  • Patent number: 4983183
    Abstract: The present invention relates to a hip prosthesis and a method of implanting the same utilizing dual modes of fixation. The prosthesis has a proximal portion which is porous coated to permit bone ingrowth. The prosthesis also has a distal stem portion which is adapted to be affixed by cementation. In addition, there is a tapering at the junction between the distal stem portion and the proximal portion. The prosthesis is implanted by reaming and broaching the femoral stem of a patient so that it can have a prosthesis' porous portion in contact with the bone proximally and still have channels between the bone and the distal stem portion which are cement filled. In addition this design also allows an improvement in cementation technique by providing an improved bone-cement interlock by more efficient pressurization.
