Effects of Implant Design Parameters on Fluid Ingress During The Impingement/Subluxation

This biomechanics paper uses a computational fluid dynamics model to investigate how fluid motion during hip implant subluxation can draw wear debris into the bearing space. The study analyzes how factors like head size and position affect fluid velocity and particle transport, proposing that implant designs minimizing subluxation may help reduce wear and implant failure.

Research Report Trauma and Reconstructive Surgery

Prof. Dr. N. P. Haas

This is a research report from a Trauma and Reconstructive Surgery department, summarizing various biomechanics studies from 2001-2002. It covers topics ranging from cartilage and bone mechanics to fracture healing, THA implant performance, and spinal fusion devices, often employing experimental and computational methods to understand the role of mechanical factors in biological processes.

Anisotropic Constitutive Modeling and Noninvasive Wall Strength Estimation

Jonathan P. Vande Geest, PhD

This dissertation outlines a biomechanical approach to predicting abdominal aortic aneurysm rupture by developing and improving a rupture potential index. The author uses advanced techniques like anisotropic finite element modeling and a statistical model for noninvasive wall strength estimation to create a more accurate and patient-specific risk assessment tool.

Hexahedral Mesh Development of Free-Formed Geometry: The Human Femur Exemplified

This paper details the development of a standardized hexahedral finite element model of the human femur for biomechanical analysis. It provides a comprehensive guide on creating a high-fidelity mesh from CT data and validates the model by demonstrating that the highest predicted stresses align with common fracture locations.

Finite Element Analysis of Human Joints: Image Processing and Meshing Issues

P-L Bossart, H.E. Martz, K. Hollerbach

This paper details a semi-automated process for creating finite element models of human joints to study biomechanics. It describes the dataflow from acquiring high-resolution CT scans to generating specialized meshes, which are then used to simulate joint motion and analyze soft tissue stresses. This research aims to reduce the time and effort required to develop accurate, patient-specific models for clinical and orthopedic applications.
