Patient Positioning
Patient seated on a revolving stool, arm in external rotation. Elbow flexed (90°), palm up.
Probe Positioning
Move the probe medially from the insertion of the subscapularis tendon at the lesser tuberosity to the coracoid process. Use dynamic scanning (passive external and internal rotation with hanging arm) to examine the entire tendon and its myotendinous junction.
Note: use dynamic scanning (internal and external rotation of the arm). Check the tendon for integrity or structural changes and look carefully for bursal effusion (near coracoid process, too)
