Abstract

A bone repair system and method for percutaneously fixing a first bone segment to a second bone segment, such as rib bone segments, in a body of a patient include drilling a first hole through the first bone segment and a second hole through the second bone segment, and feeding a first tether through the first hole and a second tether through the second hole, each tether having a proximal end and a distal end. The first and second tether distal ends are withdrawn from the body while the first and second tether proximal ends have not passed through the first and second bone segments, respectively. A reinforcing member, such as a bone plate, having first and second openings, is passed onto the first and second tether distal ends, and the reinforcing member is pulled into engagement with the first and second bone segments guided by the tethers. The reinforcing member is secured to the first bone segment with a first fastener assembly through the first hole and the first opening and to the second bone segment with a second fastener assembly through the second hole and the second opening to fix the first bone segment to the second bone segment.

First claim

What is claimed is:

1. A system for the percutaneous repair of first and second bone segments of a fractured rib bone in a patient, the bone segments each having an internal surface and an opposing external surface, the system comprising:
at least a first and second tether each having a proximal end and a distal end;
a reinforcing member having at least a first opening and a second opening, wherein the distal end of the first tether is arranged to be passed through the first opening and the distal end of the second tether is arranged to be passed through the second opening; and
a first fastener assembly arranged to secure the reinforcing member to the first bone segment through the first opening, and a second fastener assembly arranged to secure the reinforcing member to the second bone segment through the second opening;
wherein the first fastener assembly includes a first inner fastener and the second fastener assembly includes a second inner fastener, the first and second inner fasteners arranged to be disposed at the internal surface of the first and second bone segments and arranged to engage the reinforcing member against the internal surface of the first and second bone segments;
wherein the first fastener assembly further includes a first outer fastener and the second fastener assembly further includes a second outer fastener, the first and second outer fasteners arranged to be disposed at the external surface of the first and second bone segments and arranged to engage the reinforcing member against the external surface of the first and second bone segments;
wherein the first and second tethers are arranged to pull the reinforcing member into engagement with the internal surface of the first and second bone segments guided by the tethers to secure the reinforcing member to the internal surface of the first bone segment and to the internal surface of the second bone segment to fix the first bone segment to the second bone segment;
wherein the first outer and inner fasteners are arranged to concurrently abut the external and internal surfaces, respectively, and be secured to each other through the first opening, and the second outer and inner fasteners are arranged to concurrently abut the external and internal surfaces, respectively, and be secured to each other through the second opening to secure the reinforcing member to the first and second bone segments.

2. The system of claim 1 , wherein the reinforcing member is arranged to be adhesively joined to the first and second bone segments.

3. The system of claim 1 , wherein the first and second outer fasteners each have a channel for passing the first and second tethers therethrough, respectively.

4. The system of claim 1 , wherein the first and second inner fasteners are arranged to be secured on the distal ends of the first and second tethers, respectively, to retain the reinforcing member on the first and second tethers.

5. The system of claim 1 , further comprising a stop member arranged to be received on each tether distal end subsequent to the reinforcing member.

6. The system of claim 1 , further comprising a blind fastener having an outer diameter which is expandable to prevent removal from a bore after insertion, the blind fastener including deployable positive engagement means for engagement of the reinforcing member.

7. The system of claim 1 , wherein the reinforcing member includes a patch.

8. A kit for surgical repair of a fractured bone involving a first bone segment and a second bone segment, comprising:
a hollow trocar for engaging the first and second bone segments;
a drill guide arranged to be received through the trocar for facilitating drilling of a first hole in the first bone segment and a second hole in the second bone segment;
at least a first and second tether each having a proximal end and a distal end;
at least one reinforcing member having at least a first opening and a second opening, wherein the reinforcing member includes a patch comprising a fiber mesh and resin matrix, wherein the distal end of the first tether is arranged to be passed through the first opening and the distal end of the second tether is arranged to be passed through the second opening;
wherein the first and second tethers are arranged to be received through the first and second holes in the first and second bone segments, respectively, for pulling the reinforcing member into engagement with the first and second bone segments guided by the tethers and securing the reinforcing member to the first bone segment and to the second bone segment to fix the first bone segment to the second bone segment.

9. The kit of claim 8 , wherein the patch includes an adhesive for joining the patch to the first and second bone segments.

10. The kit of claim 8 , further comprising a first fastener assembly to secure the patch to the first bone segment through the first hole and the first opening and a second fastener assembly to secure the patch to the second bone segment through the second hole and the second opening.

11. The kit of claim 10 , wherein the first fastener assembly includes a first inner fastener and a first outer fastener arranged to be secured through the first hole, and the second fastener assembly includes a second inner fastener and a second outer fastener arranged to be secured through the second hole to engage the reinforcing member with the first and second bone segments.

12. The kit of claim 11 , wherein the first and second outer fasteners each have a channel for passing the first and second tethers therethrough, respectively.

13. The kit of claim 11 , wherein the first and second tether distal ends are threaded for receiving the first and second inner fasteners thereon, respectively.

14. The kit of claim 11 , further comprising a drive tool arranged to be received through the trocar for securing the outer fasteners to the inner fasteners.

15. The kit of claim 11 , further comprising at least two stop members to be placed on each tether distal end for retaining the reinforcing member and inner fasteners on the tethers.

16. The kit of claim 8 , further comprising a blind fastener including deployable positive engagement means for engagement of the reinforcing member.

17. The kit of claim 8 , wherein the first and second bone segments comprise rib bone segments.

18. The system of claim 4 , wherein the first and second tether distal ends are threaded for receiving the first and second inner fasteners thereon, respectively.

19. The system of claim 1 , wherein the reinforcing member has a first configuration during insertion into the patient and a second, deployed configuration once inserted into the patient.

20. The system of claim 1 , wherein the reinforcing member is arranged to be secured to the pleural lining on the internal surface of the first and second bone segments.

21. The system of claim 1 , wherein the reinforcing member is arranged to extend to engage one or more additional, non-fractured rib bones.

22. The system of claim 7 , wherein the patch includes a resin matrix.

23. The system of claim 1 , wherein the reinforcing member includes metal.

24. A system for the percutaneous repair of first and second bone segments of a fractured rib bone in a patient, the bone segments each having an internal surface and an opposing external surface, the system comprising:
at least a first and second tether each having a proximal end and a distal end;
a reinforcing member having a
