RISInvestigation of Vibration Characteristics of the Ligamentous Lumbar Spine Using the Finite Element Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A nonlinear, three-dimensional finite element model of the ligamentous L4-SI segment was developed to analyze the dynamic response of the spine in the absence of damping. The effects of the ...
Possible Role of Stresses in Inducing Spinal Stenosis—A Long Term Complication Following Disk Excision
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A three-dimensional finite element model of an intact ligamentous lumbar motion segment (L3-4) was used to predict stresses in the pars interarticularis regions of the modeled vertebral bodies. ...
Cancellous Bone Young’s Modulus Variation Within the Vertebral Body of a Ligamentous Lumbar Spine—Application of Bone Adaptive Remodeling Concepts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Bone remodeling theory based on strain energy density (SED) as the feedback control variable was used in conjunction with the finite element method to analyze the shape of the vertebral bodies ...
Application of the Finite Element Technique in the Design and Evaluation of the Artificial Facets for the Lumbar Spine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimentally validated three-dimensional (3D) finite element (FE) model of the ligamentous L3–S1 segment was used to study the effects of artificial facet designs on the segment biomechanics ...
