1. 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 ;
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, and wherein: the first and second stabilization members comprise a first edge, a second edge, and a longitudinal axis extending from the base portion and along a mid-point between the first edge and the second edge, and the first and second stabilization members are asymmetrical about the longitudinal axis.
