Abstract
A temporary femoral implant system has a porous mold and a femoral component. The system fits at least partially in a femoral cavity. The mold has a wall with an interior surface and an exterior surface forming an interior space for receiving an antibiotic bone cement. The mold allows the antibiotic to diffuse through the wall to the exterior surface. The femoral component has a stem portion received within the mold. A method of using the implant system includes providing an implant system comprising a mold and a femoral component, inserting the mold into the femoral cavity with the exterior surface facing the femoral cavity, inserting the stem portion of a femoral component into the interior space of the mold and filling the interior space of the mold with an antibiotic bone cement.
