Abstract

A bone plate including a main bone plate body having two opposing curved sections adapted for a clavicle; a bendable waist portion narrower than the main body of the bone plate; and a node at each end of the main body connected to the main body by a bridge portion which is narrower than the main body, wherein the bridge includes a cut-out relief portion on a bottom side of the bone plate.

First claim

The claimed invention is:

1. A bone plate comprising:
a main bone plate body having an S-shape defining two opposing curved sections adapted for a clavicle;
a bendable waist portion narrower than the main body of the bone plate and located between the two opposing curved sections; and
a first node and a second node, with the first node at the end of one of the two opposing curved sections and the second node at the end of the other of the two opposing curved sections;
wherein the main body includes a bone-facing bottom surface positioned against the bone when implanted and an opposite, upper surface facing away from the bone when implanted, and wherein the main body includes one or more slots extending all the way through the main bone plate body from the bone-facing bottom surface to the opposite, upper surface, one or more of the slots have a cut-out region on the bottom surface of the bone plate at a periphery of the slot, the slot being configured to receive a bending iron positioned within the slot.

2. The bone plate of claim 1 , wherein each node is connected to the end of one of the two opposing curved sections of the main body by a bridge portion which is narrower than the main body, wherein the bridge includes a cut-out relief portion on a bottom side of the bone plate.

3. The bone plate of claim 1 , wherein the main body includes one or more bone-shaped holes.

4. The bone plate of claim 3 , wherein the one or more bone-shaped holes have a cut-out relief portion on a bottom side of the bone plate.

5. The bone plate of claim 1 wherein the bone plate is configured for a superior implant on the clavicle and each of the opposing curved sections defines a radius, with one radius in the range of 60 mm to 90 mm and the other radius in the range 83 mm to 100 mm.

6. The bone plate of claim 5 , wherein the waist portion is located between the two curved sections.

7. The bone plate of claim 1 , further including a plurality of holes in the main body configured to receive fasteners.

8. The bone plate of claim 1 , wherein the bone plate is configured for distal clavicle implant.

9. The bone plate of claim 8 , wherein an end of the bone plate includes a plurality of additional nodes connected to the main body by bendable bridges.

10. A system comprising:
three superior implant bone plates ranging in size of a small size, a medium size, and a large size;
each superior implant bone plate including a main bone plate body having an S-shape defining two opposing curved sections adapted for a superior surface of a clavicle wherein each of the opposing curved sections defines a radius with the one radius of the three bones plates ranging from 60 mm to 90 mm and the other radius of the three bone plates ranging from 83 mm to 100 mm;
a bendable waist portion narrower than the main body of the superior implant bone plate and located between the two opposing curved sections; and
a first node and a second node, with the first node at the end of one of the two opposing curved sections and the second noted at the end of the other of the two opposing curved sections;
wherein the three superior implant bone plates are configured and bendable so as to fit a range of clavicle radii of 39 mm to 130 mm.

11. The system of claim 10 , wherein each node is connected to the end of one of the two opposing curved sections of the main body by a bendable bridge portion which is narrower than the main body, and wherein the bendable bridge portion includes a cut-out relief portion on a bottom side of the superior implant bone plate.

12. The system of claim 10 further including two or more distal implant bone plates configured for a distal clavicle implant, each distal implant bone plate including a bendable waist.

13. The system of claim 12 , wherein an end of the distal implant bone plates include a plurality of additional nodes connected to a distal implant main body main body by bendable bridges, wherein each of the nodes include a conical surface on a bottom surface of the distal implant bone plates.

14. The system of claim 12 , further including one or more anterior/inferior implant bone plates, the one or more anterior/inferior implant bone plates being relatively straight compared to the distal implant bone plates.

15. The system of claim 14 , wherein each anterior/inferior implant bone plate includes an additional node at each end of a main body of the anterior/inferior implant bone plate, each additional node connected to the main body by a bridge.

16. The system of claim 15 , further including a bending iron configured to bend and shape the superior implant bone plates, the distal implant bone plates, and the one or more anterior/inferior implant bone plates; a modifying stick configured to bend and shape the superior implant bone plates by being inserted into a node of the bone plate, the distal implant bone plates, and the one or more anterior/inferior implant bone plates; and a plurality of fasteners configured to be received by a plurality of holes on the bone plate; wherein each of the superior implant bone plates, the distal implant bone plates, and the one or more anterior/inferior implant bone plates, the bending iron, the modifying stick, and the fasteners are located in a sterile container.
