  • Prosthesis for simulating natural kinematics
    Patent number: 9433494
    Abstract: A bearing component 2 for a joint replacement prosthesis comprises a first bearing element 4; a second bearing element 6, and a linking element 8, operatively connecting the first and second bearing elements 4, 6 and permitting relative motion there between. The flexible linking element 8 prevents dislocation of mobile bearings in a total knee replacement prosthesis. The invention also relates to a bridging element which retains the linking element 8 with some play, which acts as a ligament support 2051, and which causes a deflection of the line of action of a ligament 1018. A joint replacement prosthesis is also disclosed comprising a biasing element 1140 or a tensioning element 1220 operatively coupled to the artificial ligament 1018. The biasing element 1140 or tensioning element 1220 may be housed in the stem of a tibia tray 1006.

  • Hip implant
    Patent number: 9427322
    Abstract: Hip implant femoral component includes a stem, say, as a flattened, rounded tapered spike having an upper trunnion with a self-holding taper, which may be symmetrical about the same central axis. A neck—say, as a flattened, curved mass having a lower receptacle with a self-holding taper to receive the stem trunnion, and an upper trunnion with a self-holding taper for holding a ball head with a corresponding receptacle—may be attached. A securing screw for threading into a threaded receptacle of the stem trunnion, which may have a truncated inverse cone head, may be employed to further secure the stem and neck together. The component, especially the stem and neck, or stem, neck and screw, may be made with a nonmagnetic cobalt-chromium-molybdenum alloy exhibiting high strength, wear and corrosion resistance, as a wrought powder metallurgy product, which is essentially if not fully 100% dense.
