Abstract: An osteotomy guide for indicating the femoral neck resection on a femur and its method of use are presented. The osteotomy guide includes an indexing feature for aligning the guide with an anatomic landmark and a resection guide for indicating the resection relative to the indexing feature.

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.

Abstract: A method and equipment for producing an antibiotic loaded knee prothesis by custom molding a femoral prothesis in a removable mold from a settable material containing a selected antibiotic, applying the molded prothesis to the distal end of the femur, completing the set of the material to anchor the prothesis to the femur and removing the removable mold. Next a tibial prothesis is custom molded in a second removable mold from a settable material containing a selected antibiotic, the material set and the so formed tibial prothesis is removed from the second mold and is then connected to the proximal end of the tibia in a position to form an articulating joint with the previously molded and applied femoral prothesis.
