Highlighting the stresses and strain state of trabecular structure in case of proximal epiphysis fracture of the femur (with reference to femoral neck fracture) where, for osteosynthesis, are used cannulated screws, raises multiple technical difficulties. For this reason the present study proposes a synthetic 2D model through which we can identify areas of maximum stress and understanding how the trabecular structure is loaded. The analysis is based on different investigation methods: experimental method using digital image correlation and numerical method using finite element analysis. Mechanical load is specific to unipodal support. For 31-B1.3 fracture type, using Pauwels classification, it was determined that the most dangerous situation is registered when the fracture line is at a 70o angle to the horizontal line.
