System for setting tubular bone fractures
First Claim
1. Setting device for tubular bone fractures, said device comprising:
- A) a longitudinally extended flattened setting element comprised of tissue-compatible, high-density material, said setting element having;
1) a cross-section which is essentially rectangular;
2) rigid end sections, each having at least two bores extending through opposite wide sides thereof for guiding bone screws having a shaft through said end sections; and
,3) a connection section extending between said rigid end sections, said connection section having a cross-section smaller than the cross-section of the end sections,B) means for positioning said setting element on the said bone screws in a spaced, non-contacting relationship with the surface of the tubular bone in the vicinity of the tubular bone fracture, and for providing a space between said setting device and the surface of the tubular bone in the vicinity of the tubular bone fracture; and
C) means in and cooperating with the means for positioning and in the bores of the end sections of the setting element for axially securing the bone screws in the setting element and stabilizing the bone screws until immediately before the screws enter the bone.

Abstract
The setting device for tubular bone fractures (3,4) consists of a longitudinally extended flattened setting element (20) and of bone screws (10), which in each case are connected to one other by means of a screw (11) and a cone (16) in addition to a taper segment section (15). The setting element (20) has an essentially rectangular cross-section of tissue-compatible high-density material, in particular of implant steel. In each of the two end sections (21) of the setting element (20), at least two bores are provided, which extend through the opposite wide sides thereof. The bone screws (10) are guided through these bores. The setting element (20) consists integrally of the two relatively rigid end pieces (21) and a connection piece (31) lying therebetween. This connection piece (31) is in comparison with the end sections (21) elastic as its cross-section is smaller than that of the end sections (21). The compact setting device formed in this way can be implanted under the skin and enables transverse forces as well as moments of flexion and torsion in the area of the fracture to be eliminated, without the implantation causing additional circulatory disurbances. Further, the normal force in the fracture area can be adjusted.
