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 (18)

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.
