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 aim of this study was to examine the relationship between the structure of the proximal femur and its individual anatomical variability, namely the size of the femoral neck and the angle of torsion. These results suggest that the mor-phogeometry of the femur (the femoral neck axis length and width of the neck) may influence on the risk of fractures of the femoral neck in people of different body type

45 morphometric parameters of femoral bones (n=45) have been studied. Their 3 shape variants have been picked out according to thickness-prolixity index. The peculiarities of entry angle of diaphysial artery in connection with the bone shape have been revealed. Zones of the most and the least concentration of nutrient foramen have been determined
