Abstract: Lumbar intervertebrae disc protrusion is a term for the description of morphology, with different pathological changes, pathogenesis and clinical characteristics. We propose a new pathologoical classification including damage-herniation, degeneration-protrusion, posterior vertebral osteochondrosis with disc protrusion, and disc cyst. The appropriate treatment including surgical option should be selected according to pathological changes.

Key words: lumbar vertebrae, intervertebral disk displacement, pathology, surgical procedures, operative
