AbstractFour different radiological diagnostic methods were compared as to their diagnostic relevance in the analysis of odontoid fractures. Thirty-one patients with fresh odontoid fractures were investigated using standard anteroposterior and lateral radiographs, conventional tomography, axial computerized tomography and two-dimensional reconstruction in the sagittal and the coronal planes. As a control, 13 patients without odontoid fractures were examined. The results of the different investigations were correlated with the actual (clinical and/or intra-operative) findings. The coefficients of correlation for the conventional tomography and two-dimensional reconstruction were kappa=0.774 and kappa=0.907, respectively. For conventional radiography and axial computerized tomography (CT), the coefficients were clearly lower, at kappa=0.364 and kappa=0.627, respectively. The less time-consuming CT examination with sagittal and coronal reconstructions is equivalent with respect to diagnostic accuracy and can, therefore, replace conventional tomography in the evaluation fractures.
