MSCT对压曲型肋骨骨折诊断的法医学意义

The forensic significance of MSCT in diagnosis of buckle rib fracture

目的总结压曲型肋骨骨折的MSCT表现,探讨肋骨位MPR重建在压曲型肋骨骨折中的诊断价值,并评价MSCT对压曲型肋骨骨折诊断的法医学意义。方法纳入由复查CT确诊的压曲型骨折患者61例,记录骨折的类型及部位,比较使用肋骨位MPR重建与未使用肋骨位重建对该型骨折的诊断准确率。结果61例患者共检出压曲型肋骨骨折236处。其中A型66处,表现为肋骨内缘骨皮质弯曲;B型124处,表现为肋骨內缘骨皮质的扭折;C型46处,表现为內缘骨皮质断裂。使用肋骨位MPR重建组诊断准确率为94.5%,显著高于未使用肋骨位重建组的88.6%(P<0.05)。结论 MSCT对压曲型肋骨骨折的法医学鉴定有重要意义,结合肋骨位MPR重建有助于压曲型肋骨骨折的检出。

Objective To summarize the MSCT manifestations of buckle rib fracture, to explore the diagnostic value of rib view MPR reconstruction in the buckle rib fracture, and to assess the forensic significance of MSCT in the buckle rib fracture. Methods A total of 61 patients with buckle rib fracture diagnosed by CT were enrolled. The type and location of fractures were recorded. The accuracy of MPR reconstruction with and without rib view were compared. Results A total of236 buckle rib fractures were detected in 61 patients. Type A buckle fracture(66) showed the inner cortical bone bending;type B(124) showed the inner cortical bone kinking;type C(46) showed the inner cortical bone disruption. The diagnostic accuracy of the MPR reconstruction with rib view(94.5%) was significantly higher than that of the unused ribs view reconstruction group(88.6%(P<0.05). Conclusion MSCT has important forensic significance in the diagnosis of buckle rib fracture. Rib view MPR reconstruction is helpful for the detection of buckle rib fracture.
