Answer 2

24 x 30 portrait
minimum 3 seconds exposure time
Cr: perpendicular to midscapula, 2 inches inferior to coracoid process; 2 inches medial from lateral border of patient
Orthostatic breathing

Question 3

AP scapula eval.

Answer 3

Hand supination evidenced by lateral portion of scapula free of superimposition
- medial portion of scapula seen through thoraxic structures
- affected hand abducted 90 deg.

Question 4

Lateral scapula

Answer 4

24 x 30 portrait
Suspend respiration during exposure
- palpate superior angle of scapula and AC joint articulation. Draw an imaginary line and rotate until it is perpenducular to IR (45 deg rotation)
CR: mid vertebral border of scapula

Question 5

Lateral scapula eval

Answer 5

Entire scapula visualized
- true lateral evidenced by direct superimposition of lateral and medial borders
- body of scapula should be in profile, free of superimpsition by ribs

Question 6

Hand rotation effect (AP shoulder)

Answer 6

external rotation: greater tubercle is seen in profile

neutral: greater tubercle moves medially

internal: greater tubercle fully superimposed over humeral neck

Question 7

Ap shoulder - external rotation (basic)

Answer 7

24 x 30 landscape
CR: perpendicular to IR, directed 1 inch inferior to coracoid process
Suspended breathing

Question 8

AP shoulder eval - external rotation

Answer 8

Full external rotation evdienced by greater tubercle in fill profile
- lesser tubercle superimposed over humeral head

Question 9

AP shoulder eval - internal rotation

Answer 9

full internal rotation evidenced by lesser tubercle visualized in full profile
- Greater tubercle superimposed over humeral head

Question 10

AP shoulder eval - neutral rotation (Basic)

Answer 10

24 x 30 portrait
CR: midscupulahumeral joint (3/4 inch inferior and slighty lateral to coracoid)

Question 11

AP shoulder - neutral rotation eval

Answer 11

both greater and lesser tubercles superimposed by humeral head.

Question 12

Glenoid cavity basic

Answer 12

18 x 24 landscape
rotate body 35-45 degrees toward effected side
CR: perpendicular to IR, directed to scapulohumeral joint (2 inches inferior and 2 inches medial from superolateral border of shoulder)
suspended respiration

Question 13

glenoid cavity eval

Answer 13

glenois cavity seen in profile without superimposition of humeral head
- scapulahumeral joint space is open
- anterior and posterior rims of cavity are superimposed

Question 14

Trans-scapular Y view - shoulder (PAO) basic

Answer 14

24 x 30 portrait
obliquety may randge from 45-60 degrees
palpate superior angle to scapula and AC joint, draw and imaginary line; oblique until line is perpendicular to IR
CR: perpendicular directed to scapulohumeral joint (2 inches below AC joint)

Question 15

Y view eval

Answer 15

• hmeral head should be superimposed over base of Y if no dislocation
• acromion and coracoid should appear symetric upper limbs of the Y

Question 16

inferosuperior basic

Answer 16

18 x 24 landscape
patient supine with shoulder raised 2 inches form tabletop
Arm abducted 90 deg. and external rotation
suspended respiration during exposure
CR: medially 25-30 deg, cntered horizontally to axilla and humeral head.

Question 17

inferosuperior eval

Answer 17

Question 21

AP axial clavicle eval

Answer 21

Correct angulation projects most of clvicle above the scapula and 2nd and 3rd ribs
only medial portio is superimposed by first and seocnd ribs
