Test 2 - Shoulder girdle Flashcards
3 breathing techniques
orthostatic breathin
suspended inspiration
suspended expiration
AP scapula (basic info)
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
AP scapula eval.
Hand supination evidenced by lateral portion of scapula free of superimposition
- medial portion of scapula seen through thoraxic structures
- affected hand abducted 90 deg.
Lateral scapula
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
Lateral scapula eval
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
Hand rotation effect (AP shoulder)
external rotation: greater tubercle is seen in profile
neutral: greater tubercle moves medially
internal: greater tubercle fully superimposed over humeral neck
Ap shoulder - external rotation (basic)
24 x 30 landscape
CR: perpendicular to IR, directed 1 inch inferior to coracoid process
Suspended breathing
AP shoulder eval - external rotation
Full external rotation evdienced by greater tubercle in fill profile
- lesser tubercle superimposed over humeral head
AP shoulder eval - internal rotation
full internal rotation evidenced by lesser tubercle visualized in full profile
- Greater tubercle superimposed over humeral head
AP shoulder eval - neutral rotation (Basic)
24 x 30 portrait
CR: midscupulahumeral joint (3/4 inch inferior and slighty lateral to coracoid)
AP shoulder - neutral rotation eval
both greater and lesser tubercles superimposed by humeral head.
Glenoid cavity basic
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
glenoid cavity eval
glenois cavity seen in profile without superimposition of humeral head
- scapulahumeral joint space is open
- anterior and posterior rims of cavity are superimposed
Trans-scapular Y view - shoulder (PAO) basic
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)
Y view eval
- hmeral head should be superimposed over base of Y if no dislocation
- acromion and coracoid should appear symetric upper limbs of the Y
inferosuperior basic
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.
inferosuperior eval
- lesser tubercle profiled anteriorly
- correct CR angle evidenced by superimposition of superior and inferior borders of glenoid cavity
superoinferior
18 x 24 landscape
elbow flexed 90 deg
patient leaning over table
CR: 5-15 deg caudad, perpendicular to glenoid fossa
AP and AP axial clavicle
24 x 30 landscape
- AP: Cr perpendicular to mid-clavicle
- Axial: 15-30 deg cephalic midclavicle
AP clavicle eval
clavicle is demontrased without foreshortening
midclavicle is superimposed on the superior scapular angle
AP axial clavicle eval
Correct angulation projects most of clvicle above the scapula and 2nd and 3rd ribs
only medial portio is superimposed by first and seocnd ribs
AP + AP axial AC joints (basic)
18 x 24 landscape
CR: midpoint between AC joints, 1 inch above juglar notch
AXIAL; 15 deg cephalic
weights: 8-10lbs
AC joints eval
both AC jonts on same horizontal plane
- No rotation evidence by symetrical SC joints
