Overview of lumbar disc herniation

Lumbar disc herniation is a common spinal disease, mainly caused by the rupture of the annulus fibrosus of the intervertebral disc and the herniation of the nucleus pulposus that compresses the nerve roots or spinal cord. Typical symptoms include low back pain, radiating pain in the lower limbs, numbness or weakness, which may affect walking in severe cases. The cause is related to long-term strain, poor posture, trauma or degeneration. Treatment methods include conservative treatment (such as physical therapy, drugs) and surgical treatment, which need to be selected according to the severity of the condition. Preventive measures emphasize maintaining correct posture, strengthening the lower back muscles and avoiding heavy physical labor.

Cause and pathogenesis

The direct cause of lumbar disc herniation is disc degeneration or external force injury. As we age, the moisture and elasticity of the intervertebral disc decrease, and the annulus fibrosus becomes fragile and easily broken; long-term bending, sitting for a long time, or sudden weight bearing will accelerate this process. In addition, trauma (such as falls, impacts) may also cause the annulus fibrosus to rupture and the nucleus pulposus to herniate and compress the nerves. Research shows that genetic factors, obesity and smoking also increase the risk. For example, smoking reduces the blood supply to the intervertebral discs and accelerates degeneration.

Typical symptoms and diagnosis

Patients often present with severe pain in the waist, which radiates to the lower limbs (such as buttocks, back of thighs to calves), and is aggravated when coughing or sitting for a long time. Some people experience numbness, weakened muscles, and even bowel and bladder dysfunction. Doctor passedPhysical examination(such as straight leg raising test) and imaging examination (MRI or CT) to confirm the diagnosis. It is necessary to pay attention to the identification of diseases such as lumbar spinal stenosis and piriformis syndrome to avoid misdiagnosis.

Treatment and Rehabilitation

Most patients can be relieved by conservative treatment, such as bed rest, nonsteroidal anti-inflammatory drugs (such as ibuprofen), physical therapy (traction, acupuncture), etc. In the acute stage, strenuous activities need to be avoided, and in the chronic stage, it is recommended to strengthen core muscle training. If conservative treatment is ineffective or severe nerve compression occurs, surgery (such as discectomy, minimally invasive transforaminal surgery) is required. Postoperative rehabilitation needs to be combined with progressive exercise to prevent recurrence.

Prevention and life advice

To prevent lumbar disc herniation, you need to start with lifestyle habits: maintain a correct sitting posture (avoid arching your back), control your weight, quit smoking, and regularly perform low-impact exercises such as swimming and plank support. When carrying heavy objects, bend your knees and squat instead of bending over. If you are already sick, you need to follow your doctor's advice for regular check-ups and avoid sitting or standing for long periods of time. Studies have shown that patients who adhere to rehabilitation exercises have significantly lower relapse rates.
