3. Fig 2
The posterior bone block is delivered inside the glenohumeral joint through a cannula and fixed by 2 suture anchors; the arthroscopic view shows that the graft is lying flush to the articular surface.

4. Fig 3
Arthroscopic views of a right shoulder (seen from anterior portal) showing posterior Bankart repair with small suture anchors allowing reconstruction of a solid posterior bumper and complete coverage of the bone block, which becomes extra-articular.

5. Fig 4
Early CT images (at 2 weeks) showing correct bone graft positioning: in the vertical plane, the graft is subequatorial, whereas in the horizontal plane, it is flush or slightly overhanging laterally.

6. Fig 5
CT images showing bone graft healing and remodeling with time in the same patient. The 3-dimensional CT scan image of the initial posterior bone graft at 1 month of follow-up (left), 3-dimensional CT scan image at 20 months' follow-up (middle), and axial cut image (right) show healing and late remodeling of the bone graft with recreation of a pear-shaped glenoid.
