Shoulder AP

breathing instructions

transthoracic lateral

breathing instructions

ideal: minimum 3 second exposure

with patient breathing normally to blur ribs and lung markings

otherwise: deep inspiration

transthoracic lateral

position

supine or upright lateral

affected arm closer to IR

unaffected limb elevated

unaffected shoulder higher than injured shoulder

transthoracic lateral

CR

ideal: perpendicular

pt unable to elevate unaffected shoulder: 10 to 15 degree angle (Merrill's textbook says cephalad but I'm still convinced it's an error. I will do further research. Direction will not be on test.)

inferosuperior axial projection (Lawrence method)

Axillary view

position

pt supine on radiolucent support

arm abducted 90 degrees w/external rotation

inferosuperior axial

CR

horizontal

medial angulation of 15 to 30 degrees

enters axilla

more abduction of humerus = more angulation

PA Oblique

Shoulder Scapular Y

purpose?

scapular Y

Where should the humeral head be?

Scapular Y

position

pt in 45 to 60 degree anterior oblique

affected shoulder closer to IR

scapular Y

CR

scapular Y

demonstrates

scapula in lateral profile

scapular body not overlapped on thorax

AP AC Joints (Pearson)

position

must be upright to demonstrate jt separation

center on MSP@ level of AC joints

AC joints

SID

72 inches

to decrease magnification

AC joints

2 images

with and without weights

5 to 8 pounds affixed to the wrists

clavicle AP

breathing

expiration

more uniform density

clavicle AP axial

breathing

deep inspiration

elevates clavicles

AP axial clavicle

CR

15 to 30 degrees cephalic

thinner pt = more angle

AP scapula

position

abduct arm 90 degrees

flex elbow

AP scapula

CR

perpendicular to a point 2 inches

inferior to coracoid process

lateral scapula

position

just like scapular Y

except make sure the humerus is out of the way

flex elbow and place back of hand on posterior thorax

AP scapula
