眼眶骨折的法医学鉴定研究(附50例分析)

Analysis on 50 cases of orbital fractures in forensic medical examination

目的 研究眼眶骨折的法医学特点。方法 从 3 653例损伤程度的法医学鉴定中筛选出涉及眼眶骨折的案例 ,分成 3组 :Ⅰ组 :爆裂性骨折 ,眼眶骨折而眶缘无骨折 ;Ⅱ组 :直接骨折 ,合并眶缘骨折 ;Ⅲ组 :复合骨折 ,上述两种骨折兼而有之。结果 涉及眶骨骨折 50例。Ⅰ组 2 6例 ,占 52 % ;Ⅱ组 1 9例 ,占 3 8% ;Ⅲ组 5例 ,占 1 0 %。爆裂性骨折以内、下壁多见 ,占 96% ,致伤物以拳脚多见 ,占 78% ,视力和眼球结构损伤较轻。直接骨折以外壁多见 ,占 56% ,致伤物以钝性工具多见占 63 % ,视力和眼球结构损伤较重。复合骨折各壁均可发生。结论 爆裂骨折损伤程度轻于直接骨折和复合骨折 ,容易引起误诊。

Objective To study the forensic medical features of orbital fracture Methods 50 cases of orbital fracture were collected from 3653 cases of forensic medical examination, and dividing into three groups: Group Ⅰ: blowout orbital fracture without fracture of orbital margin, Group Ⅱ: direct fracture with fracture of orbital margin; Group Ⅲ: complicated fracture with blowout fracture and direct fracture Resuls There were 26 cases in Group I (52%), 19 cases in group Ⅱ (38%), 5 cases in Group Ⅲ (10%) In group I, blowout fracture of interior wall and inferior wall were common with high injure rate (96%), mainly by cuff and kick (78%), and the degree of injury on vision and structure of eye balls were also slight In Group Ⅱ, direct fracture of lateral wall was often seen (56%) with serious degree of injury on vision and structure of eyeballs Blunt instruments caused 63% of this fracture Different kinds of fracture of orbital wall were found in Group Ⅲ Conclusion The degree of injury on blowout fracutre are slighter than that of direct fracture and complicated fracure, misdiagnose are more common in blowout fracture
