CT of the main ligaments of the cervico-occipital hinge

The results of a CT-anatomical correlative study of the main ligaments of the cervico-occipital hinge are reported. CT criteria of normal ligamentous structure of this region are presented in axial, coronal and sagittal views with a special attention to the transverse ligament of the Atlas. Examples of pathological transverse ligaments are illustrated and emphasis is laid upon the better statement CT allows in such cases.
