Reciprocating rasps for use in an orthopaedic surgical procedure
First Claim
Patent Images
1. A method of surgically implanting a glenoid component into a glenoid of a patient, comprising:
- inserting a guide pin into bone tissue of the glenoid of the patient,advancing a reciprocating surgical rasp over the guide pin along a longitudinal axis, wherein the surgical rasp includes a cutting head having a cutting surface formed on a first side of the longitudinal axis and a depth stop formed on a second side of the longitudinal axis opposite the first side, such that the cutting head is asymmetrical,reciprocating the surgical rasp so as to abrade only a portion of the bone tissue of the glenoid to form a stepped surface to receive the glenoid component, andimplanting the glenoid component across the stepped surface.

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.

9. 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 reciprocating surgical rasp having a shaft and a cutting head attached to one end of the shaft over the guide pin along a longitudinal axis such that the guide pin extends through an opening formed in the cutting head of the surgical rasp and further extends through a guide ring spaced from the cutting head along the longitudinal axis, wherein the cutting head has a cutting surface formed only on a first side of the longitudinal axis such that the cutting head is asymmetrical, 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. - View Dependent Claims (10, 11, 12, 13)

14. 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 reciprocating surgical rasp over the guide pin along a longitudinal axis, wherein the surgical rasp includes a cutting head having a cutting surface formed on a first side of the longitudinal axis and a depth stop formed on a second side of the longitudinal axis opposite the first side such that the cutting head is asymmetrical and the depth stop is spaced from the cutting surface along the longitudinal axis, reciprocating the surgical rasp such that the cutting surface of the surgical rasp abrades bone tissue to form a cavity shaped to receive the glenoid component; and implanting the glenoid component in the cavity; wherein reciprocating the surgical rasp so as to abrade bone tissue comprises advancing the reciprocating surgical rasp toward the glenoid of the patient until the depth stop of the surgical rasp contacts the glenoid of the patient. - View Dependent Claims (15, 16, 17)
