SEThis study measured the diagnosis performance characteristics and reliability of 2-dimensional（2DCT）and 3-dimensional（3DCT）computed tomography images and modeling of coronoid fractions.METHODThe treating surgeon and first assistant evaluated 28 fractions for fracture type，specific characteristics，and proposed treatment.观察者对骨折进行了4次评估：第一次基于2DCT计算机图像和X线片;第二次添加3DCT图像;第三次添加3D模型;最后基于术中暴露，这被视为参考标准。此外，3DCT重建提高了观察员之间的可靠性骨折的分类，特点，并提出treatment.CONCLUSIONMore复杂的图像和建模提高了可靠性，但不准确性时，冠状骨折的特点。
PURPOSEThis study measured the diagnostic performance characteristics and reliability of 2-dimensional (2DCT) and 3-dimensional (3DCT) computed tomography images and modeling of coronoid fractures.METHODThe treating surgeon and first assistant evaluated 28 fractures for fracture type, specific characteristics, and proposed treatment. The observers evaluated the fractures 4 times: first based upon 2DCT computed images and radiographs; second with the addition of 3DCT images; third with the addition of 3D models; and finally based upon intra-operative exposure, which was considered the reference standard.RESULTSThe diagnostic performance characteristics did not improve with more sophisticate imaging and models. The addition of 3DCT reconstructions improved the inter-observer reliability for fracture classification, characteristics, and proposed treatment.CONCLUSIONMore sophisticated images and modeling improved reliability but not accuracy when characterizing coronoid fractures.
