Embodiment Construction

[0029] The present invention relates to a device for processing fractures, and in particular to an internal fixing device for processing fractures. The invention can be further understood with reference to the following description and drawings. The exemplary embodiments of the present invention describe an improved bone fixation assembly that allows the surgeon to select the angle of the bone screw relative to the plate in a single action. The assembly uses only two parts and does not require any rings, bushings or expansion screws. Those skilled in the art can understand that although the example embodiments are described with respect to screws / pins and plates, the device may use any known fixing member to fix the break.

[0030] As in Figure 1-Figure 10 As shown in, the device 100 according to the first example embodiment of the present invention includes a screw or pin 102 and a plate 104. Such as figure 1 As shown in, the plate 104 includes at least one hole 106 that recei...

Abstract

A plate for fixation to a target portion of bone to be treated, comprises a first fixation element receiving opening extending therethrough from a proximal surface to a distal surface, the first fixation element receiving opening including a plurality of columns distributed about a circumference thereof and a plurality of radially expanded sections separating adjacent ones of the columns from one another in combination with a plurality of projections formed on the columns, the projections extending from surfaces of the columns, shapes of the surfaces of the columns on which the projections are formed being selected so that, when engaged by a head of a bone fixation element, the projections engage a thread of a head of the bone fixation element to lock the bone fixation element in the first fixation element receiving opening at any user selected angle within a permitted range of angulation.

Description

[0001] Priority statement [0002] This application claims the priority of the following applications: (1) U.S. Provisional Application No. 61 / 000,907 entitled "Variable Angle Locked Bone Plate" filed on October 30, 2007, and (2) U.S. Provisional Application No. 61 / 084,281 filed on July 29, 2008, entitled "Variable Angle Locked Bone Plate". The specification of the aforementioned application is incorporated herein by reference. Background technique [0003] The present invention relates to locking bone fixation components, and in particular to components that allow the surgeon to select the angle of the bone screw relative to the fixation device. [0004] Fasteners such as screws, bolts, or pins are often used to couple internal and external orthopedic fixation devices to the bone. For example, the bone plate can be fastened to the bone by a bone screw inserted through the plate hole. Fastening the screw to the plate provides a fixed angular relationship between the plate and the ...
