Why is it important for patients to rest, rehabilitate, and functionally exercise after minimally invasive endoscopic lumbar spine surgery? Because after microscopic removal of the nucleus pulposus tissue, although the neurological symptoms are relieved, the original ruptured fibrous annulus will take 4 to 6 weeks to repair. During this time. 1, the patient needs more bed rest, so that the fibrous ring in a state of rest in order to obtain recovery, 3 days after the operation, absolute bed rest. 2.To avoid atrophy of the low back, rehabilitation therapy and functional exercise will be started on the 3rd to 5th day, so as to restore the muscle strength of the low back and increase the muscle coordination, which will help to enhance the stability of the spine. 3.To avoid postoperative nerve root adhesion, it is recommended to start straight leg raising functional exercise on the first day after surgery and insist on it for 4 weeks. 4.Patients who want to get up to stand, sit, urinate and defecate must be protected by waist circumference fixation for about 1 month, and then get up again after tying it on the bed. 5.Rehabilitation exercise is best guided by the rehabilitation physician, if the patient can not cooperate with the above treatments, it may cause lumbar instability in the later stage, and the symptoms such as local hemorrhage, pain, numbness and so on will be aggravated. Therefore, patients should not think that they are symptom-free after the operation and the disease is cured, and the lumbar area should be carefully protected after the operation in order not to cause recurrence and consolidate the treatment effect. a, why some patients immediately after surgery, but 2-3 days later, began to appear back pain, leg numbness and other symptoms? The reason is that although the nerve is released from compression, local inflammation and hematoma stimulation of the nerve will appear 2~3 days after surgery, and then symptoms such as numbness and pain in the buttock area and legs will appear, and the inflammation of the nerve will subside slowly, and has to be eliminated gradually over a period of time. b. Will minimally invasive microscopic surgery recur? Minimally invasive microscopic surgery just bites off the herniated material and eliminates the nerve compression, and cannot rebuild the intervertebral disc to make the disc back to intact, only repairing, not replacing and rebuilding, so there is a possibility of recurrence. Even developmental surgery can cause recurrence in the segment or neighboring segments, but the doctor will be at his/her wit’s end if the herniation recurs after open surgery, whereas the doctor can still perform secondary treatment if the herniation recurs after minimally invasive surgery.
