Abstract

Bone plates for engaging bone members are described herein. The bone plates can receive one or more screws to secure the bone plates to an underlying bone member. The one or more screws can be inserted into bone plate holes that can be considered locking or non-locking. The bone plates described herein can have particular combinations of locking and/or non-locking holes. In addition, instruments such as distal and proximal aiming guides can accompany the bone plates to guide one or more screws into the bone plates.

First claim

What is claimed is:

1. A system for treating a fracture in a bone comprising: a bone plate configured to engage a bone,
the bone plate comprising a head portion, a neck portion extending from the head portion and a shaft portion extending from the neck portion,
wherein the head portion comprises a first row of holes comprising at least three holes and a second row of holes comprising at least three holes for receiving fasteners therein,
wherein the neck portion comprises at least three kickstand holes for receiving fasteners therein, and
wherein the shaft portion comprises at least four holes for receiving fasteners therein, wherein one or more of the at least four holes in the shaft portion is a compression slot;
a plurality of fasteners received in the head portion and positioned in the first row of holes and/or the second row of holes; and
at least one fastener received in the shaft portion and positioned in at least one of the at least four hole;
the bone plate further including at least one indentation adapted to receive a corresponding pin of an aiming guide and
an aiming guide attachment hole adapted to receive an attachment post of the aiming guide, wherein the at least one indentation includes a plurality of indentations positioned near the aiming guide attachment hole each adapted to receive a corresponding pin of the attachment post of the aiming guide;
wherein a width of the head portion is greater than a width of the neck portion and a width of the shaft portion,
wherein the head portion extends laterally beyond the neck portion on one side relative to a longitudinal axis of the bone plate,
wherein the first row of holes are positioned along a first axis and the second row of holes are positioned along a second axis,
and
wherein the first axis and the second axis extend generally perpendicularly to the longitudinal axis of the bone plate.

2. The system of claim 1 , wherein the first row of holes is comprised of holes that are smaller than holes in the second row of holes.

3. The system of claim 2 , wherein the first row of holes is comprised of holes having a diameter between 2 and 3 mm, and the second row of holes is comprised of holes having a diameter between 3 and 4 mm.

4. The system of claim 2 , wherein the first row of holes is closer to the proximal end than the second row of holes.

5. The system of claim 1 , wherein the neck portion comprises an elongated positioning slot.

6. The system of claim 5 , wherein the elongated positioning slot is at least twice a length of any of the holes on the bone plate.

7. A system for treating a fracture in a bone comprising: a bone plate configured to engage a bone,
the bone plate comprising a proximal end, a distal end, a head portion, a neck portion and a shaft portion,
wherein the head portion comprises a first row of holes comprising at least three holes and a second row of holes comprising at least three holes for receiving a plurality of fasteners therein,
wherein the neck portion comprises at least three kickstand holes for receiving fasteners therein, and
wherein the shaft portion comprises a pair of holes for receiving a fastener therein, wherein the pair of holes comprises a stacked hole adjacent a compression slot;
a plurality of fasteners received in the head portion and positioned in the first row of holes and/or the second row of holes, wherein at least one of the plurality of fasteners is non-threaded;
and
at least one fastener received in the shaft portion and positioned in at least one of the pair of hole;
the bone plate further including at least one indentation on an upper surface thereof adapted to receive a corresponding pin of an aiming guide and
an aiming guide attachment hole adapted to receive an attachment post of the aiming guide, wherein the at least one indentation includes a plurality of indentations positioned near the aiming guide attachment hole each adapted to receive a corresponding pin of the attachment post of the aiming guide;
wherein a width of the head portion is greater than a width of the neck portion and a width of the shaft portion,
wherein the head portion extends laterally beyond the neck portion on one side of a longitudinal axis of the bone plate,
wherein the neck portion extends outwardly beyond the shaft portion on one side of the longitudinal axis,
wherein the first row of holes are positioned along a first axis and the second row of holes are positioned along a second axis, and wherein the first axis and the second axis extend generally perpendicularly to the longitudinal axis of the bone plate.

8. The system of claim 7 , further comprising an aiming guide for assisting in the insertion of one or more of the fasteners into the bone plate.

9. The system of claim 8 , wherein the aiming guide comprises a distal aiming guide capable of attachment to a proximal aiming guide.

10. The system of claim 9 , wherein the proximal aiming guide comprises a rotatable dial.

11. The system of claim 7 , wherein the head portion further comprises at least one multi-functional hole capable of receiving a k-wire or suture therein.

12. The system of claim 11 , wherein the at least one multi-functional hole is positioned adjacent to an undercut in the bone plate.

13. The system of claim 7 , wherein the first row of holes is comprised of holes that are smaller than holes in the second row of holes.

14. The system of claim 7 , wherein the shaft portion comprises a scalloped contact surface.

15. The system of claim 7 , wherein the at least one fastener received in the shaft portion is threaded.
