BACKGROUND AND PURPOSE The present standard for staging intervertebral disk degeneration is a discrete scale, consisting usually of 5 stages. The purpose of this pilot study was to investigate the use of T2 measurements as a continuous measure of intervertebral disk degeneration. METHODS We obtained images in 5 volunteers with a 3D fast spin-echo sequence modified for the purpose of calculati...
The traditional method of establishing the stiffness matrix associated with an intervertebral joint is valid only for infinitesimal rotations, whereas the rotations featured in spinal motion are often finite. In the present paper, a new formulation of this stiffness matrix is presented, which is valid for finite rotations. This formulation uses Euler angles to parametrize the rotation, an assoc...
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 ...
STUDY DESIGN T2 mapping was used to quantify moisture content of the lumbar spinal disk nucleus pulposus (NP) and annulus fibrosus before and after exercise stress, and after rest, to evaluate the intervertebral disk function. OBJECTIVE To clarify water retention in intervertebral disks of the lumbar vertebrae by performing magnetic resonance imaging before and after exercise stress and quant...
