ارزیابی بیومکانیکی پیچ و پلاک ارتوپدی

Reliable Biomechanical Finite Element Analysis (FEA)

Stage 1: Design the Biomechanical FE Setup (Bone-Implant Fixation and associated Jigs)

Stage 2: Create the FE Simulation Setup in HyperMesh Software (with effective contact conditions between the components and effective meshing of the models)

Stage 3: Optimize the Loading & Boundary Conditions and non-Linear Geometric Analysis Parameters to obtain the Reliable Results

Stage 4: Optimize the Design Parameters of the Implant

Enhanced Biomechanical FEA Characters

Using of Non-Linear Implicit Geometric Analysis for effective and reliable simulation of the deformation of the bone-implant construct under applied loading conditions, which would be greatly better than normal linear and explicit types of analyses. a

Meshing of the implant and bone with Fine Mesh (less than 500 mm mesh size) to maintain the irregularity and complexity of the geometry for obtaining the more reliable and accurate results. a

Effective defining of the contact conditions between the components for enhanced simulation of the load transferring. a

Using of RBE3-Bar element technique (innovative technique based on my long-term experience) for modeling and simulation of the screws, particularly locking screws. a

Avoid direct applying of the load to the components and using of adequate jig or tool to apply the load as similar to the conditions that would be utilized in experimental test. a

Similar or Close trend of the Force-Displacement Graph, between the enhanced FE simulation analysis and experimental test by consideration of real conditions in experimental testing. a
