Abstract

FIELD: medicine. in particular to traumatology. In order to achieve a rigid fixation of fragments with a closed reposition, a short line is produced. ) an incision of soft tissue under the lower pole of the patella outwards from its own ligament. The latch pin through the microschal neck of the femur is immersed retrogradely in the distal fragment. The distal1) H, 1Y and proximal fragments are mapped and the pin is hammered into the proximal fragments. The distal end of the pin is immersed at the level of the cortical plate.

Description

This invention relates to medicine, namely to traumatology and orthopedics.

The aim of the invention is to achieve rigid fixation of fragments with closed reposition by inserting a fixator through the distal into the proximal fragments.

Example. Ill I. Local status: right lower limb in the position of external rotation and flexion of the knee joint at an angle of 140 °. Edema, deformity, pathological mobility in the lower third of the right thigh. On roentgenograms of the right femur, there is a helical splinter fracture of the femur in the lower third with displaced fragments. Diagnosis: helical splintered fracture of the lower third of the right femur with displacement of fragments. The operation was performed: closed intra-medullary osteosynthesis of the lower third of the right femur. Anesthesia The position of the patient on the back. Right lower limb bent at the knee joint at an angle of 90 °. A short, linear incision is made in soft tissues under the lower pole of the patella, outward from the intrinsic ligament. The length of the cut is 1 cm. The intrinsic link is displaced inwards. A retainer-pin is inserted through the incision, which is dipped retrogradely into the distal fragments (shorter) through the inter-muscular microhum of the thigh. Next, the distal and proximal fragments are correlated manually under the control of an electron-optical converter and the pin is hammered into the proximal fragments. Moreover, the distal end of the pin is immersed on the level of the cortical plate. The wound is sutured.

On the control P-grams, fragments standing are satisfactory. The postoperative wound healed by primary tension. In the postoperative period, the plaster immobilization of the right lower limb was carried out with the back plaster Longuet to the upper third of the thigh before the wound healed, which made it possible to begin the early activation of the sick, passive gymnastics in the joints of the operated limb. The patient received exercise therapy, massage. The range of motion in the right knee joint is 80 °:

extension of 180 °, flexion of 100 °. There is no effusion in the joint.

Thus, the proposed method provides an increase in the stability of fixation of bone fragments by immersing the pin to the level of a compact substance with an interdiscal membrane, as well as improving the accuracy of reposition in fractures of the femur in the lower third as a result of inserting the pin through the distal

(shorter) fragments, which ultimately leads to good consolidation of the fracture and reduces the duration of disability of patients.
