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.

Claims

1. A method of surgically implanting an acetabular component into an acetabulum of a patient, comprising:

inserting an acetabular trial instrument into the acetabulum of the patient,

aligning a reciprocating surgical rasp with the acetabular trial instrument, wherein the reciprocating surgical rasp includes a cutting head with (1) a curved cutting surface and (2) a first alignment guide devoid of cutting teeth, wherein the first alignment guide of the surgical rasp is aligned with a second complementary alignment guide formed in the acetabular trial instrument and the aligning of the first alignment guide and the second complementary alignment guide occurs while the trial instrument is within the acetabulum of the patient,

reciprocating the surgical rasp, while the acetabular trial instrument is positioned in the acetabulum, so as to abrade bone tissue to form a cavity shaped to receive the acetabular component, and

implanting the acetabular component in the cavity.

2. The method of claim 1, wherein the first alignment guide is a groove and the second complementary alignment guide is a tongue.

3. The method of claim 1, wherein reciprocating the surgical rasp comprises operating a reciprocating power tool to reciprocate the surgical rasp.

4. The method of claim 1, wherein reciprocating the surgical rasp so as to abrade bone tissue comprises:

advancing a first reciprocating surgical rasp toward the acetabulum 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, larger reciprocating surgical rasp toward the acetabulum of the patient to abrade bone tissue to form a cavity of a second, larger size.

5. The method of claim 1, further comprising reaming the acetabulum of the patient to create a concave surface prior to inserting the acetabular trial instrument into the acetabulum of the patient.

6. The method of claim 1, wherein:

implanting the acetabular component in the cavity comprises implanting an augmented acetabular component in the cavity, and

reciprocating the surgical rasp so as to abrade bone tissue to form the cavity comprises reciprocating the surgical rasp so as to abrade bone tissue to form a cavity shaped to receive the augmented acetabular component.

7. The method of claim 1, wherein:

aligning the surgical rasp with the acetabular trial instrument comprises positioning a non-cutting surface of the surgical rasp into contact with the acetabular trial instrument inserted into the acetabulum of the patient, and

reciprocating the surgical rasp comprises reciprocating the surgical rasp while the non-cutting surface of the surgical rasp is in contact with the acetabular trial instrument.

8. The method of claim 7, wherein positioning the non-cutting surface of the surgical rasp into contact with the acetabular trial instrument comprises positioning an anterior non-cutting surface of the surgical rasp and a posterior non-cutting surface of the surgical rasp into contact with the acetabular trial instrument inserted in the acetabulum of the patient.

9. The method of claim 1, wherein aligning the surgical rasp with the acetabular trial instrument comprises:

aligning a spacer block with the acetabular trial instrument, and

aligning the surgical rasp with the spacer block.

10. The method of claim 9, wherein:

aligning the spacer block with the acetabular trial instrument comprises advancing the spacer block such that a tongue formed in the second complementary alignment guide of the acetabular trial instrument is received into a groove formed in the spacer block, and

aligning the surgical rasp with the spacer block comprises advancing the surgical rasp such that a tongue formed in the spacer block is received into a groove formed in the first alignment guide of the surgical rasp.

11. A method of surgically implanting an acetabular component into an acetabulum of a patient, comprising:

inserting an acetabular trial instrument into the acetabulum of the patient,

aligning a reciprocating surgical rasp with the acetabular trial instrument, wherein the aligning step includes aligning a first alignment guide formed within a first flat surface of the surgical rasp with a second alignment guide formed within a second flat surface of the acetabular trial instrument and the aligning occurs while the acetabular trial instrument is within the acetabulum of the patient,

reciprocating the surgical rasp, while the acetabular trial instrument is positioned in the acetabulum, so as to abrade bone tissue to form a cavity shaped to receive the acetabular component, and

implanting the acetabular component in the cavity.

12. The method of claim 11, wherein the first alignment guide is a groove and the second alignment guide is a tongue.

13. The method of claim 11, wherein reciprocating the surgical rasp comprises operating a reciprocating power tool to reciprocate the surgical rasp.

14. The method of claim 11, wherein reciprocating the surgical rasp so as to abrade bone tissue comprises:

advancing a first reciprocating surgical rasp toward the acetabulum 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, larger reciprocating surgical rasp toward the acetabulum of the patient to abrade bone tissue to form a cavity of a second, larger size.

15. The method of claim 11, further comprising reaming the acetabulum of the patient to create a concave surface prior to inserting the acetabular trial instrument into the acetabulum of the patient.

16. The method of claim 11, wherein:

implanting the acetabular component in the cavity comprises implanting an augmented acetabular component in the cavity, and

reciprocating the surgical rasp so as to abrade bone tissue to form the cavity comprises reciprocating the surgical rasp so as to abrade bone tissue to form a cavity shaped to receive the augmented acetabular component.

17. The method of claim 11, wherein:

the first flat surface of the surgical rasp is a non-cutting surface,

aligning the surgical rasp with the acetabular trial instrument comprises positioning the non-cutting surface of the surgical rasp into contact with the second flat surface of the acetabular trial instrument inserted into the acetabulum of the patient, and

reciprocating the surgical rasp comprises reciprocating the surgical rasp while the non-cutting surface of the surgical rasp is in contact with the second flat surface of the acetabular trial instrument.
