Symmetrical bone plate
First Claim
1. A bone plate having a longitudinal axis and comprising first and second surfaces, a middle plane extending between the first and second surfaces and a plurality of plate holes extending from the first surface to the second surface for receiving a fastener, wherein the bone plate has an oval cross section and is configured and dimensioned to be substantially symmetrical about the middle plane, and wherein the first and second surfaces are concave along the longitudinal axis in an area between consecutive plate holes.

Abstract
The invention relates to a bone plate that has a longitudinal axis, top and bottom surfaces and plate holes which extend between the two surfaces for receiving bone screws or other fasteners. The bone plate is substantially symmetrical about a middle plane extending between the two surfaces. The symmetry of the bone plate makes it possible to set the bone plate on and fasten it to the bone with either surface facing the bone without affecting the clinical results.

11. A method for fixing a bone with a bone plate having first and second surfaces and at least one plate hole extending from the first surface to the second surface for receiving a fastener, the method comprising the steps of:
-
attaching the bone plate to a first portion of the bone such that the first surface of the bone plate faces the first portion of the bone; and
attaching the bone plate to a second portion of the bone such that the second surface of the bone plate faces the second portion of the bone, wherein the bone plate has an oval cross section and wherein the first and second surfaces are adapted and configured for contact with an external bone surface.

12. A method for fixing a bone having a cortex and a medullary canal with a bone plate having first and second surfaces and at least one plate hole extending from the first surface to the second surface for receiving a fastener, the method comprising the steps of:
-
inserting a first portion of the bone plate into the medullary canal of the bone; and
attaching a second portion of the bone plate to the cortex of the bone outside the medullary canal, wherein either the first or second surface of the second portion can face the cortex of the bone, and both the first and second portions of the bone plate have at least one plate hole for receiving a fastener.
