Introduction – aim The response of the intervertebral disc to asymmetric forces may accelerate degeneration through changes in the matrix. At a macroscopic level the disc sustains structural changes which may play a role in the progression of a scoliotic curve. At a molecular level, disc degeneration is the outcome of the action of matrix metalloproteases (MMPs), members of a family of enzymes ...
A cadaveric study was performed to investigate the relationship between disc degeneration and morphological changes in the intervertebral foramen of cervical spine, including the effect on the nerve root. Seven fresh frozen human cadavers were dissected from C1 to T1, preserving the ligaments, capsules, intervertebral disc and the neural structures. The specimens were scanned with MRI and then ...
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...
STUDY DESIGN A new rabbit model was developed that produces disc degeneration through the application of controlled and quantified axial mechanical load. OBJECTIVES To characterize the changes associated with disc degeneration, and to evaluate the feasibility of local transfer of agents to the compressed discs to stimulate disc regeneration. SUMMARY OF BACKGROUND DATA Studies have shown tha...
Intervertebral disc (IVD) degeneration is frequent, appearing from the second decade of life and progressing with age. Conservative management often fails, and patients with IVD degeneration may need surgical intervention. Several treatment strategies have been proposed, although only surgical discectomy and arthrodesis have been proved to be predictably effective. Biological strategies aim to ...
STUDY DESIGN Prospective study of changes in intervertebral disc degeneration after injection of bupivacaine. PURPOSE To examine whether injection of bupivacaine into human intervertebral discs accelerates their degeneration. OVERVIEW OF LITERATURE Bupivacaine is commonly used for therapy and diagnosis of discogenic low back pain. However, several in vitro studies have reported toxic effect...
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 of...
Back pain related to intervertebral disc degeneration is the most common musculoskeletal problem, with a lifetime prevalence of 82%. The lack of effective treatment for this widespread problem is directly related to our limited understanding of disc development, maintenance and degeneration. The aim of this study was to determine the developmental origins of nucleus pulposus cells within the in...
As a significant determinant of low back pain, intervertebral disc degeneration (IDD) has attracted more and more attention of both investigators and physicians. Disc herniation, termed as intervertebral disc displacement, is amongst the most prevalent spinal diseases closely linked with IDD. Due to the same origins and similar pathophysiology, the ambiguity regarding the similarity and differe...
Disc degeneration is a multifactorial process that involves hypoxia, inflammation, neoinnervation, accelerated catabolism, and reduction in water and glycosaminoglycan content. Cannabidiol is the main non-psychotropic component of the Cannabis sativa with protective and anti-inflammatory properties. However, possible therapeutic effects of cannabidiol on intervertebral disc degeneration have no...
