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
