Abstract

Various joint replacements are disclosed herein, as are methods of use thereof. The joint replacements can have a flexible band or multiple flexible bands that can link together a first part of the joint replacement and a second part of the joint replacement. The flexible band or bands can be tensioned to establish proper tension in the patient's joint. In certain circumstances, the joint replacement can be a shoulder joint replacement.

First claim

What is claimed is:

1. A joint replacement system comprising: a glenoid component including a concave articulating surface and a peripheral surface; a humeral component including a convex head and a peripheral surface; and a first flexible band attached to the peripheral surfaces of the glenoid component and the humeral component, the first flexible band linking the glenoid component to the humeral component and providing tension therebetween; further comprising a first opening on the peripheral surface of the glenoid component, wherein a portion of the first flexible band is inserted through the first opening to attach the first flexible band to the peripheral surface of the glenoid component, and a first opening on the peripheral surface of the humeral component, wherein a portion of the first flexible band is inserted through the first opening to attach the first flexible band to the peripheral surface of the humeral component.

2. The joint replacement system of claim 1 , further comprising a plurality of flexible bands attached to the peripheral surfaces of the glenoid component and the humeral component, the plurality of flexible bands linking the glenoid component to the humeral component and providing tension therebetween.

3. The joint replacement system of claim 1 , wherein the first flexible band is composed of suture.

4. The joint replacement system of claim 1 , further comprising a second flexible band attached to the peripheral surfaces of the glenoid component and the humeral component, the second flexible band linking the glenoid component to the humeral component and providing tension therebetween, where the second flexible band is tensioned tighter than the first flexible band.

5. The joint replacement system of claim 1 , further comprising a mesh linking the glenoid component to the humeral component.

6. The joint replacement system of claim 5 , wherein the first flexible band is part of the mesh.

7. The joint replacement system of claim 1 , wherein the first flexible band has a self-locking structure.

8. A method of implanting a joint replacement comprising: attaching a glenoid component to a patient's glenoid; attaching a humeral component to a patient's humerus; inserting a portion of a first flexible band to the peripheral surface of the glenoid component, inserting a portion of the first flexible band through a first opening on a peripheral surface of the humeral component to attach the first flexible band to the peripheral surface of the humeral component; and tensioning the first flexible band to keep the patient's humeral component in registration with the glenoid component.

9. The method of claim 8 , further comprising linking the glenoid component to the humeral component using a plurality of flexible bands.

10. The method of claim 9 , wherein the plurality of flexible bands comprise a mesh that links the glenoid component to the humeral component.

11. The method of claim 8 , further comprising linking the glenoid component to the humeral component using a second flexible band, and tensioning the second flexible band to a greater degree of tension than the first flexible band.

12. The method of claim 8 , further comprising locking the first flexible band after tensioning the first flexible band.

13. The method of claim 12 , wherein the first flexible band comprises a self-locking mechanism, and the method further comprises self-locking the first flexible band after tensioning the first flexible band.

14. The method of claim 13 , wherein first flexible band is composed of suture, and the self-locking mechanism comprises a self-constricting passage formed in the suture.

15. The method of claim 14 , further comprising passing a portion of the first flexible band through the self-constricting passage to form a loop of suture.

16. The method of claim 15 , further comprising pulling on a free end of the first flexible band to decrease a size of the loop of suture, thereby causing the self-constricting passage to constrict about the portion of the first flexible band and lock the first flexible band within the self-constricting passage.
