Morphometry of the Intervertebral Disc Anulus Fibrosus by Diffusion Tensor Microscopy and Histology
The fibrocartilagenous anulus fibrosus (AF) is an integral structural and functional component of the intervertebral disc (IVD). A precise knowledge of its lamellar architecture (e.g., number of distinctive lamellae, thickness and collagen fiber orientation) is essential in developing morphologically accurate biomechanical models of the AF; however, available histology or x-ray diffraction-base...
متن کاملQuantification of Extracellular Matrix Proteins in the Nucleus Pulposus and Anulus Fibrosus of the Human Intervertebral Disc: Variation with Aging
*Singh, K; *Masuda, K; *Thonar, E.; *An, H; +*Cs-Szabo, G +* Rush University Medical Center, Chicago, IL [email protected] INTRODUCTION: The functions of the intervertebral disc (IVD) as a unit, and of the annulus fibrosus (AF) and nucleus pulposus (NP) individually, are determined by the molecular composition of their extracellular matrices (ECM). The outerand inner-AF consists of large collag...

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 "fibroca...

conclusion adc, fa, and t2* values may quantitatively reflect the microstructural characteristics of np, therefore they could be used to detect the minimal changes of early ldd. results the adc, fa, and t2* values were different (p < 0.05) among different rois within the same disc or among corresponding rois in different level discs. while the average values of adc increased regularly with the ...
متن کاملCollagen fibrillogenesis in the development of the annulus fibrosus of the intervertebral disc.
The annulus fibrosus of the intervertebral disc is a complex, radial-ply connective tissue consisting of concentric lamellae of oriented collagen. Whilst much is known of the structure of the mature annulus, less is known of how its complex collagenous architecture becomes established; an understanding of which could inform future repair/regenerative strategies. Here, using a rat disc developme...
