P², 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 – giving it its name, P-Squared (P²). Consisting of variability in pore sizes, very similar to a “lava rock” type of structure, P2 aids in the apposition of bone for superior in-growth results.
Rapid Bone In-growth
P², 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.4
P2 is a new proprietary Titanium Porous Coating developed exclusively by DJO Surgical
P2 is the first porous coating in the world wherein the non-spherical bead itself is also porous
P2 provides an initial bite or stick to the bone that creates micro-fractures in the trabeculae thus causing immediate bone reaction via Wolffs law
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
P2 exceeds the minimum tensile strength set forth by the FDA by 3 times 1,5
P2 has an average porosity of 60%1
P2 Titanium Porous Coating has been cleared by the FDA for the following applications:
Use on acetabular shells
Use on femoral hip stems
Cementless / Bone in-growth THA applications
