A case of a boxer aged 26 years who was knocked out by a series of five punches and died in consequence after 3 days was reported. This boxing match was recorded incidentally by video recorder, so that we could consider the mechanisms of the head injury and reveal the correlation between the punches on the head and the brain damages, comparing the video-record with the autopsy findings. The post-mortem examination showed that there were a slight subdural hematoma on the convex surface of the right cerebral hemisphere and a marked cerebral contusion from both frontal bases to the inside of the right temporal lobe and from the left thalamus to the upper part of the mesencephalon. Characteristically, these contusions occupied the central and anterior part of the brain. From the localization of the contusion, it was supposed that these damages were caused by the hasty twist and strain of the brain and brainstem, when the head was quickly rotated around the cervical column in horizontal direction by the punches. The analysis of the series of five punches revealed that the last two punches made the head rotate quickly from left side to right around the cervical column in horizontal direction. These result of the analysis support the inference that this rotating movement of the head brought about the damage.
报道了一例26岁拳击手的病例，该拳击手被连续五拳击中后昏迷，三天后死亡。这场拳击比赛碰巧被录像机记录下来，这样我们就可以通过将录像与尸检结果进行比较，来研究头部损伤的机制，并揭示头部受拳与脑损伤之间的关联。尸检显示，右大脑半球凸面有轻微硬膜下血肿，从双侧额叶底部至右颞叶内侧以及从左丘脑至中脑上部有明显脑挫伤。这些挫伤的特征是位于脑的中央和前部。从挫伤的部位推测，这些损伤是由于拳击导致头部在水平方向绕颈椎快速旋转时，大脑和脑干发生急剧扭转和拉伸所致。对这连续五拳的分析表明，最后两拳使头部在水平方向绕颈椎从左侧快速向右侧旋转。分析结果支持了头部的这种旋转运动导致损伤的推断。
