Problems solved by technology

However, this known plate cannot be readjusted (reshaped) during surgery due to its very rigid structural form
[0005] In this case, if there are dorsal and / or radial fragment areas, then with the plates according to the prior art it is not always possible to fix all the fragments perfectly after repositioning, which is a further disadvantage

Embodiment Construction

[0024] As can be seen in the figure, the distal radial plates each have a slender shaft 1, which has a combination of screw holes 2 and elongated holes 3, with or without tapered threaded holes. . In the transition region between the elongated hole 3 and the subsequent screw hole 2 there is a symmetrical recess 4 in the form of a waist on the shaft.

[0025] A bend 6 is provided in the transition region of the shaft 1 to the distal plate 5 so that the desired anatomically appropriate basic structure is formed.

[0026] As can be seen, the cross-section of the shaft 1 has an arch which helps to protect the periosteum from stinging (irritation).

[0027] in press figure 1 In the form of implementation, it is based on the non-equilateral triangular shape of the plate 5.

[0028] The side of the triangle facing away from the shank 1 , ie the side 8 , has a number of conical threaded holes 9 with a smaller diameter than the screw holes 2 in the shank 1 .

[0029] The distributi...

Abstract

The invention relates to a plate for stabilizing distal radius fractures, comprising an elongated stem (1) and anatomically pre-shaped distal plate (5) connected to it, wherein the plate The envelope has a substantially triangular shape; it also includes threaded holes provided in the stem and in the distal plate, at least on the distal plate, in a tapered configuration with a threaded longitudinal axis, each threaded longitudinal axis at The distal plate is mainly distributed non-parallel and a bend (6) is formed between the stem and the plate. According to the invention, the triangular shape of the plate or the corresponding envelope is scalene, wherein the side of the triangle facing away from the shaft has a number of conical threaded holes. The diameter of these tapered threaded holes is chosen to be smaller than the diameter of the screw holes in the shank, and the longitudinal axes of the threads of the plurality of holes in the plate form an angle different from 90° to the surface of the shank.

Description

technical field [0001] The present invention relates to a plate for stabilizing distal radius fractures. Background technique [0002] A distal radius fracture is the most common bone injury people experience as a split in the portion of the radius near the hand joint, mostly from a fall into an outstretched or bent hand. The radius dehisces mainly near the hand joint with or without the articular surface. Severe injuries with fractures of the articular surface itself mostly occur when the hand joint is axially stressed, which in extreme cases fractures the radius into many pieces. This kind of fracture often occurs in patients who perform sports such as inline skating, motorcycle riding, and skiing. [0003] Indications for surgery depend on fracture type and degree of dislocation. Volar flexions or Smith fractures (Volar-Flexions-oder Smith-Frakturen) are always unstable and are an indication for a corresponding volar bearing plate-osteosynthesis (Abstützplatten-Osteosy...
