FRACTURE PROPAGATION PROPENSITY OF CERAMIC LINERS DURING IMPINGEMENT-SUBLUXATION

J. M. Elkins, D. R. Pedersen, J. J. Callaghan

This biomechanical analysis employs finite element modeling to assess the fracture propagation risk in ceramic hip liners during impingement and subluxation events. The study identifies specific surgical orientations and common movements such as squatting, stooping, and shoe-tying as critical biomechanical factors significantly increasing fracture vulnerability.

Upper Extremity in Response to Dynamic Impact Loading Indicative of a Forward Fall

Timothy Burkhart

This paper investigates the biomechanical response of the upper extremity during dynamic impacts from forward falls, using combined experimental and computational methods. It emphasizes the critical biomechanical factors influencing distal radius fractures, providing detailed fracture thresholds, kinematic insights, and validated computational models.

ASSESSMENT OF THE EFFECTS OF LIGAMENTOUS INJURY IN THE HUMAN CERVICAL SPINE

Patrick Devin Leahy

This dissertation integrates experimental testing and finite element modeling to investigate biomechanical changes caused by ligamentous injuries in the cervical spine. It identifies unique biomechanical responses associated with specific ligament injuries, providing valuable insights for improved clinical diagnosis and management of cervical spine trauma.

Abaqus/Standard-based quantification of human cardiac mechanical properties

Martin Genet, LikChuan Lee, Ellen Kuhl, Julius G.

This paper develops a computational biomechanics framework using Abaqus/Standard for personalized quantification of cardiac mechanical properties. Utilizing MRI data, the study optimizes passive and active myocardial parameters to accurately reflect individual-specific cardiac biomechanics, aiding improved diagnosis and treatment strategies for heart failure.

3D FE MODEL OF THE PATELLOFEMORAL JOINT CONTACT

S.-K. Han, S. Federico, W. Herzog, M. Epstein

The study develops a detailed 3D finite element model to analyze biomechanical changes in the patellofemoral joint due to small patellar misalignments, using a biphasic representation of cartilage. It demonstrates that minimal alignment deviations significantly alter contact pressures and equilibrium states, providing essential insights into potential degenerative joint mechanisms.
