Evolution of Vertebroplasty: A Biomechanical Perspective

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.

Biomechanics of the Inferior Glenohumeral Ligament of the Shoulder

William Joseph Newman

This paper uses a subject-specific finite element model to analyze the biomechanics of the inferior glenohumeral ligament (IGHL) during a simulated simple translation test. It predicts regional strain and stress distributions, finding highly inhomogeneous strains that suggest a transfer of load between insertion sites with increasing external rotation. The study underscores the importance of computational biomechanics in understanding and diagnosing shoulder instability.

Strain Transfer between a CPC Coated Strain Gauge and Cortical Bone during Bending

This study uses the finite element method to simulate and analyze the transfer of strain between cortical bone and a calcium phosphate ceramic (CPC) coated strain gauge. The research explores how factors like interface thickness, debonding, and waterproofing affect strain measurement, providing recommendations for optimizing experimental setups. The findings have implications for the study of bone remodeling and other biomechanical research.
