1.What is a herniated disc? Lumbar disc herniation is a disease in which the nucleus pulposus protrudes and compresses the nerve roots after the rupture of the annulus fibrosus, causing back and leg pain as the main manifestation. 2.What are the manifestations of herniated intervertebral disc? Most of the manifestations are lumbar pain, radiating pain or numbness in the lower limbs. Longer duration of the disease may result in limitation of lumbar activities and intermittent claudication, etc. 3.What are the advantages of minimally invasive surgery treatment? Minimally invasive surgery is a new treatment method developed in the medical field in recent years, representing a new direction of medicine. Compared with traditional surgery, minimally invasive surgery has significant advantages such as no incision, no pain, no bleeding, zero injury and fast recovery, which are increasingly welcomed by doctors and patients. The purpose of minimally invasive surgery is to eliminate the herniated nucleus pulposus of the lumbar disc to relieve the compression of the nerve, with an incision of less than one centimeter. The nucleus pulposus is ablated or removed to fundamentally remove the causative factors, thus achieving excellent results. 4.What do I need to pay attention to afterwards? You should sleep on a hard bed, pay attention to the lumbar area to keep warm and avoid getting cold. After the symptoms improve significantly, you can gradually carry out back muscle exercises and do light activities on the ground under the protection of lumbar girth, but you must be careful not to carry excessive weight so as not to affect the recurrence of lumbar protrusion symptoms. Avoid strenuous exercise, avoid overload weight-bearing exercise and pay more attention to rest.
