Intervertebral foraminoscopy is a safe and efficient minimally invasive procedure that removes the nerve-compressing disc nucleus pulposus under local anesthesia with an 8 mm skin incision using direct endoscopic vision, resulting in less trauma, faster recovery, and efficacy equal to or better than traditional open-heart surgery. The surgical indications are broad and can be used for the surgical treatment of most lumbar disc herniations. However, improper postoperative care and rehabilitation can affect the outcome of the surgery. The precautions after intervertebral foraminoscopy are: 1. Bed rest should be emphasized after intervertebral foraminoscopy Although strict bed rest is not required after intervertebral foraminoscopy, bed rest is also necessary and important. 2-5 hours after surgery should be strictly bed rest, do not go to the ground, which is mainly for the purpose of hemostasis within the wound to prevent the formation of hematoma. 4-6 weeks after surgery should be bed rest as much as possible, but you can get out of bed appropriately, 15 minutes each time, not too many times, in order to have no lumbar discomfort. Especially for patients who still have lumbar pain after surgery, huge protrusion or extensive bulging of the intervertebral disc need to pay more attention, bed rest can let the fiber ring fully repair and prevent the recurrence of leg pain caused by backward protrusion after narrowing of the vertebral space. 2, correct treatment of the recurrent period after intervertebral foraminoplasty (recovery period or edema period) A few patients have the so-called “postoperative reaction” after surgery, which is manifested by the reappearance of preoperative symptoms or even aggravation, or new symptoms can appear, such as numbness, pain, soreness and weakness. The duration can be very short or long, ranging from a few days to 3 months or even longer. The “recurrent phase” of symptoms occurs in approximately 30% of patients after surgery and can be reduced or avoided by strict adherence to medical advice. The symptoms of the recurrent phase of foraminotomy are varied, but generally manifest as back pain, hip pain, numbness, swelling, or soreness at the incision site on the affected side, or in a few cases on the opposite side. If the symptoms are not relieved by bed rest or continue to worsen progressively, 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 relapse or poor treatment, these can be self-recovery. 3, there is no need to rush to do imaging monitoring after intervertebral foramen surgery symptoms first improve, and then only to see the changes in the MRI, CT and other imaging, this is the so-called “imaging changes lag phenomenon” after the disc herniation surgery. The imaging changes usually normalize six months after surgery and are influenced by age, length of history, whether or not other excessive treatment was received, the degree of herniation, and the severity of the disease. Even in people with good surgical results, MR or CT examinations in the short term after surgery often do not show significant improvement. 4, the post-operative diet is generally not contraindicated, but Chinese medicine believes that it is best not to eat “hairy things”, such as mutton, seafood, etc.. 5, the following measures will help the patient’s recovery, otherwise the recovery process may be slowed down within 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 the hips with both 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, postoperative attention to review After disc hole surgery is generally in 1 month, 3 months, six months, 1 year after surgery to the hospital to review, 3 months or six months can do MR examination, to understand the recovery of the herniated disc after surgery. 7. If the recurrence of disc herniation is caused by various factors such as poor recovery and improper force, you can undergo minimally invasive surgery again because unlike open surgery, foraminal surgery will not form many scars in the surgical area to hinder the second surgery and increase the difficulty of the second surgery, so the second minimally invasive surgery of foraminal surgery will be as smooth as the first minimally invasive surgery.
