The implant is provided with recesses in which therapeutically effective substances are embedded. Each recess is closed by a porous cover which is of a porosity to permit permeation of the therapeutic substance out of the recess while preventing ingrowth of bone tissue. Each cover may be slightly deformed into a convex shape to project from a recess to achieve elastic bonding with a bone.
