Three-Dimensional Finite Element Modeling of Dilated Human Ascending Aorta

Ajay Bohra, Thoralf M. Sundt, and Ruth J. Okamoto

This study uses a patient-specific finite element model of a dilated ascending aorta to investigate the distribution of wall stresses. The research reveals that the complex 3D geometry of the aorta, not just its diameter, is a significant factor in determining the risk of rupture.

Bone Regeneration and Fracture Healing: Experience With Distraction Osteogenesis Model

This study uses distraction osteogenesis in a rabbit model to investigate how mechanical forces influence bone formation. The results show that bone regeneration is highly sensitive to changes in the strain environment, suggesting that physical forces play a crucial role in the healing process.

Evolution of Vertebroplasty: A Biomechanical Perspective

Kay Sun and Michael A. K. Liebschner

This paper provides biomechanical evidence from computational studies on vertebroplasty, suggesting its limited effectiveness in treating existing fractures. Instead, the authors propose its use as a prophylactic treatment to reinforce osteoporotic vertebrae at risk of fracture, using patient-specific finite element models to improve treatment.

3-D Finite Element Model Development for Biomechanics: A Software Demonstration

K. Hollerbach, A.M. Hollister, E. Ashby

This article describes a new computational approach to biomechanics using a three-dimensional finite element model. It details the process from data acquisition from medical scans to visualization of results, using examples of the human hand and knee to demonstrate the methods and software developed for this purpose. The goal is to move beyond the limitations of older 2D models to more accurately simulate complex, nonlinear biomechanical systems.

Finite Element Analysis of Human Joints

P.L. Bossart and Karin Hollerbach

This paper details a semi-automated method for creating finite element models (FEMs) of human joints from high-resolution CT scans. The process reduces development time by automating key steps, from data processing to generating detailed hexahedral meshes, for use in biomechanical analysis and clinical applications.
