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 characteristics of orbital fractures. Methods A total of 3 653 cases of orbital fractures were screened from 3 653 cases of forensic injuries. The cases were divided into 3 groups: group Ⅰ: burst fracture orbital fracture without orbital rim fracture; group Ⅱ: direct fracture with orbital fracture; Ⅲ Group: Complex fractures, both of the above two fractures. The results involved 50 cases of orbital fracture. Group Ⅰ 26 cases, accounting for 52%; group Ⅱ 1 9 cases, accounting for 38%; Ⅲ group 5 cases, accounting for 10%. Burst fractures within, more common under the wall, accounting for 96% of the wounds to fist more common, accounting for 78%, visual impairment and eyeball structure lighter. Direct external wall more common fracture, accounting for 56% of the more commonly used blunt instruments accounted for 63% of injury, visual acuity and eye damage heavier. Complex fractures of the wall can occur. Conclusion The degree of burst fracture is less than direct fracture and composite fracture, which may easily lead to misdiagnosis.
