Abstract

A method of fixing a proximal bone mass to a distal bone mass can include driving a guide wire through the proximal bone mass and the distal bone mass to define a path through the proximal bone mass and the distal bone mass. The method can include inserting a suture from the proximal bone mass into the distal bone mass along the path defined by the guide wire and fixing the suture to the distal bone mass. The method can further include tensioning the suture to draw the distal bone mass against the proximal bone mass.

First claim

1 . A method of fixing a proximal bone mass to a distal bone mass, comprising:
driving a guide wire through the proximal bone mass and the distal bone mass to define a path through the proximal bone mass and the distal bone mass; inserting a suture from the proximal bone mass into the distal bone mass along the path defined by the guide wire; fixing the suture to the distal bone mass; and tensioning the suture to draw the distal bone mass against the proximal bone mass.

2 . The method of claim 1 , further comprising:
drilling a drive-in screw into at least the proximal bone mass along the path defined by the guide wire.

3 . The method of claim 2 , wherein the drive-in screw is driven through the proximal bone mass into the distal bone mass.

4 . The method of claim 2 , wherein the drive-in screw is withdrawn from at least the proximal bone mass following fixation of the suture to the distal bone mass.

5 . The method of claim 2 , wherein the drive-in screw defines a center channel for receiving the suture.

6 . The method of claim 1 , wherein the suture includes an expandable nose portion.

7 . The method of claim 6 , further comprising:
tensioning the suture when the nose portion is positioned within the distal bone mass to expand the nose portion and fix the suture to the distal bone mass.

8 . The method of claim 6 , further comprising:
inserting the suture through the distal bone mass such that the nose portion protrudes through a distal opening in the distal bone mass formed by the guide wire; and tensioning the suture to expand the nose portion and prevent withdrawal of the suture through the distal opening thereby fixing the suture to the distal bone mass.

9 . The method of claim 8 , wherein the suture includes a tail portion having engagement features engagable to a bone surface of at least one of the distal bone mass and the proximal bone mass.

10 . The method of claim 9 , further comprising:
fixing the tail portion within at least the distal bone mass; wherein tensioning the suture draws the nose portion against the tail portion to facilitate expansion of the nose portion against the distal bone portion.

11 . The method of claim 1 , wherein the proximal bone mass is larger than the distal bone mass.

12 . A system for fixing a proximal bone mass to a distal bone mass, comprising:
a guide wire configured to be driven through the proximal bone mass and the distal bone mass to define a path through the proximal bone mass and the distal bone mass; and a suture insertable through the proximal bone mass into the distal bone mass along the path defined by the guide wire; wherein the suture is configured to be fixed to the distal bone mass and tensioned to draw the distal bone mass against the proximal bone mass.

13 . The system of claim 12 , further comprising:
a drive-in screw defining a center channel for receiving the suture and configured to be drilled into at least the proximal bone mass along the path defined by the guide wire.

14 . The system of claim 13 , wherein the drive-in screw is driven through the proximal bone mass into the distal bone mass.

15 . The system of claim 13 , wherein the drive-in screw is configured to be withdrawn from at least the proximal bone mass following fixation of the suture to the distal bone mass.

16 . The system of claim 12 , wherein the suture further comprises:
a nose portion configured to expand radially when the suture is tensioned.

17 . The system of claim 16 , wherein the suture further comprises:
a tail portion having one or more engagement features engagable to a bone surface of at least one of the distal bone mass and proximal bone mass; wherein the tail portion is configured to engage the bone surface to fix the tail portion within at least the distal bone mass such that the suture can be tensioned to draw the nose portion against the tail portion to facilitate expansion of the nose portion against the distal bone mass.

18 . The system of claim 12 , wherein the proximal bone mass is larger than the distal bone mass.

19 . A system for fixing a proximal bone mass to a distal bone mass, comprising:
a guide wire configured to be driven through the proximal bone mass and the distal bone mass to define a path through the proximal bone mass and the distal bone mass; and a suture insertable through the proximal bone mass into the distal bone mass along the path defined by the guide wire, the suture comprising:
a nose portion configured to expand radially when the suture is tensioned, and
a tail portion having one or more engagement features engagable to a bone surface of at least one of the distal bone mass and proximal bone mass,
wherein the tail portion is configured to engage the bone surface to fix the tail portion within at least the distal bone mass such that the suture can be tensioned to draw the nose portion against the tail portion to facilitate expansion of the nose portion against the distal bone mass,
wherein the suture is configured to be fixed to the distal bone mass and tensioned to draw the distal bone mass against the proximal bone mass.

20 . The system of claim 19 , wherein the tail portion comprises:
a drive-in screw defining a center channel for receiving the suture and configured to be drilled into at least the proximal bone mass along the path defined by the guide wire.
