Abstract
A prosthetic device for the human hip having elongated fins or other like protrusions which are provided on the lower surface 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. In one embodiment, previously formed fins are secured to a lower surface of the collar after formation of the collar. In this embodiment, pegs disposed on the fins preferably reside in correspondingly formed holes in the collar, or reside within slots extending inwardly from outer surfaces of the collar. Alternatively, the fins may be welded or otherwise bonded to the lower surface of the collar.
