Lumbar disc herniation is a common cause of low back pain in young and middle-aged people, the general condition of the patient after conservative treatment is cured or improved, but for about 5% of the patients, recurrent low back pain, formal conservative treatment for more than 6 months is ineffective; or neurological compression symptoms progressive aggravation of the feasibility of surgical treatment. Previous surgical methods are generally performed after partial laminectomy to remove the protruding nucleus pulposus; for the combination of lumbar instability and even need to perform bone graft fusion. The former surgical method, due to the height of the intervertebral space is reduced after the removal of the intervertebral plate, postoperative degeneration can lead to aggravation or make the ligaments in the spinal canal tortuous and make the dural sac soft compression, causing lumbar and leg pain of medical origin. The latter surgical method, relatively traumatic, has a large impact on lumbar spine function, due to the loss of the original function of the fusion segment, lumbar spine mobility is reduced, lumbar stiffness and other undesirable complications. At present, the newly developed interspinous non-fusion fixation technology at home and abroad is a new treatment method for patients with lumbar intervertebral disc herniation requiring surgical treatment. The representative interspinous implants mainly include Wallis and Coflex, which are mainly used in the segment of interspinous disc herniation, after removing the interspinous disc (or even without dealing with the interspinous disc), to put interspinous bracing and fixation device into the interspinous process of the interspinous process of the interspinous process of the interspinous section, so as to change the abnormal transmission of lumbar vertebral loads caused by the removal of the interspinous disc, and to limit the undesirable loads, and to maintain the proper transmission of the normal loads. This method is less traumatic, the implant can be stored in the body for a long time, and it does not affect the further treatment (such as lumbar fusion). Therefore, this surgical method is widely practiced by professionals at home and abroad.
