Edited by The Ultrasound Subcommittee of the European Society of Musculoskeletal Radiology (ESSR)
Highlights
Place the transducer over the posterior aspect of the glenohumeral joint with the arm in the same position described under paragraph 2 and increase the depth to include the structures of the posterior fossa within the field-of-view of the US image
The common extensor tendon is visualized on its long axis using coronal planes with the cranial edge of the probe placed on the lateral epicondyle
A knee flexion of approximately 20-30° obtained by placing a small pillow beneath the popliteal space stretches the extensor mechanism and avoids possible anisotropy related to the concave profile that the quadriceps and patellar tendons assume in full extension
Summary
Place the arm in slight internal rotation (directed towards the contralateral knee) with the elbow flexed 90°, palm up. Start by finding the long biceps tendon in between the greater and lesser tuberosities. Use short- and long- (more limited utility) axis planes to examine the biceps. Shift the probe up to examine the biceps in its intra-articular course and down to reach the myotendinous junction (level of the pectoralis major tendon).
