Problems solved by technology

As in the case of the prior art mentioned above, this appears to be a disadvantage of the tensioning element in question, that is, after the fixation tool is pushed through the adjoining tensioning element and its subsequent insertion into the fracture site Previously, the connected tensioning elements could not be firmly positioned relative to each other

Embodiment Construction

[0069] The mode of operation of the fixture 100 is in Figure 8A and 8B Before being described in , individual components will be described first.

[0070] figure 1 It is a perspective view of the first embodiment of the tensioning element 2 of the present invention, Figure 2A For top view. The tensioning element 2 consists of a corrugated body which is hollow when viewed from above and which has a peripheral wall 4 . The tensioning element 2 furthermore comprises two front-side receiving sections 6 a and 6 b , said 6 a and 6 b facing each other, and two lateral sides with a bow-shaped section 8 . The two front-side receiving sections 6 a and 6 b lie in relation to the transverse axis Q of the tensioning element 2 S face each other and have an outward curvature. The two arcuate sections 8 lie opposite each other with respect to the longitudinal axis LS of the tensioning element 2 and have an outward curvature. figure 1 The tensioning element 2 shown forms a generally r...

Abstract

The invention proposes a fixing device for fixing the fracture ends of bones in a bone fracture comprising at least two tensioning elements (2a, 2b), each of which has a contoured body that is hollow when viewed from above, has a circumferential wall (4) and two face sided receiving sections (6a, 6b) lying opposite to each other, at least one clamping sleeve and at least two fixing means which can be position in the face sided receiving sections. The at least two tensioning elements (2a, 2b) are positioned in relation to each other in such a way that one receiving section (6a, 6b) of each tensioning element (2a, 2b) is aligned with the respective other receiving section and are penetrated by the clamping sleeve in such a way that both tensioning elements (2a, 2b) are coupled to each other. According to invention the clamping sleeve furthermore is an angle clamping sleeve (15) which is connected with the at least two tensioning elements (2a, 2b) in such a way that the latter lie in a predetermined angular position in relation to each other.

Description

technical field [0001] The present invention relates to a fixation device for fixing bone stumps in fractures as claimed in claim 1, as well as to a tensioning element used thereby as claimed in claim 23 and to a tensioning element used thereby as claimed in claim 25. Angle clamping sleeve. The invention also relates to a method for fixing bone stumps in fractures as claimed in claim 27 . Background technique [0002] When the fracture is not adequately immobilized, callus morphology, such as callus-like thickening of the fracture tip from overgrown bone tissue, may occur. In order to avoid such indirect fracture healing by callousing, bone plates are used, which are applied and attached to the outer surface of the broken bone so that the position of the fracture is shaped, eg fixed, during the healing process. [0003] In addition, when compressive forces act on the fracture's seam site, this favorably affects the healing process of the fracture. In this way, a special f...
