Towards A More Robust Lower Neck Compressive Injury Tolerance - An Approach Combining Multiple Test Methodologies, Daniel Toomey, King H. Yang, N Yoganadan, F A. Pintar, C A. Van Ee

Biomedical Engineering Faculty Research Publications

Objective.The compressive tolerance of the cervical spine has traditionally been reported in terms of axial force at failure. Previous studies suggest that axial compressive force at failure is particularly sensitive to the alignment of the cervical vertebra and the end conditions of the test methodology used. The present study was designed to develop a methodology to combine the data of previous experiments into a diverse dataset utilizing multiple test methods to allow for the evaluation of the robustness of current and proposed eccentricity based injury criteria.

Methods. Data was combined from two studies composed of dynamic experiments including whole …

Cervical Spine Tolerance And Response In Compressive Loading Modes Including Combined Compression And Lateral Bending, Daniel Toomey

Wayne State University Dissertations

Injuries in motor vehicle accidents continue to be a serious and costly societal problem. Automotive safety researchers have observed noticeable lateral bending of the anthropomorphic test device (ATD) neck prior to or in conjunction with head impact with the vehicle roof in rollover crash tests. Since there is scant data available about the effects of lateral bending on overall compressive tolerance of the human cervical spine, it is unknown if the presence of lateral bending is important to consider during impacts with the apex of the head. Compressive injury tolerance has historically been reported by identifying the axial force at …
