Osteosynthesis of femoral neck fractures (FNF) is accompanied by a large percentage of various complications. The aim of this research was to study biomechanical implications arising from the stress and strain distributions by use of new device –perforated H-beam implant. A reference 3D femur model has been developed using digital femur geometry. Stress and deformity characteristics after the application of strength were determined by ANSYS, which entails the finite element analysis (FEA) method. This method was used for both for perforated and non-perforated implant models and compared following the application of constant strength. The UTS (ultimate tensile stress) for cancellous bone has been defined as 20 MPA and that for cortical bone 150MPA. Three types of FNF were realized according to Pauwell classification system. The mechanical behaviour of both models has been investigated. A vertical strength of 4000N has been applied in all the analysis.
