Case study involving a 16yr old football player who injured his shoulder reaching for a fumble 3 days prior to this study. His arm was abducted above his head, and then pulled behind him. The father in this case refused an MRI as a prior shoulder injury had an MRI and resulted in a negative study. Thought his son was fine when the Radiograph showed no fracture and the patient could still raise his arm above his head. The Doctor then ordered the ultrasound appealing to the lower cost, readily available due to the fact we are located next door to his office. The father of the football player agreed to this, and we were all glad he did.

Bicep tendon resting in the footprint of the Subscapularis Tendon region
Scanning a little more anterior shows a Bicep Groove filled with unorganized tissue.
Subscapularis image shows retraction with anechoic fluid in place of the insertion to the Lesser Tuberocity.
Further evaluation of the Lesser Tuberocity reveals an avulsion.
Power doppler shows hyperemia to the traumatic site of the Bicep Groove
Superior Subscapularis image shows more anechoic fluid filling the tear site
Long axis of the Bicep over the Anterior Humeral Head, just lateral to the Coracoid Process. Saggital oblique Body plane as the Biceps makes its way to the superior Labrum.
.
This image shows an ill-defined Rotator Cuff Interval as the dislocated Bicep no longer splits the Supraspinatus and Torn Subscapularis tendons. Some Subscapularis tendon fibers are now sliding superiorly.
Seemingly normal Supraspinatus...when the probe is moved slightly distal.....
Slight movement of the probe distal reveals subtle tearing anterior bursal surface
Posterior Glenoid Labrum neutral view, arm resting over abdomen with the elbow bent at 90 deg.
Arm bent at 90, externally rotated slowly shows anechoic fluid benieth the Infraspinatus tendon, with echogenic material anterior to the posterior glenoid labrum capsule. Could be indicative of blood in joint capsule.
