Q

Judet view

obturator oblique is the view you would want to evaluate the

A

anterior column, which is the iliopectineal line

also view you want for posterior wall.

19
Q

how does mortise differ from AP

A

you internally rotate at knee a little to get the toes to point forward. to get purely anterior of mortise

20
Q

what indicates a good lateral view of the ankle?

A

look at the talar dome, make sure it has good overlap with tibia

21
Q

How can you tell if you have an AP view of scapula?

A

scapula is protracted forward a little - 30 degrees of ante version

22
Q

what shoulder view would overcome the anterior tilt of the scapula?

23
Q

any time you are evaluating congruency of glenohumeral joint, you should get what view

A

axillary view

this view tells you where the glenoid and humerus are articulating

24
Q

If it’s too hard to abduct arm for axillary view - get a?

25
other than a dislocation, an axillary view can show you
bony bankart lesions
26
describe a scapular Y view of the shoulder
looking down the plane of scapula the corocoid, accromion and shaft of humerus form a Y shape
27
What is a Y view good for?
evaluation of shoulder pain, esp in impingement syndrome... you could look at the hook of the acromion
28
what kind of film is good to get (in particular) when evaluating osteoarthritis of the knee, and why?
WT BEARING AP | because it shows what they are actually experiencing in their knee when they are standing
29
How do you know if a film is wt bearing
look for the bb circle. if they are all stacked on the bottom= weigh bearing. (cassette was upright. as opposed to flat where bb's would be distributed randomly)
30
sunrise view of knee shows
patellofemoral joint
31
good lateral of the knee will show?
overlapping of femoral condyles
32
Blumensat's line is basically what? and what lives there
basically the notch of the knee cruciates live there
33
What are the sesamoid bones of the knee?
patella | fabella
34
where is the fabella found
knee | head of the lateral gastroc
35
Where does the fibula live in relation to the tibia
somewhat posterior
36
The Harris View looks at what bone? What is it used to evaluate
Calcaneus | for comminution and widening of calcaneous
37
Describe the scaphoid view
for evaluating scaphoid fx requires hand to be ulnar deviated it extends the scaphoid - so you're looking perpendicular to axis of scaphoid
38
Coupled movement of radial/ulnar deviation and movement of the scaphoid
ulnar deviation extends scaphoid | radial deviaiton flexes scaphoid
39
on a PA view, what does the scaphoid look like?
a ring - find sign of scapholunate dissociation
40
when asked to read an x ray, what do you want know? (2 things)
closed vs open | neurovascularly intact?
41
Lagging produces what type of bone healing?
primary bone healing
42
Casting will result in what type of bone healing?
Secondary bone healing with relative stability
43
When using a dynamic compression plate to compress, should you drill away or towards the fracture in the oblong hole?
away
44
a one third tubular plate put in after a lag screw in a distal fibula ORIF is used as a
neutralization plate
45
A buttress plate provides what type of compression
dynamic
46
The talus, scaphoid and 5th metatarsal base have what kind of blood supply
tenuous
