Abstract

A medial plate for treating fractures along a clavicle, comprising a plate body including a longitudinal component extending from a first end to a second end and an extension extending from the second end, the second end configured to be mounted over a medial head, a first set of variable angle holes extending through a portion of the longitudinal component including the second end of the longitudinal component and the extension, each of the first set of variable angle holes extending through the plate body along a central axis so that a bone screw is insertable therethrough at a user-selected angle relative to the central axis, and a plurality of combination holes extending through the longitudinal component, each of the plurality of combination holes includes a first portion configured to receive a bone screw at a user-selected angle and a second portion configured to receive a compression screw.

First claim

What is claimed is:

1. A medial plate for treating medial fractures of a clavicle, comprising:
a plate body sized and shaped to be positioned along a medial portion of a clavicle bone, the plate body including a longitudinal component extending from a first end to a second end along a longitudinal axis and an extension extending from the second end, away from the longitudinal axis, the second end configured to be mounted over a medial head of a clavicle bone, the plate body defined via an upper surface which, in an operative position, faces away from the clavicle bone, and a lower surface which, in the operative position, faces toward the clavicle bone;
a first set of screw holes extending through a portion of the longitudinal component including the second end of the longitudinal component and the extension, each of the first set of screw holes extends through the plate body from the upper surface to the lower surface along a central axis so that a bone screw is insertable therethrough; and
a plurality of combination holes extending through the longitudinal component, the combination holes being located on a portion of the plate which, when mounted on a bone, are located laterally of the first set of screw holes, each of the combination holes including a first portion configured to receive a locking bone screw and a second portion configured to receive a non-locking screw therein.

2. The medial plate of claim 1 , wherein the plate body is sized and shaped so that, in the operative position, the second end of the longitudinal component is configured to extend over an anterior surface of a medial end of a clavicle and a length of the longitudinal component extends toward a superior surface of the clavicle.

3. The medial plate of claim 1 , wherein the first end of the longitudinal component is rotated about the longitudinal axis relative to the second end of the longitudinal component.

4. The medial plate of claim 1 , wherein one of the first and second ends includes an angled surface connecting the upper surface to the lower surface to form a low profile for facilitating insertion.

5. The medial plate of claim 1 , wherein the extension extends away from the longitudinal axis so that, in the operative position, the extension extends toward the superior surface of the clavicle.

6. The medial plate of claim 1 , wherein a portion of the plate body extending between the extension and the longitudinal component includes a groove extending therealong so that the extension is bendable relative to the longitudinal component along the groove.

7. The medial plate of claim 1 , wherein the first set of screw holes extend along a medial edge of the medial plate and are aligned relative to one another.

8. The medial plate of claim 7 , wherein the first set of screw holes include variable angle holes so that bone screws are insertable therethrough at user-selected angles relative to the central axes of the first set of variable angle holes.

9. The medial plate of claim 1 , further comprising a second set of screw holes extending through a portion of the longitudinal component including the first end, each of the second set of screw holes extending through the longitudinal component from the upper surface to the lower surface along a central axis such that a bone screw is insertable therethrough.

10. The medial plate of claim 9 , wherein each of the second set of screw holes are staggered relative to one another about the longitudinal axis.

11. The medial plate of claim 9 , wherein the second set of screw holes include variable angle holes so that bone screws are insertable therethrough at user-selected angles relative to the central axes of the second set of variable angle holes.

12. The medial plate of claim 9 , further comprising a bending zone configured to facilitate bending of the plate body along a portion of the plate body between the first set of screw holes and the second set of screw holes.

13. The medial plate of claim 12 , wherein the bending zone is defined via recesses extending into longitudinal sides of the longitudinal component to form a reduced width portion of the plate body.
