攻击伤致掌骨闭合性骨折成伤机制

Injury mechanism analysis of closed metacarpal fractures caused by attack

攻击伤所致闭合性掌骨骨折在法医临床实践中时有发生,本文通过文献综述,发现攻击伤致闭合性掌骨骨折在第一到第五掌骨都可以出现。结合掌骨解剖、形态和生物力学详细地阐述了攻击伤所致闭合骨折的发生机制。司法鉴定中还应该注意当时手部皮肤伤情:有无皮下淤血、皮肤擦伤、挫伤、肿胀等情况,来判断是否为攻击伤所致。同时要结合其他佐证,比如证人、视频、致伤物等来还原受伤经过。以保证鉴定意见公正客观。

Closed metacarpal fractures caused by attack injuries occur frequently in forensic clinical practice.Through literature review,this paper found that closed metacarpal fractures caused by attack injuries can occur from the first to the fifth metacarpal bones.Combined with the anatomy,morphology and biomechanics of metacarpal bones,the mechanism of closed fractures caused by attack injuries was elaborated in detail.In the judicial appraisal,attention should also be paid to the skin injuries of the hands at the time:whether there was subcutaneous bruising,skin abrasions,contusions,swelling,etc.,to determine whether it was caused by attack injuries.At the same time,it is necessary to combine other supporting evidence,such as witnesses,videos,injuries,etc.,to restore the injury process to ensure that the appraisal opinion is fairand objective.
