A fall scenario is often given to explain the reason for a head injury to an infant. Mostly the examining doctor or forensic expert has to rely on his own experience and to appraise the situation to be consistent or not with his finds. An experiment carried out on an anatomical preparation showed that the skull of a newborn baby was able to repeatedly resist forces of up to 1000 N before breaking in. Even then the fracture lines followed the bony spikes (spiculae) from the ossification centers of the skull bones. If fractures are running across these spiculae there is reason to believe that high local force has been used, and a blow against a sharp edge must be considered.
人们常常给出一个摔倒的情景来解释婴儿头部受伤的原因。大多数情况下,主诊医生或法医专家不得不依靠自己的经验,并评估该情景与他的发现是否相符。在一个解剖标本上进行的一项实验表明,新生婴儿的头骨在破裂之前能够反复承受高达1000牛的力。即便如此,骨折线仍沿着颅骨骨化中心的骨棘(骨小梁)分布。如果骨折线横穿这些骨棘,就有理由相信使用了高局部力,并且必须考虑是受到了锐器边缘的打击。
