常见相交损伤顺序的法医学探讨

Forensic Study of Common Intersecting Injury Sequences

相交骨折线的研究比较成熟,其理论依据也充分,但对相交创口、皮下出血的研究相对较少;笔者在实际检案过程中对相交骨折、创口、皮下出血的情况进行观察分析,研究他们顺序表现的各自特点和推断依据。研究发现截断处骨折线的形成存在先后顺序,被截断的相交骨折线后形成,截断之处很可能不是外力直接作用点;未被截断的相交骨折线同时、先后形成均有可能,对合后的相交骨折线错位明显的后形成;相交创口因创缘、创腔截断、错位,或是医源性的有意截断的后形成;先形成的皮下出血更容易表现为变形或被截断;即被截断的骨折线、创口往往较后形成,医源性的有意截断的后形成,较早形成的皮下出血更容易被截断。

In forensic practice,the study of intersecting fracture lines is mature and its theoretical basis is suffi cient,but the study of intersecting wounds and subcutaneous hemorrhage is few relatively.Through the observation and analysis of intersecting fractures,wounds and subcutaneous hemorrhage,the author studied their respective characteristics and judgment basis.According to the actual work of the author,the relevant situation was observed and analyzed in the actual investigation process.The fracture lines at the blocked places were in a sequence,the intersecting fracture lines were formed after they were blocked,and the blocked places were probably not the point of direct action of external forces.It is possible for the closed intersecting fracture line,the obvious dislocation fracture line formed is later.Dislocation formation of intersecting wounds blocked due to traumatic edge,wound cavity,or iatrogenic intentional blocked.Subcutaneous hemorrhage that forms fi rst is more likely to be deformed or blocked.That is to say,the blocked fracture line and wound often form later,iatrogenic intentional blocked form later,and the subcutaneous hemorrhage formed earlier is more likely to be blocked.It is of great signifi cance to fully understand and distinguish the sequence of various injuries in order to reconstruct the case and reproduce the facts.
