Abstract

This invention relates to orthopedics and traumatology. The purpose of the invention is to prevent the patellar displacement. The lateral ligaments that support the patella are cut from the patella. The patellar binder is isolated. Chisel knocks tibial bone. Prepare a bone bed. The cut-off tuberosity and the excess bundle area are placed on the formed bed. Then the cut tuberosity is fixed to the tibial bone with the shiel. A latch is applied to the patella binder section so that the awl blade is located in the longitudinal hole of the latch. With gentle blows of the hammer, the reactive teeth of the retainer are inserted into the cortical layer of the tibia. A clamp is set in the longitudinal hole along the blade and a light blow is used to preliminarily insert its sharp needles into the body of the binder and tuberosity. Having removed the awl blade, the screw is screwed into the body of the tibia, with which the final insertion of the needles and clamp into the cortical layer and the clamp body is pressed to the surface more often (L tibia).

This invention relates to medicine, namely to orthopedics of traumatology and surgery.

The aim of the invention is to prevent the patella from being displaced by shortening the patellar binder and optimizing the position of its fixation point on the tibia.

The method is carried out as follows.

The lateral ligaments supporting the patella are cut off from the patella, the tibial tuberosity is cut off, a bone bed is prepared, the proximal end of which corresponds to the place of physiological attachment of the distal end of the patella ligament to the tibial bone. A piece of the ligature to be shortened is laid on the bed, a fixation device is installed on the severed tuberosity, the fixed junction between its reactive teeth is positioned, and it is firmly fixed to the tibia with a needle clamp and a screw passing through the tuberosity.

Example. A patient undergoes a skin incision under general or conductive anesthesia after treatment of the surgical floor. The lateral ligaments supporting the patella are cut off, the patella binder is extracted from its edge, the tibial tuberosity is knocked down with a chisel to form a wedge with a higher inner edge.

A bone bed is prepared, the proximal end of which corresponds to the place of physiological attachment of the distal cone of the patellar patella to the tibia. The cut-off tuberosity and the excess portion of the ligament are brought down by means of reduction and placed on the formed bed. In this position, the cut tuberosity is fixed to the tibia with an awl, the removable handle of which is removed.

Thereafter, passive flexor-extension movements in the knee joint are performed and the features of patella glide are determined. ,

In the normal position of the patella, a clamp is placed on the portion of the patella ligament to be shortened and on the cut-off portion of the tibial tuberosity in such a way that the blade sews when the handle is removed and is in the longitudinal opening of the clamp, the link itself is free under the wide shelf and between it teeth With light hammer blows, the reactive teeth of the retainer are inserted into the cortical layer of the tibia, while their implementation is limited due to the restraining areas of the retainer, whereby the body of the ligament is not subjected to much compression and is not injured, retaining its shape throughout the entire treatment period. A clamp is inserted into the longitudinal hole along the awl blade, and light strokes are used to preliminarily introduce its sharp needles into the bundle body and tuberosity.

Having previously removed the awl blade, the screw is screwed into the body of the tibia, with which the final insertion of the needles of the clamp into the cortical layer takes place and the fixer body is pressed against the surface of the tibia.
