SU1459661A1 - Arrangement for osteosynthesis in fractures of tip of the elbow - Google Patents

Abstract

The invention is intended for trauma. The purpose of the invention is to provide spatial reposition of fragments and variable-compression stimulation of bone regeneration in the area of the fracture. The device consists of brackets 1 and 2 with spokes 3 and 4, fastened with threaded rods 5 and 6. In the middle of brackets 1 and 2, there is a threaded bracket 7 fastened with nuts 8 and 9. At the end of console 7, nuts 10 and 11 fasten coupling 12 Which is the base of the spring bracket 13 with a hole 14 at the end of the console 7 and a fork 15 on which the nuts 20 and 18 reinforce the arc 20 with threaded pins 22 and 23. At the end of the console 7 with a bolt - axis above the spring 30 and the washer 31 with eccentric loops 33 strengthened the bar 34, which is movably connected to the end of the rod 36 and the reach 38, over on the shoulder. In the course of the operation and treatment, the ulnar bone fragment is repositioned and its subsequent correction. During the natural bending of the elbow joint, the strap is rotated, which with its eccentric loops exerts a small pressure through the spring 30 on the bracket 13, causing a stimulating, variable-compression effect on the fracture area. The rehabilitation period is reduced by 15-20%. 8 il. ® (L
