Shoudler (ap, Oblique And Axial) Flashcards
(25 cards)
Structures for AP
Proximal 1/3 humerus
Shoulder joint only: lateral 1/2 clavicle
Full shoulder girdle: full clavicle
ST
Superior portion of scapula/entire scapula
CR and CP AP
Cr: perp
Cp: 2.5 cm inferior to coracoid process
Adjusted medially for full clavicle
Torso rotation AP
Glenoid is oval shaped and SI on humeral head
1/2 of lateral scapula free of SI from thorax
Clavicle adjacent to spine
Humeral rotation
Depends on site
External: GT in profile laterally
Internal: LT in profile medially
Neutral : both GT and LT seen end on
No waist f/e AP
SSA SI on clavicle
No foreshortening of scapular body
Structures for AP oblq
Proximal 1/3 humerus
Lateral portion of scapula
Lateral ST
CR and CP AP oblq
Cr: perp
Cp: glenohumeral joint
Adequate torso rotation AP oblq
Open GH joint
Glenoid in profile, HH free from glenoid
1/3 coracoid process SI HH
Clavicle foreshortened/ s-shaped
Humeral rotation AP oblq
Internal, external and neutral
Depends on site
No waist f/e AP oblq
Superior margin of coracoid process aligned with superior margin of glenoid fossa
Structures for y shoulder series
Proximal 1/3 humerus, acromion, coracoid, glenoid and lateral clavicle
Lat ST
Structure for y view scapula series
Complete scapula
Lateral ST
CR and CP for y
Cr: perp
Cp: midscapula
Good torso rotation y view
Medial and lateral scapular borders SI and free from ribs/thorax
No waist f/e for y
Scapula not foreshortened
SSA SI over clavicle
Humerus abd/add y
Humerus // to scapula or abducted to be off scapula
Structures for axial
Glenoid cavity, coracoid process, scapular spine, acromion process, lateral clavicle
Proximal 1/3 humerus
ST margins
CR and CP axial
Cr: HB with medial angulation of 15-30 degrees
Cp: GH joint
BTP inferosuperior axial
GH joint open with min overlap
Base of coracoid in same plane as glenoid
Good external humeral rotation axial
LT in profile anteriorly
No waist f/e axial
AC joints SI mid HH
CR and CP for superioinferior axial
CR: 5-15 caudal
CP: GH joint
BTP superoinferior axial
GH joint open with min overlap
Base of coracoid in same plane as glenoid
Good external humeral rotation supero axial
LT in profile anteriorly
