Evaluating the Anterior Stability Provided by the Glenohumeral Capsule: A Finite Element Approach

This biomechanical study uses subject-specific finite element models to identify standardized joint positions for clinical examinations of shoulder instability. The goal is to improve the accuracy of diagnosing capsular pathology, which has been linked to poor surgical outcomes.

GLENOHUMERAL CAPSULE SHOULD BE EVALUATED AS A SHEET OF FIBROUS TISSUE: A STUDY IN FUNCTIONAL ANATOMY

Susan Marie Moore

This paper presents a biomechanical and anatomical study of the glenohumeral capsule, revealing it as a continuous fibrous sheet rather than discrete ligaments. The findings show how regional fiber arrangements and tensile properties contribute to joint stability, guiding improved diagnostic and surgical strategies in shoulder biomechanics.

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.
