Abstract

An orthopedic prosthesis ( 20, 100 ) including an implant body ( 22, 24, 26, 122 ) defining a number of suture anchor attachment locations ( 30, 120 ), and a plurality of suture anchors ( 40 ) each including one or more suture (S) extending from an anchor portion ( 42 ) that is engaged with a select one of the suture anchor attachment locations ( 30, 120 ) to selectively attach a corresponding one of the suture anchors ( 40 ) to the implant body ( 22, 24, 26, 122 ). A method of using the orthopedic prosthesis ( 20, 100 ) is also provided.

First claim

What is claimed is:

1. An orthopedic prosthesis, comprising:
a shoulder prosthesis including a stem portion extending along a longitudinal axis, a head portion, and a body portion extending between said stem portion and said head portion, wherein said shoulder prosthesis includes a plurality of suture anchor attachment locations, each of said suture anchor attachment locations comprising a first engagement element; and
a plurality of suture anchors, each of said suture anchors including one or more sutures extending from an anchor portion, said anchor portion comprising a second engagement element for engagement with said first engagement element of a select one of said suture anchor attachment locations to selectively attach a corresponding one of said suture anchors to said shoulder prosthesis,
wherein the body portion includes a pair of arcuate recesses that define a fin extending in a direction parallel to the longitudinal axis and structured to abut a greater tuberosity fragment and a lesser tuberosity fragment of a patient's shoulder for reduction of said greater and lesser tuberosity fragments to a proper anatomic position.

2. The orthopedic prosthesis of claim 1 wherein said suture anchor attachment locations each comprise an opening extending at least partially through a thickness of said shoulder prosthesis; and wherein said anchor portion of said corresponding one of said suture anchors is positionable within said opening and is retainable in said opening by engagement of said first engagement element with said second engagement element.

3. The orthopedic prosthesis of claim 2 wherein said anchor portion includes an outer end wall positioned substantially flush with or recessed below an outer surface of said shoulder prosthesis when said anchor portion is positioned within said opening.

4. The orthopedic prosthesis of claim 2 wherein said anchor portion includes an outer sidewall engageable with a corresponding inner sidewall of said opening.

5. The orthopedic prosthesis of claim 4 wherein each of said outer sidewall of said anchor portion and said inner sidewall of said opening has either a conical shape or a circular cylindrical shape.

6. The orthopedic prosthesis of claim 4 wherein one of said outer sidewall of said anchor portion and said inner sidewall of said opening defines a recess; wherein another of said outer sidewall of said anchor portion and said inner sidewall of said opening defines a projection; and wherein said projection is positionable within said recess to provide said engagement of said first engagement element with said second engagement element.

7. The orthopedic prosthesis of claim 6 wherein said recess comprises an annular groove; and wherein said projection comprises a ring or clip positionable within said annular groove to provide said engagement of said first engagement element with said second engagement element.

8. The orthopedic prosthesis of claim 6 wherein said projection is formed of an elastic material to facilitate positioning of said projection within said recess.

9. The orthopedic prosthesis of claim 4 wherein one of said outer sidewall of said anchor portion and said inner sidewall of said opening defines a first threaded portion; and wherein another of said outer sidewall of said anchor portion and said inner sidewall of said opening defines a second threaded portion configured to threadingly engage with said first threaded portion to provide said engagement of said first engagement element with said second engagement element.

10. The orthopedic prosthesis of claim 1 wherein one of said first and second engagement elements comprises a recess; wherein another of said first and second engagement elements comprises a projection; and wherein said projection is positionable within said recess to provide said engagement of said first engagement element with said second engagement element.

11. The orthopedic prosthesis of claim 10 wherein said recess comprises an annular groove, and wherein said projection comprises a ring or clip positionable within said annular groove to provide said engagement of said first engagement element with said second engagement element.

12. The orthopedic prosthesis of claim 10 wherein said projection is formed of an elastic material to facilitate positioning of said projection within said recess.

13. The orthopedic prosthesis of claim 1 wherein one of said first and second engagement elements comprises a first threaded portion; wherein another of said first and second engagement elements comprises a second threaded portion; and wherein said first threaded portion is configured to threadingly engage with said second threaded portion to provide said engagement of said first engagement element with said second engagement element.

14. The orthopedic prosthesis of claim 1 wherein said first and second engagement elements are configured to engage with one another by a friction fit.

15. The orthopedic prosthesis of claim 1 wherein said suture anchor attachment locations each comprise a stem extending from an outer surface of said shoulder prosthesis; wherein said anchor portion of said corresponding one of said suture anchors comprises an opening; and wherein said stem of said suture anchor attachment location is positionable within said opening in said anchor portion and is retainable in said opening by said engagement of said first engagement element with said second engagement element.

16. The orthopedic prosthesis of claim 1 wherein each of said suture anchors includes a plurality of sutures extending from said anchor portion.

17. The orthopedic prosthesis of claim 1 wherein said plurality of suture anchors includes:
a first suture anchor including a plurality of sutures having a first color-coding; and
a second suture anchor including a plurality of sutures having a second color-coding different from said first color-coding.

18. The orthopedic prosthesis of claim 17 wherein said first and second color-codings are anatomy based; and wherein said first color-coding associated with said plurality of sutures of said first suture anchor corresponds to a first bone region; and wherein said second color-coding associated with said plurality of sutures of said second suture anchor corresponds to a second bone region.

19. The orthopedic prosthesis of claim 1 wherein each individual suture anchor of said plurality of suture anchors includes sutures that are provided with a unique color-coding corresponding to a particular bone region or bone fracture.

20. The orthopedic prosthesis of claim 1 wherein said body portion includes at least one of said suture anchor attachment locations.

21. The orthopedic prosthesis of claim 20 wherein said head portion has an underside surface facing said body portion, said underside surface including at least one of said suture anchor attachment locations.

22. The orthopedic prosthesis of claim 1 wherein the anchor portion of at least one of the plurality of suture anchors comprises a rigid body separate from the corresponding one or more sutures of the at least one of the plurality of suture anchors; and
wherein the rigid body is pre-operatively secured to the corresponding one or more sutures prior to attachment of the anchor portion to the corresponding suture anchor attachment location.

23. The orthopedic prosthesis of claim 1 wherein the body portion includes a plurality of teeth positioned opposite said fin and structured to secure the one or more
