Sharp-force injuries are injuries caused by a mechanical force using sharp objects against the skin. Sharp-force injuries are mainly classified as stab, incised, chop, and therapeutic wounds and are less frequent than blunt-force injuries in animals. The analysis of the edges of the wound is crucial, especially if more than one type of lesion is involved. It may be difficult to differentiate between sharp trauma and blunt trauma, because lacerations can resemble incised wounds. The accurate documentation and examination of these injuries may indicate the instrument involved, the relationship between the animal and the perpetrator, and the force of the stab. Situations in which this type of trauma occurs may involve social violence, accidents, hunting, veterinary medical management, and religious rituals. The causes of death related to this type of trauma include hypovolemic shock, pneumothorax, or asphyxiation due to aspiration of blood. Necropsy findings should provide objective and unbiased information about the cause and manner of death to aid the investigation and further judgment of a possible crime.
锐器伤是指使用锐器对皮肤施加机械力而造成的损伤。锐器伤主要分为刺伤、切割伤、砍伤和治疗性伤口，在动物中比钝器伤更为少见。对伤口边缘的分析至关重要，尤其是在涉及多种损伤类型时。区分锐器伤和钝器伤可能很困难，因为撕裂伤可能类似于切割伤。对这些损伤进行准确记录和检查，可能会揭示所使用的工具、动物与行凶者之间的关系以及刺伤的力度。发生此类创伤的情况可能包括社会暴力、事故、狩猎、兽医医疗操作和宗教仪式。与此类创伤相关的死亡原因包括低血容量性休克、气胸或因血液吸入导致的窒息。尸检结果应提供关于死亡原因和方式的客观、无偏见信息，以协助调查和对可能犯罪的进一步判断。
