Abstract

Clavicle fixation devices and methods thereof. A clavicle fixation device includes an elongated plate extending between first and second ends, the elongated plate defining a plurality of spaced apart screw holes. At least one pair of relief cuts extends into the elongated plate on opposite sides thereof, the at least one pair of relief cuts axially positioned between a pair of the spaced apart screw holes and at least one pair of suture holes along opposite sides of the elongated plate, the at least one pair of suture holes axially positioned between a pair of the spaced apart screw holes. At least one pair of relief cuts is axially aligned with a pair of suture holes to define combined holes on opposite sides of the elongated plate.

First claim

What is claimed is:

1. A clavicle fixation system comprising:
an intramedullary clavicle nail having an elongated body extending from a trailing end to a medial, leading end,
wherein the leading end of the nail has a pointed shape with flats on each side of a rounded tip and the rounded tip extends to a wide underside; and
an elongated plate extending between first and second ends and defining a central portion, a first end portion between the central portion and the first end, and a second end portion between the central portion and the second end, the elongated plate defining a plurality of spaced apart screw holes,
wherein at least one pair of relief cuts extends into the elongated plate on opposite sides thereof, the at least one pair of relief cuts axially positioned between a pair of the spaced apart screw holes and at least one pair of suture holes along opposite sides of the elongated plate, the at least one pair of suture holes positioned between a pair of the spaced apart screw holes.

2. The clavicle fixation system according to claim 1 wherein an undercut in an inner surface of the elongated plate is aligned with each suture hole.

3. The clavicle fixation system according to claim 2 wherein at least a portion of the undercuts have a width larger than a width of the corresponding suture hole.

4. The clavicle fixation system according to claim 1 wherein at least one pair of relief cuts is axially aligned with a pair of suture holes to define combined holes on opposite sides of the elongated plate.

5. The clavicle fixation system according to claim 4 wherein the central portion is sized such that the central portion is configured to overly a common clavicle fracture zone which is determined based on image research study of clavicle fractures.

6. The clavicle fixation system according to claim 1 wherein a plurality of combined hole pairs are defined along the elongated plate.

7. The clavicle fixation system according to claim 1 wherein the elongated plate has an initial contour configured to complement a contour of a clavicle anterior or superior surface.

8. The clavicle fixation system according to claim 1 wherein the elongated plate has an initial unbent flat contour.

9. The clavicle fixation system according to claim 1 wherein the second end portion narrows moving from the central portion to the second end.

10. The clavicle fixation system according to claim 1 wherein the first end portion narrows at at least two different angles, with a first subportion closer to the central portion narrowing at a steeper angle than a second subportion closer to the first end.

11. The clavicle fixation system according to claim 1 wherein each of the end portions tapers from a maximum thickness adjacent a central portion to a reduced thickness adjacent the respective end.

12. The clavicle fixation system according to claim 1 wherein the elongated plate defines an outer surface and an inner surface and at least the inner surface has a rounded configuration.

13. The clavicle fixation system according to claim 12 wherein at least one elongated undercut is defined along the inner surface extending between the first and second ends, the elongated undercut having a radial or elliptical dimension smaller than a radial or elliptical dimension of the inner surface.

14. The clavicle fixation system according to claim 12 wherein at least two elongated undercuts are defined along the inner surface extending between the first and second ends, each elongated undercut having a radial or elliptical dimension smaller than a radial or elliptical dimension of the inner surface.

15. The clavicle fixation system according to claim 1 wherein the screw holes include polyaxial holes and dynamic compression plating slots.

16. A clavicle fixation system comprising:
an elongated plate extending between first and second ends, the elongated plate defining a plurality of spaced apart screw holes,
an intramedullary clavicle nail having an elongated body extending from a trailing end to a medial, leading end;
wherein the leading end of the nail has a pointed shape with flats on each side of a rounded tip and the rounded tip extends to a wide underside;
wherein at least one pair of relief cuts extends into the elongated plate on opposite sides thereof, the at least one pair of relief cuts axially positioned between a pair of the spaced apart screw holes and at least one pair of suture holes along opposite sides of the elongated plate, the at least one pair of suture holes axially positioned between a pair of the spaced apart screw holes; and
wherein at least one pair of relief cuts is axially aligned with a pair of suture holes to define combined holes on opposite sides of the elongated plate.

17. The clavicle fixation system according to claim 16 wherein an undercut in an inner surface of the elongated plate is aligned with each suture hole and forms a portion of a combined hole.

18. The clavicle fixation system according to claim 16 wherein the elongated plate has an initial unbent flat contour.

19. The clavicle fixation system according to claim 16 wherein a portion of the elongated plate between a relief cut and a suture hole of a combined hole is configured to stretch and straighten when a sufficient tension force is applied to the elongated plate proximate the combined hole.

20. The clavicle fixation system according to claim 16 , wherein the wide underside of the intramedullary clavicle nail is configured to provide rotational stability to maintain an orientation of the nail with a restored anterior bone curvature.
