The Foundation Total Hip System has been developed by enhancing proven design features and utilizing simplified instrumentation, thus providing a state-of-the-art system. The Foundation System offers a range of options to best match the individual patient's needs, all with one standard set of instrumentation. The system offers cemented stems with the 450 and 460 series, porous stems with the 470 and 480 series and a press-fit 440 series stem.
• Foundation Total Hip System: Fracture Options
- Three Degree Tapered Geometry
Three degree tapered geometry provides continuous compression to cement mantle. thus allowing the load to be distributed to the bone.
- Enhanced Cobra Flange
The Cobra Flange and normalization arches contribute to medial cement compression while improving the resistance to lateral tensile forces.
- Distal Stem Taper
The gradual taper of the distal stem geometry allows cement to flow over the stem and reduce the likelihood of air bubbles being introduced in to the implant cement interface. The taper allows thicker cement at distal tip resulting in lower cement stresses.
• Clear Cut™ Cement Restrictor
- Completely resorbs within 15 days of surgery.
- Composed of glycerol, gelatin, and water allowing for biocompatibility.
- Provides specific advantages over polyethylene plugs.

• Foundation Total Hip System: Cemented Options
- Enhanced Cement Fixation
. The proximal PMMA Centralizers assure a cement mantle of two millimeters around the entire femoral stem.
. The cobra flange and normalization arches contribute to medial cement compression while improving the resistance to lateral tensile forces.
- Three Degree Tapered Geometry
Three degree tapered geometry provides continuous compression to cement mantle. Thus allowing the load to be distributed to the bone.
- Distal Stem Taper
The gradual taper of the distal stem geometry allows cement to flow over the stem and reduce the likelihood of air bubbles being introduced in to the implant cement interface. The taper allows thicker cement at distal tip resulting in lower cement stresses.

- Innovative Wedge Geometry
Three degree tapered geometry provides continuous compression to cement mantle, thus allowing the load to be distributed to the bone.
- 3DMatrix Porous Coating
3DMatrix® porous coating is manufactured with a commercially pure titanium porous coating. This coating consists of small, three-dimensional (non-spherical) titanium beads: it has a thickness of 0.5mm (a minimum of two bead layers) and is optimal for bone growth.
- Coronal Slot
A coronal slot in the larger sizes assures each stem size maintains a distal stiffness no greater than a 13.5mm diameter stem. Stem stiffness reduction has been shown to the reduction of postoperative thigh pain and stress shielding.
- Rotational Stability
Octagonal distal splines provides an enhanced diaphyseal rotational stability.
