Abstract

A method for securing a strand to a fixation member for arthroscopic fixation, wherein the fixation member includes a channel on an exterior surface and an aperture therethrough. The method includes passing a strand having first and second ends through a flexible sleeve, passing the sleeve through the aperture of the fixation member in a first direction, tensioning the strand, and pulling the sleeve in a second direction different than the first direction to secure the sleeve to the fixation member without tying the strand on the fixation member.

Claims

1. A method for securing a flexible strand to at least one fixation member for a surgical procedure, the method comprising:

passing a flexible sleeve through a hole in the at least one fixation member in a first configuration;

positioning the at least one fixation member, having the flexible strand passing through the fixation member from a first side to a second side of the fixation member and through the flexible sleeve on the first side of the fixation member, into a bore formed into tissue; and

tensioning the flexible strand on the second side of the fixation member to deform the flexible sleeve to a second configuration to prevent the flexible sleeve from passing through the hole and cause the fixation member to rotate in the bore.

2. The method of claim 1, further comprising forming the bore in the tissue, where the tissue is bone.

3. The method of claim 1, wherein tensioning the flexible strand includes tensioning first and second ends of the flexible strand on the second side of the fixation member to deform the flexible sleeve on the first side of the fixation member and cause the fixation member to rotate in the bore such that a tissue engaging surface of the fixation member engages the bore.

4. The method of claim 1, wherein the fixation member is disk-shaped and defines a hole passing through the disc-shaped fixation member.

5. The method of claim 1, wherein positioning at least the one fixation member into the bore formed into tissue includes moving the fixation member in a first direction with the flexible sleeve in a first configuration and wherein tensioning the flexible strand includes moving the flexible strand in a second opposite direction to deform the flexible sleeve to a second configuration.

6. A method for securing a flexible strand to at least one fixation member for a surgical procedure, the method comprising:

forming a bore in tissue and forming a bore in bone;

positioning a flexible sleeve attached to a flexible strand and the fixation member into the bore; and

tensioning the flexible strand to deform the flexible sleeve and cause the fixation member to rotate in the bore;

wherein the fixation member includes a disk-shaped member having a bone-engaging surface about the disk-shaped member, wherein upon rotating the fixation member in the bore, the bone-engaging surface engages the bone to secure the flexible strand relative to the bone.

7. The method of claim 6, wherein the fixation member is a disk-shaped fixation member defining a hole passing therethrough, wherein the method further includes passing the flexible sleeve through the hole in the disk-shaped fixation member in a first configuration and wherein tensioning the flexible strand deforms the flexible sleeve to a second configuration.

8. The method of claim 6, wherein the flexible sleeve is on a first side of the fixation member and an end of the flexible strand is on an opposite side of the fixation member, wherein upon tensioning the flexible strand on the second side of the fixation member, the flexible sleeve on the first side of the fixation member deforms.

9. The method of claim 6, wherein the fixation member defines a first hole and a second hole passing through the fixation member from a first side of the fixation member to a second side of the fixation member, wherein the flexible sleeve and ends of the flexible strand are on the first side of the fixation member upon tensioning the flexible strand.

10. The method of claim 6, wherein the flexible sleeve has first and second ends and first and second ends of the flexible strand exit the sleeve from corresponding first and second openings of the sleeve.

11. The method of claim 10, wherein the corresponding first and second openings of the sleeve are at the first and second ends of the sleeve.

12. A method for securing a flexible strand to at least one fixation member, the method comprising:

providing a disk-shaped fixation member having a tissue-engaging surface and defining at least one hole extending through the disk-shaped fixation member from a first side to a second side of the disk-shaped fixation member;

passing at least a portion of the flexible strand having first and second ends through at least a portion of a longitudinal bore of a flexible sleeve such that the first and second ends of the flexible strand are outside the flexible sleeve;

positioning the flexible strand through the hole in the disk-shaped fixation member such that the flexible sleeve is positioned on the first side of the disk-shaped fixation member and at least the first end of the flexible strand extends from the disk-shaped fixation member; and

positioning the flexible sleeve attached to the flexible strand and the disk-shaped fixation member into a bore formed in bone.

13. The method of claim 12, wherein the at least first end of the flexible strand extends from the second side of the disk-shaped fixation member.

14. The method of claim 12, wherein the disk-shaped fixation member defines a second hole extending through the disk-shaped fixation member from the first side to the second side of the disk-shaped fixation member, the method further comprising passing the flexible strand through the second hole in the disk-shaped fixation member.

15. The method of claim 12, further comprising tensioning the flexible strand to deform the flexible sleeve and cause the disk-shaped fixation member to rotate in the bore.

16. The method of claim 15, wherein positioning the flexible sleeve on the first side of the fixation member includes deforming the flexible sleeve into a first configuration and passing through the hole, wherein tensioning the flexible strand includes tensioning the flexible strand to change the sleeve to a second configuration that cannot re-enter the hole.
