1, the basic precautions after intervertebral foraminoscopy patients need to have a certain amount of postoperative bed time: patients under local anesthesia during surgery bed is mainly to stop bleeding, 2-5 hours after the operation can be free to move. 2.correct treatment of the recurrent period after intervertebral foraminoscopy (recovery period or edema period) The so-called “postoperative reaction” will begin to appear on the third day after surgery, manifesting as the reappearance of preoperative symptoms, or even aggravation, or new symptoms, such as numbness, pain, soreness and weakness. The duration can be very short or very long, ranging from a few days to 3 months or even longer. About 30% of patients will have various symptoms in the “recurrent period” after surgery, which can be reduced or avoided by strictly following medical advice. 3, the performance of the recurrent period after intervertebral foramenoscopy The symptoms of the recurrent period of intervertebral foramenoscopy are various, but generally manifested as: lumbago, hip pain, numbness, swelling, or soreness at the incision site on the affected side, etc. There are also a few symptoms on the opposite side, most of which appear or are obvious when standing and sitting, and most of which can be relieved by themselves. If the symptoms are not relieved by bed rest or continue to worsen progressively, the MRI should be reviewed to see if endplate inflammation is present, and the treatment plan should be changed and the treatment period extended. The “recurrent period” is not a recurrence or poor treatment, these are self-recoverable. 4, the significance of routine medication after laminectomy The purpose of medication and rehabilitation within 3 months after surgery is to reduce or shorten the recurrence period, but there is no way to make all patients free from the “recurrence period”, please follow the doctor’s instructions for medication. 5, there is no need to rush to do imaging monitoring after intervertebral foramenoscopy Imaging changes lag is a common problem of open surgery, symptoms improve first after intervertebral foramenoscopy, and then you can see the MRI, CT and other imaging changes, this is the so-called “imaging changes lag phenomenon” of general orthopedic disease. Imaging changes are usually after six months, and the factors affecting this are mainly age, length of medical history, whether other excessive treatment has been received, degree of protrusion, severity of the disease, etc. 6, intervertebral foramenoscopy postoperative strict contraindications within 3 months after surgery shall not drink, shall not overwork, preferably do not eat “hairy things”, such as mutton, seafood, etc.; within six months shall not engage in long-term bending or prolonged squatting work or activities, such as long meetings, grass pulling, etc.; after surgery shall not be prolonged bed, bed time preferably not more than 10 hours. Otherwise, the symptoms are slow to ease; within six months shall not play computer games for a long time, Internet or long time playing cards; well, it seems to be very cruel, but it is all for the sake of patients, I hope that fellow doctors can communicate with or well. 7, advice to patients with intervertebral foramen surgery (1) You should keep in touch with your responsible doctor for 3 months after surgery in order to guide medication and rehabilitation exercises. (2) Medication: neurotrophic drugs, blood-strengthening drugs, anti-inflammatory and analgesic drugs, etc. are recommended for 3 months after surgery to facilitate the smooth passage of the “recurrent period”. (3) Regular follow-up: After the surgery, the patient should come back for follow-up at the third month, six months and one year. The content of the follow-up visit includes simple questioning, physical examination, imaging, etc. The content of each visit varies and is specific to each patient’s situation. (4) Regular follow-up: Each patient should return one year after surgery with preoperative imaging data to review MRI, CT, etc. (5) A review follow-up form should be filled out again one year after surgery for efficacy assessment. (6) Absolute bed rest without any exercise should never be allowed after surgery, otherwise there will be adverse consequences. (7) Post-operative rehabilitation should be carried out gradually and in accordance with medical advice, and if conditions permit, it should be transferred to the rehabilitation department. (8) Rehabilitation exercises can also be carried out by oneself, such as taijiquan, baduanjin and various gymnastics can be used as exercise programs.
