Fig 4 — Humeral tunnel drilling and graft passage, right shoulder, viewed from lateral portal. (A) A Beath pin is introduced from anterolateral portal, aiming at bicipital groove. (B) The pin is drilled posteriorly until it exits at the upper part of native infraspinatus tendon insertion point. (C) A 4.5-mm rigid cannulated drill is first used to ream from anterior to posterior to create a humeral tunnel. The length of the tunnel is measured. (D) An 8-mm rigid cannulated drill is used to ream from posterior to anterior until the desired length inside the humeral tunnel. (E) A grasper is inserted along the length of the infraspinatus muscle, and the shuttling suture is pulled out of the opening of the infraspinatus fascia. (F) The free limb of semitendinosus tendon not fixed with LTT is passed from the loop of a 20-mm EndoButton (arrowhead) and works in a double fashion. (G and H) The EndoButton is passed intra-articularly from posterior to anterior, until it exits the bicipital groove. Abbreviations: BG, bicipital groove; ISP, intraspinatus; LTT, lower trapezius tendon.
