Abstract

Life of a child is different when they experience shaken baby syndrome (SBS). Severe SBS can lead to a subdural hemorrhage from ruptured bridging veins. There’s plenty of research in the past about the biological aspect of SBS, but there is a lack of research about mechanical forces affecting the child’s head. This study aims to measure the angular displacement between the brain and skull using a Crash Resistant Air Bag Interaction (CRABI) model simulated in Siemens NX. The CRABI head model consists of the skull, arachnoid mater, subarachnoid space, and a hemispherical brain. The trabeculae are modeled as springs and connect the arachnoid mater to the brain to represent a proper motion of the brain within the skull. A displacement is applied to the CRABI torso to represent the caretaker translation force. Results show angular displacement presented in graphs of each case and their distinct oscillations. The cusp shown in each graph represents the angular displacement of the baby’s brain in the anterior or posterior region. This preliminary research helped us understand the mechanical forces of SBS and the reaction of the baby’s head to rotational displacement. The next steps of this study are to determine the rupture of bridging veins.
