Lumbar Disc Herniation
Lumbar disc herniation is one of the most common diseases, mainly because all parts of the disc (nucleus pulposus, fibrous ring, and cartilage plate), especially the nucleus pulposus, have degenerative changes to varying degrees, under the influence of external forces. The rupture of the fibrous ring of the intervertebral disc, in which the nucleus pulposus protrudes (or protrudes) from the rupture to the rear or the spinal canal, resulting in stimulation or compression of adjacent spinal nerve roots, resulting in pain in the waist, numbness in one lower extremity or in both lower limbs. About 95% of lumbar disc herniation occur in the lumbar 4, lumbar 5-sacral 1.
1.Degenerative change of lumbar intervertebral disc (the basic factor)
Long-term repeated external force caused slight damage, aggravated the degree of degeneration.
3.The weakness of intervertebral disc
5.Lumbosacral congenital abnormality
