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 bone stabilization plate comprising:
an elongate body extending from a beveled first end to a second end defining a length and extending from a first side to second side defining a width, wherein the elongate body has a top surface and an opposed bone contacting surface, the elongate body defining a series of aligned screw holes with a k-wire hole disposed between each aligned screw hole; and
a 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 width of the elongate body is constant, and
wherein each of the aligned screw holes 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 of each stacked hole 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.

2. The bone stabilization plate of claim 1 , wherein the thickness of each ring is equal to or less than a thickness of the elongate body.

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

4. A bone stabilization plate comprising:
an elongated body extending between a beveled first end and a second end and having an upper surface and an opposed bone contacting surface, the bone contacting surface having a scalloped configuration; and
a mesh head connected to the second end of the elongate body, the mesh head including a plurality of rings each 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 the elongated body defines a plurality of screw holes therethrough, wherein the screw holes are each configured and dimensioned to receive a screw, wherein each of the screw holes is aligned along a first axis,
wherein the elongated body defines a plurality of k-wire holes therethrough, wherein the k-wire holes are each configured and dimensioned to receive a k-wire, wherein each of the plurality of k-wire holes is aligned along the first axis, wherein each of the plurality of k-wire holes is disposed between two of the plurality of screw holes,
wherein each of the plurality of screw holes 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 of each stacked hole 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.

5. The bone stabilization plate of claim 4 , wherein each of the plurality of screw holes has a first diameter and each of the plurality of k-wire holes has a second diameter.

6. The bone stabilization plate of claim 5 , wherein the diameter of each of the plurality screw holes is larger than the diameter of each of the plurality of k-wire holes.
