The increasingly fast pace of life, more and more diverse recreational facilities, they enrich the modern life, but also make everyone wrong posture appears more and more frequently! A herniated lumbar disc can lead to paralysis? And how can we prevent it? Why is there pain and numbness in the lower limbs? The herniated disc compresses and stimulates the nearby sciatic nerve root, and the patient feels pain on one side of the lower back, radiating all the way to the calf and foot via the buttocks and the back of the thigh, and accompanied by numbness in the calf or foot. In severe cases, claudication occurs, and the symptoms worsen when coughing or straining to defecate. This symptom is then called sciatica. The nerve root pain is mainly caused by the stimulation of chemicals released by the rupture of the fibrous ring, and the numbness is caused by the physical compression of the nerve root, and the pain is usually predominant when both are present. When both are present, the pain is usually predominant. When the inflammation has largely disappeared or is not obvious, the numbness is predominant. Can it cause urinary and fecal incontinence? Incontinence can occur in some patients who have been suffering from lumbar disc herniation for a long time and have been improperly treated! This is because the herniated disc is lumbar 4~5 or lumbar 5~sacral 1, and the herniated disc is large and central, which severely compresses the cauda equina nerve, causing numbness in the perineum in the early morning, followed by loss of control of urination and defecation. Such patients are often accompanied by paralysis of the lower limbs to varying degrees. But there is no need to panic! Most of the clinical treatment for herniated discs is now more effective, and few patients develop incontinence to the extent that they are incontinent. If they do, they tend to develop suddenly, in which case they should be treated immediately with surgery to avoid irreversible damage caused by prolonged compression. Can it lead to paralysis? A herniated disc compressing a nerve root can lead to nerve paralysis and muscle paralysis if the compression worsens. This condition is mostly seen in lumbar 4~5 disc herniation and paralysis of the anterior tibialis, long and short peroneal muscles, extensor digitorum longus and extensor digitorum longus muscles due to lumbar 5 nerve palsy, which mainly manifests as foot drop, weakened muscle strength, partial paralysis of the ankle joint and toes may occur, and complete paralysis of the lower limbs rarely occurs. Why are the lumbar 4 and 5 discs always injured? Lumbar disc herniation can occur in any of the lumbar intervertebral discs, but the lumbar 4 to 5 intervertebral discs are the most common, which is mainly determined by the anatomical structure and biomechanical characteristics of the lumbar spine. Anatomically, the width of the posterior collateral ligament of the lumbar segment decreases from top to bottom, and in the lumbar 4-5 and lumbar 5-sacral 1 segments the width is only half of the upper part. These two lumbar vertebrae bear 60% of the body weight and have the greatest mobility, so they are most prone to strain and degeneration, and are also the parts with the greatest incidence of developmental variation, and have the greatest potential for disc herniation. How to prevent lumbar disc herniation? 1, regular health examination, if found crest congenital deformity, or sudden deformity, promptly go to the hospital for examination, in labor should pay attention to protect the waist, to prevent repeated injury. 2.Improve labor posture and correct bad labor habits. The pressure on the lumbar intervertebral disc during bending activities is more than double that of normal standing, so the incidence of lumbar pain is higher in bending workers than in standing ones. 3, strengthen muscle exercise, strong lumbar back muscles can prevent lumbar soft tissue injury, abdominal muscle and intercostal muscle exercise can increase intra-abdominal pressure and intrathoracic pressure, help reduce the load on the lumbar spine. 4, such as low back pain disease patients should be early examination and treatment, exercise or rest under the guidance of a doctor, in order to facilitate early recovery.
