Abstract

A bone plate incorporating a length adjusting elongate hole formed in a shaft portion thereof, along with corresponding methods of use. In one embodiment, the length adjusting elongate hole is configured to receive one or more bone fixation devices (e.g., bone screws). In use, the bone fixation device positioned within the length adjusting elongate hole may be partially loosened, without removal, to enable the patient's bone to be adjusted (e.g., loosening the bone fixation device within the length adjusting elongate hole allows the surgeon to adjust the position of the patient's bone, and hence the bone fixation device coupled thereto, relative to the bone plate). Once properly adjusted, the bone fixation device positioned within the length adjusting elongate hole may be retightened. In various embodiments, the length adjusting elongate hole is configured so that, in use, each of the plurality of bone fixation openings remains available to a surgeon.

Claims (31)

1. A bone plate comprising:

a shaft portion including a central longitudinal axis, an upper surface, a bottom surface, and a plurality of bone fixation openings extending between the upper and bottom surfaces, each of the plurality of bone fixation openings being arranged and configured to receive a bone fixation device for coupling the bone plate to a patient's bone; and

a length adjusting elongate hole formed in the shaft portion, the length adjusting elongate hole including a central longitudinal axis, the length adjusting elongate hole arranged and configured to enable a length of the patient's bone to be adjusted without requiring the bone plate to be completely decoupled from the patient's bone;

wherein the central longitudinal axis of the length adjusting elongate hole is aligned with the central longitudinal axis of the shaft portion, the length adjusting elongate hole extending between adjacent bone fixation openings formed in the shaft portion of the bone plate so that the length adjusting elongate hole is in communication with the adjacent bone fixation openings;

wherein the adjacent bone fixation openings are a first locking screw opening and a second locking screw opening;

wherein the first and second locking screw openings each comprise, respectively, a central longitudinal axis;

wherein the central longitudinal axis of the first locking screw opening and the central longitudinal axis of the second locking screw opening both extend parallel to the central longitudinal axis of the shaft portion; and

wherein the central longitudinal axis of the first locking screw openings is positioned on an opposite side of the central longitudinal axis of the shaft portion from the central longitudinal axis of the second locking screw opening.

2. The bone plate of claim 1 , wherein the length adjusting elongate hole includes a length at least twice a diameter of a bone fixation opening.

3. The bone plate of claim 1 , wherein the length adjusting elongate hole includes a dished or recessed region arranged and configured to enable a bone fixation device to be recessed relative to the upper surface of the bone plate.

4. The bone plate of claim 3 , wherein the length adjusting elongate hole includes a recess portion on the bottom surface.

5. A method of fracture reduction utilizing a bone plate with a length adjusting elongate hole formed in a shaft portion of the bone plate, the method comprising:

coupling a portion of the bone plate to a patient's bone utilizing one or more bone fixation devices;

inserting a bone fixation device into the length adjusting elongate hole, the bone fixation device being positioned within one side of the length adjusting elongate hole;

reducing an amount of provisional compression from the bone fixation device;

adjusting a length of the patient's bone;

compressing the bone plate against the patient's bone using the previously inserted bone fixation device; and

inserting a locking screw into an adjacent locking screw opening formed in the bone plate;

wherein a central longitudinal axis of the length adjusting elongate hole is aligned with a central longitudinal axis of the bone plate, the length adjusting elongate hole extending between adjacent bone fixation openings formed in the bone plate so that the length adjusting elongate hole is in communication with the adjacent bone fixation openings;

wherein the adjacent bone fixation openings are a first locking screw opening and a second locking screw opening;

wherein the first and second locking screw openings each comprise, respectively, a central longitudinal axis;

wherein the central longitudinal axis of the first locking screw opening and the central longitudinal axis of the second locking screw opening both extend parallel to the central longitudinal axis of the shaft portion; and

wherein the central longitudinal axis of the first locking screw openings are is positioned on an opposite side of the central longitudinal axis of the shaft portion from the central longitudinal axis of the second locking screw opening.

6. The method of claim 5 , wherein the bone plate is provisionally held against the patient's bone during inserting the bone fixation device into the length adjusting elongate hole.

7. The method of claim 5 , wherein adjusting a length of the patient's bone comprises reducing or compressing the patient's bone.

8. The method of claim 5 , wherein adjusting a length of the patient's bone comprises lengthening or distracting the patient's bone.

9. The method of claim 8 , further comprising reducing the patient's bone.

10. The method of claim 9 , wherein reducing the patient's bone is accomplished prior to coupling a portion of the bone plate to the patient's bone.

11. The method of claim 5 , wherein the length adjusting elongate hole includes a length at least twice a diameter of a bone fixation opening.

12. The method of claim 5 , wherein the length adjusting elongate hole includes a dished or recessed region arranged and configured to enable a bone fixation device to be recessed relative to the upper surface of the bone plate.

13. The method of claim 5 , wherein the length adjusting elongate hole includes a recess portion on the bottom surface.
