Abstract

The invention relates to medicine, namely to traumatology and orthody. In order to provide separate reposition of the radial and ulnar bones with the possibility of ix movement across the width, the carrier base with two fixed guides, counter-running screws between them and the control handle, two movable guides, rigidly connected through a nut with a lead screw, as well as calipers with repaired units placed on them. The supports are mounted on movable sleeves to allow each of the supports to be supported with the repair unit along the axis of the device along the guides using the lead screw. Each repair unit consists of a support column, extended with the possibility of displacement in height and fixation in the desired position, and a bracket fixed at the top of the support column in the fixing collar with the help of a rotating finger and set screws with the possibility of rotational motions in all directions . 3 il.

Description

The invention relates to medicine, namely to traumatology.

The purpose of the invention is a separate reposition of the ulna and radius with the possibility of their movement along the width.

FIG. 1 shows a device for repositioning the bones of the forearm; in fig. 2 - the mechanism of transverse movement of the device; in fig. 3 - device stand.

The device for bone reposition of the forearm contains the pole 1 with an adjustable length, on which the caster holder 3, the primary and secondary distal assemblies 4 and 5 of fixation and the proximal fixation unit 6, and fixation units 6 in the form of brackets 7 with knitting needles, are successively installed on meticulously adjustable posts 2 not shown). The distal fixing units 4 and 5 are mounted on the boom 1 by means of a displacement mechanism 8, made in the form of a frame 9 fixed on the boom 1 with transversely fixed coaxial screws 10 and 11 with carriages 12, which are connected to guides 1 longitudinally arranged on the bar 1. and 14, one of which is threaded, and on which racks 2 of distal units 4 and 5 are fixed by means of sliders 15. The device can be equipped with removable holders 16 of x-ray cassettes.

A device for bone reposition of the forearm is used as follows.

The number and location of the spokes is dictated by the nature of the fracture or the fracture of the a-dislocation, the type of displacement and the necessary direction of the correcting forces, and is chosen in the amount of 2-3 spokes. The stabilizing needle is carried out extra focal through the proximal part of both bones to the forearm, indentation 3-4 cm above the fracture line in the frontal plane. Repone needles having a bayonet or soldered needles, depending on the nature

the displacements are conducted distal to the fracture line, also indented 3-4 cm in the sagittal plane, through each brush separately.

The forearm with the spokes is inserted into the device, the required size is set between the holder 3 and the proximal fixation unit 6, as well as the height of the uprights 2. The stabilizing needle is fixed and tensioned in the bracket 7 of the proximal fixation unit 6. Each of the repairing spokes separately is tensioned and rigidly fixed in the brackets 7 of the distal fixing units 4 and 5.

Rotating the threaded guide 13, the fractions are traced along the length of the forearm, thereby eliminating the displacement along the length.

The transverse displacements of the fragments are eliminated by a dosed change in the lengths of the uprights 2 of the distal nodes 4 and 5. By using separate screws 11 and 10, the displacement of the bone fragments along the width is eliminated.

After comparing bone fragments and eliminating all types of mixing, X-ray inspection is performed in all planes.

After producing the x-ray control and achieving the correct ratio of bone fragments, the limb is fixed

Drives with a plaster cast, do not remove it from the device. After the plaster has hardened, the ends of the spokes are biting over the dressing. The hand is removed from the device. In order to prevent secondary dislocations, the needles are not removed from the plaster dressing, but are additionally covered with several rounds of bandage.
