Q

BONUS: why do we rotate the patient in the grashey?

A
31
Q

Inferosuperior axillary position is also known as the

A

west point projection

32
Q

(T/F) we use a breathing technique for transthoracic lateral projection

A

True

32
Q

what do we see in profile on the inferosuperior projection?

A
33
Q

What is an alternative to the breathing technique of a transthoracic?

A

Tell the patient to hold there breath
to expose on full inspiration

34
Q

What is the CR for transthoracic?

A

surgical neck (or mid-diaphysis)

35
Q

In a Grashey we oblique the patient

A

35 to 45 degrees toward affected side
LPO and RPO

36
Q

In a Neer we oblique the patient

A

oblique the patient 45 to 60 degrees depending on the patient
RAO/ LAO
10 to 15 degrees caudal angle

37
Q

LPO/RPO oblique 45 degree angle, projection is

A

Grashey

38
Q

RAO/LAO 45 degree oblique, with a 10-to-15-degree tube angle projection is

A

NEER or Y view

39
Q

For internal rotation how is the hand?

A
39
Q

If you are working in the ED and the patient comes in with severe abdominal and shoulder pain he or she is unable to stand for the upright projections and you have positioned the patient for a shoulder projection with the humeral epicondyles parallel to the IR with the CR being 1 Inches inferior to the coracoid. This projection would be?

A

External or AP
(keyword to this is the epicondyle placement)

40
Q

your patient is in a 45-degree posterior oblique position with the affected side closest to the IR. The humeral epicondyles are parallel to the image receptor. CR is 2 inches inferior and 2 inches medial to the supralateral side of the scapula. Which view would this be?

A

Grashey
(hint is the CR and epicondyles)

41
Q

superstinatus view how is the scapula to the IR?

A

perpendicular
(because of the oblique)

41
Q

For external rotation how is the hand?

A
42
Q

What is most inferior portion in the shoulder?

A
43
Q

What is the anterior portion of the shoulder?

A

coracoid process

44
Q

what is the most posterior portion of the shoulder?

A

acromion

45
Q

What are the inferior angles and borders of the scapula?

A
46
Q

scapular notch

A
47
Q

coracoid

A
48
Q

The scapula spine extends laterally into a flattened triangle shape process known as the

A

acromion

49
Q

what kind of joint is the scapulohumeral (glenohumeral) joint?

A

Ball and socket
freely moveable (diarthrodial)

50
Q

What kind of joints are the AC and SC joints?

A

plane or gliding
freely moveable (diarthrodial)

51
Q

what kind of joints are the radioulnar joint?

A
52
Q

Inferosuperior axillary projection is

A

the axillary
(Mayo shoots this superoinferior)
Coracoid should be up and flipped to the right side

53
Q

Where are the AC and SC joint located?

A
54
Q

CR for internal shoulder

A

1 inch below the coracoid

55
Q

CR for a NEER view

A

mid-scapula
angle 10-15 degree caudad

56
Q

CR for Axial clavicle

A

mid clavicle
15 to 30 degrees cephalad
hyperstenic 15-20 degrees
asthenic 25 to 30 degrees

57
Q

how many projections for AC joint?

A

2 projections
one without weights (WOW)
one with weight bearing
14x17 inches landscape

58
Q

what do we do for a better divergent beam on AC joints to include both joints?

A

72 inch SID

59
Q

Bursitis

A

Inflammation of bursar
Fluid filled sacs enclosing the joints

60
Q

if you can angle for a clavicle you can position the patient to be

A

lordotic

61
Q

Idiopathic chronic adhesive capsulitis
(Frozen shoulder)

A

Chronic inflammation around joint
Causes pain and limitation in motion
(Idiopathic means unknown)

62
Q

Osteoarthritis

A

Degenerative joint disease (DJD)
Non inflammatory characterized by gradual deterioration of cartilage
Most common type of arthritis, normal with age

63
Q

Osteopetrosis

A

Reduction of quantity of bone
More likely to have fx’s

64
Q

Rotator cuff

A

Limits range of motion in shoulder
Injury to shoulder muscles:
Teres minor, supraspinatus, infraspinatus, subcapularis.

65
Q

Shoulder dislocation

A

Traumatic removal of humeral head from glenoid cavity
95% are anterior (humeral head is anterior to glenoid cavity)
