A prosthesis which can be implanted into the cavity of a bone or between spaced apart bones defines a passage with ports for evacuation of air and/or other matter from the cavity or cavities which are to receive bone cement or other cement. The prosthesis is inserted and centered prior to introduction of cement, and its passage or passages are connected to a suction generating device during admission of cement. If necessary, the prosthesis can be confined in a jacket to prevent overheating of adjacent tissue during polymerization of the introduced mass of cement. The passage or passages in the prosthesis can be filled with cement and/or with medications which penetrate into the adjacent tissue subsequent to implantation of the prosthesis.

A prosthesis for implantation into at least one bone, comprising an elongated implant body having an external surface, a proximal end and a distal end and being provided with at least one elongated at least substantially sealed suction passage extending between said proximal end and said distal end,

A prosthesis for implantation into at least one bone, comprising an elongated implant body having an external surface, a proximal end and a distal end and being provided with at least one elongated at least substantially sealed suction passage extending between said proximal end and said distal end, said implant body further having at least one first port for admission of a flowable substance into said suction passage at said distal end and said at least one first port communicating with a space at least partially surrounding said external surface and being surrounded by the at least one bone upon introduction of said distal end and of said external surface into the at least one bone, said implant body further having at least one second port for evacuation of a flowable substance from said at least one suction passage and said at least one second port being disposed at said proximal end and being connectable with a suction generating device to draw flowable substance into said at least one suction passage by way of said at least one first port and to thus draw a flowable bone cement into said space as a result of the establishment of a negative pressure in said space.
