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.
Mild calcific tendinitis of the infraspinatus tendon with intratendinous calcifications closed to the greater tuberosity, no intraarticular or bursal effusion
