ABSTRACT:
An osteal prosthetic component of a prosthetic joint and a method of implanting an osteal prosthetic component in the medullary canal of a bone are disclosed. The osteal prosthetic component includes a stem for disposition within a medullary canal of a bone and a fluted wedge portion extending from the stem. The fluted wedge has wedge portions which define at least one flute between the wedge portions. An interference fit is formed between the wedge portions and the bone during implantation of the stem into the medullary canal. Movement of the osteal prosthetic component relative to the bone is thereby sufficiently limited to allow tissue growth into a tissue-ingrowth portion at the surface of the stem to substantially prevent micromotion of the stem relative to the bone.
