Abstract

A method for reconstructing a joint according to an exemplary aspect of the present disclosure includes, among other things, fixating at least one suture inside a joint space, retrieving the at least one suture from inside the joint space, passing the at least one suture through a graft at a location external to the joint space, shuttling the graft into the joint space and fixating the graft using the at least one suture.

First claim

What is claimed is:

1. A method for reconstructing a joint, comprising:
inserting a first suture anchor at a posterior position of a glenoid of the joint;
inserting a second suture anchor at an anterior position of the glenoid;
inserting a third suture anchor at a posterior position of a humerus of the joint;
inserting a fourth suture anchor at an anterior position of the humerus;
measuring a first distance between the first suture anchor and the second suture anchor;
measuring a second distance between the third suture anchor and the fourth suture anchor;
measuring a third distance between the second suture anchor and the fourth suture anchor;
measuring a fourth distance between the first suture anchor and the third suture anchor;
subsequent to the measuring, sizing a dermal graft to a size indicated by the first distance, the second distance, the third distance, and the fourth distance;
cutting the dermal graft to the size indicated by the first distance, the second distance, the third distance, and the fourth distance;
retrieving a first suture from the first suture anchor, a second suture from the second suture anchor, a third suture from the third suture anchor, and a fourth suture from the fourth suture anchor;
passing the first suture, the second suture, the third suture, and the fourth suture through the sized dermal graft with the dermal graft positioned externally from the joint;
shuttling the sized dermal graft through a cannula and into the joint;
fixating the sized dermal graft to the glenoid using the first suture and the second suture; and
fixating the sized dermal graft to the humerus using the third suture and the fourth suture.

2. The method as recited in claim 1 , wherein the dermal graft is knotlessly fixated to the humerus.

3. The method as recited in claim 1 , wherein sizing the dermal graft includes enlarging the dermal graft around its periphery prior to cutting the dermal graft.

4. The method as recited in claim 3 , wherein the dermal graft is enlarged by at least 5 millimeters about the periphery.

5. The method as recited in claim 1 , comprising, prior to cutting the dermal graft, marking a location on the dermal graft where each of the first suture, the second suture, the third suture, and the fourth suture will pass through the dermal graft.

6. The method as recited in claim 5 , comprising creating a hole at each mark on the dermal graft to assist in passing the first suture, the second suture, the third suture, and the fourth suture through the dermal graft.
