Lumbar osteophytes and lumbar disc herniation belong to two diseases of different natures, with different definitions, pathophysiology and so on. 1. Lumbar osteophytes: a degenerative osteoarthropathy, commonly known as bone spur. Pathological changes are mainly bone cell hyperplasia resulting in osteoarthritis, structural abnormalities or deformities, thus causing pain due to pressure on the surrounding tissues of the lumbar spine. If the compression of the spinal nerve, can also cause some neurological symptoms. 2. Lumbar intervertebral disc herniation: It is a disease caused by the degeneration of lumbar intervertebral disc and the rupture of the annulus fibrosus, which leads to the herniation of the nucleus pulposus. The herniated disc can irritate or compress the nerves, resulting in a series of neurological symptoms such as radiating low back pain and numbness in the lower extremities. Although the symptoms may sometimes be similar, the treatments are different due to the different etiology and pathology of the two disorders.
