Abstract: Femur bone is one of the strongest and important bones which support the major weight of human body. Unexpected sudden impact on the femur bone during accidents may cause severe fractures. When this bone injury is not self repairable, bone scaffold is the only remedy. This research paper analyses the biomechanical effects of the femur bone implanted with porous scaffold made of polyamide/hydroxyapatite material. Porous scaffolds are temporary load bearing members, consisting of 3D porous geometry to support internal cell growth. This study focuses on the study of suitability of the porous scaffold fixed on a damaged femur bone under different loading conditions. This research uses the CT scan data of femur bone of a 75 kg healthy person and presents detailed information on the biomechanical analysis of the femur bone during common physical activities using finite element analysis.
