Cervical Spine

Question 1

Hangmans Fracture

Answer 1

Hyperextension of C2, and resulting fracture of pedicles of C2.

Question 2

AA Joint

Answer 2

C1-C2

Primary motion is rotation, atlas rotates about the dens

Almost no side bending or flexion/extension

Question 3

OA Joint

Answer 3

Occiput-C1

Flexion and Extension

Minor rotation and side bending Type 1-like

Question 4

C2-C7

Answer 4

Rotation and side bending occur usually in the same direction, due to uncinate processes

Type 2-like

Question 5

Cervical Segment Exam

Answer 5

Left rotation induced by anterior pressure on posterior aspect of right lateral mass

Translation from right to left—->SB R

Question 6

Open Mouth Radiograph

Answer 6

Lateral masses of C1 should not overhand (extend wider than) the lateral masses of C2. If present, this is indicative of a burst fracture

Question 7

45 Degree Oblique Views for Radiographs

Answer 7

-Right POSTERIOR oblique demonstrates the left foramina

Posterior obliques demonstrate the foramina opposite to your patient positioning

-Right ANTERIOR oblique demonstrates the right foramina

Anterior obliques demonstrate the foramina on the same side as your patient positioning
