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 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, andimplanting the glenoid component in the cavity,wherein the surgical rasp comprises a shaft having a base of a cutting head secured to one end of the shaft and the shaft has an elongated bore formed therein, wherein a perimeter of the base comprises substantially parallel superior and inferior sides and anterior and posterior sides joining the superior and inferior sides, andwherein advancing the surgical rasp over the guide pin comprises advancing the surgical rasp such that the guide pin is received into the elongated bore.

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.

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 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, wherein implanting the glenoid component in the cavity comprises implanting a vault glenoid component in the cavity, the vault glenoid component comprising a wedge-shaped body, wherein reciprocating the surgical rasp so as to abrade bone tissue comprises reciprocating the surgical rasp so as to abrade bone tissue to form a wedge-shaped cavity to receive the wedge-shaped body of the vault glenoid component, wherein the cavity has an opening comprising substantially parallel superior and inferior sides and anterior and posterior sides joining the superior and inferior sides. - View Dependent Claims (7, 8, 9)

10. 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, 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, wherein reciprocating the surgical rasp so as to abrade bone tissue comprises advancing a first reciprocating surgical rasp toward the glenoid of the patient to abrade bone tissue to form a cavity of a first size, removing the first reciprocating surgical rasp and replacing it with a second, larger reciprocating surgical rasp, and advancing the second reciprocating surgical rasp toward the glenoid of the patient to abrade bone tissue to form a cavity of a second, larger size, wherein each cavity has an opening comprising substantially parallel superior and inferior sides and anterior and posterior sides joining the superior and inferior sides. - View Dependent Claims (11)
