Many researches point out that intervertebral pressure and transformation are key parameters for evaluating intervertebral disc degeneration. Aiming at avoiding the damage caused by direct and indirect measuring methods, this research proposes a cylindroid hypothesis and measuring method, which can monitor the strain condition of the intervertebral disc in vivo and real-time without being damaged.

Title of Document: MINIATURE FIBER OPTIC PRESSURE SENSORS FOR INTERVERTEBRAL DISC PRESSURE MEASUREMENTS IN RODENTS Silas Nesson, M.S., 2007 Directed By: Assistant Professor Miao Yu, Department of Mechanical Engineering Mechanical stress due to interstitial fluid pressures can play a major role in the development of disc degeneration, a common cause of lower back pain. Pressures generated in the...

background & aim: low back pain is the most debilitating condition, and can lead to decreased physical function, compromised quality of life, and psychological distress. several studies have been conducted to recognize the risk factors of low back pain, but despite of strong relationship between obesity and low back pain, the underlying mechanisms are unclear. the aim of this study was to evalu...

conclusions in this study, we found that in spite of previous beliefs, discopathies were not common etiologies of lbp. thus, even in patients with proven ldh by imaging studies, the physician should perform a thorough evaluation for other causes of lbp to avoid unnecessary lumbar surgeries. results in our study, among 1250 patients with proven ldh by mri, 500 patients (40%) had chronic lbp and ...

STUDY DESIGN Biomechanical study. OBJECTIVE To evaluate the cervical facet loading profile of an intervertebral cervical disc prosthesis incorporating a unique saddle-shaped articulation and to determine the effect of implantation of the prosthesis on both the loading curve and area distribution of facet loading, when compared with that of an intact specimen. SUMMARY OF BACKGROUND DATA This...

It is now about thirty years since Schmorl (1929) described structural changes in intervertebral discs and in intervertebral bodies observed at necropsy. Disc surgery during the last twenty-five years has shown that there is a high incidence of disc ruptures in patients with low back pain and sciatica, and there is a wide belief that low back pain originates in the discs. Although it can be wel...

Background & Aim: Low back pain is broadly documented as one of the most widespread pathologies in the advanced domain. Although the reasons of low back pain are uncountable, it has been meaningfully related to intervertebral disc degeneration. Present therapies for Intervertebral Disc (IVD) degeneration such as physical therapy and spinal fusion reduce symptoms' severity, but do not treat the ...

A significant biochemical change that takes place in intervertebral disc degeneration is the loss of proteoglycans in the nucleus pulposus. Proteoglycans attract fluid, which works to reduce mechanical stresses in the solid matrix of the nucleus and provide a hydrostatic pressure to the annulus fibrosus, whose fibrous nature accommodates this stress. Our goals are to develop an osmo-poroelastic...
