Bone plating system and method
A bone plate can be used to fixate one or more bones. In some examples, the bone plate defines an elongated body having a plurality of fixation holes arrayed at different points along the length of the body. For example, the bone plate may have opposed fixation holes separated by a bridge. The bone plate may be bent or shaped along a central longitudinal axis extending through the elongated body and also twisted around the central longitudinal axis. The bending and twisting can position each fixation hole of the elongated body in a different plane in three-dimensional space.
1. A bone plate comprising:
a body having a length defining a central longitudinal axis and a width defining an extent of the bone plate transverse to the central longitudinal axis, and wherein the body includes a top surface and a bone facing surface opposite the top surface, the bone facing surface including a first surface;
a first fixation hole extending through the body from the top surface to the bone facing surface;
a pad extending out a distance from the first surface at a location on the bone facing surface adjacent the first fixation hole; and
a channel on the bone facing surface extending along at least a portion of the central longitudinal axis adjacent the first fixation hole, the channel dividing the pad into a first pad portion and a second pad portion.
2. The bone plate of claim 1 , wherein the width of the body is greater at a location along the central longitudinal axis having the first fixation hole compared to the width of the body at a location remote from the first fixation hole.
3. The bone plate of claim 1 , wherein the location on the bone facing surface adjacent the first fixation hole is defined between a perimeter of the first fixation hole and a width of the body.
4. The bone plate of claim 1 , further comprising:
an attachment member at least partially within the first fixation hole.
5. The bone plate of claim 1 , wherein the channel defines a surface spaced from the first surface less than the pad.
6. The bone plate of claim 1 , wherein all locations along a perimeter of the first fixation hole on the bone facing surface interface with the channel or the pad.
7. The bone plate of claim 1 , further comprising:
a second fixation hole spaced from the first fixation hole along the central longitudinal axis, the second fixation hole being separated from the first fixation hole by a region configured to concentrate bending stresses; and
a pad extending out a distance from the first surface at a location on the bone facing surface adjacent the second fixation hole.
8. The bone plate of claim 7 , wherein the width of the body increases at a location along the central longitudinal axis having the second fixation hole.
9. The bone plate of claim 7 , further comprising:
a channel on the bone facing surface extending along at least a portion of the central longitudinal axis adjacent the second fixation hole, and wherein the channel adjacent the second fixation hole is aligned along the central longitudinal axis with the channel on the bone facing surface adjacent the first fixation hole.
10. The bone plate of claim 7 , further comprising:
a third fixation hole spaced from the second fixation hole along the central longitudinal axis; and
a bridge extending along the central longitudinal axis between the second fixation hole and the third fixation hole.
11. The bone plate of claim 10 , wherein the width of the body at locations along the central longitudinal axis having the second and the third fixation holes is greater than the width of the body along the bridge.
12. The bone plate of claim 10 , further comprising:
a first pad extending out a distance from the first surface at a location on the bridge.
13. The bone plate of claim 12 , further comprising:
a second pad extending out a distance from the first surface at a location on the bridge and spaced from the first pad along the central longitudinal axis of the body.
14. The bone plate of claim 12 , wherein the first pad and the second pad are each bordered by regions configured to concentrate bending stresses.
15. The bone plate of claim 1 , wherein the pad is adjacent a region configured to concentrate bending stresses.
16. The bone plate of claim 1 , wherein the channel bisects the pad into the first pad portion and the second pad portion.
17. The bone plate of claim 1 , wherein the channel projects out from the first surface a distance less than the pad.
18. The bone plate of claim 1 , further comprising a radiused surface defining a transition between the channel and the pad.
