Abstract

The invention relates to a joint implant part of a joint endoprosthesis. The joint implant part comprises at least one first volume region, at least one second volume region and at least one third volume region. The at least one first volume region defines a bone contact surface region with at least one bone contact surface. The at least one second volume region defines a joint surface region with at least one joint surface. The at least one third volume region comprises neither a bone contact surface nor a joint surface. A modulus of elasticity in the at least one first and/or in the at least one second and/or in the at least one third volume region changes continuously or substantially continuously or discontinuously in at least one spatial direction.
