ABSTRACT
The shoulder and scapula can be radiographically evaluated at the same time. Therefore, a study to rule out fracture of the shoulder may not demonstrate clavicle or acromioclavicular joint pathology as well as dedicated views. All views of the clavicle or shoulder should be taken erect; this will provide some weight-bearing effect and generally less discomfort for the patient. The patient should be turned toward the shoulder of interest until the scapula is parallel to the film. The external rotation shoulder views should have the humerus epicondyle parallel to the film. The internal rotation view will have the epicondyle perpendicular to the film, or the humerus in a lateral position. The internal and external rotation views are routinely taken on nontraumatic injury shoulder studies.
