Streszczenie:

'Background: Back pain is strongly (but variably) associated with degeneration of intervertebral discs. Mechanical loading has long been considered one of the causes of disc pathology and pain, but its precise role is poorly understood. In particular the spatial relation between load distribution inside the disc, the disc matrix changes as a result of load and their relationship with pain has not been researched. Methods: Distribution of compressive stress inside intervertebral discs from all regions of the spine was studied using stress profilometry in cadaveric motion segments. Matrix pathol

Streszczenie:

Degeneration and age affect the biomechanics of the intervertebral disc, by reducing its stiffness, flexibility and shock absorption capacities against daily movement and spinal load. The biomechanical characterization of intervertebral discs is achieved by conducting mechanical testing to vertebra-disc-vertebra segments and applying axial, shear, bend and torsion loads, statically or dynamically, with load magnitudes corresponding to the physiological range. However, traditional testing does not give a view of the load and deformation states of the disc components: nucleus pulposus, annulus f

Chronic lower back pain is a major public health problem, with direct and indirect economic costs comparable to those of heart disease, depression and diabetes. In many cases this pain derives from degeneration of the intervertebral disc (IVD), a fibrous, avascular tissue that sits between the vertebrae in the spinal column. A novel treatment approach for this ‘discogenic’ pain is the injection of a hydrogel that hybridises in situ and restores the normal biomechanical function of the disc. While a number of promising materials are currently under development, existing approaches to removing d

Degeneration of the lumbar disc, which frequently leads to low back pain, is an age related disease that often diminishes a patient's quality of life. Despite the continued efforts of research in this area, biological understanding of the disease remains unclear. The treatment strategies are few, with the gold standard being fusion of the motion segment, which permanently prevents any motion at the treated level of the spine. Although there are several new treatments available that attempt to recover some mechanical function of the motion segment, such as arthroplasty, they all remain unsatisf

Abstract Low back pain (LBP) is the leading cause of years lived with disabilities worldwide. Intervertebral disc (IVD) degeneration is a strong contributing factor to LBP. Recent studies have shown that genetic determinants contribute markedly to IVD degeneration but knowledge about the actual genes involved as well as their roles is still limited. The aim of this thesis work was to study genetic factors that may predispose to IVD degeneration. Using both family and case-control association study designs, variants in five genes showed association with IVD degeneration on magnetic resonance im

Low back pain is a major social and economic dilemma in the United States. Despite its high impact, the origins of low back remain unclear. Nonetheless, degenerative changes to the intervertebral discs (IVD) of the spine have been implicated as a possible source leading to pain. Poor nutritional supply to the IVD is believed to play a primary role in the pathophysiology of disc degeneration. Since the disc is avascular, vital nutrients, such as glucose, must be supplied by surrounding blood vessels. However, the transport and metabolic properties of glucose in the IVD have not been full

This thesis describes the development of artificial disc technology for the replacement of intervertebral discs in the human lumbar spine. The clinical problem is back pain. There may be a relationship between certain forms of back pain and disc degeneration. The mechanical properties of human intervertebral discs are examined in detail. The genetic basis of disc degeneration is presented. The hypothesis is that such degeneration leads to a loss of normal stiffness in the segments affected leading to abnormal mechanical behaviour which in turn leads to pain. The evidence for this is presented.
