    摘要： Augments systems and methods for attaching two or more augments to an underside (50) of a tibial baseplate (16) are disclosed. An augment system (100) can include a first augment (102) having a superior surface (106) and an inferior surface (108), the superior surface configured for attachment to the underside of the tibial baseplate. The augment system can include a second augment (104) having a superior surface (110) and an inferior surface (112), the superior surface configured for attachment to the inferior surface of the first augment. The first and second augments can be formed of different materials. One or more additional augments can be used with the first and second augments, and the augment system can be stacked on a resected surface of the tibia. In an example, the augment that directly contacts the resected surface of the tibia can be formed of a porous material, such as to facilitate bone growth.

    摘要： An augmentation system for an implantable bone prosthesis, such as a femoral component of a knee joint prosthesis, includes an augmenting block (12) having an aperture (14) disposed therein. A collet (16) having an expandable distal end (16), extending beyond one surface of the augmenting block, is positioned within the aperture. The proximal end of the collet includes a cavity (17) that receives an expansion pin (20) that is adapted to communicate with the collet to expand the collet. The distal end of the collet is adapted to fit within a mounting cavity (35) 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. Advancement of the expansion pin 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. The expansion pin can include threads which mate with corresponding threads within the cavity of the collet. Alternatively, the pin and collet cavity can include ratchet and pawl-like surface features.
