In the work comparison of two methods of pertrochanteric fracture fixation has been carried out: external one, with the help of the transosseous device and immersed one, by the dynamic femoral system. The investigation of the process of dislocation of fragments has been done on biophantomes. The dynamic compression in the external fixation device increases stability of the biomechanical system «bone-fixator» in 3-4 times. The use of single-stage fracture compression with dynamic femoral system allows to create stable fixation of fragments, adequate for early mobilization of patients

The article concerns the current status of the topical problem in traumatology - treatment of juxta-articular fractures of proximal part of a femur and their effect. Analytical review of domestic and foreign literature has allowed to determine the basic problems in treatment of the particular group of patients and to define long-term trends of osteosynthesis of juxta-articular fractures of proximal part of a femur at the present stage

In the present research a comparison of two techniques of transosseous fixation of pertrochanteric fracture has been drawn. By way of example linear relocations of fragments have been measured in 8 biodummies (femurs of cows) in two groups through three series of loadings along the long axis of a femur with a step of 490 N from 980 up to 2940 N. The specific load in the range of 16,08±0,65 N/sm2 — 16,32±0,065 N/sm2 causes linear fragment dislocation within 0,13±0,016 mm — 0,08±0,03 mm. Compressive variant of osteosynthesis improves stability of biomechanical system "a bone-fixator" 3-4 times as much
