Abstract: The invention provides an implant system for treating bone defects or discontinuities and a method for producing such an implant system. The implant system (100) comprises: a first implant element (110) which is insertable or inserted into a bone defect or a discontinuity (2) of a human bone (1), a second implant element (120) which is fixable or fixed to the human bone (1), wherein the first implant element (110) is attachable or attached to the second implant element (120) by means of at least one biodegradable connection means (125) in order to fix the first implant element (110) relative to the human bone (1), wherein the first implant element (110) comprises a shell section (111) and an inner section (112) at least partially enclosed by the shell section (111), wherein the shell section (111) has a first pore-and-strut structure, PSS, and the inner section (112) has a PSS differing from the first PSS.
