General things you need to know about The clavicle…. •Cassette Size: 10 x 12 Crosswise •Measures 14 •Shield: On Lap! •Put marker in light field. •Deep breathe and hold The Views….. • AP •AP Axial •Can be done erect or supine Woo hoo! Not to many!!! The AP… • Placement: Remove all metallic objects. •Place patient with back against the IR. •Patient looking straight so not to impose chin. •Center clavicle to center of IR. •Central Ray: Perpendicular to mid- clavicle •40 SID The Ap… Contd • Seen on Radiograph: The entire clavicle including both the ac joint and the sc joint. The mid-clavicle will superimpose the superior scapula angle. Medial clavicle will be next to the vertebral column. Lateral end aligns with the acromion. The AP axial view • Placement: Same as the AP. No movement of Patient. •Central Ray: Perpendicular to mid-clavicle •Angle 15- 30 Degrees cephalad. The AP axial view.. contd. • Seen on Radiograph: entire clavicle including both joints. The medial end superimposes the first and second rib. The lateral end is superior to acromion No imposition of superior scapula angle Clavicle bows slightly upward. Most of the clavicle will be free of imposition. General things you need to know about The scapula…. •Cassette Size: 10 x 12 lengthwise •Shield: On Lap! •Put marker in light field. •Breathing technique for AP The Views….. • AP •lateral •Can be done erect or supine Woo hoo! Not to many!!! The AP… • Placement: Remove all metallic objects. •Place patient with back against the IR. •Center scapula to center of IR. •IR should be 2 inches above shoulder and 2 inches medial form rib boarder. •Abduct arm 90 degrees. •Supinate the hand (moves scapula lateral to clear more thoracic structures) Central Ray Perpendicular to the mid-scapula area 2 inches below the coracoid process or level of axilla and 2 inches medially. 40 SID The Ap… Contd • Seen on Radiograph: The entire scapula The lateral portion of scapula free from imposition. Medial portion will be seen through the thoracic structures. The Lateral 10 x 12 lengthwise Hold breathe Measures 15 The Lateral Placement: face patient toward cassette in and anterior oblique position with affected shoulder against the IR Have patient reach across the chest and grab opposite shoulder. (body) less rotation Have patient drop arm and place behind back. ( acromion and coracoid) Feel scapula and rotate scapula until a true lateral position is reached. About 30-45degree for scapula and 45-60 for patient. The lateral… Contd • Seen on Radiograph: The entire scapula in a true lateral position The vertebral and lateral borders of body superimposed. Body free of imposition by ribs and in profile The scapula should form a Y. The acromion and coracoid as the arms and the scapula body as the leg.
