What is the cause of lumbar protrusion

Many people confuse lumbar spondylosis and lumbar disc herniation, but in fact they are two completely different conditions. Lumbar disc herniation is mainly caused by deformation of the lumbar vertebrae in the human body, while lumbar bulge is caused by tearing due to damage to the fibers in the human lumbar vertebrae. However, there are many reasons for lumbar bulge. Next, I will introduce to you the specific causes of lumbar bulge.

The causes are as follows:

1. Degenerative changes of the lumbar intervertebral disc are the basic factors. The degeneration of the nucleus pulposus is mainly manifested by a decrease in water content, and may cause small-scale pathological changes such as vertebral instability and loosening due to water loss; the degeneration of the annulus fibrosus is mainly manifested by a decrease in toughness.

2. Damage. Long-term and repeated external forces cause minor damage and aggravate the degree of degeneration.

3. Weaknesses of the intervertebral disc’s own anatomical factors. After adulthood, the intervertebral discs gradually lack blood circulation and have poor repair ability. On the basis of the above factors, some inducing factors that may cause a sudden increase in the pressure on the intervertebral disc may cause the less elastic nucleus pulposus to pass through the annulus fibrosus that has become less tough, causing nucleus pulposus herniation.

4. Genetic factors. There are reports of familial incidence of lumbar disc herniation.

5. Congenital abnormalities of the lumbar sacral region. Including lumbar sacralization, sacral lumbarization, hemivertebra deformity, facet joint deformity and articular process asymmetry. The above factors can change the stress on the lower lumbar spine, resulting in increased intra-disc pressure and susceptibility to degeneration and injury. 6. Predisposing factors. On the basis of intervertebral disc degeneration, certain factors that can induce a sudden increase in intervertebral space pressure can cause nucleus pulposus herniation. Common inducing factors include increased abdominal pressure, incorrect waist posture, sudden weight bearing, pregnancy, cold and moisture.

treat:

1. Non-surgical treatment: absolute bed rest; traction therapy; physical therapy and manipulation; supportive treatment; epidural injection of corticosteroids; chemical nucleolysis, etc.

2. Percutaneous nucleotomy/laser vaporization of the nucleus pulposus;

3. Surgical treatment.
