The acromion and coracoid processes of the scapula are best demonstrated on the lateral projection of the scapula when the patient's arm is positioned with the forearm behind the back with 90 degrees' flexion of the elbow. The blade of the scapula, upper portion of the humerus, and greater tubercle may also be visualized on this projection, but they are not as well demonstrated as the acromion and coracoid processes.
