Abstract
A prosthetic device for the human hip having elongated fins or other like protrusions which are provided on the underside of a collar and which extend into previously formed slots or grooves in the bone. Either a plurality of fins, or a single fin having a non-rectilinear shape is provided. Apparatus for formation of the grooves in the bone includes a mill guide which can be mounted onto the proximal end of a rasp embedded in a cavity formed in the bone. A milling bit is used in conjunction with the mill guide to form precisely located and shaped grooves into which the fins can seat. A clamp is provided for securing the prosthetic device to the femur while the cement is hardening.
