Abstract Details

2014, Doctor of Philosophy, Ohio State University, Mechanical Engineering.
Head injuries to older motor vehicle crash occupants are of increasing importance because of the growing number of older occupants on the road and their elevated vulnerability to injury compared to younger occupants. Crash data analysis to understand head injuries of particular importance among aging crash victims identified subdural hematomas from bridging vein bleeding as particularly frequent and life-threatening for older occupants. Ultimately, in order to quantify the age-dependent relationship between whole head motion and risk of subdural hematoma from bridging vein bleeding, experimental test methods are needed to measure the potential for bridging vein stretch as a function of head kinematics. To that end, methods were developed to use high-frequency, high-speed, Brightness-mode (B-mode) ultrasound to image motion of the meninges and peripheral brain in head rotation tests using post mortem human subjects. Results of preliminary low-rate rotation tests using the developed methods suggest that motion relative to the skull resulted from deformation of the cortex, rather than from sliding of the meningeal layers. High-rate testing confirmed the potential effectiveness of the developed methods, which represent a first essential step in the definition of age-dependent estimates of the risk of subdural hematoma from bridging vein bleeding in motor vehicle crashes.
