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.
