Flashcards in Procedures Spine Review Deck (28):
1

Why do we utilize a 72" SID for lateral projection

Compensate for oid reduce mag

2

What is preferred SID for XTable lateral projection

10ft

3

What are 2 ways to move shoulders down for erect lat CSpine

Holding weights
Expiration

4

Why do we tip chin up for AP CSpine

To superimpose mandible and base of skull to visualize C3-T1

5

What landmarks are utilized for George projection

Thyroid Cartilage
Gonion
????????

6

When do you perform a Fuch's?

When your patient is perfectly positioned, but the tip of the teeth will not clear the dens to visualize the whole thing

7

What is the main structural difference of C1 compared to all other vertebra

C1 does not have a body. Instead it is replaced by an arch of bone is located where the body is usually found

8

What region of spine is demonstrated in Swimmers

C3-T3, Cervicothoracic region

9

PP
Swimmers

pt recumbent
true lateral with no rotation of head/shoulders
entire spine // to table
dependent arm up, under head
independent arm down at side

10

On which projection is breathing technique used

Lateral TSpine

11

What additional structure is foundon TSpine that is not found on any other vertebrae

Facets and Demi facets for rib articulation

12

Why do we flex knees for AP LSS

Minimize lordotic curve

13

Why do we place a lead strip behind the pt for the lateral projection

Minimize scatter

14

Can-Shaped vertebra is caused by what positioning error on a lateral projection

Spine is not true lateral/parallel to table

15

What are 2 parts of intervertebral discs

annulus fibrosis
nucleus pulposus

16

intervertebral foramen are formed by what 2 specific parts

superior and inferior vertebral notches

17

2 main parts of a typical vertebra

vertebral body
vertebral arch

18

What is the difference in appearance of spinous processes of C,T,L spine

C-Bifid tips
T-pointy and more vertical
L-more blunt and larger

19

Scoliosis

Abnormal lateral curvature of the spine

20

Lordosis

Abnormal lordotic curvature of the lumbar spine
Increased concavity

21

Kyphosis

abnormal thoracic curvature of thoracic spine
increased covexity

22

Spondylolysis

breakdown of pars interarticularis
demoed on oblique LSS

23

spondylolisthesis

Forward slippage of 1 vertebra on another
Usually occurs at L5-S1

24

Spina Bifida

Failure of 2 lamina to unite causing an opening where the spinous process is usually found

25

Jefferson's fx

Comminuted fx
occurs as a result of axial loading
anterior and posterior arches of C1 are fractured as skull slams into ring

26

Hangman's fx

fx through pedicles of C2 with or without subluxation of C2-3
occurs when neck is extremely hyperextended
dens is pressing posteriorly into brain stem

27

Clay shoveler's fx

caused by hyperflexion of neck
avulsion of spinous processes of C6,7, or T1
Best demoed on a lateral CSpine projection
