We describe briefly and comment upon the salient strengths and limitations of the major published theories that purport to explain the mechanism of contrecoup cerebrocortical contusions. Through the application of mechanical principles, we then present a modification, clarification, and expansion of selected aspects of several theories. Our final formulation emphasizes the injurious potential of nonuniform compressive stress and the relationship between brain lag and rotationally induced injury. The resulting theory remains faithful to the laws of physics while explaining the location and distribution of cerebrocortical contusions opposite the site of a moving head impact.
我们简要描述并评论了主要已发表理论的显著优势和局限性，这些理论旨在解释对冲性脑皮质挫伤的机制。通过应用力学原理，我们随后对几种理论的选定方面进行了修正、澄清和扩展。我们最终的阐述强调了非均匀压缩应力的致伤潜力以及脑滞后与旋转性损伤之间的关系。由此产生的理论在解释移动头部撞击部位对侧脑皮质挫伤的位置和分布时，仍然符合物理定律。
