ROTATIONAL OSTEOTOMY PLATING SYSTEM

1 . An apparatus for repairing a bone comprising:

a first plate adapted and configured for attachment to a long bone of an animal, said first plate having at least one hole for receiving a bone anchoring device therethrough;

a second plate adapted and configured for attachment to a long bone of an animal, said second plate having at least one hole for receiving a bone anchoring device therethrough;

a third plate having an upper portion for coupling to said first plate and a lower portion for coupling to said second plate, the upper portion having an angular offset relative to the lower portion in a first direction about a longitudinal axis of the bone.

2 . The apparatus of claim 1 wherein the upper portion has a first thickness, the lower portion has a second thickness, and the first thickness is different than the second thickness.

3 . The apparatus of claim 1 wherein the upper portion has an angular offset relative to the lower portion in a second direction about a second axis that is at least partly orthogonal to the longitudinal axis.

4 . The apparatus of claim 1 wherein said third plate include a through hole for accepting a first fastener therethrough and said first plate includes a threaded hole for threadably accepting the first fastener

5 . The apparatus of claim 4 wherein said third plate include a through hole for accepting a bone anchor therethrough, and said through hole of said third plate aligning with said at least one hole of said second plate, wherein said through hole and said at least one hole are capable of accepting the same bone anchor.

6 . The apparatus of claim 1 which further comprises a spacer for insertion between said third plate and said first plate.

7 . The apparatus of claim 1 wherein said first plate is curved about an axis that is generally parallel to the longitudinal axis of the bone.

8 . The apparatus of claim 7 wherein said second plate is curved about the longitudinal axis of the bone.

9 . The apparatus of claim 7 wherein the upper portion has an angular offset relative to the lower portion in a second direction about a second axis that is at least partly orthogonal to the longitudinal axis.

10 . A method for repairing a bone, comprising:

providing two primary plates and a secondary plate;

fastening the first and second primary plates to the bone, one plate being fastened above the other plate, the plates being spaced apart from each other;

cutting through the bone between the plates;

rotating the two portions of the bone relative to each other to establish an angular relationship of the one bone portion relative to the other bone portion;

fastening the secondary plate to one of the first primary plate or the bone proximate to the first primary plate; and

fastening the secondary plate to one of the second primary plate or the bone proximate to the second primary plate.

11 . The method of claim 10 wherein said fastening the secondary plate to one of the first primary plate or the bone proximate to the first primary plate is by fastening the secondary plate to the first primary plate.

12 . The method of claim 11 wherein said fastening the secondary plate to one of the second primary plate or the bone proximate to the second primary plate is by fastening the secondary plate to the bone proximate to the second primary plate, the undersurface of the secondary plate being at least partly in contact with the second primary plate.

13 . The method of claim 10 wherein said fastening the secondary plate to one of the first primary plate or the bone proximate to the first primary plate is by fastening the secondary plate to the bone proximate to the first primary plate, the undersurface of the secondary plate being at least partly in contact with the first primary plate.

14 . The method of claim 13 wherein said fastening the secondary plate to one of the second primary plate or the bone proximate to the second primary plate is by fastening the secondary plate to the second primary plate.

15 . An orthopedic kit for a bone, comprising:

at least two primary plates adapted and configured for attachment to a bone, each said primary plate having at least one hole for receiving a bone anchoring device therethrough; and

at least two secondary plates each adapted and configured for attachment to two primary plates, each said secondary plate having at least two holes for receiving fasteners therethrough for attachment of a said secondary plate to two said primary plates, each secondary plate being curved about a longitudinal axis of the bone, the curvature of one said secondary plate being different than the curvature of the other said secondary plate.

16 . The kit of claim 15 which further comprises a plurality of spacers, each spacer having a different thickness than each other spacer, each spacer having at least one through hole.

17 . The kit of claim 15 wherein the curvature is a first curvature, and each secondary plate having a second curvature about a second axis, the second axis being at least partly orthogonal to the longitudinal axis, the second curvature of one said secondary plate being different than the curvature of the other said secondary plate.

18 . The kit of claim 17 wherein each said primary plate is curved about an axis that is generally parallel to the longitudinal axis of the bone.
