Abstract

A patient-specific guide tool for guiding an object toward a glenoid face of a scapula of a patient for implantation of a shoulder prosthetic device is disclosed. The guide tool includes a guide portion that includes a guide surface. The guide surface is configured to guide movement of the object toward the glenoid face. Furthermore, the guide tool includes a patient-specific portion that is operably coupled to the glenoid portion. The patient-specific portion includes at least one patient-specific surface that is three-dimensionally contoured and that is configured to nest and closely conform to a corresponding surface of the scapula to thereby position the guide surface at a predetermined position relative to the glenoid face.

Claims (25)

1. A patient-specific guide tool for guiding an object toward a glenoid face of a scapula of a patient for implantation of a shoulder prosthetic device, the guide tool comprising:

a patient-specific glenoid portion having at least one patient-specific surface that is configured to nest and closely conform to a corresponding surface of the glenoid face to position the at least one patient-specific surface at a predetermined position relative to the glenoid face;

a first tube projecting longitudinally from the patient-specific glenoid portion opposite the at least one patient-specific surface, wherein the first tube defines a first opening that extends longitudinally along a length of the first tube from an end thereof to the patient-specific portion;

a second tube offset from the first tube and projecting longitudinally from the patent-specific glenoid portion, wherein the second tube defines a second opening that extends longitudinally along a length of the second tube from an end thereof to the patient-specific portion; and

a handle that projects from the first tube, the second tube and the patient-specific glenoid portion opposite the at least one patient-specific surface.

2. The patient-specific guide tool of claim 1 , wherein the at least one patient-specific surface is configured to nest and closely conform to a rim of the glenoid face.

3. The patient-specific guide tool of claim 1 , further comprising a second patient-specific portion that is operably coupled to the patient-specific glenoid portion, the second patient-specific portion including a second at least one patient-specific surface that is three-dimensionally contoured and configured to nest and closely conform to a corresponding surface of the scapula outside of the glenoid face.

4. The patient-specific guide tool of claim 3 , wherein the second at least one patient-specific surface is configured to nest and closely conform to a corresponding anterior surface of an acromion of the scapula.

5. The patient-specific guide tool of claim 3 , wherein the second at least one patient-specific surface is configured to nest and closely conform to a corresponding inferior surface of an acromion of the scapula.

6. The patient-specific guide tool of claim 3 , wherein the second at least one patient-specific surface is configured to nest and closely conform to a corresponding posterior surface of an acromion of the scapula.

7. The patient-specific guide tool of claim 1 , wherein the patient-specific glenoid portion includes a notch to provide exposure to the glenoid face.

8. A patient-specific guide for guiding an object toward a glenoid face of a scapula of a patient for implantation of a prosthetic device, the guide tool comprising:

a patient-specific portion having at least one patient-specific surface that is configured to nest and closely conform to a corresponding surface of the glenoid face to position the at least one patient-specific surface at a predetermined position relative to the glenoid face; and

a first tube and a second tube projecting longitudinally from the patient-specific portion opposite the at least one patient-specific surface, wherein the first tube defines a first opening that extends longitudinally along a length of the first tube from an end thereof to the patient-specific portion, the second tube defining a second opening that extends longitudinally along a length of the second tube from an end thereof to the patient-specific portion, wherein the first tube is offset from and angled relative to the second tube;

wherein the at least one patient-specific surface is configured to position the first and second openings in a predetermined manner relative to the glenoid face;

wherein when the at least one patient-specific surface is mounted on the glenoid face, the first opening is oriented for use in a normal shoulder implantation procedure and the second opening is oriented for use in a reverse shoulder implantation procedure.

9. The guide of claim 8 , wherein the at least one patient-specific surface is configured to engage and nest with an anterior rim of the glenoid face.

10. The guide of claim 8 , wherein the at least one patient-specific surface is configured to nest with one or more of a superior, inferior and posterior portion of a rim of the glenoid face.

11. The guide of claim 8 , wherein the first opening and the second opening allow access for at least one of a drill bit and referencing object to the glenoid face through the patient-specific portion, and wherein the first tube is configured to receive at least one of the drill bit and the referencing object used for the implantation of a normal shoulder prosthetic device.

12. The guide of claim 8 , wherein the first opening and the second opening allow access for at least one of a drill bit and referencing object to the glenoid face through the patient-specific portion, and wherein the second tube is configured to receive at least one of the drill bit and the referencing object used for the implantation of a reverse shoulder prosthetic device.

13. The guide of claim 8 , further comprising a second patient-specific portion that is operably coupled to the patient-specific portion, the second patient-specific portion including a second at least one patient-specific surface that is three-dimensionally contoured and configured to nest and closely conform to a corresponding surface of the scapula outside of the glenoid face.

14. The guide of claim 13 , wherein the second at least one patient-specific surface is configured to nest and closely conform to a corresponding anterior surface of an acromion of the scapula.

15. The guide of claim 13 , wherein the second at least one patient-specific surface is configured to nest and closely conform to a corresponding inferior surface of an acromion of the scapula.

16. The guide of claim 13 , wherein the second at least one patient-specific surface is configured to nest and closely conform to a corresponding posterior surface of an acromion of the scapula.

17. The guide of claim 8 , wherein the patient-specific portion includes a notch to provide exposure to the glenoid face.
