摘要：
A system for the amelioration of a recess (56) is disclosed, particularly of a recess in a porous, perforate material having cavities freed by the recess, said system comprising an element (2) for generating or coupling in mechanical energy, and a cylindrical collar (4, 40) having a central recess (44,45) for receiving a guide pin (8), wherein the guide pin (8), having a cannulation (35), is provided to be inserted substantially as far as the bottom of the recess (56) under positioning using a wire (52) before mechanical energy is applied, wherein the guide pin (8), in the area of the end thereof directed toward the bottom of the recess (56), is surrounded by an amelioration sleeve (7), wherein the external cylindrical jacket surface of the amelioration sleeve (7) has substantially the same external diameter as the collar (4, 40), and wherein the guide pin (8) is received movably in the central recess (44,45) such that, when mechanical energy is applied, the collar (4,40) can be moved relative to the guide pin (8) in the direction toward the bottom of the recess (8) while liquefying and laterally and/or longitudinally displacing the material of the amelioration sleeve (7).
