System and method for repairing articular surfaces
A total joint replacement system comprising a first and a second implant system. The first implant system includes a first implant having a first load bearing surface based on a first removed portion of an articular surface of a patient's first bone, and a first anchor having a first threaded region configured to be secured into the first bone, wherein the first anchor is configured to be secured to the first implant. The second implant system includes a second implant having a second load bearing surface based on a second removed portion of an articular surface of a patient's second bone, and a second anchor having a second threaded region configured to be secured into the second bone, wherein the second anchor is configured to be secured to the second implant.
1. A joint replacement system for repairing a first articular surface and a second articular surface corresponding to a humerus and a oppositely arranged glenoid cavity, respectively, said system comprising:
a humerus implant system comprising:
a first implant having a first load bearing surface; and
a first anchor having a first threaded region configured to be secured into said humerus, wherein said first anchor is configured to be secured to said first implant; and
a glenoid cavity implant system comprising:
a second implant having a hemispherical load bearing surface configured to articulate against said first load bearing surface; and
a second anchor having a second threaded region configured to be secured into said glenoid cavity, wherein said second anchor is configured to be secured to said second implant; and
a support plate, said support plate configured to be secured to said second anchor and further configured to be secured to said second implant.
2. The joint replacement system of claim 1 , wherein said second implant and said second anchor include a first and a second fixation element, respectively.
3. The joint replacement system of claim 2 , wherein said first and said second fixation elements are configured to form tapered connection therebetween.
4. The joint replacement system of claim 3 , wherein said first and said second fixation elements comprise a tapered cavity and a tapered protrusion configured to form a tapered connection therebetween.
5. The joint replacement system of claim 2 , wherein said second anchor includes a longitudinal passageway.
6. The joint replacement system of claim 5 , further comprising a guide wire configured to be at least partially received within said longitudinal passageway of said second anchor.
7. The joint replacement system of claim 2 , wherein said first and said second fixation elements are configured to form a snap-fit connection therebetween.
8. The joint replacement system of claim 7 , wherein said second anchor defines an implant cavity configured to receive at least a portion of a bone facing surface of said second implant.
9. The joint replacement system of claim 8 , wherein at least a portion of a periphery of said cavity includes said second fixation element and wherein at least a portion of said bone facing surface includes said first fixation element.
10. The joint replacement system of claim 1 , wherein said first load bearing surface is configured to replace substantially the entire first articular surface.
11. The joint replacement system of claim 1 , wherein said second load bearing surface is configured to replace a portion of said second articular surface.
12. The joint replacement system of claim 1 , wherein said first load bearing surface has a contour based on a plurality of overlapping excision sites.
13. The joint replacement system of claim 1 , wherein said first load bearing surface has a contour defining a socket.
14. The joint replacement system of claim 1 , wherein said support plate includes a first fixation element configured to be coupled to a second fixation element of said first anchor.
15. The joint replacement system of claim 14 , wherein said first and said second fixation elements are configured to form tapered connection therebetween.
16. The joint replacement system of claim 14 , wherein said first and said second fixation elements are configured to form a snap-fit connection therebetween.
17. The joint replacement system of claim 1 , wherein said support plate includes a first fixation element configured to be coupled to a second fixation element of said second implant.
18. The joint replacement system of claim 17 , wherein said first and said second fixation elements are configured to form tapered connection therebetween.
19. The joint replacement system of claim 17 , wherein said first and said second fixation elements are configured to form a snap-fit connection therebetween.
20. The joint replacement system of claim 1 , wherein said support plate further includes at least one aperture configured to receive a fastener configured to secure said support plate into said humerus.
21. The joint replacement system of claim 1 , wherein said second load bearing surface has a contour based on a portion of said second articular surface.
