3b. Shoulder & Spine Views and Positioning Flashcards
what is the patient position for an supero-inferior axial shoulder
in terms of IR height, affected arm and head
seated with side affected next to IR
raise IR to mid thoracic height
affected arm abducted with elbow resting on table
head tilted away
what is the CR and CP of the supero-inferior axial shoulder
5-10* CR angle towards elbow
CP = glenohumeral joint
what is the position critique for the axial supero-inferior view of the shoulder
coracoid sitting up and acromion below HOH
what is the area critique for the axial supero-inferior view of the shoulder
humeral head and glenoid included
what is the patient position for an impingement view
PA
rotated unaffected side to bring line between medial scap border and AC joint perp to IR
what is the clinical indications for an impingement view
rotator cuff damage
impingement
what is the CR and CP of the impingement view
15-20* caudal angulation
2cm superior to the medial end of the scapula spine
what is the positioning critique for an impingement view
4 things
scapula in Y appearance
visualise supraspinatus outlet
acromion coracoid for Y arms and Humeral head superimposed at y base
what is the patient position for an anterior oblique SC joint
raise each side 10-15*
prone position
what is the clinical indications for an anterior oblique SC joint
joint separation/subluxation
dislocation/trauma/infection or deformity in absence of trauma
what is the CR and CP of the anterior oblique SC joint
center to raised side lateral to spine at T2/3 level
what is the positioning critique for the anterior oblique SC joint
want to see distance between manubrium and clavicle
what is the clinical indications for an serendipity view
suspected dislocation
what is the patient position for an serendipity view
supine
what is the CR and CP of the serendipity view
level of SC joints
angle 40* cranial
what is the positioning critique for the serendipity view
in terms of what shows good angle and what the clavicle should be like
good angle = bony structure seen without excessive distortion
medial ends of clavicle equidistant apart in same horizontal plane
what is the collimation for the serendipity view
medial ends of both clavicles laterally
inferior to include SC joint and part of manubrium
what is the area of interest for the serendipity view
entire SC joint
what is the clinical indications for an flexion/extension Lumbar view
spinal instability
spondylolisthesis
degree of motion of lumbar spine
what is the CR and CP of the flexion/extension Lumbar view
iliac crest/lower costals - same as lateral lumbar spine
what is the patient position for the flexion/extension Lumbar view
flexion = hips, shoulders, thighs drawn close together while flexing forwards
extension = arch back
what is the positioning critique for the flexion/extension Lumbar view
what shows that the spine is parallel to the IR and what shows no rotation
spinal column parallel to IR = open intervertebral foramina and joint spaces
no rotation = GSN superimposed and posterior vert bodies superimposed
what is the area of interest for the flexion/extension Lumbar view
T & L spine
some of iliac crests
