1. A system for the amelioration of a recess, said system comprising:
an element for generating or coupling in mechanical energy,
a guide pin, and
a cylindrical collar with a cylindrical jacket surface having an external diameter and having a central recess for receiving said guide pin,
wherein said guide pin, having an axial central through bore in the form of a cannulation, is provided to be inserted substantially as far as a bottom of the recess under positioning using a wire inserted into said cannulation of the guide pin, before mechanical energy is applied,
wherein said guide pin, in the area of the end thereof directed toward the bottom of the recess, is surrounded by an amelioration sleeve made from a material that can be liquefied by mechanical energy,
wherein the external cylindrical jacket surface of the amelioration sleeve has substantially the same external diameter as the collar,
wherein said guide pin is received movably in the central recess such that, when mechanical energy is applied, the collar can be moved relative to the guide pin in the direction toward the bottom of the recess while liquefying and laterally and/or longitudinally displacing the material of the amelioration sleeve,
wherein said cylindrical collar has a circular cylindrical jacket surface, and the amelioration sleeve has a circular cylindrical jacket surface, and wherein the external diameter of the collar and of the amelioration sleeve are substantially the same as the internal diameter of the recess to be ameliorated,
wherein said cylindrical collar, at its distal end, has a circumferential distal edge tapering toward said distal end,
wherein the amelioration sleeve is a simple hollow cylinder,
wherein said central recess of said cylindrical collar is a circular cylindrical recess which is arranged coaxially with respect to its cylindrical jacket surface,
wherein the amelioration sleeve has a circular cylindrical recess for receiving the guide pin,
wherein the guide pin has a circular cylindrical outer surface, and
wherein the internal diameters of said recesses are substantially the same as the external diameter of the guide pin, or in case of the circular cylindrical recess of the amelioration sleeve, this circular cylindrical recess is larger than the external diameter of the guide pin to adapt for the amount of material to be liquefied.
