(A) The anteroinferior portal is created using a surgical blade through the mid-subscapularis tendon. (B) An 8-mm cannula (Arthrex) (P) is inserted aiming toward the defect area and serves as the main working portal. (G, glenoid; H, humeral head; Sc, subscapularis tendon.)

(A) The template is placed at the anteroinferior glenoid defect using the suture railroad (arrow). (B) Drilling and tapping are performed using a 3.5-mm cannulated screw system (Synthes) at 2 caudad holes (arrow).

6. Fig 5
Sizing, drilling, and tapping guided by the same template are performed before the graft harvest. The width of the iliac graft is designed to be 2 to 3 mm wider than the template (black arrow) with the length long enough to cover 2 holes of the template (white arrow), and the height is approximately 10 mm. The harvested graft measures 10 × 20 × 10 mm (inset).

7. Fig 6
The iliac graft with the suture railroad in the upper hole (white arrow) is inserted through the anterosuperior portal using a slit cannula (red arrow) modified from a 10-mL plastic syringe (Terumo). The black arrow indicates the anteroinferior portal.

(A) Slit cannula modified from a 10-mL plastic syringe (Terumo). (B) Folding the leading part (arrow) allows easier insertion.

9. Fig 8
The iliac bone graft is fixed by a 3.5-mm cannulated screw system (Synthes). An arthroscopic view from the posterior portal shows stable fixation with the concave inner table of the iliac graft staying flush with the articular glenoid surface (inset). (BG, iliac bone graft; G, glenoid; H, humeral head.)
