Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bone plate assembly having a tension means and a method of assembling the bone plate, and more particularly, to a bone plate assembly having a tension plate And a method of assembling the bone plate assembly.
Bone plates are fastening means used to fix bone fragments inside human and animal bodies. These bone plates are placed across the bone fragments and support, and the fractured bone is secured by securing each bone fragment and support and bone plate through bone screws.
Since the bone fragments in the human body or animal body have various shapes, in order to firmly connect the bone fragments with the support, it is necessary to be able to arrange the bone screws of various sizes, not one standard, on the bone plate at various angles.
However, existing bone plates all have a problem in that it is difficult to fasten bone screws of various sizes on a bone plate at a set angle by forming a screw thread arbitrarily.
Therefore, there is a disadvantage in that it is not easy to effectively and stably fracture the fractured bone using the bone plate.
It is an object of the present invention to provide a bone plate assembly and a method for assembling a bone plate to a fractured bone having tension means capable of fastening bone screws of various sizes at a set angle.
The present invention relates to a bone plate assembly for use in reinforcing a fractured bone, the bone plate assembly comprising: a plate-shaped bone plate having a plurality of through holes formed in the inner wall thereof; And a bone screw having a head portion of a predetermined shape and fastened to the through hole through reverse rotation or normal rotation, wherein the inner wall of the through hole of the bone plate has a plurality of incisions and protrusions, There is provided a bone plate assembly which is alternately formed along a circumferential direction and has a tensioning means for imparting a tension corresponding to a fastening direction to a bone screw fastened to the bone plate.
Further, the bone plate may be formed so that the through holes are rounded or tapered from above to below.
In addition, the bone plate may be threaded from at least a portion of the first region, which is the initial region of the through hole, to a second region below the initial region, and the screw may be fastened to the through region through the first region and the second region have.
Also, at least one of the through holes of the bone plate is formed such that the threads on the first and second regions are inclined at a predetermined angle of inclination, and the bone screws correspond to the inclined threads on the first region and the second region And the head part can be fastened by pressing the incision part and the protruding part according to the inclination of the bone screw.
In addition, the cutout on the first region may be formed to overlap the thread pitch and block the thread pitch.
According to another aspect of the present invention, there is provided a method of assembling a bone plate assembly for use in reinforcing a fractured bone, comprising the steps of: preparing a plate-shaped bone plate having a plurality of through- ; And a second step of preparing a bone screw having a head portion of a predetermined shape and being fastened to the through hole through reverse rotation or normal rotation, wherein the first step is a step of supporting a bone screw fastened to the bone plate And a first-stage step of forming a plurality of cut-outs and protrusions alternately along the circumferential direction at a predetermined depth toward the inner wall, on the inner wall of the through-hole of the bone plate so as to impart tension to the bone plate. The present invention provides a bone plate assembly assembly method.
Further, the bone plate may be formed so that the through holes are rounded or tapered from above to below.
And a second step of causing the bone plate to form a thread over at least a portion of the first region, which is an initial portion of the through hole, over the second region of the initial region, and the second step includes: 1 region and the second region, respectively.
The first step further includes a 1-3 step of forming at least one of the through holes of the bone plate so that the threads on the first area and the second area are inclined at a predetermined angle of inclination, Wherein the head portion is a step of pressing the incision portion and the protrusion portion in accordance with the inclination of the bone screw, .
In addition, the cutout on the first region may be formed to overlap the thread pitch and block the thread pitch.
The bone plate assembly having the tensioning means according to the present invention and the method of assembling the same have the effect of fastening bone screws of various sizes, rather than a bone screw of a single size, on the bone plate with a set angle.
