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.
