Abstract

A suture construction and method for forming a suture construction is disclosed. The construction utilizes a suture having an enlarged central body portion defining a longitudinal passage. First and second ends of the suture are passed through first and second apertures associated with the longitudinal passage to form a pair of loops. Portions of the suture lay parallel to each other within the suture. Application of tension onto the suture construction causes constriction of the longitudinal passage, thus preventing relative motions of the captured portions of the suture.

Claims

1. An apparatus for use in surgical implantation, comprising:

an adjustable flexible member construct having a body extending between first and second ends, the body defining first and second longitudinal passage portions, the first end passing into and through the first longitudinal passage portion to place the first end outside of the first longitudinal passage portion and form a first adjustable loop, the second end passing into and through the second longitudinal passage portion to place the second end outside of the second longitudinal passage portion and form a second adjustable loop wherein the flexible member is a suture formed from braided or woven fibers, and wherein said passing of the first end into and through the first longitudinal passage portion includes the first end extending through a first aperture in the body, along the first longitudinal passage portion, and out a second aperture in the body to place the first end outside of the first longitudinal passage portion and form the first adjustable loop, and wherein said passing of the second end into and through the second longitudinal passage portion includes the second end extending through a third aperture in the body, along the second longitudinal passage portion, and out a fourth aperture in the body to place the second end outside of the second longitudinal passage portion and form the second adjustable loop, the first, second, third and fourth apertures being formed between the braided or woven fibers of the suture; and

a fastener coupled to the flexible member construct.

2. The apparatus of claim 1, wherein the fastener is a threaded bone fastener.

3. The apparatus of claim 1, wherein the first, second, third and fourth apertures are separate apertures.

4. The apparatus of claim 1, wherein the fastener includes at least one bore centrally positioned in the fastener, the flexible member construct being received in the at least one bore.

5. The apparatus of claim 1, wherein the fastener is coupled to the flexible member construct adjacent the first and second longitudinal passage portions.

6. The apparatus of claim 5, further comprising a second fastener slidably coupled to the first and second adjustable loops.

7. The apparatus of claim 1, wherein the first and second adjustable loops include first and second self-locking adjustable loops configured to self-lock under tension to maintain a reduced size of the adjustable loops under tension.

8. The apparatus of claim 1, wherein the first and second longitudinal passage portions are spaced apart from each other.

9. The apparatus of claim 8, wherein, with the first end passing into and through the first longitudinal passage portion to place the first end outside of the first longitudinal passage portion and with the second end passing into and through the second longitudinal passage portion to place the second end outside of the second longitudinal passage portion, the first end can be pulled through the first longitudinal passage portion to decrease a size of the first adjustable loop without decreasing a size of the second adjustable loop and the second end can be pulled through the second longitudinal passage portion to decrease the size of the second adjustable loop without decreasing the size of the first adjustable loop.

10. An apparatus for use in surgical implantation, comprising:

a flexible member having a body extending between first and second ends and defining a longitudinally extending passage extending from the first end to the second end, the first end extending into a first aperture in the body along a first passage portion of the longitudinally extending passage and out a second aperture in the body to form a first adjustable loop, the second end extending into a third aperture in the body along a second passage portion in the longitudinally extending passage and out a fourth aperture in the body to form a second adjustable loop; and

a first fixation member coupled to the flexible member.

11. The apparatus of claim 10, further comprising a second fixation member coupled to the flexible member.

12. The apparatus of claim 11, wherein the first fixation member is coupled adjacent to the first and second passage portions and the second fixation member is coupled to the first and second adjustable loops.

13. The apparatus of claim 11, wherein the first fixation member is a bone engaging member and the second fixation member is a soft tissue fixation member.

14. The apparatus of claim 10, wherein the first fixation member is coupled adjacent to the first and second passage portions, the first fixation member has a first profile which allows insertion of the first fixation member through a bone tunnel and a second profile which allows engagement with a positive locking surface upon rotation of the first fixation member.

15. The apparatus of claim 10, wherein the flexible member is a suture formed from braided or woven fibers, and wherein the first, second, third and fourth apertures are formed between the braided or woven fibers of the suture.

16. The apparatus of claim 15, wherein the first, second, third and fourth apertures are separate apertures.

17. The apparatus of claim 16, wherein the first and second passage portions are spaced apart from each other.

18. The apparatus of claim 10, wherein the first and second adjustable loops include first and second self-locking adjustable loops configured to self-lock under tension to maintain a reduced size of the adjustable loops under tension.

19. A system for use in surgical implantation, further comprising:

an adjustable flexible member construct having a body extending from a first end to a second end and defining a longitudinally extending passage in the body extending from the first end to the second end, the adjustable flexible member construct including a first adjustable loop and a second adjustable loop formed from the body, at least a portion of the first adjustable loop passing through a first portion of the longitudinally extending passage and at least a portion of the second adjustable loop passing through a second portion of the longitudinally extending passage; and

a first fixation device coupled to the adjustable flexible member construct wherein the first fixation device is coupled adjacent to the first and second portions of the longitudinally extending passage, wherein the first fixation device has a first profile which is configured to allow insertion of the first fixation device through a bone tunnel and a second profile which is configured to allow engagement with a positive locking surface upon rotation from the first profile to the second profile.

20. The apparatus of claim 19, further comprising a second fixation device extending from the first and second adjustable loops.

21. The apparatus of claim 20, wherein the first fixation device is a bone engaging device and the second fixation device is a soft tissue engaging device.

22. The apparatus of claim 19, wherein the body of the adjustable flexible member construct is formed of a suture having braided fibers.

23. The apparatus of claim 22, wherein the body of the suture defines first, second, third, and fourth apertures formed between the braided fibers of the suture and the first portion is defined between the first and second apertures and the second portion is defined between the third and fourth apertures.

24. The apparatus of claim 23, wherein the first and second portions are spaced apart from each other.

25. The apparatus of claim 24, wherein the first, second, third and fourth apertures are separate apertures.

26. The apparatus of claim 19, wherein the first end of the body is configured to be pulled to adjust a length of the first adjustable loop and the second end of the body is configured to be pulled to adjust a length of the second adjustable loop.

27. The apparatus of claim 19 further comprising a ligament graft coupled to the first and second adjustable loops.
