摘要： 目的 分析手舟骨骨折成伤机制的法医学鉴定要点，为法医学鉴定实践提供参考。 方法 选取2007—2011年在中国刑事警察学院物证鉴定中心鉴定后已结案的手舟骨骨折成伤机制鉴定案件共43例，对手舟骨骨折初诊漏、误诊情况，骨折分型，伴发损伤，成伤机制分歧点等方面进行分析。 结果 手舟骨骨折初诊漏、误诊率高，以腰部骨折最多见，成伤机制分歧主要集中于系外力直接打击还是倒地摔跌间接作用所致。 结论 手舟骨骨折多为跌倒时手掌着地致腕关节过度背伸所致。

Abstract: Objective To explore the key points of injury mechanism of scaphoid fracture in forensic expertise and to provide the references for forensic practices. Methods Forty-three cases of injury mechanism identification of scaphoid fracture were selected from 2007 to 2011 in Institute of Forensic Evidence, Chinese Criminal Police Academy. Following aspects were analyzed: missed diagnosis and misdiagnosis at first visit, fracture classifications, accompanying injuries and mechanism of injury. Results The rates of missed diagnosis and misdiagnosis were high in the cases of scaphoid fractures, most common in the fracture of the waist. The disagreement on mechanism of injury was whether it was due to direct impact or indirect effect by falling. Conclusion Wrist hyperextension due to fall with palm impact on the ground was the main cause of scaphoid fracture.
