Q

Name the 2 pelvic lines of symmetry

A

(anterior) Iliopectineal line -> follows the pelvic brim
(posterior) Ilioischial line

Asymmetry here could be due to # of poor patient orientation.

Q

Beam angulation for AP sacrum and AP coccyx

A 
Sacrum = 15 caudad
Coccyx = 15 cephalad

Due to curvature of the anatomy.

Q

Lumbarisation of S1

A

Less common then sacralisation

6 lumbar vertebrae.

  • Increased IV’s
  • Increased facet joints.
  • squaring of vertebral body.

16
Q

What direction do sacral # typically go in ?

A

anterior angulation.

17
Q

What projection is best used to asses a sacral #

A

lateral

less SI

18
Q

Best view to asses a acetabular #

A

Judet’s view (AP Int oblique pelvis)

19
Q

Positioning for Judet’s view

A

45 obliquity, UNAFFLICTED side raised.
LPO/RPO
Meaning patient is resting on injured side … painful

20
Q

Modified Judet’s positioning

A

Normal postiont with vertical beam and then

External AP oblique. Patient is rolled onto unaffected side. the afflicted side will be raised

IR out of bucky.

patient is never rolled onto afflicted side

21
Q

What does an internal (illiac) Judet show?

A

Anterior aspect of iliopubic collumn and post acetabulum

Obturator view

22
Q

WHat does an external (obturator) judets show?

A

Post ilioischial collumn and anterior acetabulum.

Illiac view

23
Q

MOI for acetabular #

A

Sagital force smashes femur into pelvis

Possible damage to viscera and vascularisation (iliofemoral Aa.)

24
Q

What does the collumn and wall indicate in a judet view?

A

Wall indicated # (acetabular) and collumn indicates displacement.

25
Q

How many projections is taken in a Judet view?

A

2 Internal and external.

26
Q

In a RPO judet which Illiac crest is foreshortned and which is elongated?

A

Right is elongated and left is foreshortened.

27
Q

Spondylosis

A

Pars interartuclaris #

28
Q

Spondyloptosis

A

Grade 5 spondylolisthesis

29
Q

grade 5 spondylolisthesis

A

Spondyloptosis

30
Q

Pars Interarticularis #

A

Spondylosis

31
Q

What projection is the scotty dog best viewed on?

A

Lumbar oblique

32
Q

Describe orientation of pars interarticularis

A

base of facet joint

Found at posterior aspect of spine near the lamina.

33
Q

What type of # is a pars interarticularis #?

A

Stress

34
Q

What does lolithesis mean?

A

Movement

anteror/posterothesis.

35
Q

Spondyloptosis radiographic appearance

A

Rounding of L5 Vertebral body

immense nerve stress.

36
Q

What is Coccydynia

A

Tail bone pain

More prominent in females
Causes nerve tension

Can be caused by # allignment or natural variance caused by curvature of the coccyx.

37
Q

What view is used for coccydina and what is the best treatment?

A

Lat and AP coccyx.

Surgery or physio to REDUCE symptoms.

38
Q

If a patient cant straighten their legs for an AP sacrum then what has to occur?

A

Beam moves from a 15 caudad angulation to a perpendicular beam

although SI joints will be more displaced.
