Abstract

Devices, systems, and methods of bone stabilization. The bone stabilization system includes a mesh body. The mesh body includes a plurality of rings, with each of the rings defining a screw hole. Bridge portions extend between and interconnect the rings. The bridge portions have a reduced thickness compared to the rings. An elongate body may also extend from the mesh body. The elongate body defines at least one screw hole.

Claims (22)

1. A method for stabilizing a bone, said method comprising:

providing a bone stabilization plate, the bone stabilization plate including:

an elongate body extending from a beveled first end to a second end defining a length and extending from a first side to a second side defining a width, the elongate body comprising a top surface and an opposed bone contacting surface, the elongate body comprising a plurality of aligned screw holes with a k-wire hole disposed between each of the aligned screw holes; and

an elongated mesh head connected to the second end of the elongate body, the mesh head including a plurality of rings, with each of the rings defining a screw hole, and bridge portions extending between and interconnecting the rings, the bridge portions having a reduced thickness compared to a thickness of the rings, wherein through spaces extend between respective groups of the rings,

wherein the bridge portion between two adjacent rings comprises an elongate groove which extends perpendicular to a central axis extending through a center of the two adjacent rings,

wherein at least one of the aligned screw holes of the elongate body is a stacked hole configured to receive a locking fastener or a non-locking fastener, each stacked hole including a textured portion, an upper conical chamfer on top of the textured portion and a lower conical chamfer below the textured portion, wherein the lower conical chamfer has a greater diameter than both the upper conical chamfer and the textured portion, and wherein the textured portion is configured to deform when a head of the locking fastener is inserted therein, thereby providing a positive lock between the locking fastener and the elongate body;

contouring the bone stabilization plate to a desired shape; and

fixating the bone stabilization plate to the bone by inserting a locking fastener or a non-locking fastener through at least some of the plurality of aligned screw holes of the elongate body and the screw holes of the mesh head.

2. The method of claim 1 , wherein the rings have a thickness which is equal to or less than a thickness of the elongate body.

3. The method of claim 1 , wherein the rings are arranged in rows such that the mesh head has a square or rectangular configuration.

4. The method of claim 1 , wherein the at plurality of aligned screw holes comprise locking holes, non-locking holes, combination holes, stacked holes, and dynamic compression slots, or a combination thereof.

5. The method of claim 1 , wherein each of the plurality of aligned screw holes has the same configuration.

6. The method of claim 1 , wherein the bone contacting surface is scalloped.

7. The method of claim 1 , wherein disposed among respective groups of the rings and both ends of at least some of the elongate grooves terminate at some of the through spaces.

8. A method for stabilizing a bone, said method comprising:

providing a bone stabilization plate according to claim 1 ;

contouring the bone stabilization plate to a desired shape; and

fixating the bone stabilization plate to the bone by inserting a locking fastener or a non-locking fastener through at least some of the plurality of aligned screw holes of the elongate body and the screw holes of the mesh head.

9. The method of claim 8 , wherein the rings are arranged in rows such that the mesh head has a square or rectangular configuration.

10. The method of claim 8 , wherein the plurality of aligned screw holes comprise locking holes, non-locking holes, combination holes, stacked holes, dynamic compression slots, or a combination thereof.

11. The method of claim 8 , wherein each of the plurality of aligned screw holes has the same configuration.

12. The method of claim 8 , wherein both ends of at least some of the elongate grooves terminate at some of the through spaces.
