title: Biomechanics of the femoral neck. Calculation of pressure and tension distribution in the human femoral neck, applying principles of the theory of elasticity and strength of materials.
abstract: Theoretical aspects on the influence of the shape of the human femoral neck in terms of tension intensifying slots are presented. Static stress is calculated. It is shown that tension in the cranial periphery of the neck is twice as high as expected. The pressure at Adam's arc is 1.5 times higher. Further it is shown that tension does not increase from neutral centre to periphery in a linear but in a parabolic function.
