Patent ID: 7044976

Claim:
A prosthesis for partial and total replacement of a long bone in humans and animals, said prosthesis comprising: an end component having a longitudinal axis, an inwardly tapered primary recess having an open end, a secondary recess opening onto said primary recess which is offset from said longitudinal axis of said end component and a generally transversely extending cross-hole extending through said end component and having two open ends, one of said open ends of said cross-hole opening onto said primary recess for permitting access thereto by a disassembly tool, a shaft releasably coupled to said end component, said shaft having a longitudinal axis and a first and second end, wherein said first end of said shaft is outwardly tapered and is dimensioned and configured for receipt within said primary recess of said end component, and a projection formed on said first end extending generally longitudinally of said shaft but offset from said axis thereof which is dimensioned and configured for receipt with said secondary recess of said end component and wherein said second end of said shaft has an inwardly tapered primary recess having an open end, a secondary recess opening onto said primary recess which is offset from said longitudinal axis of said shaft and a generally transversely extending cross-hole extending through said shaft having two open ends, one of said open ends of said cross-hole opening onto said primary recess for permitting access thereto by a disassembly tool, and a stem releasably coupled to said shaft, said stem having a longitudinal axis and a first and second end, wherein said first end is intended for engagement in a resected bone having a resected face, and said second end is outwardly tapered and is dimensioned and configured for receipt with said primary recess of said second end of said shaft, and a projection formed on said second end extending generally longitudinally of said stem but offset from said axis thereof which is dimensioned and configured for receipt with said secondary recess of said second end of said shaft; and wherein said shaft, said stem, and said end component are releasably coupled together with said projections and secondary recesses being positioned so as to maintain said end component, said shaft and said stem in a desired angular relationship.
