Normal Shoulder Ultrasound

Biceps Tendon• Palm up and resting on the patient’s leg

• Transducer placed on the anterior shoulder • find the best sonographic window with slight external/internal

rotation

• dynamically evaluate (external/internal rotation) for subluxation or dislocation

• angle transducer as appropriate to avoid anisotropy

Subscapularis Tendon• Palm up and arm externally rotated

• Transducer placed on the anterior shoulder

• find the best sonographic window with slight external/internal rotation

• dynamically evaluate (external/internal rotation) for tears and impingement

• angle transducer as appropriate to avoid anisotropy

Supraspinatus Tendon• hand placed in back pocket with palm facing in

• transducer placed on the anterior shoulder

• scan anterior to posterior from biceps interval to infraspinatus tendon

• dynamically evaluate (external/internal rotation) for tears

• dynamically evaluate (abduction/adduction) for impingement

• angle transducer as appropriate to avoid anisotropy
