  1. Humerus - AP
    • Positioning: Patient is supine or upright facing the x-ray tube. Upper limb is slightly abducted, epicondyles are parallel to IR and hand is supine. Place IR 1 1/2 above the humeral head. 
    • Demonstrates: Fractures, bone cyst, neoplasms, and dislocations. Entire humerus and both the elbow joint and shoulder joint. 
    • C/R: Perpendicular to the mid humerus. Center the C/R to the IR. 
    • IR: 14x17in (35x43cm) lengthwise
    • Grid: Yes
    • Comments: Shoulder and arm abnormalities are extremely painful; therefore, an upright position should be used whenever possible. 
    • Respiration is suspended.
  2. Humerus - Lateral
    • Positioning: Patient is supine or upright. For supine patient, rotate forearm medially to place epicondyles perpendicular to IR. For upright patient, internally rotate arm, flex elbow 90 degrees, and place patient's anterior hand on the hip. The epicondyles are perpendicular to IR for upright patient.
    • Demonstrates: Same as AP,
    • SID: Same as AP, 40 inches
    • C/R: Same as AP, Perpendicular to the mid humerus. Center the C/R to the IR. 
    • IR: 14x17in (35x43cm) lengthwise
    • Collimation: At least 8x17'''
    • Grid: Yes
    • Comment: Respiration is suspended. If the patient has a possible fracture and the arm cannot be rotated for a lateral humerus, a Transthoracic Lateral projection should be performed. This projection will demonstrate a lateral image of the shoulder and proximal humerus, as well anterior/posterior fracture displacement of the upper 2/3 of the humerus.
  3. Shoulder - AP External
    • Positioning: The hand is supine and epincondyles are parallel with IR. 
    • Demonstrates: The shoulder in different rotations demonstrates fractures, dislocations, arthritis, bursitis, calcific deposits (neutral rotation), and some tendons.
    • The shoulder areas that must appear on the film: superior scapula, lateral half of the clavicle, and proximal humerus.
    • SID: 40 inches
    • C/R: Perpendicular to 1" inferior to the caracoid process. Center the C/R to the IR. 
    • IR: 10x12in (24x30cm) crosswise. 
    • Grid: Optional
    • Comments: Suspend respiration. Be aware that shoulder injuries are extremely painful and may have to be done erect.
  4. Shoulder - AP Neutral
    • Positioning: Rotate the arm internally and rest back of hand on the hip. The epicondyles are perpendicular to IR. 
    • Demonstrates: Same as AP External, Neutral, and
  5. Shoulder - AP Internal
    • Positioning: Rotate the arm internally and rest back of hand on the hip. The epicondyles are perpendicular to IR. 
    • Demonstrates: Same as AP External, Neutral, and
