To establish three dimensional finite element model of the whole cervical spine and investigate biomechanical characteristic of the human cervical spine for application of clinical diagnosis and therapy. Method: A healthy adult female was subjected, three dimensional finite element model of the whole cervical spine was established using the method of 3D interpolation with CT. Result: The model included...
The objective of this study is to develop a detailed three-dimensional geometrically and biomechanically accurate finite element model of the human lower cervical spine (C4-C6), and applied to determination of movement of the mobile type artificial disc replacement Prodisc-C made by Synthes. 3D (FE) model of the multi-level cervical spine was consists of three vertebrae and two intervertebral discs...
In order to check validity of the porcine ligamentum flavum as a substitute of human tissue for evaluating the epidural needles, the thickness and the Young's modulus were measured, and a finite element analysis was carried out. Twenty-four specimens were stained by the Elastica-van Gieson method. The average value of the thickness was 1.2 mm. The tensile tester was employed for measuring the Young's...
Previous studies have not produced a comprehensive description of the nonlinear hyperelastic stress-strain behavior of the periodontal ligament (PDL) of impacted tooth. In the present study, a simulation was applied to get the stress distribution in the PDL of impacted tooth. Firstly, a novel finite element modeling method for the PDL of impacted tooth based on CT image and reverse engineering was...
The apparent correlation between bone density and susceptibility to fracture was evaluated using finite element modeling. Based on computed tomography data of an actual femur bone, a versatile virtual model was created and modified in order to simulate different bone geometries and densities. Under typical load conditions the highest strains were calculated for the inferior side of the femur shaft,...
Background: Treatment of malignant tumors of the pelvis, especially in the periacetabular region continues to present one of the most challenging problems in oncological and orthopedic surgery. Even now, hindquarter amputation is still the only choice for some patients, but hindquarter amputation can cause much trouble in sitting, standing and in fitting the exoprosthesis of patients after amputation,...
