The TaperFill Hip Stem design incorporates a proven tapered wedge stem philosophy, integrating a filling proximal geometry to prevent subsidence, an issue that has deterred surgeons from using certain bone-preserving THRs. The immediate inherent stability created by a metaphyseal fill and biological fixation is intended to allow for solid long-term endurance of the implant. TaperFill is the first product fabricated with the new, proprietary P2™ porous coating. Its’ pore size variability is similar to lava rock, which has been demonstrated in studies to provide optimal bone ingrowth.
