The collagen of the intervertebral disc in adolescent idiopathic scoliosis.
A defect in the collagenous matrix of the intervertebral disc has been proposed as a contributory factor in the pathogenesis or progression, or both, ofthe scoliotic deformity. In an attempt to resolve these questions the collagen extractability and distribution across normal and scoliotic discs was investigated. The collagen content ofthe scoliotic nucleus pulposus was found to be higher than ...
متن کاملThe effect of radiographic vertebral body and intervertebral disc wedging on curve progression in idiopathic scoliosis
Methods Baseline and 30-year follow-up x-rays from 56 AIS patients were evaluated. Wedging measurements included apical vertebral body height ratios (VBHR), apical vertebral body angles (VBA) and apical intervertebral disc wedging angles (IVDA). Intraand inter-rater reliability was estimated using 2 readers and a subset of 20 curves. Multivariate regression estimated the contribution of wedging...
متن کاملMRI signal distribution within the intervertebral disc as a biomarker of adolescent idiopathic scoliosis and spondylolisthesis
BACKGROUND Early stages of scoliosis and spondylolisthesis entail changes in the intervertebral disc (IVD) structure and biochemistry. The current clinical use of MR T2-weighted images is limited to visual inspection. Our hypothesis is that the distribution of the MRI signal intensity within the IVD in T2-weighted images depends on the spinal pathology and on its severity. Therefore, this study...
متن کاملScoliosis: discs and vertebrae. Cobb angle: friend or foe?
Introduction Both vertebral and disc deformity contribute to scoliosis deformity, but the Cobb angle measures both, without distinguishing their relative magnitudes, which are approximately equal. (The disc deformity is greater in the lumbar region than in the thoracic.) Most attention has been given to the vertebral deformity, which apparently develops because of growth disturbance, and some s...
متن کاملCobb Angle Quantification for Scoliosis using Image Processing Techniques
Measurement of Cobb angle is the standard technique used for scoliosis assessment. The challenging task in computerized method lies in totally automating the method of curvature measurement from digital X-ray images. In this paper we presented a method which automatically measures the Cobb angle from radiographs after selection of the end vertebrae of the curve. The image processing methods use...
