First Claim
Patent Images
1. A method of surgically implanting a glenoid component into the glenoid of a patient, comprising:
- drilling an anchor hole into the glenoid of the patient,securing an anchor surface of a rasp guide into the glenoid of the patient, the rasp guide including a concave guide surface that is opposite the anchor surface and an anchor peg extending perpendicularly therefrom,oscillating a surgical rasp over the rasp guide such that the concave guide surface guides the surgical rasp to abrade bone tissue to form a cavity shaped to receive the glenoid component, andimplanting the glenoid component in the cavity,wherein oscillating the surgical rasp includes pivoting the surgical rasp along an arced path to define a concave posterior glenoid surface, andwherein securing the rasp guide into the glenoid of the patient comprises inserting the anchor peg of the rasp guide in the drilled anchor hole.

6. A method of surgically implanting a glenoid component into a glenoid of a patient, comprising:
-
inserting a guide pin into the glenoid of the patient, advancing a reamer over the guide pin, reaming the glenoid of the patient to create a reamed surface, advancing a cannulated drill over the guide pin, drilling an anchor hole into the reamed surface of the glenoid of the patient, inserting an anchor peg of a rasp guide in the drilled anchor hole to secure an anchor surface of the rasp guide into the glenoid of the patient, the rasp guide including a concave guide surface that is opposite the anchor surface and the anchor peg extends perpendicularly from the anchor surface, oscillating a surgical rasp over the rasp guide such that the concave guide surface guides the surgical rasp to abrade bone tissue to form a cavity shaped to receive the glenoid component, and implanting the glenoid component in the cavity, wherein oscillating the surgical rasp includes pivoting the surgical rasp along an arced path to define a concave posterior glenoid surface. - View Dependent Claims (7, 8, 9)
