Abstract. Lumbar Disc Herniation (LDH) is a syndrome in which lumbar disc degeneration, rupture of the annulus fibrosus, and herniation of the nucleus pulposus irritate and compress the nerve roots and cauda equina, resulting in the main manifestations of lumbar pain and/or lower extremity pain. There is evidence in various …

Intervertebral discs are fibrocartilaginous structures located between the bodies of adjacent vertebrae. They form a fibrocartilaginous joint between the vertebral bodies, linking them together. Collectively, the discs contribute up to one-third of the length of the vertebral column, forming an interpose between adjacent vertebrae from the axis …

Dynamic motion sharing of segments from L2 to S1 were calculated and analysed for interactions between levels. Eight asymptomatic controls were then matched to the 8 patients for age and sex and their motion sharing patterns compared. Share of intersegmental motion was found to be consistently highest at L2-L3 and L3-L4 and …

Author Summary Low back pain is a very common pathology in industrialized countries, often due to bad posture. It is also highly related to intervertebral disc aging. Aging of the disc is a normal process characterized by series of changes in its structure and function. The events that convert normal aging into degenerative disease is …

Twenty-four intervertebral discs from six 4-month-old bovine lumbar spines were included in the study. Gross inspection of the bovine intervertebral discs confirmed the cross-sectional area proportions of the nucleus, inner annulus and outer annulus were similar to those of human intervertebral discs, while disc height was less than half that of …
