See the list below:

  • Standard radiographic studies are used to rule out glenohumeral/acromioclavicular arthritis and Os Acromiale.

    • Anteroposterior view of the glenohumeral joint

    • Internal rotation view of the humerus with a 20° upward angulation to show the acromioclavicular joint

    • Axillary view - Most useful to rule out subtle signs of instability (eg, glenoid avulsion, Hill-Sachs lesion) and to visualize the presence of an os acromiale

    • Stryker notch view - Potential os acromiale is easily visualized and assessed when viewed through the humeral head

    • Supraspinatus outlet view - Most useful to assess the supraspinatus outlet space (If < 7 mm, the patient is more at risk for impingement syndrome.) and helps assess morphology of the acromion (A hooked acromion is more at risk for impingement.)
