[The stresses in femur (author's transl)].

The influence of pull in the iliotibial tract on the stresses in the human femur was investigated using the finite element method. Stresses and strains were computed for a model, assuming different forces in the iliotibial tract. The results were experimentally confirmed using strain gauges. The pull in the iliotibial tract mainly reduces the high tensile strains at the lateral side.
