Sternum fixation devices and methods

1. An apparatus for sternum fixation, comprising:

a plate comprising a first end and a second end, a right lateral edge and a left lateral edge, an inner side configured for placement against the sternum, and an outer side configured to face away from the sternum;

a first lobe disposed on the plate at the first end, the first lobe including a band socket defined as a blind recess in the outer side of the plate, the band socket including a right lateral stop and a left lateral stop opposite the right lateral stop;

a right lateral channel defined in the first lobe from the right lateral edge to the band socket, the right lateral channel defined above a right side floor in the socket; and

a left lateral channel opposite the right lateral channel defined in the first lobe from the left lateral edge to the band socket, the left lateral channel defined above a left floor in the socket,

wherein the left lateral stop protrudes from the left lateral channel inwardly into the socket at an inclined angle above the left floor forming a wedge-shaped recess in the socket, and

wherein the right lateral stop comprises first and second tapered walls extending upwardly from the right floor in the socket toward the right lateral channel.

2. The apparatus of claim 1 , further comprising:

a second lobe disposed on the plate longitudinally spaced from the first lobe; and

a first bridge disposed between the first lobe and the second lobe.

3. The apparatus of claim 2 , further comprising a first clearance hole defined through the plate on the first bridge between the first and second lobes.

4. The apparatus of claim 3 , further comprising a second band socket defined in the second lobe as a blind recess in the outer side of the plate.

5. The apparatus of claim 4 , further comprising:

a third lobe disposed on the plate longitudinally spaced from the first and second lobes; and

a second bridge disposed between the second lobe and the third lobe.

6. The apparatus of claim 5 , further comprising a second clearance hole defined through the plate on the second bridge between the second and third lobes.

7. The apparatus of claim 6 , further comprising a third band socket defined in the third lobe as a blind recess in the outer side of the plate.

8. The apparatus of claim 7 , further comprising:

a fourth lobe disposed on the plate longitudinally spaced from the first, second and third lobes; and

a third bridge disposed between the third lobe and the fourth lobe.

9. The apparatus of claim 8 , further comprising a third clearance hole defined through the plate on the third bridge between the third and fourth lobes.

10. The apparatus of claim 9 , further comprising a fourth band socket defined in the fourth lobe as a blind recess in the outer side of the plate.

11. The apparatus of claim 10 , further comprising:

a fifth lobe disposed on the plate longitudinally spaced from the first, second, third and fourth lobes; and

a fourth bridge disposed between the fourth lobe and the fifth lobe.

12. The apparatus of claim 11 , further comprising a fourth clearance hole defined through the plate on the fourth bridge between the fourth and fifth lobes.

13. The apparatus of claim 12 , further comprising a fifth band socket defined in the fifth lobe as a blind recess in the outer side of the plate.

14. The apparatus of claim 13 , further comprising a fastener band disposed on the plate, the fastener band including a head disposed in the first band socket and a strap extending from the head out of the right lateral channel away from the plate.

15. The apparatus of claim 14 , wherein the strap is configured to extend around the sternum, through the right left lateral channel into the head disposed in the socket.

16. The apparatus of claim 15 , further comprising:

an arcuate recess defined on the inner side of the plate between the first and second lobes.

17. The apparatus of claim 16 , further comprising a living hinge formed in the first bridge adjacent the arcuate recess configured to allow the first lobe to flex inwardly relative to the second lobe to accommodate the curvature of the sternum toward a manubrium of the sternum.
