Low back pain is a clinical and public health problem affecting more than half of the population. Disc degeneration is a major source of low back pain. Long-term exposure to whole body vibration or sedentary work postures may have high association with disc degeneration. It is hypothesized that there is a preferential frequency for vibrational loading, which may increase the efficiency for flui...

Background: lumbar disc degeneration is a multifactorial degenerative disease which is affected by genetic inheritance and environmental factors. Type XI collagen is important for organization of the extracellular matrix and cartilage collagen construction. Rs1676486 is a SNP that causes the conversion of C-T, resulting in a change in the expression of the collagen 11 alpha chain. The T allele ...

background: a large proportion of patients presenting with lumbar disc disease are opium addicts in our region. it was, therefore, hypothesized that morphine might affect the intervertebral disc. we investigated the histological findings of morphine dependency on intervertebral discs in rat.   methods: forty nmri adult male rats (230-250 g) placed on ordinary diet and received aqueous solution ...

background: intervertebral disc herniation is a major cause of low back pain. several treatment methods are available for lumbar disc herniation including chemonucleolysis, open surgery, nucleoplasty, laser disc decompression, and intradiscal electrothermal therapy. the high prevalence of lumbar disc herniation necessitates a minimally invasive yet effective treatment method. in this study, we ...

conclusions the present data do not suggest that pregabalin is more efficacious than placebo in the treatment of lumbar and cervical radicular pain. however, the small sample size of this study may have affected the ability to detect such a difference. results data on 19 of the 39 patients recruited were available for analysis. no statistically significant differences in the pain, disability, a...

Background & Aims: Between 5% and 15% of patients with low back pain suffer from lumbar disc herniation, so intervertebral disc disease is one of the most common causes of low back pain. Surgical intervention for lumbar disc herniation is recommended in patients with severe symptoms and has hopeful results. Although surgery can reduce pain and improve physical function in the short term, its lo...

Intervertebral disc degeneration is a disease of the discs connecting adjoining vertebrae in which structural damage leads to loss of disc integrity. Degeneration of the disc can be a normal process of ageing, but can also be precipitated by other factors. Literature has made substantial progress in understanding the biological basis of intervertebral disc, which is reviewed here. Current medic...

Introduction: Disc degeneration is a natural aging process characterized by changes in appearance and chemical structure of the disc. This degeneration leads to back pain. In regard to the limitation of current therapeutical methods for patients with degenerated discs, arthroplasty has been suggested as an alternative method. To manufacture artificial discs for Iranians, determining normal lumb...

INTRODUCTION Varied definitions of disc pathology exist in the literature. Magnetic Resonance Imaging (MRI) classification systems incorporate several qualitative features including disc appearance, the distinction between the nucleus and the annulus, signal intensity and intervertebral disc height. The lack of a continuous measure has made it difficult to sensitively examine degenerative disc ...

introduction: due to limitations of current treatments for degenerative disc disease, arthroplastic methods to repair the diseased disc have been proposed. the artificial disc is a mobile implant for degenerative disc replacement that attempts to lessen the degeneration of the adjacent elements following interbody fusion procedures. because the success of artificial disc replacement depends on ...
