Biomedical Analyses, Tolerance, and Mitigation of Acute and Chronic Trauma
Abstract
The objective of this multidisciplinary effort is to comprehensively investigate and develop objective tools to evaluate and mitigate injuries to military personnel from different types of primary mechanical loading and secondary trauma due to the initial insult. Loading situations may include external force applications simulating blast, vehicle impact, and single- and multi-cycle longitudinal load applications to the human body. The research is in progress. Literature reviews have provided specific directions for future experimental design. Tests conducted on the Hybrid-III ATD with both curved and straightened lumbar spines demonstrated that forces further away from the source of impact were less sensitive to changes in impact pulse configuration. An in vivo animal study is under way to compare two different artificial disc surgical interventions against the current standard of care, bony fusion. PMHS studies were done to assess lumbar spine fracture under vertical seat-pan loading. Studies indicated that acceleration pulse is a critical determinant of what body region fractures. Softer seats that generate a sigmoid pulse to the pelvis may protect the pelvis but contribute to lumbar spine fracture risk. Seat pan force magnitude may not be a good indicator of pelvis fracture.
