Stiffness of the endplate boundary layer and endplate surface topography are associated with brittleness of human whole vertebral bodies.
Stress magnitude and variability as estimated from large scale finite element (FE) analyses have been associated with compressive strength of human vertebral cancellous cores but these relationships have not been explored for whole vertebral bodies. In this study, the objectives were to investigate the relationship of FE-calculated stress distribution parameters with experimentally determined s...
متن کاملEndplate Topography is Associated with the Brittleness of Human Whole Vertebral Bodies
INTRODUCTION: Vertebral fractures are often the result of a progressive deformation process. Structural brittleness parameters should be considered relevant for such failure processes. Much of the previous work has been concerned with vertebral stiffness and strength but measures of brittleness such as work to fracture and failure displacement largely remained unexplored. In a previous study ex...
متن کاملIn vivo measurement of vertebral endplate surface area along the whole-spine.
Accurate determination of vertebral endplate surface area and diameters plays an important role in surgical procedures, spinal implant design and sizing. The objective of this study was to contribute with baseline information on the endplate geometrical parameters using subject-based 3D whole-spine computed tomography (CT) models based on myelogram CT images taken of 49 patients with spinal dis...
متن کاملRelationship of Schmorl's nodes to vertebral body endplate fractures and acute endplate disk extrusions.
BACKGROUND AND PURPOSE Literature regarding clinical pain syndromes associated with acute, traumatic Schmorl's nodes (SNs) is limited. Our purpose was to determine whether an SN could be related to a previous traumatic event producing either acute SN or a vertebral endplate fracture. METHODS Two neuroradiologists independently reviewed initial and follow-up MR examinations of 14 patients with...
متن کاملInjury to the vertebral endplate-disk complex associated with osteoporotic vertebral compression fractures.
BACKGROUND AND PURPOSE MR imaging has been used extensively for identification and determination of chronicity of VCF. A major emphasis is placed on identification of edema or fluid clefts within the vertebral body. Little attention is given to other spinal structures such as vertebral endplate, intervertebral disk, posterior elements, and facet joints, spinal ligaments, and paraspinal musculat...
