The modified odontoid view: an alternative visualization of the atlantoaxial joint.
The sensitivity of the cross table lateral view (CTLV) alone, as a determinant in the radiographic disposition in patients with cervical spine fracture/dislocation has been challenged. A cervical spine trauma series that includes the CTLV, the anteroposterior view (APV), and the open-mouth view (OMV) has been suggested. Whereas the CTLV and APV present no difficulty, the OMV is often not possible in the uncooperative or unconscious patient, or in those patients with rigid forms of neck support. The modified odontoid view (MOV) can replace the OMV in these patients. The MOV allows for satisfactory visualization of the C1/C2 complex and is easily obtained as a portable technique. In addition, it requires neither patient cooperation nor neck movement. The technique is described and its interpretation reviewed.
