SU563968A1 - N.a.serebrennikov device for repositioning and fixing pelvis bones in case of fracture - Google Patents

Description

9 ring bracers, and 10 heads with turnkey mountaineers.

Bit stops 7 zakuppetvu rack in coaxial Wtu. k.Ah 11, and screw bolts 4 provide with turnkey heads 12, with

This cTOEitH 3 can be rigidly fixed on the frame 1 with retaining screws 13,. The device is used to treat patients with rupture of the sacroiliac. thorax and pubic joints, fracture of the superior bone in the posterior section, combined with a rupture of the dorsal joint or a fracture of the pubic and ischial bone on the opposite side with a divergence of the pelvis half the width of the pelvis.

In the case of a vertical or diagonal fracture with the mixing of one of the halves in height and width, the vertical joint was previously eliminated with a skeletal stretch followed by application of the device and elimination of the halves of the width of the tapping 4.

The device is applied under general anesthesia or intrapelvic novokatgovoy blockade and with prior introduction of novocaine into the area of insertion of the screw stops 7 and the hinged stops 6,

After pretreatment of the skin in the projection of the upper-posterior edge of the acetabulum, an indent of 1-1.5 cm posterior to the tip of the greater trochanter is inserted through small tissue incisions (puncture type 0,6-O, 8 cm) screw stops 7 to contact with the bone. The locking screws 13 of the rack 3 are firmly fixed and, using a key, screw the stops 7 by immersing the sharp ends of them into the bone substance of the iliac bones.

Next: through small incisions of soft tissues (0.6-0.8 cm), in the projection of the anteroposterior iliac bones, stops 6 are screwed into the pelvic wings with pointed pointed ends to a depth of 2 to 2.5 cm after loosening the hinge clamps 5. Enter the stops 6 in the pelvic wing rigidly fix the hinges 5 and by turning the screw fasteners 4 in the counterclockwise direction, they pull the pelvis wings together, eliminating the right or left halves of the pelvis in width. If necessary, the approximation of the halves of the pelvis can be carried out using a screw

4, located on the side of the injury (mixed half of the pelvis), since the independent movement of the uprights 2 on the frame 1 makes it possible to act in isolation on the right and left half of the pelvis. The convergence of the posterior divisions (posterior half ring) is accomplished by rotating the heads of the screw stops 7 in a clockwise direction. The result was checked with a control radiograph. The term fixation device 1.5-2 months.

Strong fixation of the pelvic fragments in case of its complex fractures allows to avoid additional immobilization of the extremities by the system of permanent stretching, eliminates the danger of secondary displacement. It makes the patient active in bed, creates favorable conditions for his care and allows him to start earlier functional and physiotherapeutic treatment aimed at restoring the function of the lower Limbs,

The use of the device in the treatment of patients with pelvic fractures allows them to be transported under evacuation conditions in the first days after application of the device by using additional immobilization, which is important in conditions of military field surgery.

When using the sample of the device described, good anatomical and functional results were obtained.
