Calculation of the mechanical properties for an amputee hip joint

The theoretical based of real forces exerted on the human hip joints are calculated. Newton's law at condition of equilibrium to forces and torques applied on human hip joints is suggested theoretically and then applied to a case of hip joint injure and prosthetic. It was found that the forces act on the hip joint is nearly two and a half times the weight of the certain person. The lost of weight for the amputee have been taken under account in calculation to improve local manufacturing in Sudan

Calculation of the mechanical properties for lower limb below knee amputee using partial differential equation and finite element method

The theoretical based of real displacement forces exerted on the below knee for an amputee prosthetic are considered. Partial differential equation [PDE] in boundary condition surround of prosthetic is theoretically suggested in order to find forces components and stresses. The theoretical model is applied to simulate the prosthetic. The data of image segmentations are found to support the results obtained using bio-mechanics simulation. Furthermore, it is important to mention that the fitted socket to the underneath knee prosthetic should have a large safe margin with surround of soft tissue
