ABSTRACT:
An augmentation system for an implantable bone prosthesis, such as a femoral component of a knee joint prosthesis, includes an augmenting block having an aperture disposed therein. A collet having an expandable distal end, extending beyond one surface of the augmenting block, is positioned within the aperture. The proximal end of the collet includes a threaded cavity that receives a set screw which is adapted to communicate with the collet to expand and contract the collet. The distal end of the collet is adapted to fit within a mounting cavity of a joint prosthesis. With the augmenting block placed on the appropriate surface of the joint prosthesis, the distal end of the collet is positioned within the mounting cavity. Tightening of the set screw causes the distal end of the collet to expand, thus frictionally and/or mechanically engaging the interior walls of the mounting cavity to firmly secure the augmenting system to the prosthesis.
