Abstract

A device for treating a bone includes a plate having a connector opening and a first fastener receiving lumen extending therethrough, the first fastener receiving lumen being sized and shaped to receive therethrough a bone fastener and a nail sized and shaped for insertion in a medullary canal of a target bone, the nail including an elongate shaft and an opening extending through the shaft in combination with a connector sized and shaped so that, when the plate is positioned over a target portion of bone in a desired alignment with the nail, the connector may be passed into the target portion of bone via the connector opening and into the opening of the nail, the shape of the connector engaging the opening to form an angularly stable connection between the plate and the nail.

First claim

What is claimed is:

1. A device for treating a bone, comprising:
a plate having a connector opening and a first fastener receiving lumen extending therethrough, the first fastener receiving lumen being sized and shaped to receive therethrough a bone fastener, the plate further having a recessed portion surrounding the connector opening;
a nail sized and shaped for insertion in a medullary canal of a target bone, the nail including an elongate shaft and an opening extending through the shaft; and
a connector sized and shaped so that, when the plate is positioned over a target portion of bone in a desired alignment with the nail, the connector may be passed into the target portion of bone via the connector opening and into the opening of the nail, the shape of the connector mechanically engaging and interlocking with the opening to form an angularly stable connection between the plate and the nail, the shape of the connector configured to fit within the recessed portion.

2. The device of claim 1 , wherein the plate has a substantially concave bone-facing surface generally matching a contour of the target portion of bone.

3. The device of claim 1 , wherein an inner surface of the connector opening is threaded.

4. The device of claim 3 , wherein the connector includes one of a spiral blade and a straight blade.

5. The device of claim 4 , further comprising a threaded blade cap including a threaded outer surface sized to threadedly engage the connector opening.

6. The device of claim 1 , wherein the connector includes a bone screw, a portion of which is adapted to mate with threads of the first fastener receiving lumen.

7. The device of claim 1 , wherein the plate includes a suture opening extending therethrough from a bone-facing surface thereof to an outer surface opposite the bone-facing surface.

8. The device of claim 1 , wherein the plate is substantially square.

9. The device of claim 1 , wherein the plate is substantially rectangular.

10. The device of claim 1 , wherein the plate is substantially triangular.

11. A device for treating a bone, comprising:
a plate having a connector opening and a first fastener receiving lumen extending therethrough, the first fastener receiving lumen being sized and shaped to receive therethrough a bone fastener;
a nail sized and shaped for insertion in a medullary canal of a target bone, the nail including an elongate shaft and an opening extending through the shaft; and
a connector sized and shaped so that, when the plate is positioned over a target portion of bone in a desired alignment with the nail, the connector may be passed into the target portion of bone via the connector opening and into the opening of the nail, the shape of the connector engaging the opening to form an angularly stable connection between the plate and the nail, wherein the connector opening includes at least one locking element receiving location and the connector includes a corresponding at least one elongate locking element that is insertable, when the plate is positioned over the target portion of bone in the desired alignment with the nail, into the opening via a respective one of the locking element receiving locations.

12. The device of claim 11 , wherein the at least one locking element receiving location comprises discrete holes extending through the plate separate from one another.

13. The device of claim 11 , wherein the at least one locking element receiving location defines a central axis substantially along which a locking element inserted therethrough will pass into the opening, the central axes of the locking element receiving locations being angled relative to one another so that locking elements inserted therethrough into the slot will flare outward relative to one another to non-rotatably engage the slot.

14. The device of claim 11 , wherein the locking element is a single connector connecting the plate and the nail.

15. A method of treating a bone, comprising the steps of:
securing to a target portion of a bone to be treated a plate including a connector opening and a fastener opening extending therethrough, the plate further having a recessed portion surrounding the connector opening;
inserting a fastener through the fastener opening;
inserting into a medullary canal of the bone a nail including an elongate shaft and an opening extending through the shaft transverse to a longitudinal axis of the shaft;
inserting a connector through the target portion of the bone via the connector opening and into the opening of the nail, at least a portion of the connector being shaped to mechanically engage and interlock with the opening of the nail so that the connector is non-rotatable therein; and
connecting the connector to the connector opening, a further portion of the connector configured to fit within the recessed portion.

16. The method of claim 15 , wherein the connector includes one of a spiral blade and a straight blade.

17. The method of claim 15 , further comprising coupling the connector to the plate to non-rotatably couple the plate and the nail.

18. A device for treating a bone, comprising:
a plate having a connector opening and a first fastener receiving lumen extending therethrough, the first fastener receiving lumen being sized and shaped to receive therethrough a bone fastener;
a nail sized and shaped for insertion in a medullary canal of a target bone, the nail including an elongate shaft and an opening extending through the shaft; and
a connector sized and shaped so that, when the plate is positioned over a target portion of bone in a desired alignment with the nail, the connector may be passed into the target portion of bone via the connector opening and into the opening of the nail, the shape of the connector engaging the opening to form an angularly stable connection between the plate and the nail, wherein an inner surface of the connector opening is threaded, wherein the connector includes one of a spiral blade and a straight blade, and wherein the spiral blade includes a blade screw opening and wherein the device further comprises a blade screw sized for insertion through the blade cap into the blade screw opening to secure the spiral blade to the plate.

19. A device for treating a bone, comprising:
a plate having a connector opening and a first fastener receiving lumen extending therethrough, the first fastener receiving lumen being sized and shaped to receive therethrough a bone fastener;
a nail sized and shaped for insertion in a medullary canal of a target bone, the nail including an elongate shaft and an opening extending through the shaft; and
a connector sized and shaped so that, when the plate is positioned over a target portion of bone in a desired alignment with the nail, the connector may be passed into the target portion of bone via the connector opening and into the opening of the nail, the shape of the connector engaging the opening to form an angularly stable connection between the plate and the nail, wherein an inner surface of the connector opening is threaded, wherein the connector includes one of a spiral blade and a straight blade, and further comprising a second fastener receiving lumen, central axes of the first and second fastener receiving lumens being aligned relative to one another so that fasteners inserted therethrough into the bone diverge from one another as they move into the bone.

20. A method of treating a bone, comprising the steps of:
securing to a target portion of a bone to be treated a plate including a connector opening and a fa
