[CPPD] Infraspinatus labral calcifications

Patient Positioning

Patient seated on a revolving stool, arm in slight internal rotation. Elbow flexed (90°), palm up (hand can be placed on the thigh).

Probe Positioning

The posterior glenohumeral joint is found by placing the transducer medially from the humeral head on a horizontal plane (long axis of infraspinatus tendon). Check the posterior labrum capsular complex (effusion? calcifications? lesion?) and the infraspinatus and teres minor tendons during external and internal rotation.
