Dr. Prohaska –
Impingement Series
Our impingement series includes the following views:
True AP (Grasheys)
Axillary Lateral View
Supraspinatus Outlet view
30° Caudal Tilt
AP of AC Joint
All of these views are listed below with examples and a description of how to shoot them.
True AP (Grasheys)
Position: Patient erect with affected side against Bucky, turn patient 30-35 degrees
Tube: Perpendicular
Demonstrates: Glenohumeral joint space
Axillary Lateral View
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
Supraspinatus Outlet View
Position: Patient erect PA, with affected side against Bucky, turn patient 40-45 degrees
Tube: 15-20 degrees caudal with central ray at the coracoid
Demonstrates: Acromial morphology
30 Degree Caudal Tilt
Position: Patient erect or supine
Tube: 30 degrees caudal entering at coracoid
Demonstrates: Acromial morphology
AP of AC Joint
Position: Patient erect or supine
Tube: Perpendicular to AC Joint
Demonstrates: AC Joint
