In the treatment of lumbar disc herniation, “the least possible trauma” and “the best possible results” are often a contradiction. Intervertebral foraminoscopy is currently the best option to resolve this conflict. Compared to traditional surgery, foraminoscopy is a safe, efficient and minimally invasive treatment method, but improper postoperative care can affect the outcome of the procedure. So what are the postoperative precautions after foraminoscopy? 1, foraminoscopy requires a certain amount of time in bed after surgery: postoperative bed rest is mainly to stop bleeding, and you can move freely after 2-5 hours after surgery. Some experts also advocate that within 4-6 weeks after surgery, try to be bedridden, 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 low back pain after surgery, or patients with extensive bulging of the fibrous ring (often the opposite side had symptoms), which can allow full repair of the fibrous ring and help prevent the recurrence of leg pain caused by backward projection after narrowing of the vertebral space. 2. Correctly treat the recurrent period (recovery period or edema period) after intervertebral foraminoplasty. A small number of patients experience the so-called “postoperative reaction” after surgery, which is characterized by the reappearance or even aggravation of preoperative symptoms, or the appearance of 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. The symptoms of recurrent intervertebral foraminoplasty are varied, but generally manifest as back pain on the affected side, hip pain, numbness, swelling, or soreness at the incision site, etc. There are also a few symptoms on the opposite side, most of which appear or are apparent when standing or sitting, and most of which can be relieved on their own. If bed rest does not provide relief or if the symptoms continue to worsen progressively, 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 who have undergone foraminoscopy that the “recurrent period” is not a relapse or a poor outcome, but that these are self-recoverable. 3, the significance of routine medication after foraminotomy. 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 intervertebral foraminoscopy. The lag in imaging changes is a common problem in open surgery: symptoms improve first after laminectomy, and then imaging changes such as MRI and CT can be seen, which is the so-called “lag in imaging changes” in general orthopedic diseases. Imaging changes are usually seen after six months and are influenced by age, length of medical history, whether or not other excessive treatment has been received, degree of protrusion, severity of the disease, etc. Even in people with excellent surgical results, significant improvement is often not seen in MR or CT examinations within a short period of time after surgery. 5. There is generally no contraindication to the postoperative diet, but Chinese medicine believes that it is best not to eat “hairy things”, such as mutton, seafood, etc. The implementation of the following measures will definitely help the patient’s recovery, if the patient does not comply with medical advice may delay the recovery of the disease: 3 months after surgery, do not drink alcohol, do not overwork. Do not engage in long-term bending or prolonged squatting work or activities for six months, and do not sit for long periods of time (get down or lie down for 10 minutes every 30 minutes to one hour, or lift your hips with your hands on the chair surface for one minute every half hour). Washing clothes try to put the basin at chest height. Lift heavy objects no more than 10 kg and try to bend the legs without bending the waist. 6.If the patient recurs due to poor recovery, improper force and other factors, he can undergo minimally invasive surgery again because minimally invasive surgery, unlike open surgery, will leave a lot of scarring, which will hinder the second surgery or make the second surgery more difficult. The second minimally invasive surgery will be as smooth as the first minimally invasive surgery.
