Abstract

Assemblies for securing fractured bone are provided. The assembly includes a first fixation element, a second fixation element, and an adjustable flexible member construct. The first fixation element having a male or a female sleeve is secured within a first portion of the fractured bone. The second fixation element having the other of the male or female sleeve telescopically received within the one of the male or female sleeve is secured within a second portion of the fractured bone. The adjustable flexible member construct extends between the first and second fixation elements and has at least one adjustable loop coupled to the first fixation element and the second fixation element and a pair of adjusting ends extending through an opening in the first fixation element. The pair of adjusting ends can be pulled to reduce a diameter of the adjustable loop and to compress fragments of the fractured bone.

Claims

1. An assembly for securing a fractured bone comprising:

a first fixation element configured to be secured within a first portion of the fractured bone, the first fixation element having one of a male or a female sleeve extending from the first fixation element;

a second fixation element configured to be secured within a second portion of the fractured bone, the second fixation element having the other of the male or female sleeve extending from the second fixation element and telescopically engaging the other of the male or female sleeve of the first fixation element; and

an adjustable flexible member construct extending between the first and second fixation elements, the adjustable flexible member construct having at least one adjustable loop independently coupled to the first fixation element and the second fixation element and a pair of adjusting ends, wherein at least one of the adjusting ends can be pulled to reduce the size of the adjustable loop and to compress fragments of the fractured bone.

2. The assembly of claim 1, wherein the first fixation element and the second fixation element are selected from a grommet, a toggle, a button, a screw tip, a screw head, or a set screw head.

3. The assembly of claim 1, wherein the first fixation element and the second fixation element each have an external screw thread.

4. The assembly of claim 3, wherein an outer diameter of the first fixation element is greater than an outer diameter of the second fixation element.

5. The assembly of claim 1, wherein the first and second fixation elements are configured to be inset below an outer surface of the fractured bone.

6. The assembly of claim 1, wherein the sleeve of the first fixation element has a first keyed surface corresponding to a second keyed surface of the sleeve of the second fixation element.

7. The assembly of claim 6, wherein the first keyed surface is one of a protrusion, recess, or a polygon.

8. The assembly of claim 6, further comprising a drive mechanism in the first fixation element configured to drive both the first and second fixation elements by way of the first and second keyed surfaces.

11. The assembly of claim 1, wherein the female and male sleeves are integrally formed with the first and second fixation elements.

12. The assembly of claim 1, wherein the first fixation element defines at least two apertures sized to receive the pair of adjusting ends and the at least one adjustable loop.

9. An assembly for securing a fractured bone comprising:

a first fixation element configured to be secured within a first portion of the fractured bone, the first fixation element having one of a male or a female sleeve extending from the first fixation element;

a second fixation element configured to be secured within a second portion of the fractured bone, the second fixation element having the other of the male or female sleeve extending from the second fixation element and telescopically engaging the other of the male or female sleeve of the first fixation element; and

an adjustable flexible member construct extending between the first and second fixation elements, the adjustable flexible member construct having at least one adjustable loop coupled to the first fixation element and the second fixation element and a pair of adjusting ends, wherein at least one of the adjusting ends can be pulled to reduce the size of the adjustable loop and to compress fragments of the fractured bone, wherein the adjustable flexible member construct comprises a hollow braided or woven structure having a first of the pair of adjusting ends passed through a first aperture and through a longitudinal passage portion and out a second aperture to form the at least one adjustable loop.

10. The assembly of claim 9, wherein a second of the pair of adjusting ends is passed through the second aperture and through the longitudinal passage portion and out the first aperture to form a second adjustable loop, the second adjustable loop coupled to the first and second fixation elements.

13. An assembly for securing a first portion and a second portion of a fractured bone comprising:

a first fixation member having one of a male or female sleeve, a first coupling member and an external screw thread configured to be rotatably received within the first portion of the fractured bone;

a second fixation member having the other of the male or a female sleeve, a second coupling member, and an external screw thread configured to be rotatably received within the second portion of the fractured bone, wherein the male sleeve is telescopically engaging the female sleeve; and

an adjustable flexible member construct extending through the first and second fixation members, wherein the adjustable flexible member construct has at least one looped portion coupled to the first fixation member and the second fixation member and first and second ends passing through the second coupling member, wherein at least one of the first and second ends can be pulled to reduce a diameter of the at least one looped portion and to compress the first and second portions of the fractured bone.

14. The assembly of claim 13, wherein the female sleeve is rotationally keyed to the male sleeve.

15. The assembly of claim 13, wherein the female and male sleeves are integrally formed and extend from the respective first and second fixation members.

16. The assembly of claim 13, wherein the first coupling member is an eyelet and the second coupling member is a central plate.

17. An assembly for securing a first portion and a second portion of a fractured bone comprising:

a first fixation member having one of a male or female sleeve, a first coupling member and an external screw thread configured to be rotatably received within the first portion of the fractured bone;

a second fixation member having the other of the male or female sleeve, a second coupling member, and an external screw thread configured to be rotatably received within the second portion of the fractured bone, wherein the male sleeve is telescopically engaging the female sleeve; and

an adjustable flexible member construct extending between the first and second fixation members, wherein the adjustable flexible member construct has at least one looped portion coupled to the first fixation member and the second fixation member and first and second ends passing through the second coupling member, wherein at least one of the first and second ends can be pulled to reduce a diameter of the at least one looped portion and to compress the first and second portions of the fractured bone, wherein the adjustable flexible member construct comprises a hollow braided or woven structure having the first end passed through a first aperture and through a longitudinal passage portion and out a second aperture to form the at least one looped portion, where the longitudinal passage portion is attached to the first coupling member of the first fixation member.

18. The assembly of claim 17, wherein the second end is passed through the second aperture and through the longitudinal passage portion and out the first aperture to form a second looped portion.
