In order to explore the linkage between coronary stenosis and hemodynamics, numerical simulation was applied to a patient-specific coronary artery tree model with multiple stenoses and a virtually healthy artery model in this study. Coronary plaque was found to form more likely in locations with disturbed flow conditions characterized by low WSS and high RRT or high WSS and low RRT. In contrast to anatomic parameters, hemodynamic environment, such as blood flow rate, plays an important role in stenosis formation.

A finite element simulation on a fracture fixated clavicle was performed to study effects of different fracture fixation parameters on the callus region. Specifically, parameters such as plate material, thickness, plate/bone gap, screw length, and locking versus non-locking screws were explored. Plate thickness and locking versus non-locking screws were found to be influential to construct stiffness where plate/bone gap and number of screws were not as sensitive.

This paper presents a fluid–structure interaction model incorporating viscoelastic wall properties that can be derived from in vivo measurements. By applying the fluid–structure interaction model to an idealized carotid artery under pulsatile flow, we have demonstrated its capability of predicting the viscoelastic wall behavior. Because the model is not limited to simple geometry, it can be applied to anatomically realistic arterial models. It also allows variations of stress and displacements within the vessel wall to be resolved.
- Development and implementation of a coupled computational muscle force optimization bone shape adaptation modeling method
C. S. Florio
Article first published online: 18 FEB 2015 | DOI: 10.1002/cnm.2699
Gradient-based optimization methods to calculate individual muscle force magnitudes are directly coupled with gradientless optimization methods to predict bone strength adaptations to study multisegment musculoskeletal system behavior. Using this tool, bone shape alterations that decrease surface stress variations for a number of examined conditions are identified. Quantitative comparisons of muscle activity, the ensuing bone shape adaptations, and their effects throughout the system provide means for an improved understanding of their interrelationships and the development of effective targeted strengthening exercises.
