Prediction of Traumatic Brain Injuries by FEM Through Accident Reconstructions

Abstract

In the head injury accidents, the injuries such as a bone fracture, bleeding or the cerebral contusion can easily be observed by the primary care and quick treatment is possible, but the nerve axonal damage is hard to be discovered and treatment tends to be late. In this paper, the method that predicts the detailed traumatic brain injury including the axonal injury by computer simulation based on emergency medical treatment data are presented and the items which are indispensable for the computer simulation in the medical data are shown. The medical data of 213 head injury accidents were provided by the hospital and they were classified into two groups, the group which can be reconstructed and the group which cannot be reconstructed. It was judged that 10 cases of the traffic accident of all 134 cases can be reconstructed and 23 cases of the fall/fall down accidents of all 61 cases can be reconstructed. As examples, the typical traffic accident and the fall down accident cases were introduced, and the reconstruction process of the accidents and the result of the brain injury prediction are explained in detail.
