1

What is the goal of the lumbar spine radiograph?

identify or exclude anatomic abnormalities or disease processes of spine

2

What are the routine projects of the lumbar spine?

AP
Lateral views

3

What additional views may be needed?

right and left oblique
coned lateral view of lumboscral articulation

4

What does the right posterior oblique (RPO) and left posterior view (LPO) views demonstrate?

right: right sided structures
left: left sided structurers

5

What does the posterior oblique views image?

downside” facet joints closest to image receptor

6

What might the anterior oblique position be used for?

upside” facet joints farther from image receptor

7

Nose of scottie dog

transverse provess

8

Eye of scottie dog:

pedicle

9

Ear of scottie dog:

superior articular process

10

Neck of scottie dog:

pars interarticularis

11

Foreleg of scottie dog:

interior articular process

12

Body of scottie dog:

lamina and spinous process

13

Tail of scottie dog:

superior articular process of opposite side

14

Hind leg of scottie dog:

inferior articular process of opposite side

15

What is the imagining of choice for evaluating trauma patients?

CT

16

What can help localize injuries?

AP and lateral radiographs

17

If CT is normal, is an MRI necessary and why/why not?

no- b/c isolated ligamentous injuries rare in lumbar spine

18

What is the predominant site of vertebral fractures?

Thoracolumbar junction (T11–L2)

19

What is spondylolysis a defect of?

at pars interarticularis

20

What can a defect be?

Congenital (rare)
Traumatic
Stress fracture caused by chronic strain

21

What is the most common lumbar injury?

Stress fracture caused by chronic strain

22

What is spondylolosthesis?

forward displacement of one vertebra upon stationary vertebra beneath it
can also be called anterolisthesis

23

What is retrolisthesis?

posterior displacement of a vertebra

24

What percentage of patients have spondylolisthesis?

5-10%

25

Who is typically affected by spondylolisthesis?

children and adolescents
more apparent in those involved in athletics

26

What levels are most often involved in spondylolisthesis?

lower lumbar
L4-L5, L5-S1

27

Spondylolisthesis can also result from:

Congenital or developmental aberrations
Pathological processes
Degenerative changes

28

What is the usual clinical presentation of Spondylolisthesis?

Patient c/o pain after athletic activities or physical labor

29

What action reduces pain?

lumbar flexion- which reduces displacement

30

What can palpation of spinous process reveal?

rotation or deep depression
