PÃ‚Â², a new proprietary Titanium Porous coating by DJO Surgical, is the first porous porous coating in the world wherein the non-spherical bead itself is also porous Ã¢â‚¬â€œ giving it its name, P-Squared (PÃ‚Â²). Consisting of variability in pore sizes, very similar to a Ã¢â‚¬Å“lava rockÃ¢â‚¬Â type of structure, P2 aids in the apposition of bone for superior in-growth results.
Rapid Bone In-growth
PÃ‚Â², backed by the largest porous coating animal study in the world, is able to create instant micro-fractures in the trabeculae upon initial bite to the bone, which causes an instantaneous bone in-growth reaction.3 By measuring the axial pull-out force required, P2 demonstrated a minimum 250 pounds of force needed to dissociate the implant from the bone upon immediate implantation at time zero.
Ã¢â‚¬Â¢ P2 is a new proprietary Titanium Porous Coating developed exclusively by DJO Surgical
Ã¢â‚¬Â¢ P2 is the first porous coating in the world wherein the non-spherical bead itself is also porous
Ã¢â‚¬Â¢ P2 provides an initial Ã¢â‚¬Å“biteÃ¢â‚¬Â or Ã¢â‚¬Å“stickÃ¢â‚¬Â to the bone that creates micro-fractures in the trabeculae thus causing immediate bone reaction via WolffÃ¢â‚¬â„¢s law
Ã¢â‚¬Â¢ P2 porous coating has a higher surface roughness than spherical beads and/or newer generations of non-spherical beads, providing for more bone apposition and percent bone in-growth 1,2
Ã¢â‚¬Â¢ P2 exceeds the minimum tensile strength set forth by the FDA by 3 times 1,5
Ã¢â‚¬Â¢ P2 has an average porosity of 60%1
Ã¢â‚¬Â¢ P2 Titanium Porous Coating has been cleared by the FDA for the following applications: Ã¢â‚¬Â¢ Use on acetabular shells
Ã¢â‚¬Â¢ Use on femoral hip stems
Ã¢â‚¬Â¢ Cementless / Bone in-growth THA applications
