Patient-specific cutting guide for the shoulder

A method of making a patient-specific cutting guide for guiding a surgical instrument for resecting a portion of a humerus of a patient comprising:

• obtaining image data associated with at least a portion of the humerus of the patient;
• generating a model of the humerus of the patient from the image data;
• creating the patient-specific cutting guide having a base portion including a contact surface shaped to substantially match an outer surface of a neck portion of the humerus, at least one proximal stabilization member extending medially from the base portion and having a contact surface shaped to substantially match an outer surface of a head portion of the humerus, and at least one distal stabilization member includes a contact surface shaped to substantially match an outer surface of a shaft portion of the humerus;
• and
• providing the patient-specific cutting guide with a guide slot for directing movement of the surgical instrument,
• wherein creating the contact surfaces of the base portion, at least one proximal stabilization member, and at least one distal stabilization member includes shaping the contact surfaces based on the model of the humerus of the patient generated from the image data.

A method of making a patient-specific cutting guide for guiding a surgical instrument for resecting a portion of a glenoid cavity of a patient comprising:

• obtaining image data associated with at least a portion of a glenoid of the patient;
• generating a model of the glenoid of the patient from the image data;
• creating the patient-specific cutting guide having a base portion with a contact surface shaped to substantially match at least a portion of the glenoid cavity, the base portion having a guide hole extending therethrough, the guide hole having an axis coaxial with an axis of rotation, and at least one stabilization member extending outwardly from the base portion and having a contact surface shaped to substantially match an outer surface of a portion of a scapula of the patient;
• and
• providing the patient-specific cutting guide with a guide hole for directing movement of the surgical instrument,
• wherein creating the contact surfaces of the base portion and the at least one stabilization member includes shaping the contact surfaces based on the model of the glenoid of the patient generated from the image data.
