Abstract

An intramedullary nail includes one or more nail openings extending therethrough. The intramedullary nail is implantable within a medullary canal of the bone. A bone plate is configured to engage an outer surface of the bone. The bone plate includes one or more plate openings extending therethrough. The plate openings are spaced about the bone plate such that the bone plate is positionable to axially align the plate openings with the nail openings when the intramedullary nail is implanted within the medullary canal of the bone. An aiming guide includes one or more targeting openings. The targeting openings are spaced about the aiming guide such that the aiming guide is positionable to axially align the targeting openings with the plate openings and the nail openings for extending one or more stabilizing fasteners therethrough when the intramedullary nail is implanted within the medullary canal of the bone.

First claim

What is claimed:

1. A system for treating a fracture in a bone, the system comprising:
an intramedullary nail including one or more nail openings extending therethrough for receiving one or more stabilizing fasteners, the intramedullary nail implantable within a medullary canal of the bone;
a bone plate configured to engage an outer surface of the bone, the bone plate including one or more plate openings extending therethrough for receiving the one or more stabilizing fasteners, the one or more plate openings spaced about the bone plate such that the bone plate is positionable to axially align the one or more plate openings with the one or more nail openings when the intramedullary nail is implanted within the medullary canal of the bone;
an aiming guide including one or more targeting openings for receiving the one or more stabilizing fasteners, the one or more targeting openings spaced about the aiming guide such that the aiming guide is positionable to axially align the one or more targeting openings with the one or more plate openings and the one or more nail openings for extending the one or more stabilizing fasteners therethrough when the intramedullary nail is implanted within the medullary canal of the bone; and
an insertion tool coupleable to the intramedullary nail and the aiming guide, wherein the insertion tool includes a handle and the intramedullary nail couples to a lower portion of the handle and the aiming guide couples to an upper portion of the handle.

2. The system of claim 1 , wherein the aiming guide is positioned such that the one or more targeting openings are axially aligned with the one or more nail openings when the insertion tool is coupled to the intramedullary nail and the aiming guide.

3. The system of claim 2 , wherein the insertion tool includes an insertion shaft extending from the handle, the insertion shaft including one or more orientation tabs at a distal end thereof.

4. The system of claim 2 , wherein the insertion tool includes an insertion shaft extending from the handle, the insertion shaft including one or more grooves defined in at a distal portion thereof.

5. The system of claim 2 , wherein the insertion tool includes an insertion shaft extending at least partially through the handle, the insertion shaft including a flange at a proximal portion thereof seated in a groove defined in a proximal surface of the handle.

6. The system of claim 2 , wherein the insertion tool includes an insertion shaft and a connection bolt, the connection bolt extending axially through the insertion shaft such that the connection bolt is axially translatable a predetermined distance.

7. The system of claim 2 , wherein the insertion tool includes an insertion shaft and a connection bolt, the connection bolt extending axially through the insertion shaft, the insertion shaft including one or more internal threads, the connection bolt including one or more external threads configured to engage or cooperate with the one or more internal threads of the insertion shaft.

8. The system of claim 2 , wherein the insertion tool includes an insertion shaft and a connection bolt, the connection bolt extending axially through the insertion shaft, the connection bolt including one or more external threads positionable in a cavity defined by the insertion shaft.

9. The system of claim 2 , wherein the insertion tool includes an insertion shaft and an assembly shaft extending axially through the insertion shaft such that a distal end of the assembly shaft extends beyond a distal end of the insertion shaft.

10. The system of claim 2 , wherein the insertion tool includes a connection bolt defining an undercut groove and an assembly shaft including a latching feature that interfaces with the undercut groove in the connection bolt.

11. The system of claim 2 , wherein the insertion tool includes a connection bolt including one or more internal threads, and a backslap shaft including one or more external threads configured to engage the one or more internal threads.

12. The system of claim 2 , wherein the aiming guide includes one or more locating pins and the insertion tool includes one or more locating pin openings defined therein for receiving the one or more locating pins.

13. The system of claim 2 , wherein the aiming guide includes a threaded knob and the insertion tool includes a threaded insert defined therein for receiving the threaded knob.

14. The system of claim 1 , wherein the aiming guide has a wishbone-shaped configuration including a first leg and a second leg, a first targeting opening of the one or more targeting openings extending through the first leg, a second targeting opening of the one or more targeting openings extending through the second leg.

15. The system of claim 1 , wherein the aiming guide includes one or more retention mechanisms configured to control a movement of one or more driver sleeves extended through the one or more targeting openings.
