Abstract

This invention relates to traumatology. The purpose of the invention is to reduce the duration of treatment. The annarat contains threaded rods 1 and 2 and clamp holders 3 and 4 mounted on them by means of nuts 5. The threaded rods are connected by a reposition assembly. Screws 9 are installed in bracket 6. Screws 7 are rotated using these screws. Shelves of brackets 6 and 7 are connected with bolts 10 and II, on which they are installed, with the possibility of moving the sliders 12 and 13, which are fixedly connected to threaded rods 1 and 2. The device does not produce an exact dosed reposition of bone fragments. 4 il. CD co CD

Description

The invention relates to medicine, namely to traumatology.

The purpose of the invention is to reduce the time of treatment by providing angular displacements of the bone framing planes.

FIG. 1 shows an apparatus for reposition and fixation of bone fragments, front view; in fig. 2 - the same, top view; in fig. 3 - apparatus reposition assembly, front view; in fig. 4 - reposition node, top view.

The apparatus for reposition and fixation of bone fragments contains threaded rods 1, 2 and installed on them by means of

ten

Elimination of the displacement of fragments along the length is performed by rotating the nuts, which move the spokes 3, 4 along the length of the threaded rods 1 and 2.

Elimination of the width offset in the desired direction is carried out by rotating the bolts 10 and 11.

The removal of the rotational displacement is done by rotating the screws 9, which rotate the bracket 7 relative to 6, together with the bracket 7, the distal fragment is rotated.

The elimination of the angular displacements of fragments is carried out by rotating the screws 14 and 15, which at the same time turn the slide blocks 12.

the nuts, respectively, the knit holders 3, 4 s and 13, together with them the distal fragment with the spokes 5, and the threaded rods are relatively proximal

linked by a reposition knot. The reposition assembly is made in the form of two U-shaped brackets 6 and 7, the shelves of which are mutually perpendicular, and the bases are connected by an axis 8.

Screws 9 are installed in the bracket 6, which, in the course of reliable stabilization for the entire period, is screwed in or unscrewed, and the section of the bone fragments leads to rapid

dosed rotation of the bracket 7 around the axis 8 is carried out. The shelves of the brackets 6 and 7 are connected by bolts 10 and 11, on which sliders 12 and 13 are mounted with the possibility of translational movement;

The device allows accurate dosed reposition of bone fragments with the restoration of anatomical integrity, which, given the compression and

and correct bone adhesion, reduction of hospital stay and more, early rehabilitation.

Visionally connected with threaded rods 1 and 2. The slide blocks are equipped with screws 14 and 15, respectively, alternately screwed or unscrewed.
