What are the symptoms of lumbar osteophyte formation? The main cause of lumbar osteophyte formation is related to degenerative lesions of articular cartilage, and lumbar osteophyte formation is a common bone overgrowth disease.
Most patients with lumbar osteophyte formation can be asymptomatic for a long time. Initially, they may experience soreness and stiffness in the lower back. These symptoms tend to improve slightly after some activity following rest but worsen with excessive movement. Cold or damp weather often exacerbates these symptoms. Often, minor twists, overwork, lifting heavy objects, or occasional unconscious uncoordinated movements of the waist can lead to acute episodes. During an acute episode, the pain in the waist intensifies, making it difficult to move or turn over. Sometimes, there is also radiating pain along the distribution of the nerve root, such as the common sciatica, muscle spasms, and localized tenderness. The tenderness is usually located beside the spinous process or has a wide range of tenderness, although in fewer cases, there may be no tenderness.
Lumbar osteophyte formation occurs because after middle age, with increasing age, the physiological functions of various tissues and cells in the body gradually decline and age. The degenerated intervertebral disc gradually loses water, the intervertebral space narrows, the fibrous ring relaxes and protrudes peripherally, the vertebral body becomes unstable, and the fibrous ring tears at the edge of the vertebral body. This leads to the protrusion of the nucleus pulposus, which lifts the periosteum of the posterior longitudinal ligament, producing new bone underneath, forming bone spurs or bone overgrowth.
At the same time, some people believe that after the intervertebral disc degenerates and shrinks, the vertebral body tilts forward, and the anterior edge of the vertebral body is blocked by the anterior longitudinal ligament on the midline, causing the periosteum on both sides to lift, leading to the formation of new bone under the periosteum. Additionally, local pressure factors are also the main causes of osteophyte formation, with the edges of the lumbar vertebrae being subjected to heavier pressure.
