Mechanical Conditions in the Internal Stabilization of Proximal Tibial Defects

This biomechanics paper presents a method for evaluating a new internal fixator for proximal tibial defects using in vitro testing and finite element analysis. The study found that under physiological loading, the implant experiences high stresses when stabilizing mid-shaft defects, indicating it is better suited for proximal defects.

Internal Stress/Strain State of the Foot Using Magnetic Resonance Imaging and FEA

Marc Thomas Petre

This paper integrates MRI-based anatomical modeling with finite element simulations to map the internal biomechanical environment of the foot. The findings reveal how different tissues respond to load, offering valuable insights for injury prevention, orthopedic treatment, and ergonomic footwear design.

A Computational Model of the Human Hand 93-ERI-053

K. Hollerbach and T. Axelrod

This biomechanics paper details the development of a computational model of the human hand using finite element analysis (FEA) to simulate joint motion in a physiologically realistic way by considering the geometry of articular surfaces and the deformation of soft tissues. It highlights the creation of new algorithms and material models that address the complex and nonlinear biomechanics of anatomical structures, which were previously not possible with traditional rigid body models.

Behavior on Intervertebral Disc L4-5 in Pedicle Screw System Instrumented Lumbar Spine

This biomechanics paper analyzes the compression behavior of the L4-5 intervertebral disc in a lumbar spine with a pedicle screw system using a finite element model under a follower load. The study focuses on how the instrumentation alters the segment's flexibility, nucleus pulposus pressure, and the stress distribution within the implant and disc.

Multidirectional Morphology and Mechanics of Osteonic Lamellae

Maria-Grazia Ascenzi and John M. Kabo

This patent describes a novel biomechanical model for human bone based on its hierarchical structure and mechanical properties. The model provides a way to predict bone deformation and fracture, offering a more realistic tool for applications like bone reconstruction and the design of prosthetics.
