1, what is an intervertebral disc and what is a herniated disc intervertebral disc and what is a herniated disc? The intervertebral disc is the material between the two vertebrae of the crestal spine, and the intervertebral disc is composed of three parts: the cartilage plate of the vertebral body, the nucleus pulposus, and the fibrous ring. The nucleus pulposus is a semi-fluid substance, surrounded by fibers and surrounded by cartilage plates above and below, in which the nucleus pulposus is tightly wrapped, with no room for up and down movement, only back and forth movement, and because the vertebral body is low in the front and high in the back, the position of the nucleus pulposus is slightly to the rear, and the thickness of the entire lumbar disc is about 8 to 10 mm. Lumbar disc herniation is due to trauma, long-term strain, strain, uncoordinated force, improper posture and other reasons leading to degeneration of the disc tissue, rupture of the disc and protrusion of the nucleus pulposus from the breakage. 2, the causes of herniated discs The causes of herniated discs, herniated discs are commonly found in five factors, increased abdominal pressure, such as violent coughing, constipation when forceful defecation, etc. The second lumbar posture is improper, when the lumbar is in flexion, such as sudden rotation, it is easy to induce a herniated nucleus pulposus. Third, sudden weight-bearing, when not fully prepared, sudden increase in lumbar load, easy to cause herniated nucleus pulposus. Fourth, trauma to the lumbar region. Acute trauma can affect the cartilage plate and other structures of the fibrous ring, which can cause the herniated nucleus pulposus to degenerate. Five occupational factors, such as car drivers in a sitting position for a long time and long-term bumpy easily lead to the most keyboard protrusion 3, lumbar disc protrusion to do what examination good lumbar disc protrusion to do what examination good. Generally, if you have the conditions, it is recommended to do the MRI scan of the lumbar spine. This kind of examination is very clear for the soft tissue display, and has a very good effect on the diagnosis of lumbar disc herniation. The tissue is clearly displayed, especially for the water content of the disc and the inflammatory edema of the nerve tissue. You can also consider x-ray plain film and ct examination, but x-ray film is no way to clarify whether there is a lumbar disc herniation. The CT is very sensitive to the bony structure, but the soft tissue is not clear enough, so many lumbar disc herniations are missed. 4.Typing of herniated discs The typing of herniated discs. According to the morphology of the herniated nucleus pulposus can be divided into three types, augmentation type, the protrusion is more hemispherical augmentation, the surface is smooth. Second rupture type, the herniation is irregular, fragmented or cauliflower-like, and often adheres to the surrounding tissue. Three free type. The fibrous ring is often completely ruptured, and the herniated fragments protrude through the rupture, free under the posterior longitudinal ligament, and enter the spinal canal. Second, according to the direction and location of the herniated disc, there are five rows: anterior protrusion, posterior protrusion, lateral protrusion, peripheral protrusion, and intracanal protrusion, of which posterior protrusion is the most common. 5, symptoms and performance of herniated discs Symptoms and performance of herniated discs, a lumbar pain will appear conscious dull pain in the lower back, this pain will be aggravated when standing and alleviated when lying down, is generally tolerable. The lumbar region can be moved appropriately and walked slowly, or sudden spasmodic pain can occur, which is unbearable and requires bed rest to alleviate. The second leg appears numb, stomach cold appears neck wheals, numbness in the lower limbs can be accompanied by pain, a few patients can appear simple numbness, or they feel cold and chilly in the lower limbs, can also appear see. 6, herniated disc and herniated disc symptoms herniated disc and herniated disc in the lumbar spine. A herniated disc is a rupture of the intervertebral disc’s fibrous ring, and the nucleus pulposus tissue protrudes or comes out from the place of rupture in the posterior or spinal canal, which is a pathological change or imaging change that is almost indispensable to the human aging process. It is not a disease. Lumbar disc herniation is a clinical combination of a series of symptoms such as lumbar pain, numbness and pain in one or both lower extremities due to irritation or compression of the adjacent nerve roots caused by a herniated lumbar disc. 7. Does a herniated disc have to be operated Does a herniated disc in the lumbar spine fly to be treated surgically? For the lumbar disc herniation whether surgery treatment? First of all, we need to determine which state of lumbar disc degeneration is in through examination, especially MRI examination? If it is in the early and middle stage, conservative treatment can generally be considered. If the disease is in the late stage, or if the nerve root compression is very obvious and heavy, then surgery needs to be considered. In fact, only 10 to 20 percent of patients with a herniated disc eventually need to go to surgery. Most patients go through lifestyle. 8, how to prevent lumbar disc herniation How to prevent lumbar disc herniation! Maintain the correct posture of the lumbar region. (1) Choose a chair that is high and has a backrest when sitting, and a hard bed when lying down. (2) Within a certain period of time, the position should be adjusted at any time, do not be in a position for a long time, such as sedentary, especially a long time bending, most likely to cause lumbar disc protrusion. (3) Functional exercise can improve local blood circulation and reduce or eliminate edema of soft tissues around the lumbar intervertebral disc. (4) Pay attention to the warmth of the lumbar region to avoid suffering. 9, whether the lumbar disc herniation will recur after surgery whether the lumbar disc herniation will recur after surgery? Is there any recurrence after lumbar disc herniation surgery? It is related to the way of surgery. Of course, recurrence is only for a few people, but for most people there is no recurrence. A recurrence is usually a result of such surgery, which is a simple removal of the nucleus pulposus rather than a fixed fusion. If the procedure is performed with the removal of the nucleus pulposus and fixed fusion, there is no recurrence in this case. 10.Can a herniated disc be retracted by some means Can a herniated disc be retracted by some means? A herniated disc does not usually shrink on its own, and it is unlikely that it can be treated with any kind of object or medication. This has been conclusively proven in numerous clinical trials. Many patients often misunderstand that physical therapy can I retract during treatment or seeking medical attention, and in clinical practice press back, which is basically not the case and does not exist. But it is true that symptoms can be relieved by physical therapy or medication.
