摘要： 目的 研究Bennett骨折与Rolando骨折的致伤方式，探讨第一掌骨基底部骨折致伤方式推断的鉴定原则。 方法 收集、整理Bennett骨折与Rolando骨折的鉴定案件共31例。对19例Bennett骨折与12例Rolando骨折的致伤方式进行归类、整理，并对各种致伤方式进行分类统计。 结果 19例Bennett骨折与12例Rolando骨折致伤方式包括三种：拳击他人过程中第一掌骨头撞击硬物、摔倒过程中手握拳时第一掌骨头撞击硬物以及被他人持硬物击打中握拳时的第一掌骨头。 结论 Bennett骨折和Rolando骨折的致伤机制多为握拳时暴力作用于第一掌骨头并沿掌骨纵轴方向传导至基底部形成。在进行致伤方式推断时应注重确认委托事项。

Abstract: Objective To study the injury manners of Bennett fracture and Rolando fracture and explore its identification principle of the first metacarpal base fractures. Methods Totally 31 cases of Bennett fracture and Rolando fracture were collected. The injury manners of cases of 19 Bennett fractures and 12 Rolando fracture were classified, and various injury manners were analysed statistically. Results The injury manners of the cases of 19 Bennett fracture and 12 Rolando fracture were divided into three types, including the first metacarpus hit hard objects during a punching, the first metacarpus hit hard objects when making fists and fell, or the first metacarpus was punched by hard objects when making fists. Conclusion The injury mechanism of Bennett fracture and Rolando fracture is formed by a force on the first metacarpus when making fists, which transmits to the basilar part along the vertical axis of metacarpus. The inference of injury manners should be focused on the confirmation of entrusted matters.
