ABSTRACT:
A metal-to-metal surface hip joint replacement method includes the steps of forming a hard metallic spherical femoral surface replacement prosthesis having a central tapered stem and a mating metallic socket prosthesis, with a sphericity tolerance of about one to three microns, a spacing tolerance of about 100 to 300 microns, and slightly greater spacing at the equatorial zone, mounting a centrally located guide pin on the femoral ball or head, using an apertured relocator guide when needed, using a saw cutoff guide with multiple slots for axial adjustments, using a cylindrical starter drill for initial positioning of the drilling of a tapered central opening, and using a tapered guide pin located in the tapered opening for guiding a chamfering step.
