Bankart lesion with concurrent Hill-Sachs lesion
Updates to Case Attributes
Anterior dislocation is the most common type of shoulder dislocation, when it is accompanied by an anterior glenoid labrum tear is called a Bankart lesion.
The humeral head usually dislocates in an anteroinferior direction.
Bankart lesions result from high-energy trauma or sports injuries(either acute injuries or overuse injuries from repetitive arm motions).
On radiography, the Hill-Sachs lesion is best demonstrated on an AP radiograph with the arm in internal rotation.
On cross-sectional imaging, a Hill-Sachs lesion should be above the level of the coracoid, as there is a normal concavity of the humeral head located about the level of the coracoid that can be confused with a chronic Hill-Sachs lesion.

Updates to Study Attributes
There is depression in the posterolateral aspect of the humeral head with significant surrounding edemaoedema suggesting a Hill-Sachs lesion associated with a fragmented, avulsed anteroinferior labroligamentous complex, features representing Bankart lesion with concurrent Hill-Sachs lesion.
No definite bony Bankart.
Moderate joint effusion.
Minimal fluid in the subscapular recess.
