Abstract
In this research, three-dimensional modeling of the residual limb of a transfemoral amputee is performed, which includes skin, fat tissue, muscle and residual femur. The loading conditions are established for the support phase during the normal gait cycle, the standing and walking through stairs of a transfemoral amputee of 88 kg and a height of 1.7 m. An analysis of the incidence of load conditions on the stresses and deformations in muscle tissue was made to establish its influence on the development of deep tissue injuries (DTI) in the residual limb of the amputee. From the analysis it was obtained that the average compressive stress is close to 18.6 kPa and the highest average strain at compression is 56.8%, it happens when the individual is walking through stairs or slope. The maximum concentration of stress and strain occurs in the distal area of the residual femur in muscle tissue.
