STUDY DESIGN Retrospective review of imaging data from a clinical trial. OBJECTIVE To compare the interpretation of lumbar spine magnetic resonance imaging (MRIs) by clinical spine specialists and radiologists in patients with lumbar disc herniation. SUMMARY OF BACKGROUND DATA MRI is the imaging modality of choice for evaluation of the lumbar spine in patients with suspected lumbar disc her...

A twelve year old boy presented with acute cervical and interscapular pain, torticollis and low grade fever. The neurological examination was normal. Roentgenograms showed calcification of the T3-T4 disc and posterior herniation of the nucleus pulposus was demonstrated by computed tomography. A rapid and dramatic amelioration of the symptoms was produced by treatment with a non-steroidal anti-i...

OBJECTIVE Sciatic pain secondary to lumbar disc herniation is a complex condition that is often highly limiting. The causes of pain in disc herniation are multifactorial. Two physiopathological mechanisms are involved in discogenic pain: mechanical deformation of nerve roots and a biochemical inflammatory component resulting from contact between the intervertebral disc and neural tissue, by way...

Removal of herniated disc materials based on an imaging only method may not relieve symptoms in many patients. Therefore, the aim of the present study was to develop a transforaminal endoscopic method of classifying the pathological type of lumber intervertebral disc herniation and to compare the outcomes of surgery based on the pathological type with those of conventional endoscopic disc remov...

Objective: To investigate the clinical effect of Dynesys dynamic fixation for double-segmental lumbar disc herniation and the degeneration of adjacent segment. Methods: 52 patients, who received Dynesys dynamic fixation for double-segmental lumbar disc herniation in our hospital from Mar 2009 to Mar 2012, were enrolled as research subjects; among them, 34 were male and 18 were female with an av...

OBJECT Incidental durotomy is an infrequent but well-recognized complication during lumbar disc surgery. The effect of a durotomy on long-term outcomes is, however, controversial. The authors sought to examine whether the occurrence of durotomy during surgery impacts long-term clinical outcome. METHODS Spine Patient Outcomes Research Trial (SPORT) participants who had a confirmed diagnosis of...

We studied the natural history of extruded lumbar intervertebral discs using MRI. Forty-nine patients with lumbar disc herniation were included in this study. Ages ranged from 19 to 57. On the T2-weighted sagittal MR image, the signal intensity in the herniated mass was measured and the ratio to that in the original nucleus (i.e., nucleus pulposus from which they extruded) was calculated (signa...
