Claim 15:
16. A method of preparing a glenoid of a shoulder joint of a patient for a shoulder arthroplasty procedure, the method comprising:
positioning a first contact surface of a base portion of a cutting guide into contact with a first surface of the glenoid that forms a cavity, the first contact surface being patient-specific and shaped to match the first surface of the glenoid, wherein the base portion of the cutting guide has a guide hole extending therethrough;
positioning a first stabilization member in contact with a first surface of a scapula of the patient, the first stabilization member extending from the base portion of the cutting guide and having a second contact surface being patient-specific and shaped to match the first surface of the scapula;
positioning a second stabilization member in contact with a second surface of the scapula, the second stabilization member extending from the base portion of the cutting guide and having a third contact surface being patient-specific and shaped to match the second surface of the scapula,
wherein while the first contact surface of the base portion is in contact with the first surface of the glenoid, a coracoid process of the patient is positioned between the first stabilization member and the second stabilization member;
inserting a guide pin through the guide hole and into the first surface of the glenoid;
removing the base portion of the cutting guide from the glenoid while the guide pin remains in the first surface of the glenoid;
drilling a guide recess in the first surface of the glenoid, the drilling being guided by the guide pin; and
inserting a screw or peg of a glenoid prosthesis into the guide recess in the first surface of the glenoid.
