We investigated the mechanism of damage to the corpus callosum in a study of 46 brains obtained at the autopsies of patients with head injuries. After correlating the gross findings with the site of impact on the head, we think that such lesions in the corpus callosum are caused by stretching of callosal fibers and/or shearing forces in cases in which lateral movement or twisting of the brain occurs. This mechanism of the dynamic development of callosal injuries is also supported by the retraction bulb formation of axons found histologically in the corpus callosum.
我们在一项对46例头部受伤患者尸检获得的大脑进行的研究中，调查了胼胝体受损的机制。在将大体检查结果与头部撞击部位相关联后，我们认为，在发生大脑侧向移动或扭转的情况下，胼胝体中的此类病变是由胼胝体纤维的拉伸和/或剪切力所致。组织学上在胼胝体中发现的轴突回缩球形成也支持了胼胝体损伤动态发展的这一机制。
