Hip fracture following a fall is common in elderly people who have poor bone strength. The pattern of trochanteric hip fractures differs among patients and some cases of fracture are difficult to reduce. The loading condition at the proximal femur is one of the factors that affect the fracture pattern. Understanding the relationship between the loading condition and the fracture pattern would improve the accuracy of reduction and promote early healing. A previous study suggested that a bone fracture analysis based on finite element (FE) analysis could be useful for clarifying this relationship. However, such bone fracture analysis has not been verified. This study verifies the validity of a bone fracture analysis by a comparison with the results obtained in a mechanical test for porcine femurs. For both the mechanical test and the FE analysis, a fall to the side was assumed. The tendencies of the load-displacement curves obtained in the mechanical test and the analysis were consistent. There was significant correlation between the mechanical test and the analysis results for all evaluation indices. Furthermore, the fracture states were mostly consistent. These results confirm the validity of a bone fracture analysis.
