1. A shoulder surgery method, comprising:
placing a patient specific glenoid guide having a patient specific bone contact surface on a surface of a scapula of a patient such that the patient specific bone contact surface is in contact with a corresponding bone surface;
advancing a peripheral guide pin into the scapula near a peripheral region of a glenoid of the patient with reference to the patient specific glenoid guide,
advancing an aperture of an anchor trajectory guide over the peripheral guide pin to a predefined position over the glenoid;
forming a peripheral anchor channel in the scapula from the glenoid surface toward an opposing cortical bone region; and
securing a shoulder implant on the glenoid surface by advancing a peripheral anchor into the peripheral anchor channel formed through the anchor trajectory guide.
