Hip fracture is one of the most severe complications of falls in older people and is considered a major public health issue. Current clinical assessment tools for hip fracture include measurements of bone mineral density (BMD) via dual energy x-ray absorptiometry (DEXA). Decreased BMD is associated with decreased bone strength and thus increased fracture risk. However, BMD is insufficient for predicting fracture risk and many individuals who suffer fracture are considered to have normal, healthy values of BMD. Subject-specific finite element (FE) models constructed from patient computed-tomography (CT) scans offer an alternative approach for assessing bone strength and fracture risk. Finite element analysis (FEA) is an increasingly mature technique that shows improved performance in the prediction of fracture risk compared to assessments of BMD. Nonetheless there are still inconsistencies between experimental results and those obtained through FEA. This thesis explores the effect of concurrent, sideways fall-related impact and hip muscle forces on femoral neck stresses in orthotropic FE models of the ageing femur. This is achieved by integrating data from the following three independent, computational methods: ... (continues
