摘要: Tools and methods for implanting hip resurfacing femoral prostheses along a path defined by the axis of a shaped femoral head surface are described. The prostheses are stemless partial ball components having an outer surface shaped to conform to an acetabular socket and may be a two part design having a mating sleeve component with an internal bore adapted to receive the shaped femoral head. The tools and methods are capable of accurately implanting both one and two piece ball components and sleeves without requiring the prosthesis to have a central stem or the preparation of a stem cavity in the femoral head and neck.

摘要: A prosthetic bearing element and a method for forming the same includes an injection molded bearing made of PEEK resin with short carbon fiber reinforcement. The inner surface of the PEEK bearing is adapted to receive a ceramic or metal articulation component. The outer surface of the bearing layer includes sputtered titanium particles forming a porous backing layer. Hydroxyapatite is then sputtered or otherwise deposited onto the titanium backing layer to form an outer surface of the prosthetic bearing element. A barrier layer can be formed either of PEEK or titanium which layer is between the outer surface of the molded bearing and the inner surface of the porous structure. The barrier layer prevents tissue ingrowth into the bearing component. Hydroxyapatite is then sputtered onto the outer porous layer or applied by solution deposition. This outer surface of the prosthetic bearing element can then be coated with bone morphogenic protein.

摘要: A flexible acetabular cup is provided which has an inner bearing surface which comprises a substantially part-spherical portion and two independent arms projecting therefrom. The arms form a separation or opening in the rim of the cup with the external surface of the cup being shaped to cause the independent arms to be pre-stressed towards each other when the cup is inserted in place in a pre-prepared acetabular socket. One way of accomplishing this is to form the cup with the arms bowed outwardly at the time of manufacture.
