Popis: The concept of the so-called isoelastic implant is re-evaluated in three different aspects, using old and basic principles of mechanical engineering. All three are different approaches to the nut and bolt model. The results of these calculations confirm the well-established engineering knowledge that all such essentially cylindrical interfaces necessarily result in a stress concentration in the area beginning (or ending) the load-transmitting interface closest to the point of load application if loaded axially, and that this concentration is more pronounced the more the situation of isoelasticity is approached. Some general conclusions as to the limits of the usefulness of the concept of isoelastic implants and some possible advantages of their applications are outlined in the discussion.
