Abstract

Bone plate systems, resection guides, implants, and methods are disclosed. A bone plate system may include a plate including a plurality of openings and a resection guide. A plate may include a body with a first end and a second end, at least two openings in the body, a first opening positioned in the first end and a second opening positioned in the second end, and an alignment marking disposed on a surface of the body. A guide may include a body with a first end and a second end, at least one first opening in the first end of the body, and at least one second opening in the second end of the body. Surgical methods for using the bone plate system, resection guides, and implants are also disclosed.

First claim

Having thus described the preferred embodiments, the invention is now claimed to be:

1. A bone plate system, comprising:
a plate including a plurality of plate openings to receive fasteners to connect the plate to a bone;
a resection guide having a first locator opening for receiving a wire to connect the guide to the bone and a second locator opening for receiving a second wire to connect the guide to the bone, and a plurality of holes for receiving at least a third wire to create a plurality of openings in the bone, the plurality of openings providing a guide for a cutting tool to resect the bone;
the resection guide comprising:
a body with a first end and a second end;
the first locator opening in the first end of the body;
the second locator opening in the second end of the body;
a first extension portion extending away from a first side near the first end;
a second extension portion extending away from a second side near a middle of the body;
a first hole of the plurality of holes positioned in the first extension portion;
a second hole of the plurality of holes positioned adjacent to the first locator opening;
the second locator opening positioned at the second end near a first side;
a third hole of the plurality of holes positioned in the second extension; and

the plate comprising a first plate portion at a first end of the plate and a second plate portion at a second end of the plate, the first plate portion and the second plate angled relative to each other to provide a correction to a profile of the bone.

2. The bone plate system of claim 1 , wherein the plate comprises:
a body with a first end and a second end;
a first plate opening of the plurality of plate openings positioned in the first end and a second plate opening of the plurality of plate openings positioned in the second end; and
an alignment marking disposed on a surface of the body for alignment with an osteotomy surface of the bone.

3. The bone plate system of claim 2 , wherein the plate further comprises:
a first tab extending away from a first side near a center of the body; and
a second tab extending away from a second side near a center of the body.

4. The bone plate system of claim 3 , wherein the plate further comprises:
a first hole positioned in the first tab;
a second hole positioned in the second tab; and
a third hole positioned between the first hole and the second hole and along an axis extending between the first hole and the second hole.

5. The bone plate system of claim 2 , wherein the alignment marking is positioned along a longitudinal axis of the body and wherein the longitudinal axis extends between the first end and the second end.

6. The bone plate system of claim 2 , wherein the plate further comprises:
at least one wire guide positioned within at least one of the first plate opening, the first hole, the second hole, and the third hole; and
a bushing coupled to the second plate opening.

7. The bone plate system of claim 1 , wherein the plate is angled along the longitudinal axis such that a longitudinal axis of said first plate portion and a longitudinal axis of said second plate portion are angled relative to each other longitudinally to provide a concave bottom surface for contacting the bone.

8. The bone plate system of claim 1 , wherein the plate is nonlinear in the transverse plane.

9. The bone plate system of claim 1 , wherein the resection guide is made of a transparent material.
