The effects of heavy physical activity has been controversial, as has a purported relationship to disk degeneration. Spondylosis occurs as a result of new bone formation in areas where the anular ligament is stressed. When back or sciatic pains are complaints, lumbar spondylosis is usually an unrelated finding. There usually are no findings unless a complication ensues. Growth of new bone projecting horizontally at these margins identifies osteophytes.
Most osteophytes are anterior or lateral in projection.
Posterior vertebral osteophytes are less common and only rarely impinge upon the spinal cord or nerve roots. Spine studies must assure that no osteophytes are in the area used for density assessment. This is because osteophytes produce the impression of increased bone mass, thus invalidating bone density tests if in the field of interest. Emergency department care Do not assume that patient's symptoms are related to osteophytosis. Look for an actual cause of a patient's symptoms.
