Purpose: The paper presents results of experimental analysis of femur and femur - expandable intramedullary nail system. The aim of the work was to determine displacement in three models. In addition, the torsion of the system aiming at determining the moments depending on the torsional angle of the bone was carried out. Design/methodology/approach: Three femurs were selected for studies. The analysis was carried out on the femur - expandable intramedullary nail system. The influence of the loads and displacements on the bone - nail system on the results of experimental analysis was analysed. In order to carry out calculations, three models were selected: model I - bone without fracture gap, model II and III - femur with expansion intramedullary nails - fracture gap was located 100 mm under greater trochanter. The studies were performed on femur models produced by Swedish company Sawbones. The intramedullary "Fixion IM" nails (Ti-6Al-4V alloy) were implanted into the bone. Displacements of determinated models were being recorded from the sensors every 100 N from 10 N to 2000 N. Findings: The analyses showed the difference in displacements, depending on the selected models. Research limitations/implications: The limitations were connected with simplification of boundary conditions during analysis which were the result of the simplification of the models. While studying, muscles and ligaments supporting the bone in anatomic position were not taken into consideration. Instead, the system has been loaded with the axial force (compression). Practical implications: The obtained results can be useful in clinical practice. They can be applied in selection of stabilization methods or rehabilitation as well as in describing the biomechanical conditions connected with type of bone fracture obtained from medical imaging. Originality/value: . The work compares the values of displacement of characteristic points of femur (healthy - model I) with the femur - expandable intramedullary nail system (models II and III) with the applied force. In order to estimate the value of the torsional angle of the upper part in relation to the lower one depending on the applied force, the torsion of the model was conducted. On this basis, it was indicated a maximum moment in which the nail would not become loose in medullar canal.
