Stressed state peculiarities of cortical and trabecular bones by two,point asymmetric screw fixation with implant for femoral neck fracture are studied. Layer construction mechanic methods are used for analysis of stresses in cortical and trabecular bones. Biomechanical conditions for non,opening of the junction of the bone parts being joined are determined. It has been found that the total tightness of the broken parts when they rest against each other is secured over the whole fracture section without junction opening under condition that fixing screws are positioned in the trabecular bone without penetration of the thread side surface into cortical bone.
