indicating that the stability of the segment of the spine is good, simply remove the herniated pulpal nucleus to obtain satisfactory results, no need to use intervertebral fusion. 1, the indications for intervertebral fusion In the above-mentioned cases, combined with the same segmental spinal instability or Ⅰ ° slippage, the fusion device placed between the vertebral body is necessary and correct. When the lumbar hyperextension and hyperflexion radiographs show slippage of II° and above, note that the pedicle may be disconnected, fractured (old), or severely hyperplastic, even if the herniated nucleus pulposus is removed and an intervertebral fusion implantation is performed, it is still not helpful, and a posterior lumbar pedicle nail rod (plate) system should be taken to reposition and fix the lumbar spine, while Cage is implanted to fuse the segment, which is an unavoidable action, in order not to aggravate the dislocation and affect Lumbar spine activities and quality of life. 2, blind implantation of intervertebral fusion in addition to the above-mentioned unprincipled implantation of Cage, in recent years, there are also attempts to remove the herniated nucleus pulposus of the lumbar disc in the posterior approach with the aid of instruments in minimally invasive surgery tide, the creation of fusion with transscopic implantation, and even implantation of segmental fusion, and that it should be considered as “routine” standardized surgery, which is not based on. There are also people who “routinely” implant lumbar interbody fusion or scrape the upper and lower cartilage endplates for autologous + allogeneic preparation bone implant fusion when removing the herniated nucleus pulposus in the posterior approach is also unnecessary. Unknown to the public, this blind fusion fusion fusion of the lumbar spine brings harm: (1) more vertebral segment loss of function; (2) promote the neighboring vertebrae degeneration, lumbar spine function gradually restricted, and the expansion of the neighboring vertebrae of the neighboring vertebrae; (3) surgery endanger the prevertebral, paravertebral vascular nerve risk increases; (4) fusion or other implants slip into the spinal canal caused by compression within the spinal canal. An important reason for this is that this implant fusion is nonphysiological and the adverse consequences of rapid degeneration 2 to 3 years after surgery extend rapidly to the adjacent vertebrae. When a lumbar disc herniation is accompanied by lumbar instability and Ⅰ° slippage without fusion implantation fusion of the lumbar spine, it is bound to be subjected to the pressure of recent reoperation. Conventional lumbar disc herniation nucleus pulposus can be removed through a 2-3 cm incision and intervertebral bone window, and rarely requires laminectomy on one side and then removal of the nucleus pulposus, much less total laminectomy to remove the herniated nucleus pulposus. Doctors who expand fusion because of the potential for late spinal instability associated with a hemilaminectomy or total laminectomy should consider improving your procedure and not trying to save time by completing a procedure that could have been done with a window via total laminectomy. It may not always be necessary to perform interbody fusion after laminectomy for a condition such as total laminectomy. Orthopaedic surgeons should have access to norms and good professional conduct. 3, from excessive surgery can not correctly grasp the indications for surgery, unprincipled expansion of the scope of surgery, is excessive or excessive surgery, from personal performance, the blind pursuit of intervertebral fusion cases, or another impure other figure. Our doctors must not be tainted with a little, but must work for the long-term interests and health of the patient. Excessive and excessive surgery is a different concept from artificial disc replacement or artificial nucleus pulposus replacement in patients with lumbar disc herniation with intervertebral disc disease, both of which originate from new methods created in recent years in China and abroad and have their own unique efficacy, although some problems are still being improved. Artificial disc replacement can obtain the efficacy of the movable disc, the neighboring spine will not accelerate degeneration, and there is no recurrence problem, but the surgical trauma is enlarged. Artificial nucleus pulposus replacement has been carried out in a few hospitals for many years, and the recent efficacy is still good, but the long-term efficacy needs further observation. We sincerely hope that more and better treatments will be available to patients.
