Abstract
A custom made femoral component is made using the femoral cavity and an internal latex envelope as the mold. After the femoral cavity is worked into a roughly conical shape, an internal latex envelope is inserted into the cavity and filled with bone cement. An endoskeleton is inserted down the femoral cavity into the bone cement. The internal latex mold conforms to the shape of the cavity and an accurate negative of the cavity is created as the bone cement solidifies. The femoral component is pulled from the cavity and the internal latex envelope is peeled off the component. All traces of the internal latex envelope is removed from the femoral cavity and component. The femoral component is then reimplanted.
