Bone plate extender and extension system for bone restoration and methods of use thereof
The disclosure includes a bone plate extender and extension system. The system includes a first bone plate extender and may additionally include a bone fixation element and/or an additional bone plate. The bone plate extender may be affixed to a bone portion at one end, for instance, a fractured bone portion, via a bone fixation element, and associated with a second bone plate at an opposite end, so as to facilitate alignment and stabilization of the bone and thereby correct and treat a bone fracture. The bone plate extender may include an extended body, which includes a bone plate engagement portion, a bone fixation portion, and an intercalating portion there between. In certain variations, the extended body is planar, and in certain variations the extended body is angled, curved or arced. Methods of using such bone plate extension systems for the reduction, restoration and treatment of bone fractures are also provided.
1. A bone plate extender, comprising an extended body, the extended body comprising:
a bone plate engagement portion comprising a bottom surface and a top surface, the bottom surface being substantially planar and configured for contacting a top surface of a bone plate;
a bone fixation portion adapted for being associated with a bone fixation element; and
an intercalating portion extending between the bone plate engagement portion and the bone fixation portion and comprising a bottom surface and a top surface, the bone plate engagement portion and the bone fixation portion being twisted relative to one another about a centerline of the extended body.
2. The bone plate extender of claim 1 , wherein a distance between the bottom and top surface of the bone plate engagement portion comprises a first thickness, and a distance between the bottom and top surface of the intercalating portion comprises a second thickness.
3. The bone plate extender of claim 2 , wherein the first thickness and second thickness comprises a unitary thickness.
4. The bone plate extender of claim 1 , wherein the intercalating portion is adapted so as to resist deformation.
5. The bone plate extender of claim 1 , wherein the intercalating portion further comprises a proximal portion including a proximal end, a distal portion including a distal end, an intermediary portion positioned between the proximal and the distal portions, a top surface, a bottom surface opposite the top surface, and a primary plane, wherein the primary plane corresponds to either the top surface or the bottom surface.
6. The bone plate extender of claim 5 , wherein the primary plane corresponds to the proximal portion, and the distal portion is out of plane with respect to the primary plane.
7. The bone plate extender of claim 6 , wherein one of the top surface or the bottom surface comprises one or more secondary planes.
8. The bone plate extender of claim 6 , wherein the distal portion is angled with respect to the proximal portion.
9. The bone plate extender of claim 6 , wherein the bone fixation portion is angled with respect to the primary plane.
10. The bone plate extender of claim 1 , wherein the bone fixation portion further comprises an opening extending between the top surface and a bone contacting surface, wherein the opening is configured for receiving a bone fixation element there through.
11. The bone plate extender of claim 10 , wherein the bone fixation element comprises a fastener.
12. The bone plate extender of claim 1 , wherein the bone plate engagement portion and the bone fixation portion are rotated relative to one another about the centerline to form a twist in the extended body.
13. The bone plate extender of claim 1 , wherein the centerline of the extended body includes a spiral curve along a twist between the bone plate engagement portion and the bone fixation portion.
14. A bone plate extender, comprising an extended body, the extended body comprising:
a bone plate engagement portion comprising a bottom surface and a top surface, the bottom surface being substantially planar and configured for contacting a top surface of a bone plate;
a bone fixation portion adapted for being associated with a bone fixation element; and
an intercalating portion extending between the bone plate engagement portion and the bone fixation portion and comprising a bottom surface and a top surface, the bone plate engagement portion and the bone fixation portion being twisted relative to one another about a centerline of the extended body, the bone plate engagement portion being bent along the centerline relative to the bone fixation portion.
15. The bone plate extender of claim 14 , wherein the bone plate engagement portion and the bone fixation portion are rotated relative to one another about the centerline to form a twist in the extended body.
16. The bone plate extender of claim 14 , wherein the centerline of the extended body includes a spiral curve along a twist between the bone plate engagement portion and the bone fixation portion.
