摘要
目的探讨分析隐匿性肋骨骨折多层螺旋CT检查的最佳时间窗,为临床法医学鉴定提供客观依据。方法回顾性分析胸外伤所致肋骨骨折的105例患者,患者均于伤后一周之内进行第一次MSCT检查,并于1周后进行多时间窗复查。将复查与第一次诊断肋骨骨折数量之间存在差异的患者纳入差异组,比较分析差异组在不同时间窗内MSCT检查隐匿性肋骨骨折数量差异是否存在统计学意义。结果 MSCT不同时间窗对隐匿性肋骨骨折检查的结果是不同的,第2、7、8、大于8周与第1周、第5、6周与第4周所检出的肋骨骨折数差异不存在统计学意义(P>0.05);伤后3~6周与第1周、3~6周与第2周、4~6周与第3周检查结果之间差异均存在统计学意义(P<0.05)。结论伤后4~6周是隐匿性骨折检查的最佳时间窗,这为法医学肋骨骨折鉴定提供了理论依据。
Objective To explore MSCT optimal examination time window for patients with occult rib fracture,and provide objective evidence for forensic injury.Methods Totally 105 cases with chest trauma were retrospectively analysed.They were examined in the first week after trauma and re-examined in different time windows by MSCT.The quantities of occult rib fractures in the first examination were compared to those in re-examinations.Results The quantities of occult rib fractures at different inspection time windows were mostly different.There was no statistically significant between the quantities of rib fractures in the first week and the second week,the first week and the sixth week later,the fourth week and the fifth to sixth weeks（P〉0.05）.There was statistically significant between the quantities of rib fractures in the first week and the thrid to sixth weeks,the second week and the third to sixth weeks,the third week and the fourth to sixth weeks（P〈0.05）.Conclusion The result of the study imply that the fourth to sixth week is the optimal time window of MSCT examination in the occult rib fracture.
