Abstract

Claims (23)

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.

2. The method of claim 1 , wherein the shoulder implant comprises a reverse shoulder implant baseplate and further comprising coupling the reverse shoulder implant baseplate to the anchor trajectory guide prior to advancing the aperture of the anchor trajectory guide over the peripheral guide pin.

3. The method of claim 1 , further comprising establishing with the patient specific glenoid guide a central guide feature near a central region of the glenoid.

4. The method of claim 3 , wherein establishing the central guide feature comprises advancing a central guide pin extending from the central region of the glenoid.

5. The method of claim 4 , further comprising

advancing a reamer with reference to one or both of the central guide pin or the peripheral guide pin to the glenoid surface; and

reaming the glenoid surface.

6. 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;

coupling a reverse shoulder implant baseplate to an anchor trajectory guide; and

advancing an aperture of an anchor trajectory guide over the peripheral guide pin to a predefined position over the glenoid.

7. The method of claim 6 , further comprising:

establishing, with the patient-specific glenoid guide, a central guide feature near a central region of the glenoid.

8. The method of claim 7 , wherein establishing the central guide feature near the central region of the glenoid includes advancing a central guide pin extending from the central region of the glenoid.

9. The method of claim 8 , further comprising:

advancing a reamer with reference to one or both of the central guide pin or the peripheral guide pin to the glenoid surface; and

reaming the glenoid surface.
