Change and the clinical implication of nitric oxide and superoxide dismutase in degenerative lumbar intervertebral disc tissue;

A distribution and quantitative study on elastin in normal and protruding lumbar intervertebral disc;

Objective To observe angiogenesis and the expression of vascular endothelial growth factor and basic fibroblast growth factor and discuss its significance in normal and degenerated lumbar intervertebral discs.

Analyses of intra-stress and displacement of degenerate lumbar disc during simulating rotatory manipulation by finite element;

Early surgery for cauda equina syndrome secondary to lumbar disc herniation;

Clinical application of nucleoplasty in management of the lumbar disc herniation;

Diagnosis and treatment of pratrousion of the upper lumbar intervertebral disc;

The effect of disc height and degeneration on the mechanical behavior of lumbar spine:A finite element analysis;

Methods A series of new effective computer aided design(CAD) methods such as modified "no-seed region segmentation" and non-parallel "best cross-section planes" were used to accurately establish finite element(FE) models of the lumbar L4～L5 segment,representing the variation of disc height,facet-joint angle and lordosis angle of .

ObjectiveTo study the function of axially-loaded MSCT scanning, and analyse the value of this method in the diagnostic of slipped lumbar intervertebarl disc using a compression device, by comparing lumbar spine disc height and intervertebral angle of spine healthy volunteers.
