All seven specimens were dissected at the end of the two procedures to verify the graft stabilization anteriorly and posteriorly with the four buttons using a grasper, to assess the covering of the tendon on the graft and its position on the glenoid edge, and to identify any interference between the two glenoid tunnels and the anchor for the subscapularis tenodesis; the contact surface between the anterior part of the glenoid and the bone graft was measured using a ruler. Finally, we investigated the neurovascular structures in relation to the gleno-humeral joint.
