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 (7)

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, the elongate body comprising a top surface and an opposed bone contacting surface, the elongate body defining a plurality of aligned screw holes disposed therethrough along the length, each screw hole separated from an adjacent one of the screw holes by a k-wire hole and a side relief cut formed in both of the first and second sides of the elongate body; and a cluster head connected to the second end of the elongate body, the cluster head including a center hole and four extensions extending from the center hole with each extension including at least one hole, the four extensions defining an X configuration, wherein each k-wire hole has a smaller diameter than a diameter of each screw holes, and wherein at least one of the aligned screw holes of the elongate body and at least one of the holes of the four extensions 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.
2 . The bone stabilization plate of claim 1 , wherein two extensions of the four extensions extend in opposite directions from the center hole and a first imaginary line passes through a center of the center hole and the at least one hole of the two extensions.
3 . The bone stabilization plate of claim 2 , wherein the other two extensions of the four extensions extend in opposite directions from the center hole and a second imaginary line passes through a center of the center hole and the at least one hole of the other two extensions such that the first and second imaginary lines form an X and intersect each other at the center of the center hole.
4 . The bone stabilization plate of claim 1 , wherein the holes of the four extensions and the screw holes of the elongate body comprise any combination of stacked holes and locking holes, non-locking holes, and dynamic compression slots.
5 . The bone stabilization plate of claim 1 , wherein the holes of the four extensions and the screw holes of the elongate body comprise all stacked holes, a combination of stacked holes and combination holes, or a combination of stacked holes and dynamic compression plating (DCP) slots.
6 . The bone stabilization plate of claim 1 , wherein the holes of the four extensions and the screw holes of the elongate body all have the same configuration.
7 . The bone stabilization plate of claim 1 , wherein all of the holes of the four extensions and the screw holes of the elongate body all have the same diameter.

Description

CROSS REFERENCE TO RELATED APPLICATIONS The present application is a continuation of U.S. patent application Ser. No. 17/526,181, filed on Nov. 15, 2021, which is a continuation of U.S. patent application Ser. No. 15/893,774 filed on Feb. 12, 2018 (published as U.S. 2018-0161081), which is a continuation-in-part of U.S. patent application Ser. No. 15/405,368 filed Jan. 13, 2017 (now U.S. Pat. No. 10,751,098), which is a continuation-in-part of U.S. patent application Ser. No. 15/238,772, filed Aug. 17, 2016 (now U.S. Pat. No. 10,687,873), each of which is hereby incorporated by reference in its entirety for all purposes. FIELD The present disclosure relates to surgical devices, and more particularly, stabilization systems, for example, for trauma applications. BACKGROUND Bone fractures are often repaired by internal fixation of the bone, such as diaphyseal or methaphyseal bone, using one or more plates. The plate is held against the fractured bone with screws, for example, which engage the bone and heads which provide a compressive force against the plate. The plate and bone are thus forced against each other in a manner that transfers load primarily between a bone contacting surface of the plate and the bone surface to reinforce the fractured bone during healing. This manner of plating generally creates relatively low stress concentration in the bone, as there may be a large contact area between the plate and the bone surface permitting transfer of load to be dispersed. There may be a desire to use locking screws, non-locking screws, or a combination of both that are able to dynamically compress the bone. Of course, the designs of the plates, types of screws, and locking and/or non-locking capabilities may vary based on the location and type of fracture. Thus, there is a need for plating systems that provide stabilization to the appropriate anatomical area while providing appropriate locking and/or unlocking capability for dynamic compression of the bone. SUMMARY To meet this and other needs, devices, systems, and methods of bone stabilization are provided. The stabilization systems may include one or more plates and one or more fasteners. The fasteners may include locking and/or non-locking bone screws that a surgeon may select based on preference for a specific anatomical case. The locking fasteners may connect to the plate and the bone to thereby lock the plate to the bone. The non-locking fasteners may be able to dynamically compress the bone and create interfragmental compression. According to one embodiment, a stabilization system includes a bone plate and a fastener. The bone plate has an upper surface and a lower surface configured to be in contact with bone, the bone plate having an opening extending from the upper surface to the lower surface. The opening includes a textured portion and non-textured portion, wherein the textured portion comprises a texture that is a non-threaded surface. The fastener is configured to be received by the opening and configured to be inserted into the bone. The opening is configured to receive either a locking fastener or a compression fastener. The locking fastener may have a threaded head portion configured to engage the textured portion and lock to the bone plate, and the compression fastener may have a substantially smooth head portion configured to dynamically compress the bone. The opening may include a combination compression and locking through hole formed by a first bore having a first bore axis and a second bore having a second bore axis different from the first bore axis. In some instances, one of the first and second bores may have an elongated opening, for example, to allow for translation of the non-locking, compression fastener. According to another embodiment, a stabilization system includes a bone plate, a locking fastener, and a compression fastener. The bone plate has an upper surface and a lower surface configured to be in contact with bone, the bone plate having an opening extending from the upper surface to the lower surface, the opening including a textured portion and non-textured portion, wherein the textured portion comprises a texture that is a non-threaded surface. The locking fastener is configured to be received by one of the openings and configured to be inserted into the bone, wherein the locking fastener has a threaded head portion configured to lock to the bone plate. The compression fastener is configured to be received by one of the openings and configured to be inserted into the bone, wherein the compression fastener has a substantially smooth head portion configured to dynamically compress the bone. Each opening is configured to receive either the locking fastener or the compression fastener. According to yet another embodiment, a stabilization system includes a bone plate and a fastener. The bone plate has an upper surface and a lower surface configured to be in contact with bone, the bone plate having an opening extending from
