If high-quality CT imaging is not available, a 3-view cervical spine series (antero-posterior, lateral, and odontoid views) is recommended.
Rocobado cephalometric analysis: (A) Subject with cranio-cervical posture equilibrium, posteroinferior angle formed by McGregor plane and odontoid plane, normal (101[degrees]); (B) Subject with posterior head-neck rotation (extension) and related posteroinferior angle reduction (86[degrees]).
The basion-dens interval (BDI, distance from basion to upper odontoid tip) should be <12 mm in 95% of patients.

The most common structural lesions were anterior atlantoaxial subluxation (30%), C1-C2 arthritis (22%) erosion of the odontoid process (18%), and apophyseal joint arthritis (16%).
MRI demonstrated a predominantly right-sided mass at C1 and C2, behind the odontoid, hyperintense on T2 weighted imaging, and compressing the upper cervical spinal cord.
The MRI also showed assimilation of the odontoid process of C2 and the C1 vertebral body.
In IGM 9563 the odontoid process in the cervical tube is anteriorly directed and inclined almost 45[degrees] as in G.
1a), the vertical axis must cross the following coordinates: vertex; odontoid process of the second cervical vertebra (C2); vertebral body of the 3rd lumbar vertebra and, at the same distance, within the support base, between the two soles; concomitantly, the scapular and gluteal planes are aligned.
sup][3] There is a report of the use of the Trachway device for awake tracheal intubation in a patient with a history of odontoid fracture.
Images were oriented in such a way that the vertical grid would go through the middle odontoid process and the nasopalatine foramen in the upper residual ridge; and in the lower residual ridge it would go horizontally through the menton orifice and vertically through the middle of the vertebra.
A hypoplastic odontoid process and thickened ligaments posterior to the odontoid, causing craniovertebral (CV) junction stenosis, were also observed (Fig.
