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.

Claims2

Dependent claims

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, 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.

Dependencies are inferred from the claim text.
