Answer 8

radial head and neck are superimposed

Question 9

elbow partial flexion

Answer 9

used for dislocation to reduce range of motion
-humerus parallel: demonstrate distal humerus
-forearm is parallel: demonstrate proximal radius

Answer 11

-only see the posterior fat pad when there’s a fracture

Question 12

AP humerus

Answer 12

-epicondyles parallel
-shows greater tubercle
-supinate hand

Question 13

lateral humerus

Answer 13

-internal rotation of arm
-shows lesser tubercle
-epicondyles perpendicular ( superimposed)

Question 14

transthoraic

Answer 14

fracture for upper 1/3

Question 15

shoulder Non trauma

Answer 15

AP internal = lesser tubercle is shown
AP external = greater tubercle is shown
CR= 1inch below coracoid process

Question 16

Posterior oblique Grashey shoulder

Answer 16

-Glenoid cavity
-30-44 degree toward IR

Question 17

Y view PA oblique (scapular Y)

Answer 17

45-60 oblique
-AP= trauma
-PA= reduces breast tissue dose
-USED for shoulder dislocation

Question 18

Inferosuperior axial (axiallary)

Answer 18

-lawrence method

Question 21

lateral scapula

Answer 21

-45-60 rotation
-body of scalp perp to IR
- arm is drawn forward to demonstrate body, acromion and coracoid
