A biomechanical analysis of the clinical stability of the lumbar and lumbosacral spine.

چکیده
Eighteen Functional Spinal Units (FSU), representing three levels of human lumbar and lumbosacral spine, were tested using preload forces that corresponded to the clinical situation of a person lying supine or standing while subjected to maximum physiologic flexion or extension forces. Sagittal plane displacements were measured using linear variable differential transformers (LVDTs) and a MINC-11/03 minicomputer. Sequential transection of components in the posterior-to-anterior and anterior-to-posterior directions until failure occurred allowed measurements of the displacement sagittal plane translation and rotation of the intact and transected FSU.

This study aim to investigate the effect of different slops on mechanical lumbosacral angles and lumbar stability of healthy and mechanical low back pain (LBP) persons. This case- control study was performed on 38 females (18 LBP and 20 healthy subjects) who were referred to the Hospital in sari. At the beginning, Subjects’demographic data were recorded. In order to measure lumbosacral angles a...
متن کاملInflammatory Pseudotumor in the Epidural Space of the Lumbosacral Spine on F-18 FDG PET/CT
An inflammatory pseudotumor (IPT) is a rare benign lesion, characterized by nonneoplastic proliferation of inflammatory cells and presence of intermingling collagen fibers. IPT commonly occurs in the lungs and orbita, while an intraspinal IPT is extremely rare. IPT can mimic both clinically and radiologically malignant processes, and making a definitive preoperative diagnosis is often difficult...

Detailed investigation on biomechanics of a complex structure such as the human lumbar spine requires the use of advanced computer-based technique for both the geometrical reconstruction and the stress analysis. In the present study, the computer-assisted tomography (CAT) and finite element method (FEM) are merged to perform detailed three dimensional nonlinear analysis of the human ligamentous...
متن کاملبررسی رابطه کمردرد با زاویه لومبار لوردوز و لومبوساکرال
Background and purpose: Despite the high prevalence of mechanical low back pain, its etiology remains undiscovered in most of the cases. However, there have been many speculations about its origin based on X-ray findings and hyperlordosis of lumbar spine is an important factor. In this study, attempts were made to establish a possible relation between low back pain, lumbar lordosis and lumbosac...
متن کاملComparing the Effect of Alendronate and Vitamin D Administration on Lumbosacral Fusion and Severity of Low Back Pain in Patients After Posterior Lumbar Fusion Surgery: A Randomized Clinical Trial
Background and purpose: Bone fusion is a dynamic process and availability of calcium and balance of vitamin D can be effective in post spinal cord fusion. There are contradictory results on this issue, so, we decided to compare the effect of administration of vitamin D and alendronate on lumbosacral vertebral fusion in patients undergoing posterior spinal fusion surgery. Materials and methods:...
