抄録

Skull fracture and cerebral contusion are caused by the translational acceleration on to the head. Cerebral concussion and DAI (diffuse axonal injury) are done by the rotational one. The sagittal rotational acceleration causes concussion and the coronal one does DAI. The pulse duration of the acceleration by which DAI can be caused is longer than the one for concussion. WSTC (Wayne State University Tolerance Curve) says that concussion can be caused by the translational acceleration rate of 90 G and over. According to some other studies, DAI tolerance limit is identified as follows: the rotational acceleration rate of 6,000-7,000 rad/sec^2, or 7,500 rad/sec^2. Few reports say that cerebral contusion may occur at the translational acceleration rate of 150 G, 180 G, 250 G, or 195-300 G (30,000-44,500 rad/sec^2). However, there may be no conclusive report about the level of the translational acceleration on to the head which can cause the cerebral contusion.
