Abstract
Reciprocating rasps for the surgical preparation of the bone prior to the implantation of a glenoid or acetabular component with complex geometry are disclosed. Surgical methods for the use of such reciprocating rasps are also disclosed. Some of the methods include inserting a guide pin into the glenoid of the patient, advancing a reciprocating surgical rasp over the guide pin, reciprocating the surgical rasp so as to abrade bone tissue to form a cavity shaped to receive the glenoid component, and implanting the glenoid component in the cavity.

2. A reciprocating rasp surgical instrument for use in the surgical preparation of a glenoid of a patient prior to implantation of a glenoid prosthesis, the reciprocating rasp surgical instrument comprising:
-
a shaft having a first end configured to be secured in a chuck of a reciprocating tool, and a cutting head coupled to a second end of the shaft, the cutting head having (i) a wedge-shaped body extending between a base and an end, the base of the wedge-shaped body including a pair of planar edges and a pair of curved edges joining the planar edges, and (ii) a cutting surface extending from the base to the end of the wedge-shaped body and including a plurality of cutting teeth arranged in a geometry that corresponds with a geometry of the glenoid prosthesis. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10)

11. A surgical instrument system comprising:
-
a guide pin configured to be inserted into a glenoid of a patient, a surgical rasp configured to be advanced along the guide pin, the surgical rasp having a cutting head with (i) a wedge-shaped body extending between a base and an end, the base of the wedge-shaped body and (ii) a cutting surface formed on the wedge-shaped body and including a plurality of cutting teeth arranged in a geometry to surgically prepare a wedge-shaped vault in the glenoid of the patient, and a glenoid prosthesis having a body sized and shaped to receive a humeral head, a keel extending from the body and having a wedge-shape that corresponds to the wedge-shaped body of the surgical rasp. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
