Abstract:
1. An orthopedic implant comprising: a substrate material adapted to provide the orthopedic implant; a primary friction area located on or integral with said substrate material, said primary friction area having a primary surface having a primary frictional feature; and a secondary friction area located on or integral with said primary surface and defining a secondary frictional feature; said primary friction area and said secondary friction area defining a friction interface zone, said secondary friction area increasing a friction of said primary surface to enhance a frictional engagement between said primary surface and at least one bone; wherein said primary frictional feature defines a plurality of primary teeth; wherein said secondary frictional feature defines a plurality of secondary teeth on or integral with said primary friction area; wherein at least one of said plurality of primary teeth has at least one surface that does not have said secondary frictional feature; wherein said primary friction area and said secondary friction area are at least one of machined, molded, extruded or sintered substrate.
