DEVICE FOR TREATMENT OF SHOULDER FRACTURES IN SMALL HOME ANIMALS

A useful model - the apparatus for treating fractures of the shoulder blades of small pets - belongs to the field of veterinary surgery, and can be used to restore the integrity and anatomical relationship of the shoulder blade in case of damage.

The use of external fixation devices in clinical medicine is known (1, 2). However, they cannot be applied in veterinary practice, since their design features do not take into account the structure of the skeleton and the topographic and anatomical relative positions of organs and tissues of animals.

Known compression and distraction apparatus for the treatment of hip fractures in small pets (3) containing articulated external supports with mounted bone retainers in the form of spokes and rods. However, this device also cannot be used in the treatment of damage to the scapula.

The objective of the claimed utility model is to develop an apparatus that provides the possibility of reposition and stable fixation of the scapula during traumatic injuries.

This problem is solved by the fact that in the apparatus for treating fractures of the scapula of small domestic animals, containing connected to each other with the possibility of movement of the extreme and intermediate supports with clamps and rods mounted on them, as well as connecting and fixing elements, the intermediate support is made in the form strips with ends bent in opposite directions, provided with two rows of holes arranged in a checkerboard pattern, and connected to one of the extreme supports in series interconnected between wallpaper with the ability to move in mutually perpendicular planes with distractors, and on the other, with arched curved rods equipped with threaded threads at the ends, while the ends of the spokes are fixed in the rods of the threaded rods installed with the possibility of reciprocating displacement in the holes of the intermediate support. It is also envisaged that spherical washers can be installed on the threaded ends of the arcuate curved rods.

In the diagram - FIG. 1 - shows a device for the treatment of fractures of the shoulder blades of small pets.

The apparatus for treating fractures of the scapula of small domestic animals contains extreme supports in the form of an arc 1 and a rectangular bar 2, as well as an intermediate support 3, made in the form of a bar with ends bent in opposite directions. The supports 1, 2 and 3 are provided with through holes 4, and in the intermediate support 3 they are made in two rows and are staggered.

The intermediate support 3 is connected to the arc 1 sequentially interconnected with each other with the possibility of movement in mutually perpendicular planes by the distractors 5, 6 and 7, and with a rectangular bar 2 - by means of arcuately curved rods 8 equipped at the ends with a threaded thread 9.

On the supports 1 and 2 with the help of brackets 10, threaded clips 11 are fixed. In turn, the ends of the spokes 12 with thrust pads 13 are fixed in the rods 14 of the threaded screws 15 installed with the possibility of reciprocating displacement in the holes 4 of the intermediate support 3.

It is also envisaged that on the threaded ends 9 of the rods 8, spherical washers 16 can be additionally mounted.

The individual parts and components of the apparatus are interconnected using fastening nuts 17.

The device is used as follows.

After anesthesia and processing of the surgical field, at least two spokes 12 with thrust pads 13 are parallel to each other through the proximal fragment of the scapula from the opposite directions 13. The ends of the spokes 12 are fixed in the rods 14 of the threaded rods 15 mounted on the intermediate support 3 with the possibility of reciprocating displacement.

In the distal fragment of the scapula and the vertebral segments located in the projection of the scapula, threaded retainers 11 are inserted, the ends of which: with the help of brackets 10 are mounted respectively on the supports 1 and 2.

After that, the intermediate support 3 using threaded distractors 5, 6 and 7, interconnected with the possibility of movement in mutually perpendicular planes, are connected to the support 1, and by means of arcuate bends 8 - to the support 2. Moreover, the installation on the threaded ends 9 8 spherical washers 16 allows you to level the deviation of the position of the support 2 relative to the position of the intermediate support 3. By tightening the fixing nuts 17, the position of the individual nodes and parts of the apparatus is stabilized.

in the postoperative period, if the reposition of fragments was not performed during the installation of the apparatus, it is carried out in a dosed manner. To displace the proximal fragment in the lateral direction, the locking spokes 12 are simultaneously tensioned by shifting; threaded bars 15 are moved in diverging directions of the rods 14. The angular displacement of the proximal fragment is eliminated by the thrust of the spokes 12 in opposite directions. The reciprocating displacement of the pins 15 causes the proximal fragment to be moved respectively in the dorsal or ventral directions. Having set the proximal fragment to the anatomically correct position, the distal fragment is repositioned. For this, the displacement in the dorsal or ventral direction is eliminated by compression or distraction along the threaded rods 5 and 7. The distal fragment is displaced in the cranial or caudal directions by distraction or compression along the threaded rods 6. The lateral or medial displacement of the fixation rods 11 of the distal fragment is performed laterally or medially its movement in the indicated directions.

Having completed the reposition of fragments, the apparatus systems are stabilized by fixing with fixing nuts 17. After the fracture consolidation is achieved, the apparatus is dismantled in the reverse order.

Using the apparatus allows for reposition and stable fixation of the scapula during traumatic injuries.
