Abstract
An implantable prosthesis having at least two portions which are displaceable relative to each other, in particular a prosthesis for the upper end of a human upper arm comprising a shaft which can be inserted into a bone passage and a dome-shaped joint head which is to be associated with the adjacent joint head and which can be connected to an end face of the shaft in an eccentric position or a neutral position relative to the center axis thereof by means of an intermediate disk which has a circular periphery and which comprises both in relation to the joint head and in relation to the shaft a respective insert pin or the like peg-shaped portion formed thereon which can be inserted into a bore, wherein the mutually displaceable portions of the prosthesis are arranged steplessly displaceably relative to each other at at least one displacement plane which is determined by the surface of a portion about axes which are determined by the insert pins of the intermediate disk.
