摘要： 目的探讨螺旋CT(SCT)三维(3D)成像技术在法医疑难骨外伤中的诊断价值。方法选择11例骨外伤病人进行X线及螺旋CT3D检查,观察和分析骨折的位置、数量及性质。结果11例中,X线检查共发现肋骨骨折34处,肩胛骨骨折1处,鼻骨骨折2处,掌骨不完全性骨折1处,左胫、腓骨骨折1处,耻骨骨折1处。CT检查共发现肋骨骨折47处,肩胛骨粉碎性骨折1处,鼻骨骨折明显移位1处,排除骨折1处,上颌骨骨折1处,掌骨完全性骨折1处,左胫、腓骨陈旧性骨折1处,骶骼关节脱位1处,第5腰椎椎弓根骨折1处。结合三维图像,冠位状及矢位状重组图像清晰地显示出骨折线的部位、数量、性质和错位、复原等情况。结论螺旋CT三维成像应用对法医复杂骨外伤的客观诊断非常有效,优于常规X线检查。

Abstract: Objective To investigate forensic diagnosis application of three-dimentional reconstruction with spiral computed tomography in fracture of anatomical complicated bones. Methods Selected eleven patients of bone fracture who were examined with SCT 3D and conventional X-ray examination. The location, number and characteristics were observed and analyzed. Results In all of eleven patients with bone fractures, X-ray examination could detect thirty-four rib fracture, one scapula fracture,two nasal fracture, one metacarpal bone incomplete fracture and one left tibia-fibula fracture, one pubis fracture. While there were forty-seven rib fracture, one scapula smash fracture, one nasal fracture with obvious displacement and eliminate one misplace, one left tibia-fibula obsolete fracture and one sacroiliac joint dislocation, one No 5 lumbar vertebrae pedicle of vertebrae arch fracture. Combining 3D reconstruction images, coronary and sagittal reconstruction images could show clearly the fracture line, location of fracture, number of fracture, displacement and recovery. Conclusion 3D reconstruction technique of SCT is a very useful examination method in the objective forensic diagnosis of anatomical complicated bones fracture, it excels the routine X-ray examination.
