Abstract

The present application provides new and innovative anterior clavicle plates and systems for clavicle fracture fixation. The provided anterior clavicle plate is shaped to better conform to or fit the anterior and lateral surfaces of a patient's clavicle as compared to typical anterior clavicle plates. This improved conformance can help reduce the incidence of tissue irritation, which reduces the chances of a second surgery being needed for removal of the anterior clavicle plate. The improved conformance can also result in an anatomically better fracture reduction than typical anterior clavicle plates and an increased fixation strength. Additionally, an instrument provided by the present application can help a surgeon install the provided anterior clavicle plate more quickly and with increased flexibility and consistency than typical systems.

First claim

The invention is claimed as follows:

1 . An anterior clavicle fracture fixation plate comprising:
a contoured body including a first end opposite a second end along a length of the contoured body, a superior side opposite an inferior side, and a plurality of openings along the length of the contoured body from the first end to the second end, each of the plurality of openings extending through a thickness of the contoured body from the superior side to the inferior side, wherein a plane extends through a first portion of the contoured body, the first portion being adjacent the first end, and a second portion of the contoured body curves away from the plane in a first direction, the second portion of the contoured body being adjacent the second end, wherein the contoured body includes a first bend along its length that bends at least partially in a second direction perpendicular to the first direction, wherein a height of the contoured body, measured perpendicular to the length, is greater at the first end than at the second end, wherein a cross-section of the contoured body is curved from the superior side to the inferior side, wherein, for at least a segment of the contoured body, a thickness of an inferior side portion of the contoured body is greater than a thickness of a superior side portion of the contoured body, the thickness measured perpendicular to the length of the contoured body, wherein the thickness of the superior side portion of the contoured body is greater at the first end than the second end, and wherein the plurality of openings comprises at least one opening at the first bend and angled with respect to the thickness of the contoured body at an angle that is different than a remainder of the plurality of openings, the at least one opening allowing a screw to be inserted through the at least one opening at a non-perpendicular angle relative to the thickness of the contoured body.

2 . The anterior clavicle fracture fixation plate of claim 1 , wherein the contoured body includes a second bend that bends at least partially in a third direction opposite the second direction.

3 . The anterior clavicle fracture fixation plate of claim 2 , wherein the first bend is closer to the second end than the second bend, and wherein the first bend has a larger degree of bend than the second bend.

4 . The anterior clavicle fracture fixation plate of claim 1 , wherein the height of the contoured body gradually decreases along its length.

5 . The anterior clavicle fracture fixation plate of claim 1 , wherein a first portion of the plurality of openings have greater respective diameters than a second portion of the plurality of openings, wherein the first portion of the plurality of openings are closer to the first end of the contoured body than the second portion of the plurality of openings.

6 . The anterior clavicle fracture fixation plate of claim 5 , wherein the respective diameters of the plurality of openings along the length of the contoured body decrease from the first end to the second end.

7 . The anterior clavicle fracture fixation plate of claim 1 , further comprising an arm extending from the contoured body, the arm configured to contact a superior surface of a clavicle while the contoured body contacts a lateral surface of the clavicle.

8 . The anterior clavicle fracture fixation plate of claim 7 , wherein the arm extends perpendicularly from the contoured body.

9 . The anterior clavicle fracture fixation plate of claim 7 , wherein a portion of the arm is substantially parallel to the second end of the contoured body.

10 . The anterior clavicle fracture fixation plate of claim 7 , wherein the arm includes a plate having a plurality of openings.

11 . The anterior clavicle fracture fixation plate of claim 1 , wherein the angle is acute or obtuse.

12 . The anterior clavicle fracture fixation plate of claim 1 , further comprising a guide for the at least one opening, the guide protruding from a surface of the contoured body surrounding the at least one opening to aid in inserting the screw concentrically in the at least one opening.

13 . A system for clavicle fracture fixation comprising:
an anterior clavicle fracture fixation plate including:
a contoured body including a first end opposite a second end along a length of the contoured body, a superior side opposite an inferior side, and a plurality of openings along the length of the contoured body from the first end to the second end, each of the plurality of openings extending through a thickness of the contoured body from the superior side to the inferior side,
wherein a plane extends through a first portion of the contoured body, the first portion being adjacent the first end, and a second portion of the contoured body curves away from the plane in a first direction, the second portion of the contoured body being adjacent the second end,
wherein the contoured body includes a first bend along its length that bends at least partially in a second direction perpendicular to the first direction,
wherein a height of the contoured body, measured perpendicular to the length, is greater at the first end than at the second end,
wherein a cross-section of the contoured body is curved from the superior side to the inferior side,
wherein, for at least a segment of the contoured body, a thickness of an inferior side portion of the contoured body is greater than a thickness of a superior side portion of the contoured body, the thickness measured perpendicular to the length of the contoured body,
wherein the thickness of the superior side portion of the contoured body is greater at the first end than the second end, and
wherein the plurality of openings comprises at least one opening at the first bend and angled with respect to the thickness of the contoured body at an angle that is different than a remainder of the plurality of openings, the at least one opening allowing a screw to be inserted through the at least one opening at a non-perpendicular angle relative to the thickness of the contoured body; and
an instrument configured to aid in insertion of one or more screws through openings of the anterior clavicle fracture fixation plate on an anterior surface of a clavicle.

14 . The system of claim 13 , wherein the instrument includes:
a base member configured to contact the anterior clavicle fracture fixation plate, a guide member including a slot and an elongate portion having a plurality of openings, and a locking post, wherein the locking post is positioned through the slot of the guide member and through the base member, thereby coupling the guide member and the base member.

15 . The system of claim 14 , wherein prior to engaging the locking post to the anterior clavicle fracture fixation plate, the guide member is rotatable about a long axis relative to the base member, and wherein subsequent to engaging the locking post to the anterior clavicle fracture fixation plate, the guide member is fixed relative to the base member.

16 . The system of claim 14 , wherein the guide member includes a first face configured to be adjacent to the anterior clavicle fracture fixation plate and a second face opposite the first face, and wherein the plurality of openings of the guide member include a greater cross sectional area at the second face than at the first face.

17 . The system of claim 13 , wherein the contoured body of the anterior clavicle fracture fixation plate is contoured such that it conforms to one of an anterior surface of a right side clavicle of a patient or an anterior
