1. MODULE 2
Cervical Spine

2. Normal Anatomy: typical and atypical features
Extraspinal points of assessment
Sella turcica - maximum 16 X 12, double floor sign, any erosion
Lung apices
paravertebral calcification - carotid bifurcation
Can’t see vertebral artery calcification

5. Series Minimum - three (APOM, APLC, Lateral)
Standard - five (APOM, APLC, Lateral, Right/Left Obliques with radiating signs and symptoms)
Alternative - (APOM, APLC, Lateral, Flexion/Extension to document motion and stability)
Standard - seven (Trauma series, 9 views)

6. Most underutilized study is the Pillar view
Most common cervical spine fracture is facets
17% cervical fracture at C7
6/10 fractures found
2.4 fractures are the average
You see a cervical spine fracture, stabilize and
transport. Stop the series.

7. Lines of Mensuration ADI Decrease degenerative joint disease
Increase trauma
occipitalization
Down’s Syndrome
20% born without transverse ligament
25% have small posterior arch

12. Lines of Mensuration Continued
Pharyngeal infection
Ankylosing spondylitis
Rheumatoid arthritis
Psoriasis
Reiter’s

13. Lines of Mensuration Continued
George’s Line
Posterior Cervical Line (spinolaminar joint line)
Sagittal diameter, not useful
Atlanto-axial alignment
C1 fracture
Cervical spine gravity line
