Abstract

The invention is intended for the treatment of intraarticular and periarticular fractures in traumatology and orthopedics and provides a multiplane reposition of bone fragments. The device contains supports I and 2, fixing screws 3 fixed at an angle of 120 °, hinge 4, curved rod 6, nuts 7 and 10, distractor 8 with bracket 9 with repositionable rods 1 1 and clamps 12. On the limb they fix supports 1 and 2 or a soft cuff, place the clip 9 against the bone fragment, insert the rods 11 into the fragment and fix them. By releasing the nuts 7 and 10, the fragment is repositioned and compressed. Clamp these nuts and screw the rods 11 through the fragments into the main bone until it stops. The installation of the bracket 9 using a spherical hinge 4 provides multiplane reposition of the bone fragment. 4 il. (Oh (L

FIG.

The invention relates to medicine, namely to traumatology and orthopedics, and is intended for the treatment of intra-articular and periarticular fractures.

The aim of the invention is to provide a multiplane reposition of bone fragments.

FIG. 1 shows the proposed device, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 shows an embodiment of the device on a soft cuff; in fig. 4 - reposition rod.

A device for osteosynthesis of intra- and periarticular fractures consists of a support 1, to which support 2 is attached. On supports 1 and 2 in the radial direction the fixing screws 3 are installed at an angle of 120 ° relative to each other. A support 6 is vertically bent on support 1 using a spherical joint 4 and a clamp 5, the threaded end of which is clamped in the joint by 4 nuts 7. A threaded distractor 8 with a clamp 9 is mounted in the opening of the rod 6 and can be fixed and fixed with nuts 10. At the ends The reposition rods 1 are secured in the holes with locks 12.

If the device is executed on the m-cuff cuff 13, the rod 6 is vertically bent and secured to the bracket 14 by means of a spherical hinge 4 with a clamp 5 fixed on the cuff.

Threaded rod 11 has a thrust chamfer 15, a smooth neck 16, a threaded cone 17, a cylindrical body 18 and a shank 19 under the allen key.

The device is used as follows.

Depending on the nature and location of the fracture, the method of fastening the device is selected and fixed to the limbs or supports 1 and 2 using fixing screws 3 or a cuff 13 with a bracket 14. Using a spherical joint 4, a vertical rod 6 and a threaded distractor 8, fix the bracket 9 against bone fragment. The clamping rods 11 are inserted into the holes of the bracket and screwed into the bone fragments through soft tissues, after which they are fixed with locks 12.

By releasing the nuts 7 and 10, the bone fragment is repositioned and compressed. After that, all the nuts 7 and 10 and the latch 5 are clamped. The clamps 12 are released and the reposition rods 11 are screwed into the main bone through the fragments, so that the chamfers 15 of the rods 11 rest on the fragments and tightly press it to the main bone. Then the whole device is removed from the limb.
