Our instability series includes the following views:
- True AP
- Axillary Lateral View
- Stryker Notch View
- West point View
Each of these is listed below with examples and a description of how to shoot it.
True AP
- Position: Patient erect with affected side against Bucky, turn patient 30-35 degrees
- Tube: Perpendicular
- Demonstrates: Glenohumeral joint space
Axillary Lateral
- Position: Patient supine with small sponge under shoulder, humerus abducted to 90 degrees, elbow bent 90 degrees and perpendicular to table
- Tube: Central ray bisecting angle of humerus and body
- Demonstrates: Glenohumeral joint, Coracoid process pointing anteriorly, Lessor tuberosity in profile, AC joint, acromion, and end of clavicle project through, humeral head
Stryker Notch View
- Position: Erect or supine, with hand on back of head
- Tube: 10 degrees cephalic to the coracoid
- Demonstrates: Hill-Sachs defects
West point View
- Position: Prone with sponge supporting affected shoulder, abduct arm 90 degrees, bend elbow and hang forearm off the table
- Tube: Central ray is double angled – 25 degrees from horizontal and 25 degrees medially
- Demonstrates: Bony abnormalities of the glenoid rim, Instability
