I. Can lumbar herniation recur after laminectomy? Intervertebral foraminoscopy only removes the herniated discs, but 90% to 95% of the normal discs are still in the original position, so there is still a risk of recurrence. The recurrence rate of foraminoscopic surgery is basically the same as that of traditional open surgery, which is generally about 5%. If patients pay more attention after surgery, try to avoid bending and heavy lifting, avoid sitting, wearing high heels and doing strenuous exercise, the probability of recurrence can still be reduced. Secondly, if the recurrence is still needed for the second surgery? If the pain or numbness is only mild and can be improved with certain conservative treatment, there is no need for secondary surgery; if the pain is severe or lasts for a long time, and the symptoms cannot be completely relieved even after conservative treatment, you can still choose to have secondary surgery. As mentioned earlier, the chance of recurrence is about 5%, and the probability of secondary surgery is even lower than this chance. So can a second surgery still be minimally invasive? This is determined by the size of the patient’s scar after the first surgery, the location of the disc re-protrusion, and the size of the protrusion, which requires a systematic evaluation by a specialist. Do I need to take medication or other adjuvant therapy after the foraminoplasty? After surgery, the doctor will generally recommend that the patient wear a lumbar brace for about one month to play a role in stabilizing the lumbar spine. In the early postoperative period, you can take some anti-inflammatory and pain-relieving drugs and muscle relaxing drugs to relieve the pain in the lower back, and you can also use some nerve-nourishing drugs to relieve the numbness in the lower limbs. Fourth, how long can I go to work after surgery? How long can I go to work after surgery is determined by the patient’s recovery. Some patients go back to work half a month after surgery, while others need to rest for one to two months. From the doctor’s point of view, the longer the patient rests, the better the recovery will be, and the chances of protruding again in the future will be lower. Most people can gradually return to the intensity of their daily activities after 4-6 weeks of rest. V. How long can I exercise after surgery? One month after surgery, patients can do some back muscle exercises, such as swallow flying, swimming, etc. After complete recovery, patients can even do sports like jogging, but it is recommended not to do such strenuous confrontation sports as playing basketball. 6. Is the cost of minimally invasive surgery higher than traditional surgery? Because foraminoscopic surgery uses local anesthesia and no internal fixation devices are used during the surgery, the cost may be lower than that of traditional surgery.
