In the treatment of lumbar disc herniation, “the smallest possible trauma” and “the best possible result” are often a contradiction. Intervertebral foraminoscopy is the best choice for solving this contradiction. Compared with traditional surgery, laminectomy is a safe and efficient minimally invasive treatment, but if the postoperative care is not appropriate, it will affect the results of the surgery. Then what are the postoperative precautions after intervertebral foraminoscopy?1, foraminoscopy needs to have a certain amount of bedtime after surgery: postoperative bedtime is mainly to stop bleeding, and you can move freely after 2-5 hours after surgery. Some experts also advocate 4-6 weeks after surgery, try to stay in bed, but also need to get out of bed properly, generally 8 times a day, 15 minutes each time. This method is of greater significance to patients who still have postoperative low back pain, or fibrous ring extensive bulging type (often contralateral had symptoms), which can let the fibrous ring fully repair, and help to prevent the narrowing of the intervertebral space after the backward projection caused by the recurrence of leg pain. 2, correctly treat the recurrent period after intervertebral foramenoscopy (recovery or edema period). A small number of patients have the so-called “postoperative reaction” after surgery, which manifests itself as the reappearance or even aggravation of preoperative symptoms, or the appearance of new symptoms, such as numbness, pain, soreness and weakness, etc. The duration can be short or long. The duration can be very short or very long, ranging from a few days to 3 months or even longer. About 30% of the patients will experience “recurrent” symptoms after surgery, which can be minimized or avoided by strictly following the doctor’s instructions. Symptoms of the recurrent phase of laminectomy are varied, but generally manifest as: low back pain on the affected side, pain in the buttocks, numbness, distension, or soreness at the incision site, etc. A few patients have symptoms on the opposite side of the body, and most of them appear or become obvious when standing or sitting, and most of them can be relieved on their own. If bed rest does not provide relief or if the symptoms continue to worsen in a progressive manner the MRI should be reviewed to see if endplate inflammation is present, at which point the treatment plan will have to be changed and the treatment period will be extended. We need to communicate with patients undergoing laminectomy that the “recurrent period” is not a relapse or poor efficacy, but that these can be recovered on their own.3. 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”, so please follow the doctor’s instructions for medication. 4. There is no need to rush to do imaging monitoring after laminectomy. The lagging of imaging changes is a common problem of open surgery: the symptoms first improve after laminectomy, and then the imaging changes such as MRI and CT can be seen, which is the so-called “lagging phenomenon of imaging changes” in general orthopedic diseases. This is the so-called “imaging lag” in general orthopedic diseases. Imaging changes usually occur after six months, and the factors that affect this are age, length of medical history, whether or not the patient has received other over-treatment, the degree of herniation, and the severity of the disease. Even for people with good surgical results, MR or CT examinations often do not show significant improvement in the short term after surgery. 5. There are no contraindications to diet after laminectomy, but Chinese medicine practitioners believe it is best to avoid “hairy foods” such as mutton and seafood, etc. The following measures will definitely help patients. The implementation of the following measures will definitely help the patient’s recovery, if the patient does not comply with the medical advice may delay the recovery of the condition: 3 months after the operation, no alcohol, no overwork. Do not engage in work or activities that involve prolonged bending or prolonged squatting for half a year, nor should you sit for long periods of time (get down or lie down for 10 minutes every 30 minutes to 1 hour, or lift your buttocks with your hands on the chair for 1 minute every half hour). Try to wash your clothes with the basin at chest height. Lift no more than 10 kilograms of heavy objects and try to bend the legs without bending the waist.6. If the patient has a recurrence due to various factors such as poor recovery and improper exertion, he/she can undergo minimally invasive surgery again, because minimally invasive surgery is not like the open surgery which will leave a lot of scars that will hinder the second surgery or increase the difficulty of the second surgery. The second minimally invasive surgery will go as smoothly as the first.
