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.

First claim

What is claimed is:

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.
