RU7299U1 - DEVICE FOR TREATING SLIP FALSE JOINTS OF LONG TUBULAR BONES - Google Patents

Abstract

A device for treating oblique false joints of long tubular bones, comprising three annular supports with brackets and interconnected by distraction rods, characterized in that in the distal and proximal supports are installed screw rods perpendicular to each other, and in the middle support, located in the area of the false joint, screw rods are installed towards and parallel to each other.

Description

Device for treating oblique false joints of long tubular bones.

The proposed device relates to medicine, in particular to traumatology and is intended for the treatment of oblique false joints of long tubular bones.

The known method / 1 / treatment of oblique false joints of long tubular bones, which is carried out using the apparatus of Iyaizarov, consisting of three annular supports with brackets for attaching sshshchivy clamps, distraction rods, rigidly fastening the support, as well as staple fixators that are rigidly fixed in annular supports using brackets. However, to implement this method, it is necessary to perform an open osteotomy of the end of one of the fragments and the introduction of the acute end of the other fragment into the bone marrow canal esecinated fragment.

However, this device has several disadvantages: the installation of at least 8-10 spoke retainers creates the risk of damage to important anatomical structures, the risk of infected complications around the spoke retainers increases as a result of injury to the skin spokes and the creation of a large number of entry gates for infection.

We first proposed a device for treating oblique false joints / figure 1 /, consisting of 3 annular supports 1, distraction rods 2, which rigidly fasten the annular supports Guvzhdu themselves, screw rods 3, rigidly mounted in the annular supports using brackets .We used threaded screw rods and self-tapping tips.

The device operates as follows: screw rods are inserted into the proximal metaphysis of the tibia by self-cutting perpendicular to each other in the direction from front to back, from outside to inside and from front to back, inside and out. The rods are located at a certain distance between each other, allowing the ring support and brackets to be installed between them, in to

The installation directions and directions are similar to the previous ones. Ring supports connect distraction rods to each other. At the level of the false joint, another ring support is installed. Two channels are drilled through the zone of the false joint through both fragments of the tubular bone and two screw rods are screwed into them. fastened through the bracket to the ring support,

The proposed device for the treatment of oblique false joints makes it possible to treat false joints in a closed way. A closed method for treating oblique false joints significantly reduces the surgical trauma of surgical intervention. The use of rod fixators reduces the complexity of osteosynthesis compared to the Ilizarov spoke apparatus. The number of fixators is halved, not at the expense of fixation rigidity, while the likelihood of inflammatory complications around the fixators is reduced.
