Bony Bankart on radiograph (a), CT (b, c), and MRI (d) in several patients. a Crescentic bone fragment at the inferomedial aspect of the glenohumeral (GH) joint space (white arrow) in this young man who was post anterior dislocation and reduction. This is a medially displaced bony Bankart fracture. Axial (b) and sagittal CT (c) with typical appearance of anterior glenoid fracture (white arrows). d Oblique coronal proton density fat-saturated MR shows inferior glenoid marrow edema (arrowhead) and bony Bankart fracture (arrow). Joint effusion is present, with distention of the inferior GH capsule (black arrowhead). Long head biceps tendon is surrounded by fluid (black arrow), which tracks in the biceps sheath—and extension of the articular space
