    Regressive changes in lumbar intervertebral discs are common, even without symptoms. These changes, including necrosis and Schmorl

    Area of Science:

    • Spinal Anatomy and Pathology
    • Histopathology
    • Degenerative Disc Disease

    Context:

    • Histotopographic study of lumbar spines from 27 deceased individuals (ages 2-85).
    • Absence of pre-existing spinal clinical symptomatology in study subjects.
    • Focus on intervertebral disc changes and associated spinal pathologies.

    Purpose:

    • To investigate the prevalence and nature of regressive changes in lumbar intervertebral discs.
    • To explore the relationship between disc lesions and other spinal pathologies.
    • To examine age-related changes in disc glycosaminoglycans and nucleus pulposus.

    Summary:

    • Regressive changes, including central and pericentral necrosis, were observed in most intervertebral discs, except in infants.
    • Consequences of necrosis such as vascularization and scarring were noted, supporting the concept of disc lesions triggering further spinal issues.

  • Schmorl's nodes were frequent, even in young individuals without symptoms. Initial osteophytes were common at ventral vertebral margins.

    • Impact:

    • Provides histopathological evidence of early degenerative changes in the lumbar spine.
    • Highlights the potential for asymptomatic disc degeneration to initiate further spinal pathology.
    • Contributes to understanding age-related spinal changes and the development of conditions like Schmorl's nodes and osteophytes.
