Human cadaver and Hybrid III responses to axial impacts of the femur.

This study examined the responses of 126 human cadaver and 222 Hybrid III dummy femurs undergoing dynamic axial impact. First, for human cadaver leg impacts, applied femur force alone was shown to do a good job of separating injury from non- injury. The combination of applied femur force and femur force rise time also was investigated. Second, 191 Hybrid III femur responses in vehicle collisions were explored.
