Purpose:
This study measured the diagnostic performance characteristics and reliability of 2-dimensional (2DCT) and 3-dimensional (3DCT) computed tomography images and modeling of coronoid fractures.
Method:
The 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.
Results:
The 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.
Conclusion:
More sophisticated images and modeling improved reliability but not accuracy when characterizing coronoid fractures.

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
