SU1247004A1 - Arrangement for reposition of fractures of forearm bones - Google Patents

Description

The invention relates to medical technology and may be used in traumatology and orthopedics.

The aim of the invention is the possibility of eliminating the transverse and osteal displacements of bone fractures with the restoration of the anatomical gap between the radial and ulnar elbows.

FIG. / Shows a device for exposing bone fractures to forearm, axonometric projection; Fig. 2 shows the holder, fragment; on fig.Z - reparative node with a convex plate, a fragment; figure 4 is the same, with a flat plate, a fragment; FIG. 5 shows the device superimposed on the horse; Figure 6 shows the internal and internal rings with the holder; section, disassembly.

The device contained a piece of I shoulder with straps 2, connected by means of threaded rods 3, ga-. ek 4, strips. 5 with a support ring 6, which by means of distractors 7 is movably fixed by nuts 8 with a forward ring 9 with an inner ring 10, made mainly of X-ray transparent material and interconnected by means of adjusting screws P. On distracters 7 it is movable and The eccentric fixed repair unit is made-i,: Nush in the form of a dvuhs flat 12 or convex 13 Sh1astin, made mainly of X-ray transparent material, connected with. Distributor d and 7 using hinges 14, counter threaded rods 15 and nuts 16. The cis- todertal is made in the form of two oval plates 17, fixed in a manner of POM11Sch hinge.in 18, threaded rods 19 and nuts 20 in heads 21 The threaded rods 22, in turn, are fixed to the inner ring with 10 nuts 23. The hinges 18 provide the possibility of creating a conical position of the plates 17, and the adjusting screws 11 provide directional rotation and fixation of the inner ring 10 and with it the hardener 17 relative to about outer ring 9,

The device is used as follows.

For fractures of the radius in a typical place, the damaged

the limb in the device so that the patient's hand is located between the plates I7 of the holder, the shoulder is fixed by straps 2 to the shoulder of the shoulder 1, while the optimal level of the bed 1 is achieved by fixing one of the threaded rods 3 in the hole of the support ring 6 and fixing the slats 5. Relaxed are

the hinges 18 and the rotation of the nuts 20 relative to the threaded rod 19 attach the plates 17 to a cone tightly covering the brush at the level of the tape and the TONG}, fix the reached position of the plates 17 with the nuts 20 and 23 and the hinge 18. Rotate the nuts 8 to achieve the desired degree of distraction distal fragment of the radius. The adjusting screws 11 are relaxed and, by rotating the inner ring 10 relative to the outer ring 9, the forearm and brush position are pronounced, fixing this position by rotating the adjusting screws 11. Install the Shuysky plates 12 of the repository unit on the back and palm surfaces of the forearm at the level of each of the radius bone with fixation of the predetermined position of the plates 12 by the hinges 14. Using the nuts 16, the plates 12 are removed, eliminating the displacement of the fragments. Radiological control is performed and recorded from known

ways, then dismantle the device in reverse order.

For fracture :; both bones of the forearm apply a repopic knot with convex plates 13, fixing them with the back and palmar surfaces of the forearm at the level of the fracture: ma, at E. TOM pressure of the plates, soft tissues, respectively, with the interosseous membrane, push apart the elbow and radial fragments bones in the optimal range, that when using known devices. .. are usually carried out by hand. After radiological control of correctness of the juxtaposition of fragments and their fixation, the device is dismantled in reverse order.

Example. Ill L., 58 years old, delivered to the MSP on 03.03.85. With a diagnosis of a closed extensor fracture of the left radial bone in a typical month

those with offset debris. On the same day, under local anesthesia with 2% novocaine, the displacement of fragments of the radial bone with the proposed device for reposition of fractures was eliminated.

bones forearm. Imposed plaster Longuet. On the control radiograph achieved complete mapping of fragments. Sick sent. for outpatient treatment.
