Computer Aided Modeling and Finite Element Analysis of Human Elbow

Abstract

Finite element modeling (FEM) plays a significant role in the design of various devices in the engineering field of automotive, aerospace, defense etc. In the recent past, FEM is assisting engineers and healthcare professional in analyzing and designing various medical devices with advanced functionality. Computer aided engineering can predict failure circumstances, which can be avoided for the health and well-being of people. In this research work, computer aided engineering analysis of human elbow is presented beginning with modeling of human elbow from medical image data, and predicting the stresses in elbow during carrying heavy loads. The analysis is performed by using finite element method. The results predict the stress level and displacement in the human bone during heavy weight lifting. Thus, it can be used to predict the safe load that a particular person can carry without bone injury. The present analysis focused on a particular model of bone for a particular individual. However, safe load can be determined for various age groups by generating more detailed model including tendons, ligaments and by using patient specific material properties.

Investigating Elbow Dislocation and Instability: A 3D Finite Element Analysis Approach

“…Reconstruction of the joints done using NMR images. In 29 , medical images were used to model a human elbow and study the stresses in the elbow during heavy weight lifting. Finite element analysis was used and was shown to allow the prediction of stress level and displacement in bones, and thus the safe load that can be carried without causing bone injuries.…”
