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: Check the tendon for its integrity or structural changes, look for bursal effusion and use as less pressure as possible with the transducer.
