Page #'s: 1:167,46

Positioning:
  • Pt. Upright, if possible
  • Humerus over midline of Grid
  • Arm slightly abducted
  • Hand supinated, =Arm in same plane

CR Entrance & Angle:
  • _|_ mid Humerus; Top of film 1 ½'' above humeral head
  •

Collimation:
  • Both Proximal & Distal Joints

Respiration:
  • Suspend

Best to Determine:
  • Humeral Head & Greater Tubercle in profile (Laterally)

Eval Criteria:
  • NR-Epicondyles

CR Entrance & Angle:
  • _|_ mid Humerus; Top of film 1 ½'' above humeral head
  •

Collimation:
  • Both Proximal & Distal Joints

Respiration:
  • Suspend

Best to Determine:

Trauma Lateral
IR Size:
SID:
Page #'s: 1:171

Positioning:
  • When a known or suspected fracture exists, position the patient in the recumbent or lateral recumbent position, place the IR close to the axilla, and center the humerus to the midline of the IR.
  • Unless contraindicated, flex the elbow, turn the thumb surface of the hand up, and rest the humerus on a suitable support

CR Entrance & Angle:
  • Horizontal & _|_ to the mid-portion of the humerus & center of the IR
  •

Collimation:
  •

Eval Criteria:
  • SI-epicondyles
  • Distal humerus

Transthoracic
IR Size: 14x17 LW
SID: 40''
Page #'s: 1:192

Positioning:
  • Pt. Upright, if possible
  • Affected side against bucky
  • Place uninjured arm on he as much as possible which drops the injured side separating shoulders from SI
  • Do not attempt to rotate injured arm

CR Entrance & Angle:
  • _|_ MCP and to surgical neck area of affected humerus
  • If pt can't elevate uninjured arm angle 10-15° cephalad

Collimation:
  •

Anatomy to IR:
  •

Eval Criteria:
  • Proximal humerus
  • Unaffected clavicle and humerus projected above the shoulder closest to the IR
