CLAIMS

WHAT IS CLAIMED IS:

1. An insert component for use with a glenosphere, comprising:

an insert body including first surface, a second surface, and a third surface;

the first surface configured to engage a bone;

the second surface spaced from the first surface and cooperating with the first surface to define at least one first channel, the at least one first channel configured to receive an engagement member;

the third surface having a first surface end and a second surface end each extending from a perimeter of the first surface, a curved portion of the third surface between the first surface end and the second surface end extending into the insert body, the curved portion shaped to contact a bone engagement member; and

a cavity defined within the insert body, the cavity including a first cavity opening defined by the first surface, the cavity defining a first cavity region and a second cavity region each coextensive with a third cavity region, the first cavity region and second cavity region each having a cavity diameter greater than a diameter of a plate engagement member.

2. The insert component of claim 1, further comprising a fourth surface extending from the third surface, the fourth surface defining a second cavity opening of the cavity opposite the first cavity opening.

3. The insert component of claim 1, wherein at least one first channel defines a first channel axis parallel to a cavity axis defined by the cavity.

4. The insert component of claim 1, wherein the first surface is configured to promote bone growth.

5. The insert component of claim 1, wherein the cavity is between the third surface and the at least one channel.

6. The insert component of claim 1, wherein a first arc length along a first rim of the first surface is greater than a second arc length of the curved portion of the third surface.

7. The insert component of claim 1, further comprising at least one second channel on an opposite side of the at least one first channel from the cavity, the at least one second channel configured to receive a bone fixation member configured to secure the insert component to the bone.

8. The insert component of claim 7, wherein a first plane parallel to a first opening of the at least one first channel defined by the second surface is spaced from a second plane parallel to a second opening of the at least one second channel.

9. The insert component of claim 7, wherein the at least one second channel defines a second channel axis that is not parallel to a first channel axis defined by the at least one first channel.

10. A shoulder prosthesis system, comprising:

a plate configured to be attached to a portion of a shoulder bone, the plate including a plate body including a first plate surface and a second plate surface opposite the first plate surface, the plate including an engagement member extending from the second plate surface, the plate configured to receive a plurality of plate fixation members, the plurality of plate fixation members configured to attach the plate to the portion of the shoulder bone;

a glenosphere including a glenosphere body including a first body surface and a spherical second body surface, the first body surface including an insert engagement region and a plate engagement region, the plate engagement region configured to engage with the engagement member of the plate; and

an insert component including an insert body including a first insert surface, a second insert surface, and a third insert surface, the first insert surface configured to engage the shoulder bone, the second insert surface configured to engage with the insert engagement region of the glenosphere.

11. The shoulder prosthesis system of claim 10, wherein the second insert surface is spaced from the first insert surface and cooperates with the first insert surface to define at least one first channel, the at least one first channel configured to receive an engagement member.

12. The shoulder prosthesis system of claim 10, wherein the third insert surface includes a first surface end and a second surface end each extending from a perimeter of the first insert surface, a curved portion of the third insert surface between the first surface end and the second surface end extending into the insert body, the curved portion shaped to contact a bone engagement member associated with the plate.

13. The shoulder prosthesis system of claim 10, further comprising a cavity defined within the insert body, the cavity including a first cavity opening defined by the first insert surface, the cavity defining a first cavity region and a second cavity region each coextensive with a third cavity region, the first cavity region and second cavity region each having a cavity diameter greater than a diameter of the plate fixation member.

14. The shoulder prosthesis system of claim 10, further comprising a flange component configured to engage the first body surface of the glenosphere, the flange component including at least one flange channel configure to receive a bone fixation member for securing the flange to the shoulder bone.

15. The shoulder prosthesis system of claim 10, wherein the insert component includes at least one second channel on an opposite side of the at least one first channel from the cavity, the at least one second channel configured to receive a bone fixation member configured to secure the insert component to the bone.

16. The shoulder prosthesis system of claim 15, wherein a first distance from a first rim of the first surface where the first surface is adjacent to the third surface to a second rim of the first surface opposite the first rim and adjacent to the at least one second channel is greater than a second distance from a point of the insert engagement region where the third surface contacts the insert engagement region to a glenosphere rim at which the first body surface is adjacent to the second body surface.

17. The shoulder prosthesis system of claim 15, wherein the at least one second channel defines a second channel axis that is not parallel to a first channel axis defined by the at least one first channel.

18. The shoulder prosthesis system of claim 15, wherein a first plane parallel to a first opening of the at least one first channel defined by the second surface is spaced from a second plane parallel to a second opening of the at least one second channel.

19. The shoulder prosthesis system of claim 10, further comprising a fourth insert surface extending from the third insert surface, the fourth insert surface defining a second cavity opening of the cavity opposite the first cavity opening.

20. The shoulder prosthesis system of claim 10, wherein the cavity is between the third insert surface and the at least one channel.

21. The shoulder prosthesis system of claim 10, wherein a first arc length along a first rim of the first insert surface is greater than a second arc length of the curved portion of the third insert surface.

22. The shoulder prosthesis system of claim 10, wherein the insert component is configured to be adjacent to the first plate surface while the insert component is engaged with the insert engagement region and the plate is engaged with the plate engagement region.
