Sažetak
In modern hip arthroplasty a mechanical reconstruction is demanded which works as close as possible to the anatomical demands. From the mechanical point of view there are three principal points to be obeyed, which are: 1. problems to due necessary replacement, 2. the necessary mobility (degree of freedom and the needed domains for the different movements), 3. failure analysis with view to there possible influence to lifetime, 4. the forces acting on it (gait analysis). The first necessity of hip replacement is of course given by medical findings. However the lifetime of the artificial replacement by the mechanical properties of the material used and by the design of the couple cone to sleeve which means by the load transfer and of course by kind of loading (ad. 4).
