Biomechanics of the Inferior Glenohumeral Ligament of the Shoulder

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.

A Strain Map of the Human Distal Tibia During the Stance Phase of Walking

Researchers have developed a new method for mapping bone strain. They combined real-world data from a cadaver's tibia during simulated walking with a computational model. This approach created a 3D map of bone strain without making assumptions about how the bone was being loaded, providing valuable data for future biomechanical models.

Finite Element Modeling of the Inferior Glenohumeral Ligament Complex

This paper develops a finite element model to study the biomechanics of the shoulder’s inferior glenohumeral ligament. By simulating a cadaveric clinical exam, it quantifies force and strain distribution, highlights the ligament’s sensitivity to material properties, and provides a detailed view of its function as a load-bearing structure.

The Optic Nerve Head as a Biomechanical Structure: Initial Finite Element Modeling

A.J. Bellezza, R. T. Hart, and C. F. Burgoyne

This paper uses FEA, an engineering simulation technique, to model the optic nerve head as a complex biomechanical structure. By simulating how anatomical differences like scleral canal size and wall thickness affect internal forces, the study shows that physical stress on optic nerve tissues is substantial even at normal eye pressures. These findings are a critical first step in understanding how individual anatomy can create mechanical conditions contributing to glaucomatous damage.
