  17. POSTERIOR OBLIQUE POSITION—GLENOID CAVITY: SHOULDER kVP
    Analog—75 ± 5 kV range

    Digital systems—75 to 85 kV range
  18. POSTERIOR OBLIQUE POSITION—GLENOID CAVITY: SHOULDER Part Position
    • Rotate body 35 ° to 45 ° toward affected side
    •  If the radiograph is performed with the patient in the supine position, place supports under elevated shoulder and hip to maintain this position.
    • Center midscapulohumeral joint to CR and to center of IR.
    • Adjust cassette so that top of IR is about 2 inches (5 cm) above shoulder and side of IR is about 2 inches (5 cm) from lateralborder of humerus.
    • Abduct arm slightly with arm in neutral rotation
  19. POSTERIOR OBLIQUE POSITION—GLENOID CAVITY: SHOULDER Anatomy Demonstrated:
    Glenoid cavity should be seen in profile without superimposition of humeral head.
  20. POSTERIOR OBLIQUE POSITION—GLENOID CAVITY: SHOULDER CR
    perpendicular to IR, centered to scapulohumeral joint, which is approximately 2 inches (5 cm) inferior and medial from the superolateral border of shoulder
  21. AP PROJECTION—NEUTRAL ROTATION: SHOULDER SID
    40 INCHES
  22. AP PROJECTION—NEUTRAL ROTATION: SHOULDER IR SIZE
    10X12
  23. AP PROJECTION—NEUTRAL ROTATION: SHOULDER kVP
    • 70-80 ANALOG
    • 75-80 DIGITAL
  24. AP PROJECTION—NEUTRAL ROTATION: SHOULDER Part Position•
    • Position patient to center scapulohumeral joint to IR
    • Place patient’s arm at side in “as is” neutral rotation.
    • (Epicon-dyles generally are approximately 45° to plane of IR.)
  25. AP PROJECTION—NEUTRAL ROTATION: SHOULDER CR POSITION
    • CR perpendicular to IR, directed to midscapulohumeral joint,
    • which is approximately 3 4 inch (2 cm) inferior and slightly lateral to coracoid process 
  26. TRANSTHORACIC LATERAL PROJECTION:SHOULDER IR SIZE
    10X12
  27. TRANSTHORACIC LATERAL PROJECTION:SHOULDER KvP
    • 75-+5 ANALOG
    • 75-85 DIGITAL
  28. TRANSTHORACIC LATERAL PROJECTION:SHOULDER Part Position•
    • Place affected arm at patient’s side in neutral rotation; drop shoulder if possible.
    • Raise opposite arm and place hand over top of head; elevate shoulder as much as possible to prevent superimposition of affected shoulder.
    • Center surgical neck and center of IR to CR as projected through thorax.              Ensure that thorax is in a true lateral position or has slight ante- rior rotation of unaffected shoulder to minimize superimposition of humerus by thoracic vertebrae.
  29. TRANSTHORACIC LATERAL PROJECTION:SHOULDER CR POSITION
    CR perpendicular to IR, directed through thorax to level of affected surgical neck
