[Tests of durability characteristics of osteosynthesis of femoral neck fractures by different fixators under static and dynamic loading].

Test bench experiments on the models of femoral neck bone fractures with the use of various kinds of latches has been carried out for evaluation of durability characteristics of the osteosynthesis, using universal test machine "Zwick-1464". 40 preparations of proximal-diaphysis parts of the femoral bone from 28 females and 12 males (mean age 71 years) were used one day after death. The models of basal, transcervical and subcapital fracture were formed with the angle between its planes and horizontal plane (the angle of Pauel's) 30, 40 and 70 degrees.
