Intervertebral Disc Prostheses
Spine, 2003This article is based on a comprehensive review of the literature related to intervertebral disc prostheses.To compile an overview of the results and complications related to various types of lumbar and cervical disc replacements.A functional disc prosthesis has been sought since the 1950s. Although there were a few early attempts, disc replacement did

Intervertebral disc degeneration
Nature Reviews Disease PrimersIntervertebral disc (IVD) degeneration is a naturally occurring process that is a consequence of biological ageing and exposure to normal physiological loading over a lifetime and is characterized by loss of IVD tissue structural integrity. The nucleus pulposus changes with loss of pressurization, decreased collagen concentration and loss of ...

Intervertebral disc degeneration
European Spine Journal, 1993Disc degeneration in the human spine is a complex phenomenon characterised by biochemical change in the nucleus pulposus and inner annulus and the formation of clefts and fissures radiating from the central area of the disc towards the periphery. In addition, and probably independent of these phenomena, discrete defects in the outer annular attachement

Modeling of Intervertebral Discs
Spine, 1980A model with rotational symmetry of an intervertebral disc is studied. The nucleus pulposus is assumed to consist of an incompressible fluid, and the annulus fibrosus is modeled by 11 fiber layers with alternating fiber inclination. The spaces between the fiber layers are assumed to be filled with an incompressible fluid.

Intervertebral Disc Arthroplasty
Spine, 2004Review article of current knowledge of disc arthroplasty.To review the rationale for disc replacement, the general principles of design, and early clinical results.Disc arthroplasty is an emerging treatment for patients with disc degeneration. Its theoretical advantages are to maintain motion, decrease the incidence of adjacent segment degeneration ...

Estrogens and the intervertebral disc
Menopause International, 2009Intervertebral discs are an integral part of the vertebral column. It has been shown that menopause has a negative effect on bone and on intervertebral discs. Estrogen has a beneficial effect of preserving the health of collagen-containing tissues, including the intervertebral disc.

The British Journal of Radiology, 1948
The appearance of gas shadows in joints under certain conditions is well known. Young children whose laxity of the joint ligaments allows wide separation of the articular surfaces are especially prone to accumulate gas in the joint space when the joint is placed under strain.

Strategies for Regeneration of the Intervertebral Disc
Regenerative Medicine, 2008Low back pain resulting from degenerative disc disease is the most common cause of disability in the UK. Current low back pain treatments are aimed at either treating the symptoms of pain, or removing the source of pain itself, but do not address the biological basis of the disease.

The Innervation of the Cervical Intervertebral Discs
Spine, 1988Microdissection and histologic studies were undertaken to determine the innervation of the cervical intervertebral discs. The cervical sinuvertebral nerves were found to have an upward course in the vertebral canal, supplying the disc at their level of entry and the disc above.

Biochemistry of the Intervertebral Disc
Clinics in Sports Medicine, 1993In comparison to other tissues, understanding the disc biochemistry is only in the very early stage. The few facts that are known would point to strategies for interventions to alter disc biology and maintain disc biomechanics.
