Abstract

A joint prosthesis system, specifically a shoulder prosthesis, for shoulder replacement, revision and repair. The implants provide fixation into the best bone available to a surgeon. The implants are used in a superior-inferior and anterior-posterior construct forming a type of cross or X-shape. The implants allow for interchangeability of the articulating component as well as rotational orientation. The systems will allow for augments to accommodate bone loss. The implants may allow for additional security using screws or anchors inserted into the scapula.

First claim

The invention claimed is:

1. A joint prosthesis configured to couple to one of an articulating component and a glenosphere, each of the articulating component and the glenosphere including a post, the post including at least one of a protrusive ring and a cutout ring, the joint prosthesis comprising:
a vertical component, wherein the vertical component comprises a body comprising a bore extending at least partially through the body in a longitudinal direction and at least one vertical component arm extending from the body; and
a horizontal component, wherein the horizontal component comprises a wall defining a hole, an engagement ring positioned on the wall, the engagement ring extending at least one of toward a center of the hole and away from the center of the hole, the engagement ring being configured to engage the at least one of the protrusive ring and the cutout ring on the post of the one of the articulating component and the glenosphere, and at least one horizontal component arm extending from the wall;
wherein the vertical component and the horizontal component are configured to engage at the body of the vertical component and the wall of the hole of the horizontal component.

2. The joint prosthesis of claim 1 , wherein the body is a central ring, the bore is a central bore and the hole is a central hole.

3. The joint prosthesis of claim 1 , wherein the vertical component and horizontal component form a cruciate.

4. The joint prosthesis of claim 1 , wherein the horizontal component is configured to be rotatable in relation to the vertical component about the central ring.

5. The joint prosthesis of claim 1 , wherein the at least one vertical component arm further comprises a first lateral bore separate from the central bore.

6. The joint prosthesis of claim 5 , wherein the at least one vertical component arm comprises a second vertical component arm wherein the second vertical component arm comprises a second lateral bore separate from the first lateral bore and separate from the central bore.

7. The joint prosthesis of claim 6 , wherein the first and second lateral bores are configured to receive screws.

8. The joint prosthesis of claim 6 , wherein the at least one horizontal component arm further comprises a third lateral bore separate from the central hole.

9. The joint prosthesis of claim 8 , wherein the at least one horizontal component arm comprises a second horizontal component arm wherein the second horizontal component arm comprises a fourth lateral bore separate from the third lateral bore and separate from the central hole.

10. The joint prosthesis of claim 9 , wherein the third and fourth lateral bores are configured to receive screws.

11. The joint prosthesis of claim 1 , wherein the horizontal component further comprises at least one keel extending substantially parallel to the central hole, wherein the at least one keel provides rotational stops of the horizontal member against the vertical member.

12. The joint prosthesis of claim 1 , wherein the wall of the central hole comprises notches configured to engage the post of the one of the articulating component and the glenosphere, wherein the notches are configured to allow rotational orientation of the one of the articulating component and the glenosphere and to prevent rotation of the one of the articulating component and the glenosphere.

13. The joint prosthesis of claim 3 , wherein the central hole comprises a polygonal opening configured to receive a polygon component, wherein the polygonal opening and polygon component are configured, in combination, to allow rotational orientation of one of the articulating component and the glenosphere and to prevent rotation of one of the articulating component and the glenosphere.

14. The joint prosthesis of claim 13 , wherein the polygon component is hexagonal.

15. A joint prosthesis configured to couple to an articulating component, the articulating component including an articulating surface, a bone-facing surface spaced apart and facing an opposite direction from the articulating surface, a post extending from the bone-facing surface, and at least one partial augment extending from the bone-facing surface, the joint prosthesis comprising:
a superior-inferior component, wherein the superior-inferior component comprises a central ring comprising a central bore and at least one superior-inferior component arm extending from the central ring;
an anterior-posterior component configured to be coupled to the superior-inferior component, wherein the anterior-posterior component comprises a wall defining a central hole and at least one augment extending from the wall, the at least one augment including an articulating-facing side and a bone-facing side, the articulating-facing side including pockets configure to receive the partial augment of the articulating component.

16. The joint prosthesis of claim 15 wherein the superior-inferior component and the anterior-posterior component are configured to engage at the central ring of the superior-inferior component and the wall of the central hole of the anterior-posterior component.

17. The joint prosthesis of claim 15 , wherein the at least one superior-inferior component arm further comprises a first lateral bore separate from the central bore.

18. The joint prosthesis of claim 17 , wherein the at least one superior-inferior component arm comprises a second superior-inferior component arm wherein the second superior-inferior component arm comprises a second lateral bore separate from the first lateral bore and separate from the central bore.

19. The joint prosthesis of claim 18 , wherein the first and second lateral bores are configured to receive screws.

20. The joint prosthesis of claim 15 , wherein the at least one augment comprises a first hole separate from the central hole.

21. The joint prosthesis of claim 15 , wherein the wall of the central hole comprises notches configured to engage the post of the articulating component, wherein the notches are configured to allow rotational orientation of the articulating component and to prevent rotation of the articulating component.

22. The joint prosthesis of claim 15 , wherein the wall of the central hole further comprises an engagement ring positioned on the wall, the engagement ring configured to engage the post of the articulating component.

23. A joint prosthesis configured to couple to one of an articulating component and a glenosphere, each of the articulating component and the glenosphere including a post, the post including notches, the joint prosthesis comprising:
a superior-inferior component, wherein the superior-inferior component comprising a central ring comprising a central bore and at least one superior-inferior component arm extending from the central ring; and
a cylindrical component comprising a wall defining a central hole, wherein the central hole includes notches at a proximal end of the central hole, the notches being configured to engage the notches on the post of one of the articulating component and the glenosphere;
wherein at least a portion of the cylindrical component fits within the central ring of the superior-inferior component.

24. The joint prosthesis of claim 23 , wherein the at least one superior-inferior component arm further comprises a first lateral bore separate from the central bore.

25. The joint prosthesis of claim 24 , wherein the at least one superior-inferior component
