Bankart lesion of the shoulder
Bankart lesion : A compression defect on the inferior articular surface of the humeral head due to impingement on the glenoid fossa during recurrent dislocations of the shoulder.
Radiographic Appearance : The Bankart’s lesion is usually seen as a small fracture or a osteophitic deposit probably due to micro fractures, there is often a corresponding Bankart’s fracture of the inferior margin of the glenoid fossa.
The lesion is visible on plain radiographs but a more detailed view can be obtained through multiplanar reconstruction using CT and MRI.
Labral Tear/Bankart Lesion seen at tips of red arrows
Fibrous Bankart lesion. An axial T1 weighted spin echo MR arthrographic image with fat saturation, at the level of the inferior glenoid labrum, demonstrates the avulsed and displaced labroligamentous complex from the anteroinferior aspect of the glenoid, with complete disruption of the scapular periosteum, which constitutes the fibrous Bankart lesion (arrow).
