case_images: CT imagingat the time of injury. Axial image of CT shows a bony Bankart lesion at the anteroinferior part of glenoid articular surface (a). Size of the bony fragment was 17 mm x 27 mm and its width was 41% of the glenoid length on the 3-dimensional CT (b).

case_images: Computed tomography (CT) revealed a bony Bankart lesion at the anteroinferior part of glenoid articular surface (Figure 1(a)). Size of the bony fragment was 17 mm x 27 mm and its width was 41% of the glenoid length on the 3-dimensional CT (3D CT) evaluation (Figure 1(b)).
case_images: Arthroscopic view from the posterior portal. The bony fragment (F) could be easily reduced drawing up by grasper through the anterior portal (a). The bony Bankart lesion was fixed by DTJ screw after confirmation of flat reduction at the articular surface (b). G: glenoid.

case_images: The bony fragment could be easily reduced drawing up by grasper through the anterior portal (Figure 2(a)) and the ruptured capsulolabrum at the superior part was repaired with conventional suture anchor technique. A 1.2 mm guide wire was inserted to the bony fragment using a cannula and the bony Bankart lesion was fixed by 24 mm DTJ screw after confirmation of flat reduction at the articular surface (Figure 2(b)).
case_images: CT imaging at the time of revision. Axial image of CT showed union of the bony Bankart fragment, however, the screw end appeared to protrude intraarticular space (a). 3-dimensional CT (b).

case_images: CT showed union of the bony Bankart fragment, however, the screw end appeared to protrude intraarticular space (Figure 3).
case_images: Second-look arthroscopy reveals the smooth articular surface at the bony Bankart lesion, and the screw end could not be found as existed under the articular cartilage.
