چکیده
main reasons for workforce losses. Disc herniation is important as it both causes symptoms and requires prolonged treatment. Intervertebral discs are 23 formations existing between adjacent surfaces of the vertebral bodies from the axis to the sacrum.1 The area surrounding the nucleus pulposus consists of fibers, which include a number of chondrocytes. Therefore, the tissue is known as "fibrocartilage". Disc herniation is a tearing of the anulus fibrosus (AF) as a result of a trauma, and degenerative changes, and a herniated nucleus often causes neurological symptoms, pressing a nerve root in the intervertebral foramen or vertebral canal.2,3 Macroscopic and microscopic structures of H

The effect of serial monolayer passaging on the collagen expression profile of outer and inner anulus fibrosus cells.
STUDY DESIGN Sheep outer and inner anulus fibrosus cells were isolated and analyzed to determine the effect of serial monolayer passaging on their phenotype. OBJECTIVES To characterize the effect of sequential serial passage on outer and inner anulus cells to determine at which point passaged cells are significantly different from freshly isolated cells. SUMMARY OF BACKGROUND DATA Previous ...
متن کاملThe ligaments and annulus fibrosus of human adult cervical intervertebral discs.
STUDY DESIGN Descriptive, microdissection study. OBJECTIVE To determine the morphology of the human adult cervical intervertebral disc and its ligaments. SUMMARY OF BACKGROUND DATA Some studies indicate that the cervical disc is distinctly different from the lumbar intervertebral disc, yet most clinical and anatomic texts appear content with extrapolating data from the lumbar spine. A detai...
متن کاملTears of the anulus fibrosus: correlation between MR and pathologic findings in cadavers.
Tears of the anulus fibrosus, which have been implicated in back pain, have not been studied systematically with MR imaging. We correlated MR images with cryomicrotome sections to study the lumbar anulus fibrosus in 20 cadavers. Three distinct types of tears of the anulus were identified: concentric tears, characterized by fluid-filled spaces between adjacent lamellae; radial tears, characteriz...
متن کاملEffects of cyclic mechanical stress on the production of inflammatory agents by nucleus pulposus and anulus fibrosus derived cells in vitro.
STUDY DESIGN Cyclic mechanical stress (CMS) was applied to cultured nucleus pulposus and anulus fibrosus cells, and the production of inflammatory agents by these cells was evaluated. OBJECTIVE To investigate the involvement of CMS in the production of inflammatory agents by disc cells. SUMMARY OF BACKGROUND DATA It has been reported that CMS affects degeneration of the disc. However, littl...
متن کاملAnalysis of Selected Mechanical Properties of Intervertebral Disc Annulus Fibrosus in Macro and Microscopic Scale
The main goal of this paper is experimental analysis of selected mechanical properties of single annulus fibrosus lamellae at macroscopic and microscopic levels as well as representation and explanation of the structural response to forced deformation. The conducted analysis of single annulus fibrosus lamella with preserved natural attachments revealed two characteristic mechanisms leading to d...
