Depressed skull fractures occur when broken bones displace inward, meaning that a portion of the outer table of the fracture line lies below the normal anatomical position of the inner table. They typically result from force trauma, when the skull is struck by an object with a moderately large amount of kinetic energy but a small surface area, or when an object with a large amount of kinetic energy impacts only a small area of the skull. In the present case, a depressed fracture of the frontal bone was detected at the autopsy of a 52-year-old man who, according to the belated confession of the assailant, was kicked in the head. The assailant was wearing sneakers. Could such a fracture be caused "just" by a kick? In this case it was possible due to an extraordinarily thin cranial vault (0.2 cm frontal, 0.3 cm occipital), which allowed the fractures to occur from a kinetic force that might not have been sufficient with a normal cranial vault thickness. An important role in the forensic analysis of the case was played by the 3D CT reconstruction.
凹陷性颅骨骨折发生在骨折的骨头向内移位时，这意味着骨折线的外板的一部分位于内板的正常解剖位置下方。它们通常是由外力创伤引起的，当颅骨被一个具有中等大量动能但小面积的物体撞击时，或者当一个具有大量动能的物体只撞击颅骨的一个小区域时。在本例中，在对一名 52 岁男子的尸检中发现了额骨凹陷性骨折，根据袭击者的事后供述，该男子的头部被踢了一脚。袭击者穿着运动鞋。这样的骨折仅仅是因为踢一脚就能造成的吗？在这种情况下，由于颅骨穹窿极薄（额骨 0.2cm，枕骨 0.3cm），使得骨折能够在可能不足以产生正常颅骨穹窿厚度的动能作用下发生。3D CT 重建在案件的法医分析中发挥了重要作用。
