Abstract

Method of stabilizing a sternum with a fastening member defining a plurality of cleats. In the method, the fastening member may be disposed on a sternum having a discontinuity, with the fastening member spanning the discontinuity and the cleats contacting the sternum. The fastening member may be arranged with a wire or cable such that the wire or cable extends twice through the fastening member and forms a loop around a portion of the sternum. The fastening member may be crimped to secure both ends of the loop to the fastening member.

Claims (23)

1. A method of stabilizing a sternum with a fastening member defining a plurality of cleats, the method comprising:

arranging the fastening member with a wire or cable such that the wire or cable extends twice through the fastening member and forms a loop around at least a portion of the sternum; and

crimping the fastening member to produce tight engagement between the fastening member and the wire or cable, such that both ends of the loop are secured to the fastening member;

wherein the crimped fastening member spans a discontinuity of the sternum and contacts the sternum with the plurality of cleats.

2. The method of claim 1 , wherein the discontinuity forms a pair of sternal segments, and wherein at least one of the cleats of the crimped fastening member is in contact with each of the sternal segments.

3. The method of claim 2 , wherein a different pair of the cleats of the crimped fastening member is in contact with each of the sternal segments.

4. The method of claim 1 , wherein the steps of arranging and crimping are each performed twice such that a pair of loops are secured to the fastening member.

5. The method of claim 4 , wherein the pair of loops are provided by a first wire or cable and a second wire or cable.

6. The method of claim 4 , wherein the pair of loops are spaced from each other along the sternum.

7. The method of claim 4 , wherein the steps of arranging and crimping are each performed at least three times such that at least three loops are secured to the fastening member.

8. The method of claim 1 , wherein the fastening member includes a plate body having an inner surface region that faces the sternum after the step of crimping, and wherein the cleats taper away from the inner surface region to form prongs.

9. The method of claim 1 , wherein the step of crimping secures both ends of the loop to the fastening member at the same time.

10. The method of claim 1 , wherein the fastening member has a plurality of tabs from which the cleats project.

11. The method of claim 1 , further comprising a step of tensioning the wire or cable with a tool before the step of crimping.

12. The method of claim 11 , wherein the tool holds the wire or cable in a tensioned configuration while the fastening member is crimped.

13. The method of claim 1 , further comprising a step of cutting through the wire or cable after the step of crimping.

14. The method of claim 13 , wherein the step of cutting through the wire or cable cuts the loop.

15. The method of claim 1 , wherein a spanning member of the fastening member spans the discontinuity, and wherein the spanning member and the cleats are formed collectively as one piece.

16. The method of claim 1 , wherein the steps of arranging and crimping are performed with a plurality of fastening members and a plurality of wires or cables to form a plurality of loops arranged along the sternum from one another.

17. The method of claim 1 , wherein the wire or cable extends through the fastening member parallel to an axis, and wherein the step of crimping includes a step of applying compressive force to the fastening member orthogonal to the axis.

18. The method of claim 17 , wherein the step of applying compressive force includes a step of contacting a projection of the fastening member with a compression tool.

19. The method of claim 18 , wherein the step of contacting a projection includes a step of contacting a pair of projections of the fastening member with a compression tool.

20. The method of claim 1 , further comprising a step of sectioning the sternum longitudinally to create a pair of sternal segments before the step of disposing.
