Board Review II Flashcards
What happens to sidebending and rotation as you move down the C-spine?
Sidebending increases
Rotation decreases
What is the “Yes joint”?
OA
True or false: there is no disc between C1 and C2
True
What is the body of the axis (C2)?
Odontoid process (Dens)
What is the uncovertebral joint of Luschka? What is the clinical significance of these?
Lateral portion of vertebral bodies
Place of osteophyte formation
What are zygapophyseal joints?
Joint between the pillars
True or false: there are no type I SD in the cervical spine
True
True or false: since the OA has sidebending and rotational components in opposite directions, it is a type I SD
False
Why is the sidebending and rotational components to the same side with the C-spine?
Zygapophyseal joints
What is Spurling’s test?
Rotate and side bend to assess for nerve root impingement
What is the Wallenberg test?
- Test for vertebral artery insufficiency
- Head and neck are held in extension-rotation for 30 seconds
Spine of scapula = what T level?

What is the nipple dermatome?
T4
What is the umbilicus dermatome?
T10
What is the greatest amount of motion in the thoracic spine? Least?
Greatest = rotation Least = extension
What is the order of motions of the thoracic spine?
Rotation, side bending, flexion, extension
What vertebrae should be treated first with scoliosis?
The apex one
What is the difference between structural and functional scoliosis?
Structural = fixed
