What is a lumbar intervertebral disc? The normal human spine consists of 26 vertebrae, with a soft cushion in the middle of the vertebrae called the intervertebral disc. The lumbar disc is the intervertebral disc in the lumbar spine. The intervertebral discs are tough and flexible, and can be compressed under heavy pressure and recovered after the pressure is removed, so that they can cushion the external shock to the spine. The thickness of the lumbar disc is the thickest and strongest of all intervertebral discs, and its shape is compatible with the physiological curvature of the human spine, and it is at the lowermost end of the spine, where the pressure is greatest and most concentrated, plus the mobility of the lumbar spine is greater, so lesions of the lumbar disc are very common. Lumbar disc herniation: A lumbar disc herniation is a clinical imaging manifestation with objective images of a herniated or bulging lumbar disc on imaging (CT, MRI, etc.). Usually, after a person reaches a certain age, the lumbar disc will be more or less herniated, especially in middle-aged and elderly people. Q1: Why is it easy to have a herniated lumbar disc when I get older? A1: Simply put, when a person gets older, it means that the lumbar discs are older and more worn and fragile, so it is not difficult to understand why they are prone to failure. Q2: Why is the proportion of herniated lumbar discs higher in men than in women? A2: Men are more manual laborers, and the wear and tear on the lumbar spine is more serious; men are more likely to have sports injuries because they are engaged in sports, which can cause lumbar disc herniation; long-term smoking is more likely to cause disc lesions, and men are more likely to smoke than women. Q3: Can I feel the lumbar disc herniation during the examination? A3: No, the lumbar disc is in the middle of the vertebral body, underneath the bones and muscles of the body, and cannot be felt. What is a lumbar disc herniation? Lumbar disc herniation ≠ lumbar disc herniation Lumbar disc herniation is a series of symptoms such as lumbar pain, numbness and pain in the lower limbs due to compression or stimulation of adjacent spinal nerve roots caused by lumbar disc herniation, which means that lumbar disc herniation = lumbar disc herniation + clinical symptoms Common clinical symptoms: lumbar pain, radiating pain in the lower limbs, numbness and weakness in the lower limbs, etc. In serious cases, perineal and perianal sensation may occur. abnormal sensation, loss of control of urination and defecation, and incomplete paralysis of both lower limbs, etc. Treatment of lumbar disc herniation: The vast majority of patients with lumbar disc herniation can have their symptoms relieved or even completely disappeared through conventional conservative treatment such as rest and recuperation, low back muscle exercise, physical therapy and traction, etc. Only a small number of patients with severe symptoms need surgery. Lumbar disc herniation precautions Whether it is lumbar disc herniation or lumbar disc herniation, attention should be paid to the protection of the lumbar spine in daily life: Avoiding actions: When suffering from lumbar disc herniation, usually pay attention to lumbar protection and try to avoid actions that can easily lead to increased pressure on the lumbar discs, it is recommended 1. less bending, especially bending with weight: such as bending to carry things, sit-ups, excessive bending yoga movements, etc.; 2. less Sit on a short stool, soft sofa, usually pay attention to sitting posture 3, try to avoid running, jumping and other strenuous exercise; 4, avoid squatting for a long time, use the toilet as far as possible to use the toilet Appropriate exercise: it is recommended that patients do appropriate exercises that can relieve the pressure on the lumbar disc, improve the mobility of the lumbar disc or strengthen the muscle strength of the low back, such as hanging bar, small swallow fly, freestyle swimming, etc.. But pay attention, if these items in the process of practice or after the exercise discomfort, pain aggravation, indicating that the project is not suitable for you to exercise, do not force yourself to try again.
