Lumbar disc lesion in a narrow sense is lumbago with leg pain due to severe disc degeneration and loss of function, and does not include disc herniation. The MRI findings and clinical symptoms of lumbar disc lesion in patients with history of thirty years illness were examined. The clinical symptoms of the lumbar disc lesion were mainly difficulty of postual change and gait.
MRI findings showed moderate and diffuse findings (Grade 2 and 3 of Gipson's classification). The difference between MRI findings and histology of intervertebral disc was slight.
