• Radiography of the shoulder Girdle
• Shoulder joint
• AP external rotation ( non trauma)
• AP internal rotation ( non trauma)
• AP Gleno- humeral joint
• Lateral Transthoracic
• Axial
• AP/ PA AP axial clavicle
• Acromioclavicular joints

4

• AP External rotation

Exposure Factors
Kv mAs FFD (cm) Grid Focus Cassette
75 12 100 Yes Fine 24x30
Patient position

• Erect or Supine
• Part position
• Center coracoid process to cassette
• rotate patient slightly towards
• the affected side
• ?Adjust hand in External rotation to obtain
• an AP projection of proximal humerus
• ?Adjust hand in Internal rotation for lateral
• projection of proximal humerus

5

• Central Ray
• Perpendicular
• Center Point
• 1 inch inferior to the Coracoid process
• Structures shown
• Internal rotation ( AP proximal humerus ,2/3 of
  clavicle , humeral head in Relation to gelnoid
  cavity)
• External rotation ( AP proximal humerus ,2/3 of
  clavicle , humeral head inRelation to gelnoid
  cavity)

6

• Glenohumeral joint

Exposure Factors
Kv mAs FFD (cm) Grid Focus Cassette
80 8 100 No Fine 18x24 cm
85 12 100 Yes Fine 18x24 cm
Patient Position

• Erect or Supine

• Part position
• Rotate patient 35- 45 degrees towards affected
  side
• Dorsal surface of scapula parallel to film holder

• Place arm in normal anatomical position
• Humeral epicondyles equidistance from the film
  holder

• Central Ray
• Perpendicular
• Center Point
• TO Gleno-humeral joint
• Structures shown
• Gleno-humeral joint

AP Glenohumeral joint

• Transthoracic Lateral ( Trauma )

( For Fracture dislocation )
Exposure Factors
Kv mAs FFD (cm) Grid Focus Cassette
85 40 100 Yes Fine 18x24 cm
Patient position

• Erect or Supine

Part position Raised uninjured arm Rest hand of
uninjured arm on head Elevate uninjured
shoulder Adjust humerus between vertebral
column and sternum Expose on gentle breathing if
patient can Co-operate other wise suspend
respiration

• Central Ray
• Perpendicular
• Center Point
• Through the thorax to surgical neck
• Structures shown
• Lateral view of the proximal half of humerus
• and glenohumeral joint visualized through the
  thorax

• Inferosuperior Axial

Patient position Supine with shoulder raised
about 2 inches From tabletop by placing support
under arm an shoulder Part position Abduct
arm 90 degrees if possible Rotate head towards
opposite side Place vertical cassette as close
to neck And support with sand bags Suspend
respiration during exposure Central Ray 20-30
degrees medially
Center Point Horizontally to axilla

• Structures shown
• Lateral view of the proximal humerus in relation
  to the scapulohumeral cavity
