DEVELOPMENT OF BIOMECHANICAL INJURY PREDICTOR FOR TRAUMATIC BRAIN INJURY

Abstract

This research work provided insight into the biomechanics of brain injury via computational modeling approach. First part of this report focuses on performing reconstruction of car crash accidents reported utilizing two commercial software. The objective of the reconstruction exercise was to predict head kinematics of the crash victims during the crash scenarios. The second part deals with employing a finite element model of the human head to study in details the ventricle system. Two clinically relevant issues were investigated with the model: peri-ventricular injury and ventricular enlargement. A preliminary injury risk curve based on ventricle enlargement is presented. The simulation studies improved our understanding in brain injury biomechanics and provided some new information in relation to ventricles dilation in traumatic brain injury victims. Ventricular enlargement after brain injury was found to place the victim at disadvantage where he/she is going to response in a more severe manner in subsequent injury
