Abstract

Bone fixation devices and plates are disclosed. The bone fixation device includes a first portion, a second portion, and a third portion. The first portion includes at least one opening. The second portion includes at least one second opening. The third portion is positioned between the first portion and the second portion and is configured to guide the cutting of a bone. The bone fixation plate includes a first plate portion, a second plate portion, and a third plate portion. The first plate portion includes at least one screw hole for receiving a first bone screw. The second plate portion includes at least one slot for receiving a second bone screw. The third plate portion is positioned adjacent to the first and second plate portions and is configured to guide bone cutting A method of altering a bone using the bone fixation devices and plates is also disclosed.

First claim

Having thus described the preferred embodiments, the invention is now claimed to be:

1. A bone fixation device, comprising:
a first portion comprising a first surface having a first hole therethrough, a first longitudinal side, a second longitudinal side, and a first interior end closest to a second portion, the first longitudinal side and the second longitudinal side aligned relative to a first longitudinal dimension of the first portion, the first surface bounded by the first longitudinal side, the second longitudinal side, and the first interior end;
the second portion comprising a second surface having a second hole therethrough, a third longitudinal side, a fourth longitudinal side, and a second interior end closest to the first portion, the third longitudinal side and the fourth longitudinal side aligned relative to a second longitudinal dimension of the second portion, the second surface bounded by the third longitudinal side, the fourth longitudinal side, and the second interior end;
a third portion positioned between the first portion and the second portion, the third portion configured to guide the cutting of a bone;
the third portion comprising a cutting slot configured to receive a cutting device, the cutting slot bounded only by the first interior end, the second interior end and a third portion connecting portion connecting said first portion and said second portion; and
the slot comprising a gap between the first portion and the second portion, the gap opposite said connecting portion and providing communication between the slot and an exterior of the slot to allow access to the slot through the gap;
the first surface and the second surface separated by the slot;
wherein the third portion connecting portion comprises a tab portion extending downwardly from said first surface and said second surface, the tab portion bounding the cutting slot, and the tab portion extending from the first portion and the second portion in a direction parallel to axes of the first hole and the second hole.

2. The bone fixation device of claim 1 , wherein the first hole is configured for receiving at least a first bone screw for attachment to a first bone segment and the at least one second opening is configured for receiving at least one second bone screw for attachment to a second bone segment.

3. The bone fixation device of claim 1 , wherein the first interior end comprises a first cutting surface; and the second interior end comprises a second cutting surface, the first cutting surface and the second cutting surface being substantially parallel to each other.

4. The bone fixation device of claim 3 , wherein the first cutting surface and the second cutting surface are substantially perpendicular to the bottom surface of the bone fixation device.

5. The bone fixation device of claim 4 , wherein the first cutting surface and the second cutting surface are perpendicular to the first longitudinal dimension and/or the second longitudinal dimension.

6. The bone fixation device of claim 4 , wherein the first cutting surface and the second cutting surface are angled relative to a long axis of the bone fixation device.

7. The bone fixation device of claim 3 ,
wherein the tab portion extends substantially perpendicularly to the first longitudinal dimension and/or the second longitudinal dimension, and the tab portion has a third longitudinal dimension aligned relative to first longitudinal dimension and/or the second longitudinal dimension.

8. The bone fixation device of claim 1 , wherein the tab portion is configured to be at least one of angled or arcuate relative to a top surface of the bone fixation device.

9. The bone fixation device of claim 1 , wherein the first portion comprises a third hole.

10. The bone fixation device of claim 1 , wherein the second hole is a slot.

11. The bone fixation device of claim 1 , wherein the second portion comprises a third hole.

12. The bone fixation device of claim 11 , wherein second hole comprise a compression slot and the third hole comprises a compression screw hole.

13. A bone fixation device, comprising:
a first portion comprising a first surface having a first hole therethrough, a first longitudinal side, a second longitudinal side, and a first interior end closest to a second portion, the first longitudinal side and the second longitudinal side aligned relative to a first longitudinal dimension of the first portion, the first surface bounded by the first longitudinal side, the second longitudinal side, and the first interior end;
the second portion comprising a second surface having a second hole therethrough, a third longitudinal side, a fourth longitudinal side, and a second interior end closest to the first portion, the third longitudinal side and the fourth longitudinal side aligned relative to a second longitudinal dimension of the second portion, the second surface bounded by the third longitudinal side, the fourth longitudinal side, and the second interior end;
a third portion positioned between the first portion and the second portion, the third portion configured to guide the cutting of a bone;
the third portion comprising a cutting slot configured to receive a cutting device, the cutting slot bounded only by the first interior end, the second interior end and a third portion connecting portion connecting said first portion and said second portion; and
the slot comprising a gap between the first portion and the second portion, the gap opposite said connecting portion and providing communication between the slot and an exterior of the slot to allow access to the slot through the gap;
the first surface and the second surface separated by the slot; and

wherein the slot is located between the first hole and the second hole in a direction connecting axes of the first hole and the second hole.

14. A bone fixation device, comprising:
a first portion comprising a first surface having a first hole therethrough, a first longitudinal side, a second longitudinal side, and a first interior end closest to a second portion, the first longitudinal side and the second longitudinal side aligned relative to a first longitudinal dimension of the first portion, the first surface bounded by the first longitudinal side, the second longitudinal side, and the first interior end;
the second portion comprising a second surface having a second hole therethrough, a third longitudinal side, a fourth longitudinal side, and a second interior end closest to the first portion, the third longitudinal side and the fourth longitudinal side aligned relative to a second longitudinal dimension of the second portion, the second surface bounded by the third longitudinal side, the fourth longitudinal side, and the second interior end;
a third portion positioned between the first portion and the second portion, the third portion configured to guide the cutting of a bone;
the third portion comprising a cutting slot configured to receive a cutting device, the cutting slot bounded only by the first interior end, the second interior end and a third portion connecting portion connecting said first portion and said second portion; and
the slot comprising a gap between the first portion and the second portion, the gap opposite said connecting portion and providing communication between the slot and an exterior of the slot to allow access to the slot through the gap;
