3D Matrix
3D Matrix


DJO Surgical has chosen an innovative approach to an industry standard for porous coating on their implant. This coating consists of small, three-dimension (non-spherical) beads. The porous material is either commercially pure titanium or CoCr alloy, depending on the base substrate. The non-spherical shape of the beads provides more points of contact and a much rougher surface area.

Superior Surface Texture

The 3DMatrix porous coating is much rougher and aggressive than spherical beads, providing for more bone apposition. In a canine study for bone ingrowth, 3Dmatrix porous coating outperformed spherical beads.2

Aggressive Porous Coating

The 3DMatrix has a thickness of 0.5mm (a minimum of two bead layers), bead size 180-850 microns, and pore size of 250-450 microns. The porosity volume represents 63.1%. The pore size of 100 to 500 microns has been shown to be optimal; for bone ingrowth.1,2

Acetabular Options

The FMPTM Acetabular System offers a comprehensive line of Acetabular options to fit intraoperative needs and diverse patient anatomy.
