	AP Humerus Rotate body toward affected side as needed to bring shoulder and proximal humerus in contact with cassette. •Align humerus with long axis of IR, unless diagonal placement is needed to include both shoulder and elbow joints. •Extend hand and forearm as far as patient can tolerate. •Abduct arm slightly and gently supinate hand so that epicondyles of elbow are equidistant from IRCR perpendicular to IR, directed to midpoint of humerus •Minimum SID of 40 inches Structures Shown: • AP projection of the entire humerus, including the shoulder and elbow joints, is visible. Position: • Long axis of humerus should be aligned with long axis of IR. • True AP projection is evidenced at proximal humerus by the following: Greater tubercle is seen in profile laterally; humeral head is partially seen in profile medially, with minimal superimposition of the glenoid cavity. • Distal humerus: Lateral and medial epicondyles both are visualized in profile. Collimation and CR: • Collimation borders are visible at the skin margins along the length of the humerus, with minimal collimation at both ends to ensure that essential joint anatomy is included. • CR and center of the collimation field should be to the approximate midpoint of the humerus. Exposure Criteria: • Optimal density and contrast with no motion visualize sharp cortical margins and clear, bony trabecular markings at both proximal and distal portions of the humerus Aadaadd
	Lateral Humerus projections: •Position patient erect or supine as for lateromedial or mediolateral projection. •Lateromedial: Position patient erect with back to IR and elbow partially flexed, with body rotated toward affected side as needed to bring humerus and shoulder in contact with cassette. Internally rotate arm as needed for lateral position; epicondyles are perpendicular to IR. •Mediolateral: Face patient toward IR (Fig. 6-27) and oblique as needed (20° to 30° from PA) to allow close contact of humerus with IR; flex elbow 90° as shown. •Adjust cassette height so that shoulders and elbow joints are equidistant from ends of cassette. •CR perpendicular to IR, centered to midpoint of humerus •Minimum SID of 40 inches Structures Shown: • A lateral projection of the entire humerus, including elbow and shoulder joints, is visible. Position: • True lateral projection is evidenced by the following: Epicondyles are directly superimposed; lesser tubercle is shown in profile medially, partially superimposed by lower portion of glenoid cavity. Collimation and CR: •Collimation borders should be visible at the skin margins along the length of the humerus, with minimal collimation at both ends to ensure that essential joint anatomy is included. • CR and center of collimation field should be to the approximate midpoint of the humerus. Exposure Criteria: • Optimal density and contrast with no motion visualize clear, sharp bony trabecular markings of entire humerus.
