Summary:

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
